Part 2 of Sprouting hulled oats

In Sprouting hulled oats, seeds were sprouted at 21°C (70°F) for 3 days. That post ended with a question raised by Oat sprouts analysis regarding desirability of enzymes.

Here’s that study’s analysis of its hulled oat variety’s enzymes, excluding results not pertinent to this post. There was neither a 72-hour measurement period nor a 20°C 60-hour period analyzed. Interpolate measurements accordingly.

1. α-amylase enzyme was described as:

“Alpha-amylase plays a key role during germination since it catalyzes hydrolysis of α-1,4 glucosidic linkages of starch, yielding maltose and glucose necessary for seedling development. Activity of this enzyme increased considerably during oat sprouting [reference to Degree of oat sprouting] but it is also de novo synthesized during this process.

High glucose content in sprouted flour can increase its glycemic index (GI). Foods with low GI are beneficial due to low postprandial glucose response compared to foods with a high GI. Selection of germination conditions is crucial to modulate α-amylase activity in oat for obtaining healthier sprouted flours with lower GI.”

A. 3-day-old hulled oat sprouts probably don’t have “High glucose content.” Studies such as Optimization of Oat Amylase During Sprouting to Enhance Sugar Production found:

“Maltose was the primary sugar, though there was a detectable but smaller amount of glucose.”

B. I understand that researchers have adopted a glycemic index. Does that one dimension indexed on glucose at 100 adequately inform health-choice decisions about oat sprout α-amylase enzyme content?

What’s the point of indexing healthy choices like sprouted whole grains to unhealthy choices that healthy people aren’t going to make anyway?

2. Increased protease enzyme activity was analyzed as desirable, and used as an optimization parameter.

3. Lipase activity increased from 18°C 60-hour to 20°C 96-hour measurements in the above graphic. All sprouted oat lipase levels were below unsprouted control oat flour, however:

“Lipase activity decreased in sprouted var. Meeri flour during germination. Our results suggest that there must be an important lipase activity in oat hull.

Lipase hydrolyse triglicerides to free fatty acids that are prone to oxidation and cause rancidity of cereal flours. According to our results, use of dehulled oat grains is desirable to obtain sprouted oat flours with increased stability and longer shelf life.”

Don’t know which enzyme is responsible for mild throat burn after eating 3-day-old hulled oat sprouts. It isn’t unpleasant, just unexpected. Research so far indicates that people pay for catalytic enzymes that increase proteolytic and digestive activity.

What if we index health decisions on a standard at 100 of drinking a beer first thing in the morning? Would anything scaled by that one dimension inform fine tuning of health-choice decisions?

“Woke up this morning and I got myself a beer
The future’s uncertain and the end is always near”

A case for carnitine supplementation

This 2020 review subject was carnitine, acetyl-L-carnitine, and its other molecular forms:

“Carnitine is necessary to deliver long-chain fatty acids from cytosol into mitochondria. Carnitine homeostasis is maintained by diet and renal absorption, as only a small amount (about 25%) is obtained by endogenous biosynthesis.

Defective fatty acid oxidation occurs with reduced intracellular levels of carnitine, leading to glucose consumption instead of lipid consumption, resulting in hypoglycemia. Non-metabolized lipids accumulate in tissues such as heart, skeletal muscle, and liver, resulting in myopathy and hepatic steatosis.

2000 mg/day is unlikely to provoke unwanted side effects and is safe for humans. In-depth studies are needed to identify a unique method of analysis which can guarantee efficient monitoring of supplement active component amounts.” “The Nutraceutical Value of Carnitine and Its Use in Dietary Supplements”

The review listed animal studies of L-carnitine alone and in combination with:

  • Vitamin D3;
  • Coenzyme Q10;
  • Nicotinamide riboside;
  • Selenium;
  • L-arginine;
  • Anti-histamine drugs cetirizine hydrochloride and chlorpheniramine maleate; and
  • Hypertension drug olmesartan.

Human studies of its effects included:

  • Muscle soreness, damage biomarkers, and cramps;
  • Osteoarthritis knee pain and inflammation markers;
  • Ischemic cerebrovascular injury;
  • Peripheral neuropathy;
  • Nonalcoholic fatty liver disease;
  • Insulin resistance and Type 2 diabetes;
  • Kidney diseases;
  • Inherited diseases phenylketonuria and maple syrup urine;
  • Stress, depression, and anxiety;
  • Male infertility; and
  • Hepatitis C.

Sprouting hulled oats

My Sprouting whole oats trial was a hassle with hulls and a poor germination rate. This week I used hulled oat seeds from a different vendor, and a different study, Degree of oat sprouting, as my model.

  • Oat variety of Avena sativa was a small seed, 7 mm x 2 mm. The model used “huskless oat ‘Gehl'” which is a different species (Avena nuda).
  • 100 seeds weighed 1.5 grams. There were over 1,300 seeds per 20 g batches.
  • Oat sprout batches were processed the same way I do broccoli sprout batches. A new batch started soaking to start germination every 12 hours, then was rinsed three times every 24 hours on a 6 hours – 6 hours – 12 hours cycle. I have an open question to the model’s corresponding coauthor to explain their “4.5‐hr wet steeping, 19‐hr air rest, and 4‐hr steeping, all at 20°C” procedures to start germination, since I didn’t have access to its cited study. The model grew oat sprouts for 1, 2, and 3 days.
  • Temperature in my kitchen was 21°C (70°F) because it’s winter outside. The model grew oat sprouts at 10, 14, 20, 25, and 30°C. Their findings included “Temperatures between 20° and 25°C yielded the most dramatic changes in properties of sprouted oats.”

I evaluated germination results per the model’s Degree of Sprouting finding:

“Length of the coleoptile [shoot] was selected as a criterion of categorization of degree of sprouting. Grains of degree 0 do not show any radicle [root] or coleoptile growth. Degree:

  1. Has visible embryos (small white point), while radicles and coleoptile are not visible;
  2. Shows a developed embryo emerging from the seed coat;
  3. Coleoptile lengths of at least half the oat grain length;
  4. Coleoptile lengths between half and a full grain length; and
  5. Coleoptile longer than a full grain length.”

Most of this trial wasn’t a big deal, adding just a few extra minutes onto what I do three times a day with broccoli sprouts. Here’s what this oat variety’s hulled seeds and 3-day-old sprouts looked like:

The tedious part was evaluating degrees of sprouting. I took as large a bottom-to-top sample as I could tolerate sorting (235 seeds / sprouts, about 17%), with these results:

A 97% germination rate. 🙂 Average weight of three 3-day-old batches was 51.9 grams, for a 260% weight gain. My 5-day-old whole oat sprouts trial had a 22% germination rate and a 221% weight gain.

The model’s Figure 3 Degree of Sprouting finding for 20°C and 25°C at 3 days was hard to read:

Don’t know how 0 degrees of sprouting at 20°C and 25°C > 1% reconciled with their statement “Germinability after 3 days was about 99% at all temperatures.” A numerical table wasn’t provided – yet another question for the corresponding author. Meanwhile, I’ll estimate:

Their hard-to-read Figure 3 also wasn’t completely congruent with their statement:

“Around 20% of grains sprouted at 20° and 25°C had a coleoptile longer than a full grain length (degree of sprouting 5).”

These oat sprouts taste milder than my previous trial’s. With more than a third at a degree-of-sprouting 5 measurement, they’re sweet, concurrent with the model’s findings that:

“Increased amounts of reducing sugars and ascorbic acid were found particularly in the radicles and coleoptile. Coleoptile and radicle growth (input parameters for the degree of sprouting) and reducing sugars and α‐amylase activity are interdependent.”

Corresponding increased enzyme concentrations produce an aftertaste, though. I eat them along with either food or drink.

Can eating three-day-old oat sprouts of this Montana cultivated variety help with what I’m already doing? Here’s what I expect, given the model was a different oat species, and the Sprouting oats and Oat sprouts analysis studies used different oat cultivars.

1. In order of magnitude: increased antioxidants, GABA, phenolic compounds, protein, amino acids, β-glucan, and polyunsaturated fatty acids. Don’t know about GABA and protein, but the others may help counter inflammation.

2. Increased enzyme intake. The model study used α-amylase as a marker for α-amylase enzymes (catalyze starches), protease enzymes (catalyze proteins), and lipase enzymes (catalyze fats).

Oat sprouts analysis characterized increased α-amylase and lipase activities as undesirable in a sprouted oat flour context. More on enzymes in Part 2 of Sprouting hulled oats.

Continue sleepwalking, young people

A few months ago I had a series of interactions with a late-twenties person who’d escaped from Manhattan. They were well-off enough to work remotely from anywhere, but they chose to move into their mother’s house.

I tried to see them as an individual. I presented Wake up, young people!! arguments:

“Your future lives are being destroyed by this worldwide political power grab.

Unless you were / are already seriously ill with some other disease, you have had / will have very little chance of becoming a COVID-19 fatality.

Young people have been forced into receiving no benefits to their present lives in order to receive less than nothing in their future lives!

  • People who are herding you couldn’t care less about you.
  • Their control over you has no current or future benefit to you. They’ve demonstrated that your present and future lives mean nothing to them.
  • Sitting around, doing nothing, is interpreted as you consenting to their actions.”

None of these had any obvious penetration to the shields they had. They tried to stereotype me for my efforts.

I presented “taking responsibility for your own one precious life” evidence. They knew I’d been in Milan, Italy, February 22-23, 2020, the weekend during which ten towns were closed south of the city.

They tried to ridicule me for saying that anything I’d done to prepare for an aging life stage – since they’d been in elementary school – had any effect on me not becoming infected. Their behavioral contagion was that strong, as if their survival depended on not hearing anything I had to say.

Take a look at I’m kind of asleep right now while it’s still up on YouTube. The young people I work with aren’t like that, but this phenotype is apparently in the majority.

Does running with the herd feel safe? For now?

Week 37 of Changing to a youthful phenotype with broccoli sprouts

1. Been wrong about a few things this past week:

A. I thought in Week 28 that extrapolating A rejuvenation therapy and sulforaphane results to humans would produce personal results by this week. An 8-day rat treatment period ≈ 258 human days, and 258 / 7 ≈ 37 weeks.

There are just too many unknowns to say why that didn’t happen. So I’ll patiently continue eating a clinically relevant 65.5 gram dose of microwaved broccoli sprouts twice every day.


The study’s lead researcher answered:

“Depends, it might take 37 weeks or more for some aspects of ‘youthening’ to become obvious. It might even take years for others.

Who really cares if you are growing younger every day?

For change at the epigenomic/cellular level to travel up the biological hierarchy from cells to organ systems seems to take time. But the process can be repeated indefinitely (so far as we know) so by the second rejuvenation you’re already starting at ‘young’. (That would be every eight to ten years I believe.)”

His framework is in An environmental signaling paradigm of aging.

B. I thought that adding 2% mustard seed powder to microwaved broccoli sprouts per Does sulforaphane reach the colon? would work. Maybe it would, maybe it wouldn’t, but my stomach and gut said that wasn’t for me.

C. I thought I could easily add Sprouting whole oats to my routine. I ran another trial Sprouting hulled oats using oat seeds from a different company and Degree of oat sprouting as a model.

2. Oat sprouts analysis paired studies were very informative, don’t you think? One study produced evidence over a range of germination parameters (hulled / dehulled seeds of two varieties, for 1-to-9 days, at 12-to-20°C). And evaluated what mix of germination parameters would simultaneously maximize four parameters (β-glucan, free phenolic compounds, protease activity and antioxidant capacity) while minimizing two (enzymes α-amylase and lipase). Then a follow-up study characterized oat seeds sprouted under these optimal conditions.

I doubted PubMed’s “oat sprout” 20 search results for research 1977 to the present. Don’t know why they didn’t pick up both of these 2020 studies, but I’m sure that .gov obvious hindrances to obtaining relevant information like this won’t be fixed. What other search terms won’t return adequate results?

3. The blog post readers viewed this week that I made even better was Do delusions have therapeutic value? from May 2019. Sometimes I’ve done good posts describing why papers are poorly researched.

4. I’ve often changed my Week 4 recipe for an AGE-less Chicken Vegetable Soup dinner (half) then the next day for lunch. The biggest change brought about by 33 weeks of behavioral contagion is that I now care more about whether vegetables are available than whether or not they’re organic. Coincidentally, I’ve developed a Costco addiction that may require intervention.

  • 1 lemon
  • 3 Roma tomatoes
  • 4 large carrots
  • 6 stalks organic celery
  • 6 mushrooms
  • 6 cloves garlic
  • 6 oz. organic chicken breast fillet
  • 1 cup organic pasta
  • 1 yellow squash, alternated with 1 zucchini
  • 1 cup sauvignon blanc
  • 32 oz. “unsalted” chicken broth, which still contains 24% of the sodium RDA

Pour wine into a 6-quart Instant Pot; cut and strain squeezed lemon; cut chicken into 1/4″ cubes and add; start mixture on Sauté. Wash and cut celery; wash and scrub carrots; stir pot at 4 minutes; stir in celery at 5 minutes.

Cut and stir in carrots. Wash mushrooms, slicing only if supersized. When pot boils around 10 minutes, add chicken broth and stir.

Wash and slice yellow squash / zucchini; crush and peel garlic but don’t slice. When pot boils again around 15 minutes, stir in pasta; turn off pot.

Add yellow squash / zucchini, mushrooms, garlic; wash and add whole tomatoes. Let set for 20 minutes; stir bottom-to-top 5 and 15 minutes after turning off, and again before serving.

AGE-less Chicken Vegetable Soup is tasty enough to not need seasoning, at least when freshly prepared.

Oat sprouts analysis

A research group published two 2020 studies on sprouting oat seeds. Their first study produced evidence over a range of germination parameters (hulled / dehulled seeds of two varieties, for 1-to-9 days, at 12-to-20°C):

“The aim was to investigate the influence of germination period and temperature on protein profile, bioactive potential (β-glucan and phenolic contents), antioxidant capacity, and on activity of enzymes (α-amylase, protease and lipase) from hulled and dehulled oat varieties. Multi-response optimization was used to identify optimal germination conditions that maximize sprouted oat flour quality.

  • Hulled (variety Barra) and dehulled (variety Meeri) germination was performed in dark at different temperatures (12, 14, 16, 18, and 20 ◦C) and duration (24, 60, 96, 156, and 216 h).
  • Germination at 16 ◦C for 216 h and 20 ◦C for 96 h produced the highest protein accumulation in varieties Barra and Meeri, respectively.
  • Germination for short periods (24–96 h) combined with medium temperatures (12–16 ◦C) retained β-glucan levels, but longer germination times (156–216 h) caused reductions of 47–64%. Endogenous β-glucanases increase activity during germination, causing hydrolysis of β-glucan.
  • Free phenolic compound content was between 1.6-fold and 2.8-fold higher when germination took place at high temperatures (16–18 ◦C) for longer times.
  • Antioxidant capacity was between 1.4 and 4.5-fold higher. High temperatures (16–18 ◦C) and longer germination times (156–216 h) positively influenced antioxidant capacity.

The effect of germination conditions strongly depended on genetic diversity and presence/absence of hull.

Optimal germination conditions maximize contents of β-glucan, free phenolic compounds, protease activity, and antioxidant capacity, and minimize activity of undesirable enzymes α-amylase and lipase. For variety Meeri, that corresponded to 18 ◦C and time 120 h.” “Changes in protein profile, bioactive potential and enzymatic activities of gluten-free flours obtained from hulled and dehulled oat varieties as affected by germination conditions” (not freely available)

Their second 2020 study analyzed properties of 4-day-old oat sprouts. Dehulled oat seeds (variety Meeri) were soaked at room temperature for 4 hours, then germinated in darkness at 18°C with humidity ≥ 90%.

“Sprouted oat powder was an excellent source of protein (10.7%), β-glucan (2.1%), thiamine, riboflavin, and minerals (P, K, Mg and Ca). It presented better amino acid and fatty acid compositions, and levels of γ-aminobutyric acid [GABA], free phenolics, and antioxidant capacity than control.

Protein content (g/100 g) and amino acid profile (g/100 g protein). Different letters within a row indicate p ≤ 0.05 statistical differences.

During germination, proteins are partially hydrolyzed increasing availability of free amino acids. Activity of glutamate decarboxylase enzyme is enhanced.

However, no significant reduction of glutamate content was observed. Glutamate is used for GABA and protein synthesis, but it is also produced by protein hydrolysis, glutamine synthetase-glutamate synthase cycle, and GABA transaminase reactions.

Sprouted oat powder exhibited 2.5-fold higher SPC [soluble (free) phenolic compounds] levels. De novo synthesis of phenolic compounds or liberation of phenolic compounds that are linked to macromolecules due to cell wall dismantling during germination could explain enhancement of SPC.

Sprouted oat powder displayed a 3-fold higher antioxidant capacity. Release of bound phenolic compounds and de novo synthesis of avenanthramides might be responsible.

Hydrolysis of β-glucan might also cause an increase in oxygen radical absorbance capacity. β-glucan oligosaccharides exhibit high radical scavenging activity and reducing power, and that could be related with exposure of their active hydroxyl groups and decrease of intermolecular hydrogen bonding during germination.” “Sprouted oat as a potential gluten-free ingredient with enhanced nutritional and bioactive properties” (not freely available)

Both studies started germination by:

“Twenty grams of oat seeds were used for germination. Soaking (1:6 ratio, w/v) was performed at room temperature (20 ◦C ±2 ◦C) for 4 h.”

Neither study included estimates of germination rates. I contacted the corresponding coauthor for that information, and they replied:

“The germination rate in hulled oat varieties was around 95% and in
dehulled one around 55-70% depending on the germination conditions.”

Sprouting whole oats

Last week I started sprouting whole oats using Sprouting oatsfirst study as a model.

  • Oat seed variety was Thunder Acres Organic Oats Lot# DEC 07 2022, sized .3 cm x 1.1 cm. That’s a large seed by criteria of large not passing through a 2.65 mm x 8.33 mm sieve.
  • 100 seeds weighed 4.2 grams. There were almost 600 seeds per 25 g batches.
  • Oat sprout batches were processed the same way I do broccoli sprout batches. A new batch started soaking to start germination every 12 hours, then was rinsed three times every 24 hours on a 6 hours – 6 hours – 12 hours cycle. The model also soaked seeds for 12 hours, but watered daily.
  • Temperature was 21°C (70°F) compared with the model’s 25°C. Relative humidity was lower than their 60%, probably between 30% and 50%, because it’s winter outside.

A few sprouts were similar to the model’s radicle length of 6.47 ± 0.22 cm after five days of germinating in darkness:

Didn’t achieve anything close to their 100% germination rate:

Not sure why 78% of seeds didn’t overcome dormancy. Different oat variety? Half the model’s relative humidity? Four degrees cooler temperature? Too frequent watering?

I decided to continue on to 6-day-old oat sprouts. A few sprouts had a growth spurt and started greening:

Just a few, though:

Didn’t generate enough data to confirm significant differences in germination rates between 5 and 6 days, or between a.m. and p.m.

Removing each batch’s sprout hulls was tedious. Now I can cut my fingernails again.

I ran another trial Sprouting hulled oats using oat seeds from a different company and Degree of oat sprouting as a model.

Degree of oat sprouting

This 2019 study investigated oat sprout parameters:

Huskless oat ‘Gehl’ cultivated in 2016 in Canada, was used throughout the study. Grains (500 g) were sprouted at different temperatures (10, 14, 20, 25, and 30°C) and for different times (1, 2, and 3 days). Changes in vitamin C, β‐glucan, and reducing sugar were monitored, and α‐amylase activity was studied as a marker for total enzyme activity.

Mass fraction of radicle [root] and coleoptile [shoot] in grain correlated very well with β‐glucan level. A similarly good correlation was found for the much easier applicable degree of sprouting, visual assessment of coleoptile length set into relation to grain size.

Germinability after 3 days was about 99% at all temperatures. Temperatures between 20° and 25°C yielded the most dramatic changes in properties of sprouted oats.

  • At 3 days, α‐amylase activities at 20° and 25°C increased significantly to values one order of magnitude larger than those for other temperatures.
  • β‐glucan content was decreased after 3 days at all temperatures. Degradation was most pronounced at 20°C, almost halving initial β‐glucan content to 3.9%.
  • No ascorbic acid was present in native grain. Upon sprouting, a significant increase in ascorbic acid content was found – except at 30°C – with highest levels at 20°C.

Ascorbic acid content in radicles and coleoptile was four times higher than that in grain without radicles and coleoptile. Oat grains sprouted for 3 days at 20°C had an average degree of sprouting of 3; hence, radicles and coleoptile contributed about 8% of mass. These findings indicate that a fast visual determination of degree of sprouting allows to estimate, for example, ascorbic acid content without doing expensive experiments.

Around 20% of grains sprouted at 20° and 25°C had a coleoptile longer than a full grain length (degree of sprouting 5). Less long coleoptiles developed at other temperatures.

  • For the 3‐day sprouting period, the longest coleoptile was observed for sprouting at 25°C.
  • At 30°C average degree of sprouting was 1.4, and grains showed no practical radicle growth.

Coleoptile and radicle growth (input parameters for the degree of sprouting) and reducing sugars and α‐amylase activity are interdependent. Degree of sprouting could develop into a reliable characterization method for sprouted grains, usable for predicting compositional and nutritional changes of oats during sprouting.” “Sprouting of oats: A new approach to quantify compositional changes”

Relative humidity wasn’t mentioned in this study. I asked the corresponding coauthor about it, since two Sprouting oats studies stated relative humidity as a factor for sprouting oats.

I also asked them to explain their “4.5‐hr wet steeping, 19‐hr air rest, and 4‐hr steeping, all at 20°C” procedures to start germination, since I didn’t have access to the cited study. No reply yet.

This was my model study for Sprouting hulled oats.

An oats β-glucan clinical trial

This 2020 human study investigated effects of processing β-glucan:

“Nutritional advantages of oats compared to many other grains include gluten-free nature, high content of polyunsaturated fatty acids, protein composition which complements that of pulses, and substantiated health effects of fibers, specifically oat β-glucan. Novel oat products, which are often semi-solid or liquid, generally need alterations of the physicochemical properties of oats.

The hypothesis in this study [Clinical trial NCT02764931] was that bioprocessing of oat bran with enzyme treatment, causing depolymerization of β-glucan, affects nutritional properties of bran and functional properties of β-glucan in human gastrointestinal tract.

The study meal consisted of oat bran concentrate treated with a commercial food-grade cell wall degrading enzyme preparation at 1 or 50 nkat β-glucanase g-1 dm-1. A control sample was prepared in the same way without added enzymes. Average MW [molecular weight] of β-glucan in:

  • Control oat bran concentrate was >1000 kDa [weight in kilodaltons] (High MW);
  • 1 nkat g-1 dm-1-treated 524 kDa (Medium MW); and
  • 50 nkat g-1 dm-1-treated 82 kDa (Low MW).

Results of this study supported the hypothesis that alteration of oat β-glucan MW with enzymatic treatment affects nutritional properties of oat bran and functional properties of β-glucan in the human gastrointestinal tract:

  • A High MW β-glucan meal resulted in the highest excretion of fecal bile acids, and the lowest excretion of phenolic compounds in urine.
  • A Low MW β-glucan meal resulted in the lowest excretion of fecal bile acids, but the highest excretion of phenolic compounds, especially ferulic acid, in urine.
  • Medium MW β-glucan was similar to High MW β-glucan in that it resulted in high excretion of fecal bile acids and low excretion of phenolic compounds to urine, but mean pressure in the duodenum was closer to Low MW than to High MW meal.

Perceived gut well-being after consumption of each meal did not differ between meals, but varied between genders, which should be further investigated.” “Effect of oat β-glucan of different molecular weights on fecal bile acids, urine metabolites and pressure in the digestive tract – A human cross over trial” (not freely available)

I eat 81 grams of steel-cut oats every morning, which is represented by this study’s high-molecular-weight control. Later I take a 400 mg β-glucan capsule for immune system benefits.

Take responsibility for your one precious life.

No β-glucan for dolphins or seagulls

A broccoli sprouts study that lacked evidence for human applicability

A 2020 study Combined Broccoli Sprouts and Green Tea Polyphenols Contribute to the Prevention of Estrogen Receptor–Negative Mammary Cancer via Cell Cycle Arrest and Inducing Apoptosis in HER2/neu Mice (not freely available) conclusion was:

“Lifelong BSp [broccoli sprouts] and GTP [green tea polyphenol] administration can prevent estrogen receptor–negative mammary tumorigenesis through cell cycle arrest and inducing apoptosis in HER2/neu mice.”

These researchers had unaddressed insufficiencies in this study that were also in their 2018 study as curated below. The largest item that required translation into human applicability was rodent diet content of 26% “broccoli sprout seeds.”

You may be surprised to read the below previous study’s unevidenced advice to eat double the weight of broccoli sprouts that I eat every day. You won’t be surprised that it’s not going to happen. Especially when no alternatives were presented because rodent diet details weren’t analyzed and published.

Sulforaphane is an evolved defense mechanism to ward off predators, and eating it is evolutionarily unpleasant. Will people in general and pregnant women in particular eat a diet equivalent to 26% “broccoli sprout seeds?”

Where were peer reviewer comments and researcher responses? Are these not public as they are by all Open Access journals hosted on

Sponsors and researchers become locked into paradigms that permit human-inapplicable animal research year after year. What keeps them from developing sufficient human-applicable evidence to support their hypotheses?

This 2018 Alabama rodent study investigated the epigenetic effects on developing breast cancer of timing a sulforaphane-based broccoli sprouts diet. Timing of the diet was as follows:

  1. Conception through weaning (postnatal day 28), named the Prenatal/maternal BSp (broccoli sprouts) treatment (what the mothers ate starting when they were adults at 12 weeks until their pups were weaned; the pups were never on a broccoli sprouts diet);
  2. Postnatal day 28 through the termination of the experiment, named the Postnatal early-life BSp treatment (what the offspring ate starting at 4 weeks; the mothers were never on a broccoli sprouts diet); and
  3. Postnatal day 56 through the termination of the experiment, named the Postnatal adult BSp treatment (what the offspring ate starting when they were adults at 8 weeks; the mothers were never on a broccoli sprouts diet).

“The experiment was terminated when the mean tumor diameter in the control mice exceeded 1.0 cm.

Our study indicates a prenatal/maternal BSp dietary treatment exhibited maximal preventive effects in inhibiting breast cancer development compared to postnatal early-life and adult BSp treatments in two transgenic mouse models that can develop breast cancer.

Postnatal early-life BSp treatment starting prior to puberty onset showed protective effects in prevention of breast cancer but was not as effective as the prenatal/maternal BSp treatment. However, adulthood-administered BSp diet did not reduce mammary tumorigenesis.

The prenatal/maternal BSp diet may:

  • Primarily influence histone modification processes rather than DNA methylation processes that may contribute to its early breast cancer prevention effects;
  • Exert its transplacental breast cancer chemoprevention effects through enhanced histone acetylation activator markers due to reduced HDAC1 expression and enzymatic activity.

This may be also due to the importance of a dietary intervention window that occurs during a critical oncogenic transition period, which is in early life for these two tested transgenic mouse models. Determination of a critical oncogenic transition period could be complicated in humans, which may partially explain the controversial findings of the adult BSp treatment on breast cancer development in the tested mouse models as compared the previous studies. Thus long-term consumption of BSp diet is recommended to prevent cancers in humans.”

“The dietary concentration for BSp used in the mouse studies was 26% BSp in formulated diet, which is equivalent to 266 g (~4 cups) BSp/per day for human consumption. The concentration of BSp in this diet is physiological available and represents a practical consumption level in the human diet.

Prior to the experiment, we tested the potential influences of this prenatal/maternal BSp regimen on maternal and offspring health as well as mammary gland development in the offspring. Our results showed there was no negative effect of this dietary regimen on the above mentioned factors (data not shown) suggesting this diet is safe to use during pregnancy.”

I didn’t see where the above-labelled “Broccoli Sprout Seeds” diet content was defined. It’s one thing to state:

“SFN as the most abundant and bioactive compound in the BSp diet has been identified as a potent HDAC inhibitor that preferably influences histone acetylation processes.”

and describe how sulforaphane may do this and may do that, and include it in the study’s title. It’s another thing to quantify an animal study into findings that can help humans.

The study’s food manufacturer offers dietary products to the public without quantifying all contents. Good for them if they can stay in business by serving customers who can’t be bothered with scientific evidence.

Any difference between the above-labelled “Broccoli Sprout Seeds” and broccoli seeds? Where was any evidence that “Broccoli Sprout Seeds” and SPROUTED “Broccoli Sprout Seeds” were equivalent per this claim:

“Equivalent to 266 g (~4 cups) BSp/per day for human consumption. The concentration of BSp in this diet is physiological available and represents a practical consumption level in the human diet.”

To help humans, this animal study had to have more details than the food manufacturer provided. These researchers should have either tasked the manufacturer to specify “Broccoli Sprout Seeds” content, or contracted out analysis if they weren’t going to do it themselves.

Regarding timing of a broccoli sprouts diet for humans, this study didn’t provide evidence for recommending:

“Long-term consumption of BSp diet is recommended to prevent cancers in humans.” “Temporal efficacy of a sulforaphane-based broccoli sprout diet in prevention of breast cancer through modulation of epigenetic mechanisms”

Sprouting oats

Three 2020 studies investigated properties of sprouted oats. This first study compared one oat cultivar’s seed and sprout contents for phenolic compounds, and evaluated oat sprouts’ protection against developing colon cancer:

“The purpose of this investigation was to evaluate whether sprouted oats (SO) of the Turquesa variety still possessed effective physiologically bioactive compounds, i.e., phenolics, flavonoids, AVAs [avenanthramides], and phytosterols, and whether it exerted antioxidant and anti-inflammatory effects, as well as the capacity to improve relevant intestinal parameters, in an AOM [azoxymethane] / DSS [dextran sulfate sodium]-induced CRC [colorectal cancer] mouse model.

Suboptimal intake of whole grains (38 g/d) was associated with CRC burden across 16 European countries. An optimal intake of 50–100 g/d was considered in our study to establish the dose administered in the AOM/DSS-induced CRC mouse model (75 g/d).

Seeds (100 g) were soaked in distilled water for 12 h then watered daily. Temperature and relative humidity were set at 25 °C and 60%. Germination was performed in darkness for five days. Germination percentage was determined based on total number of fully emerged seedlings.

We reached 100% of germination and a radicle length of 6.47 ± 0.22 cm. Sprouts were dried at 50 °C for 12 h, milled to a particle size of 0.5 mm, and stored at 4 °C until analyses.

Protein and lipid contents were higher in SO, whereas carbohydrate and ash contents were lower. A more than four-fold increase [0.64 mg/g to 2.79 mg/g] in TPC [total phenolic compounds] was obtained after five days.

We identified AVA-D as the most abundant AVA, followed by AVA-L, which had not been reported as one of the three most abundant AVAs in other oat varieties. Of the three most abundant AVAs previously reported, only AVA-B had a higher abundance in germination.

Phytic acid, an antinutritional compound present in oats, was 10 times lower in oat sprouts. Phytic acid has its content decreased by 15%–35% during even a short three-day germination due to activation of phytase activity. Although high doses of phytic acid inhibit absorption of metals and minerals in humans, it has been observed that, in small doses, it can function as a protective factor in several chronic degenerative diseases.

Mice in groups 3 and 4 were gavaged every morning with phenolic-AVA extract (0.084 mg GAE) and 30 mg of SO, respectively. We observed a mild anti-inflammatory effect of SO and AVA treatments, and a reduced adenocarcinoma incidence of 52.5% and 21.3%, respectively.

SO was more efficient in activating the Keap1-Nrf2 signaling pathway compared to treatment with AVA. Oat phenolic compounds together with β-glucans may be acting synergistically, thus offering greater protection for cancer prevention and treatment.” “Chemopreventive Effect of the Germinated Oat and Its Phenolic-AVA Extract in Azoxymethane/Dextran Sulfate Sodium (AOM/DSS) Model of Colon Carcinogenesis in Mice”

The supplementary material developed this oat cultivar’s seed and sprout profiles for 138 phenolic compounds. It measured C-type AVAs, but not A-type AVAs.

This was my model study for Sprouting whole oats.

A second study was reviewed in Eat oats today! and repeated here:

“The first evaluation of anti-inflammation effects of A-type AVAs was published from our own group. Fifteen A-type AVAs from commercial sprouted oat products interacted with lipopolysaccharide-induced nitric oxide production and iNOS expression.” “Quantitative Analysis and Anti-inflammatory Activity Evaluation of the A-Type Avenanthramides in Commercial Sprouted Oat Products” (not freely available)

Oat variety and sprout age weren’t available for the six sprouted oat products tested, so oat seed-to-sprout comparisons weren’t possible. A-type AVA comparisons among products were performed, but weren’t meaningful due to unknown varieties, ages, product processing, and storage.

A third study compared four grains’ sprouted and unsprouted contents:

“Seeds were soaked at 25°C in 1 L of distilled water for 20 (brown rice), 12 (sorghum and millet) and 8 h (oat), respectively. Hydrated grains were allowed to germinate with layering over wet cellulose pads in a humid chamber for 60 h at 25°C (oat seeds) or 30°C (brown rice, sorghum, and millet seeds) with 95% relative humidity.

All seeds derived from brown rice and oat were germinated after 48 h in the humid chamber. Germinated grains were dried at 50°C until reaching a moisture content of 10%. Sample seeds were milled to fine flour, screened through a 100-mesh sieve and stored at 4°C for further analysis.

After 60 h of germination, sprout length in sorghum and millet ranged from 8 to 24 mm, while sprouts obtained from brown rice and oat ranged from 3 to 6 mm.

Compared to raw flours, germinated flours derived from brown rice, sorghum, and millet had lower gelatinization enthalpy, whereas germinated oat flour showed higher gelatinization enthalpy.

During germination, enzymes are activated, catalyzing starch degradation, which may disrupt the double helical structure of starch. Consequently, less energy is required to unravel and melt double helices of starch in germinated flours. The increase in gelatinization enthalpy of germinated oat flour may be due to dissolution of hydrolyzed starch granules during germination.” “Influence of germination on physicochemical properties of flours from brown rice, oat, sorghum, and millet” (not freely available)

The first study sprouted oats for five days to full germination and a minimum radicle length of 6.25 cm. The third study sprouted oats to full germination in 60 hours and a 3 mm minimum total length.

At the same 25°C, with 60% relative humidity and daily watering, it took 120 hours to achieve full germination. With 95% relative humidity, it took half that time.

Was humidity a relevant difference in oat sprout growth? Would Choyang variety oat sprouts increase their minimum 3 mm total length more than 20 times between Hours 60 and 120 to match the minimum Turquesa radicle length?

This is a count of PubMed “oat sprout” search results, 20 results total:

A “broccoli sprout” search returned 648 results. Is oat sprout research just getting started?

Part 2 of The transgenerational impact of Roundup exposure

This 2020 study followed up The transgenerational impact of Roundup exposure using the Washington State Unversity research group’s most recent methodology in DEET and permethrin cause transgenerational diseases:

“The herbicide glyphosate has been shown to promote epigenetic transgenerational inheritance of pathology and disease in subsequent great-grand offspring (F3 generation). The current study was designed to identify epigenetic biomarkers for glyphosate-induced transgenerational diseases using an epigenome-wide association study.

Pathologies investigated included prostate disease [13 of 44 subjects], kidney disease [11 of 44], obesity [19 of 45], and presence of multiple disease [10 of 45]. Sperm were collected from F3 glyphosate lineage males and used to identify specific differential DNA methylation regions (DMRs) and differential histone retention sites (DHRs).

The number of DHRs were less than the number of DMRs, and DHRs were found to have disease specificity. The combination of DMRs and DHRs is anticipated to facilitate pathology diagnosis.

Low sample number is a limitation in the current analysis. Potential higher variability in data needs to be considered.

This is one of the first observations of DHRs as potential biomarkers for disease. The current study used glyphosate induction of transgenerational disease as a proof of concept such environmental biomarkers can be identified and potentially used as diagnostics for disease susceptibility in the future.” “Epigenome-wide association study for glyphosate induced transgenerational sperm DNA methylation and histone retention epigenetic biomarkers for disease”

Reverberations, harmonics, history

Catching up with Martin Armstrong from 2012:

“Corruption within the Roman Republic was certainly at its peak during the first century BC. There was a brewing debt crisis in Rome and the oligarchy was determined to keep power at any cost. Corruption was so widespread that interest rates doubled from 4% to 8% for the elections of 54 BC because there was so much bribery going on to gain votes.

Caesar was clearly a Popularis, a man of the people who stood against the corruption of the Republic. Like today, we have no real voting control over the fate of the nation. Those who are in charge of the political machine control the real political state.

Caesar knew who his enemies truly were. He clung to his belief that if the majority of the Senate were free of the Oligarchy of Cato and Cicero, they would surely see the light. To persuade them, Caesar wrote his seven books on his truly remarkable conquest of Gaul.

Cato and his Oligarchy were so intensely anti-Caesar that they were willing to do anything to anybody. But this was a moment in time where the corruption had simply gone too far.

By September 29th, 51 BC, Caesar ran out of civilized options. Crossing the Rubicon became the only option.

Janus was the symbol of a cyclical change, the departing of one era and the birth of another. His shrine consisted of two doorways that traditionally were left open in time of war and kept closed when Rome was at peace. Leaving the doors open in time of war symbolized the new era that was possible.

Property values were collapsing. Debts were excessive. Those who held mortgages refused to accept just the property back.

Caesar dealt with this major extraordinary situation in a truly astonishing manner, realizing that assets and money are in a union of opposing forces, yet bound together. Value of property is not a constant relationship for money itself is not like a ruler.

Money is more akin to a rubber band even when it may be gold or silver. Money is like everything else – subject to the whims of supply and demand.

The economy is a dynamic relationship between everything with no real constant. We are at a tremendous disadvantage because we have grown up thinking in a flat linear world that does not exist. We limit ourselves by thinking in money,

Caesar explained that he had to borrow to fund the war and it was unethical for him to cancel all debts since he himself would benefit. Generals come and go, but true economic reformers of the state to save the nation are rare indeed. Caesar paid for his economic reform with his life.

There can be no greater example of political corruption that required desperate reform than the calendar. Caesar replaced the typical lunar year and introduced his new calendar based on 365¼ solar days on January 1st, 45 BC.

Sulla [138 – 78 BC] was a highly original, gifted and skillful general, never losing a battle. His rival described Sulla as having the cunning of a fox and the courage of a lion – but that it was the former attribute that was by far the most dangerous. This mixture was later referred to by Machiavelli in his description of the ideal characteristics of a ruler.

Sulla was more interested in retaining institutes of government while eliminating people occupying them whereas Caesar was far more compelled to act to restore institutions and to spare people, even his more threatening enemies. These are not actions of a man interested in personal power, but a man interested in saving his country.

You live in an oligarchy no different today than what Caesar faced back then. One maxim always holds true; Absolute power, corrupts absolutely!”

It appears that only Julius Caeser ever understood

100-44 BC
