Part 2 of Do broccoli sprouts treat migraines?

To follow up Do broccoli sprouts treat migraines? which used a PubMed “sulforaphane migraine” search, a PubMed “diindolylmethane” search came across a 2020 Czech human cell study Antimigraine Drug Avitriptan Is a Ligand and Agonist of Human Aryl Hydrocarbon Receptor that Induces CYP1A1 in Hepatic and Intestinal Cells that had this informative Introduction:

“The aryl hydrocarbon receptor (AhR) transcriptionally controls a wide array of genes. AhR is a critical player in human physiology (e.g., hematopoiesis) and also in many pathophysiological processes such as diabetes, carcinogenesis, inflammation, infection or cardiovascular diseases.

Suitable candidates for off-targeting AhR could be the antimigraine drugs of triptan class, which have an indole core in their structure. Indole-based compounds were demonstrated as ligands of AhR, including dietary indoles (e.g., indole-3-carbinol and diindolylmethane).”

Adding AhR to the search showed:

Changing the PubMed search to “icz migraine” pulled up a 2013 review Biomedical Importance of Indoles that described sumatriptan as an indole, and:

“Since DIM accumulates in the cell nucleus, it likely contributes to cell nuclear events that have been ascribed to I3C.”

Widening the search to “i3c ahr” added:

Changing the search to “i3c migraine” picked up a 2011 UK human study Effect of diindolylmethane supplementation on low-grade cervical cytological abnormalities: double-blind, randomised, controlled trial:

“In the study reported here, there was no statistically significant difference in serious adverse events between groups; in fact a higher proportion of women in the placebo group reported a serious adverse event. Although this study did not have sufficient power to study migraines, we did find a non-significant increase in reported headaches (18% on DIM, 12% on placebo, P=0.12).”

Returning to the original PubMed “sulforaphane migraine” search, Bioavailability of Sulforaphane Following Ingestion of Glucoraphanin-Rich Broccoli Sprout and Seed Extracts with Active Myrosinase: A Pilot Study of the Effects of Proton Pump Inhibitor Administration included one subject who took migraine medication. They weren’t a study outlier, however.


Although indole chemistry indicates a broccoli sprouts – migraine connection, I haven’t found relevant research. Maybe the known properties and actions of broccoli sprout compounds provide enough to affect causes of migraines?

Eat broccoli sprouts for DIM

This 2019 Spanish human study ran in parallel with Our model clinical trial for Changing to a youthful phenotype with broccoli sprouts. I’ll focus on the aspect of diindolylmethane (DIM) from eating broccoli sprouts:

“The aim of this study is to evaluate the effect of gender or hormonal status (menopause) on the bioavailability of broccoli sprouts in different cohorts of overweight adult subjects: men, non-menopausal women and post-menopausal women.

3,3′-diindolylmethane (DIM) was detected and quantified in all volunteers. It increased significantly during broccoli [sprouts] ingestion in men. However, a steady decrease of its urinary concentration was observed in post-menopausal women that was significant at day 50. No significant changes were observed in premenopausal women. Albeit this different behaviour, no significant differences between the three groups were detected by the different statistical tests performed.

High increases observed in SFN-metabolites in the three cohorts confirm that the fresh product is a good source of bioactive compounds bioavailable in the organism. We detected high amounts of 3,3-DIM in urine samples, which can be related to the metabolism of glucobrassicin derivatives from our broccoli sprouts.

Post-menopausal women seem to metabolize isothiocyanates in a greater extension. Hormonal status and differences in gut microbiota may influence the bioavailability of isothiocyanates from broccoli sprouts but more studies are needed to support this statement.”

https://www.sciencedirect.com/science/article/abs/pii/S1756464619303147 “Bioavailability of broccoli sprouts in different human overweight populations” (not freely available)


“Post-menopausal women seem to metabolize isothiocyanates in a greater extension. A steady decrease of its [DIM] urinary concentration was observed in post-menopausal women that was significant at day 50.”

Subjects ate broccoli sprouts every day through Day 35, then stopped, and were measured again at Day 50. The only example of measurements where Day 35 was less than Day 0 was postmenopausal women retaining more broccoli sprout indolic compounds’ metabolite, DIM, than excreting it.

That Day 35 data point didn’t have an asterisk next to it to indicate a statistically significant decrease. But the group’s next Day 50 significant “steady decrease” finding supported an interpretation that eating broccoli sprouts supplied those overweight postmenopausal women with DIM that they especially needed.

Regarding the huge percentage changes above, our model clinical trial found in a longer time frame:

The decrease in IL-6 levels was significantly related to the increase in 24 h urine SFN [sulforaphane] levels. In case of C-reactive protein, the decrease was significantly related to the increases in 24 h urine SFN-NAC [SFN-N-acetylcysteine] and SFN-CYS [SFN-cysteine].

I’ll guess that these parallel trial subjects also experienced similar benefits from eating broccoli  sprouts every day for five weeks. See Day 70 results from Changing to a youthful phenotype with broccoli sprouts for another guess that even shorter time frames would be effective.


Broccoli sprout indolic compounds that metabolize to DIM:

Day 70 results from Changing to a youthful phenotype with broccoli sprouts

Here are my Day 70 measurements* to follow up Our model clinical trial for Changing to a youthful phenotype with broccoli sprouts, which had these findings:


Keep in mind that I’m not in the population represented by the clinical trial sample:

  1. My chronological age is above their inclusion range;
  2. My BMI is below their inclusion range; and
  3. I take supplements and meet other exclusion criteria.

I also didn’t take Day 0 measurements.

June 2019 BMI: 24.8

June 2020 BMI: 22.4

2020 IL-6: 1.0 pg / ml. See Part 2 of Rejuvenation therapy and sulforaphane for comparisons.

2020 C-reactive protein: < 1 mg / l.

2019 and 2020 No biological age measurements. Why aren’t epigenetic clocks standard and affordable?


I’ve made four lifestyle “interventions” since last summer:

  1. In July 2019 I started to reduce my consumption of advanced glycation end products after reading Dr. Vlassara’s AGE-Less Diet: How a Chemical in the Foods We Eat Promotes Disease, Obesity, and Aging and the Steps We Can Take to Stop It.
  2. In September I started non-prescription daily treatments of Vitamin D, zinc, and DHEA per clinical trial Reversal of aging and immunosenescent trends.
  3. Also in September, I started non-prescription intermittent quercetin treatments of Preliminary findings from a senolytics clinical trial.
  4. I started eating broccoli sprouts every day eleven weeks ago.

1. Broccoli sprouts oppose effects of advanced glycation end products (AGEs) provided examples of Items 1 and 4 interactions.

2. Two examples of Item 2 treatment interactions with Item 4 are in Reversal of aging and immunosenescent trends with sulforaphane:

  • “The effects of the combined treatment with BSE [broccoli sprout extract] and zinc were always greater than those of single treatments.”
  • “Vitamin D administration decreased tumor incidence and size, and the co-administration with SFN [sulforaphane] magnified the effects. The addition of SFN decreased the activity of histone deacetylase and increased autophagy.”

3. How broccoli sprout compounds may complement three supplements I take was in a 2020 review Central and Peripheral Metabolic Defects Contribute to the Pathogenesis of Alzheimer’s Disease: Targeting Mitochondria for Diagnosis and Prevention:

“The nutrients benefit mitochondria in four ways, by:

  • Ameliorating oxidative stress, for example, lipoic acid;
  • Activating phase II enzymes that improve antioxidant defenses, for example, sulforaphane;
  • Enhancing mitochondrial remodeling, for example, acetyl-l-carnitine; and
  • Protecting mitochondrial enzymes and/or stimulating mitochondrial enzyme activities, for example, enzyme cofactors, such as B vitamins and coenzyme Q10 .

In addition to using mitochondrial nutrients individually, the combined use of mitochondrial nutrients may provide a better strategy for mitochondrial protection.”

The review provided a boatload of mitochondrial multifactorial analyses for Alzheimer’s. But these analyses didn’t include effective mitochondrial treatments of ultimate aging causes. I didn’t see evidence of why, after fifteen years of treating mitochondrial effects with supplements, treating one more effect could account for my Week 9 vastly different experiences.


I nod to An environmental signaling paradigm of aging explanations. Its Section 10 reviewed IL-6, C-reactive protein, senescence, and NF-κB in terms of feedback loops, beginning with:

“It is clear that the increasing number of senescent cells depends on the post-adult developmental stage rather than chronological age. The coincidence that these processes result in particular forms of impairment in old age does not seem to be random as it is present in all mammals, and may be causative of many aspects of aging.”

A derived hypothesis: After sufficient strength and duration, broccoli sprout compounds changed my signaling environment, with appreciable effects beginning in Week 9.

I offered weak supporting evidence in Upgrade your brain’s switchboard with broccoli sprouts where a study’s insufficient one week duration of an insufficient daily 17.3 mg sulforaphane dosage still managed to change a blood antioxidant that may have changed four thalamus-brain-area metabolites. For duration and weight comparisons, I doubled my daily amount of broccoli seeds from one to two tablespoons just before Week 6 (Day 35), and from that point onward consumed a worst-case estimated 30 mg sulforaphane with microwaving 3-day-old broccoli sprouts every day.

Maybe a promised “In a submitted study, we will report that peripheral GSH levels may be correlated with cognitive functions” will provide stronger evidence? I’m not holding my breath for relevant studies because:

  • There wouldn’t be potential payoffs for companies to study any broccoli sprout compound connections with research areas such as aging, migraines, etc. Daily clinically-relevant broccoli sprout dosages can be grown for < $500 a year.
  • Sponsors would have to change paradigms, a very-low-probability event. They’d have to explain why enormous resources dedicated to current frameworks haven’t produced effective long-term treatments.

What long-term benefits could be expected if I continue eating broccoli sprouts every day?

The longest relevant clinical trial I’ve seen – referenced in Part 2 of Reversal of aging and immunosenescent trends with sulforaphane – was twelve weeks. Part 2 also provided epigenetic clock examples of changes measured after 9 months, which accelerated from there to the 12-month end-of-trial point.

Reviewing clinical trials of broccoli sprouts and their compounds pointed out:

“Biomarkers of effect need more time than biomarkers of exposure to be influenced by dietary treatment.”


A contrary argument: Perhaps people don’t require long durations to effectively change their signaling environments?

I apparently didn’t start eating an effective-for-me daily broccoli sprouts dosage until Day 35, when I changed from one to two tablespoons of broccoli seeds a day. If so, Weeks 6 through 8 may account for my substantial responses during Week 9.

Could eating broccoli sprouts every day for four weeks dramatically change a person’s signaling environment?

Do you have four weeks and $38 to find out? Two tablespoons of broccoli seeds = 38 g x 30 days = 1.14 kg or 2.5 lbs.

This is what twice-a-day one-tablespoon starting amounts of broccoli seeds look like through three days:


Maintaining the sprouting process hasn’t been a big effort compared with the benefits.

In the absence of determinative evidence, I’ll continue eating broccoli sprouts every day. Several areas of my annual physical have room for improvements. Extending my four lifestyle “interventions” a few more months may also provide hints toward inadequately researched connections.

* Results may not be extrapolatable to other people, to any specific condition, etc.

Week 10 of Changing to a youthful phenotype with broccoli sprouts

To follow up Week 9 of Changing to a youthful phenotype with broccoli sprouts:

1. I increased three of eight upper body exercises by 50% through adding another set. I did it because I didn’t feel muscle exhaustion after two sets like I’d previously felt. 🙂

Cognitively, see A claim of improved cognitive function and its follow on Upgrade your brain’s switchboard with broccoli sprouts.

2. It’s been inspirational at times, and at other times, dull, duller, dullest, to do what’s necessary and keep on track. But the efforts paid off when Week 9 was unlike any previous week!

I expressed appreciation in Our model clinical trial for Changing to a youthful phenotype with broccoli sprouts because scientific evidence provides great bases for intentional behavior. It’s still up to me to voluntarily carry out my part. And why wouldn’t I act when my healthspan and lifespan are the consequences? Except…

What if I’d been:

  • Tired of the hassle, or bored with self-imposed discipline, or lazy, and quit?
  • Projecting personal problems onto others, such that improving my present and future became less important than act-outs?
  • Distracted by, or believed propaganda, or participated in Madness of Crowds behavioral contagion, and missed day after day of required actions?

I may not have ever experienced Week 9’s intermediate-term benefits!

If I keep going past ten weeks, what long-term benefits could be expected?

Our model clinical trial didn’t say how researchers decided on a ten-week period for subjects to consume broccoli sprouts every day. I asked a study coauthor about trial duration, but no answer yet.

A few of the same coauthors answered generally in Reviewing clinical trials of broccoli sprouts and their compounds:

Biomarkers of effect are early stage end-points, for instance the modulation of phase 2 enzymes by glucosinolates. They need more time than biomarkers of exposure to be influenced by the dietary treatment.

Hence, length or duration of the study must be defined according to the biomarker measured to be modified, that is, to define perfectly the time of exposure to observe changes in relevant parameters. Gene expression is one important target for glucosinolates, and it requires a sufficient period of exposure to (de)activate signaling pathways involved.

It is crucial to find appropriate biomarkers of effect that are linked to later disease outcomes, and more investigation is needed in this sense. Post-study follow-up can be of great value in assessing the persistence of certain effects, or in discovering those that appear more long-term.

3. I’ll go into a clinic on Sunday for Day 70 truth tests. Here they are: Day 70 results from Changing to a youthful phenotype with broccoli sprouts!

Our model clinical trial for Changing to a youthful phenotype with broccoli sprouts

The further I get into a daily regimen of eating broccoli sprouts for ten weeks, the more I appreciate “Effects of long-term consumption of broccoli sprouts on inflammatory markers in overweight subjects.”

“This study represents an advance in intervention studies as the broccoli sprouts were included in a daily dietary pattern in quantities that reflect a real consumption. The hypothesis of our research is that broccoli sprouts are able to reduce the inflammatory status in overweight subjects due to their content in phytochemicals, mainly glucosinolates.

Total concentration of aliphatic glucosinolates was 80.50 mg/30 gf.w. This concentration was two-fold higher than indolic glucosinolates. Volunteers consumed an average of 51 mg (117 μmol) and 20 mg (42 μmol) of glucoraphanin and neoglucobrassicin, respectively, on a daily basis, during the 70 days of the dietary intervention. Considering an amount of GRA [glucoraphanin] of 117 μmol by serving, a 4% on average was metabolized through mercapturic acid pathway.

No significant changes were observed in weight and BMI. By contrast, body fat mass slightly decreased significantly after 70 days of broccoli [sprout] consumption and returned to basal levels at day 90, a state that was maintained until day 160.

The decrease in IL-6 levels was significantly related to the increase in 24 h urine SFN [sulforaphane] levels. In case of C-reactive protein, the decrease was significantly related to the increases in 24 h urine SFN-NAC [SFN-N-acetylcysteine] and SFN-CYS [SFN-cysteine].

The possible synergistic interaction of both SFN and 3,30-DIM and the isothiocyanates erucin and sulforaphane are interconvertible, so that the anti-inflammatory effects observed with broccoli sprouts intake are likely due to the combined effects of all the hydrolysis products of glucosinolates.

Modifications I’ve made to the clinical trial’s protocols include:

  1. I start new broccoli sprout batches twice a day with one tablespoon of seeds per A pair of broccoli sprout studies.
  2. Per 3-day-old broccoli sprouts have the optimal yields, I consume broccoli sprouts when they’re 3 days old. The clinical trial subjects ate broccoli sprouts that were at least a week old.
  3. I immerse 3-day-old broccoli sprouts in 100 ml distilled water, then microwave them on 1000W full power for 35 seconds to achieve up to but not exceeding 60°C (140°F) per Microwave broccoli to increase sulforaphane levels.
  4. Per Enhancing sulforaphane content, after microwaving I transfer broccoli sprouts to a strainer, and allow further myrosinase hydrolization of glucoraphanin and other glucosinolates into sulforaphane and other healthy compounds.

I use the above studies as guides to create broccoli sprout hydrolysis compounds just before eating them. I don’t depend on my metabolism to create sulforaphane, DIM, erucin, and other hydrolysis compounds as did the clinical trial. But then again, those subjects ate super sprouts:

“We used the elicitor methyl jasmonate (MeJA) by priming the seeds as well as by spraying daily over the cotyledons from day 4-7 of germination. We observed that MeJA at concentrations of 250 μmol act as stressor in the plant and enhances the biosynthesis of the phytochemicals glucosinolates.

Compared to control plants without MeJA treatment, the content of compounds as the aliphatic glucosinolate glucoraphanin was enhanced up to a 70% and similar increases were observed with glucoiberin or glucobrassicin. In this way, we improved the content of these health-promoting compounds.”

I don’t have a scale in my kitchen, and don’t have a measured weight of broccoli sprouts consumed daily. It’s probably more than twice the clinical trial’s 30 grams:

  • My most recent broccoli seed purchase was a 5 pound can (2,268 grams). Its volume by the formula height x π x (diameter / 2)2 with 17 cm height and 15 cm diameter is 1,767 cubic centimeters.
  • With 1 tablespoon = 14.79 cc, (14.79 cc / 1,767 cc) x 2,268 grams = 19 grams per serving. Broccoli seed weight of two servings is 19 x 2 = 38 grams a day.
  • The lowest weight gain for 3-day-old broccoli sprouts in Item 2 above was 4.32 times the seed weight. That was in laboratory conditions, though.
  • Let’s guess that 3-day-old broccoli sprouts only gain twice as much weight in my kitchen, 38 g x 2 = 76 grams. A comparable worst-case Estimating daily consumption of broccoli sprout compounds calculation was 75.52 grams.

Upgrade your brain’s switchboard with broccoli sprouts

Further investigating A claim of improved cognitive function, Part 3 of Rejuvenation therapy and sulforaphane offered:

“Improving brain function does not depend on neurogenesis as much as it does on synapse formation and factors such as NMDA receptors which decline in density with age.”

A PubMed “sulforaphane NMDA receptors” search turned up a 2019 cell study The glutathione cycle shapes synaptic glutamate activity:

Sulforaphane is a potent inducer of the Nrf2 transcription factor, has blood–brain barrier penetration, and might expand the size of the glutathione reservoir by our observation that it increases expression of GCL [glutamate cysteine ligase], the rate-limiting step in glutathione biogenesis. Our recent study in human subjects revealed that sulforaphane elevates peripheral glutathione levels and those of other brain metabolites.”

The referenced study was a 2017 Sulforaphane Augments Glutathione and Influences Brain Metabolites in Human Subjects: A Clinical Pilot Study:

“We found that the naturally occurring isothiocyanate sulforaphane increased blood GSH [reduced glutathione] levels in healthy human subjects following 7 days of daily oral administration. In parallel, we explored the potential influence of sulforaphane on brain GSH levels in the anterior cingulate cortex, hippocampus, and thalamus via 7-T magnetic resonance spectroscopy.

A significant positive correlation between blood and thalamic GSH post- and pre-sulforaphane treatment ratios was observed, in addition to a consistent increase in brain GSH levels in response to treatment. The sulforaphane response in brain GSH levels is not influenced by age, sex, or race.

The participants were given 100 µmol sulforaphane as standardized broccoli sprout extract in the form of 2 gel capsules, and instructed to ingest the extract each morning for 1 week.

Following sulforaphane administration, the increase in blood GSH was positively correlated with GABA, Gln [glutamine], Glu [glutamate], and GSH in the THAL [thalamus]. Although these correlations were not significant following multiple comparison, they remain suggestive. Power analysis calculations suggest that a sample size of n = 50 would yield a significant result, and this will be the focus of a future study.

As has been reported for cardiovascular and cerebrovascular diseases, longer treatment duration and/or higher dosages may be warranted. In a submitted study, we will report that peripheral GSH levels may be correlated with cognitive functions.”


One week of consuming sulforaphane wasn’t long enough to achieve much. Not enough subjects and “higher dosages may be warranted” were also thrown in to explain the lack of significant results.

Sulforaphane: Its “Coming of Age” as a Clinically Relevant Nutraceutical in the Prevention and Treatment of Chronic Disease estimated the “100 µmol sulforaphane” dosage to be 17.3 mg. Worst-case estimates made in Estimating daily consumption of broccoli sprout compounds are that since doubling the starting amount of broccoli seeds from one to two tablespoons in Week 6, I’ve consumed 30 mg sulforaphane with microwaving 3-day-old broccoli sprouts every day.

Something happened where the promised “In a submitted study, we will report that peripheral GSH levels may be correlated with cognitive functions” either wasn’t performed or wasn’t published. The follow-on 2019 study became a cell study instead of a 50+ person study.


The study’s thalamus findings provided plausible explanations for why eating a clinically relevant amount of broccoli sprouts every day since at least Week 6, Week 9 was so much different from the others. Sulforaphane changed a blood antioxidant which may have changed four thalamus metabolites.

The thalamus part of our brain is analogous to a switchboard. Signals pass through it to and from other brain areas.

Signals can be routed better when we clean up and upgrade wiring, and lower circuit resistance.

A claim of improved cognitive function

I’ll describe evidence for claiming improved cognitive function in Week 9 of Changing to a youthful phenotype with broccoli sprouts.

I read parts of over a hundred research papers last week. That required substantial concentration to understand them, and stay on topic while learning new items, which started new searches. This wasn’t a new development, it was just to a much greater extent. I also worked forty hours for my job.

The main chain of blog posts began when I relooked at the presentation in Reversal of aging and immunosenescent trends after remembering it included before and after photos per A hair color anecdote. The presentation prompted last week’s most frequent self-question, Why didn’t I see this before?

One possible explanation is that people don’t usually see things outside their conditioned perceptions. (1) Reevaluate findings in another paradigm illustrated this with an example of how different frameworks viewed the same hypothalamus study differently.

I was interested to see what sulforaphane research had in common with the presentation topics, which produced (2) Reversal of aging and immunosenescent trends with sulforaphane. That required gaining a better understanding of PubMed search techniques, which led to (3) A pair of broccoli sprout studies.

Numerous presentation topics resulted in (4) Part 2 of Reversal of aging and immunosenescent trends with sulforaphane. I investigated one of its cited papers in (5) A review of sulforaphane and aging, which required further searches, some of which are still on tabs of my browser.

I was happy to oblige special requests with (6) Tailoring measurements for broccoli sprouts and (7) Uses of the lymphocytes to monocytes ratio.

Could I have done all of what I did last week without changing my internal environment? What exactly are the effects of eating a clinically relevant amount of broccoli sprouts every day for nine weeks?

A plausible explanation is in Upgrade your brain’s switchboard with broccoli sprouts.

Week 9 of Changing to a youthful phenotype with broccoli sprouts

To follow up Week 8 of Changing to a youthful phenotype with broccoli sprouts:

1. This week has really been different.

A. Physically, on Friday Eve I worked out per my usual upper-body-workout-every four-days routine. I felt strong, and on one exercise I increased the weight by 33%. No problem doing the same number of reps and sets! Keeping good form was challenging.

Per Week 7, I eight-count each concentric rep slowly, then perform each eccentric rep to the same count, with a goal to reach muscle exhaustion during each set. Then pause and do another set.

What changed? Could I have done all this before?

No. I’d tried, making baby steps with increasing weight and keeping good form. But now I can, and I’ll do it again, along with other physical challenges.

B. Seven of this week’s blog posts may be evidence of improved cognitive function. Awakening was how it felt.

Is A claim of improved cognitive function sufficient evidence?

C. This 35th blog post for May comes after 30 posts in April. It wasn’t my goal to do one a day. It’s my goal to Surface Your Real Self. Did a few of them help?

I hope to do other things with my life in June. But the fact remains that humans are herd animals. We “think in herds, go mad in herds, while they [we] only recover their [our] senses slowly, one by one.” We’ll stay in the Madness of Crowds phase until enough people refuse to be propagandized.

2. As a result of reading A pair of broccoli sprout studies, I changed practices to start batches with one tablespoon of broccoli seeds twice a day so I could consume broccoli sprouts twice daily. Right now it’s a PITA task that requires optimization.

The two studies’ findings were:

  1. Broccoli sprouts are better than supplements.
  2. Eating sprouts twice a day is better than eating them once a day.
  3. When in doubt, refer back to Item 1.

3. I reordered broccoli seeds and will receive them next week. In the meantime, I introduced yet another unknown by consuming sprouts that came from a different vendor:

These seeds are smaller. Hundreds of seeds and seed coats annoyingly pass through my strainer, which didn’t happen with larger seeds. 3-day-old sprout sizes are smaller, and they smell and taste different.

Worst-case estimates made in Estimating daily consumption of broccoli sprout compounds would be higher with a smaller seed size. If I recalculated, though, they wouldn’t be worst cases anymore. So I’ll leave them at 21 mg sulforaphane without microwaving and 30 mg sulforaphane with microwaving from eating 3-day-old broccoli sprouts every day.

This vendor put “seed” four times on their label. The other vendor didn’t bother to put “seed” even once on their broccoli seed package label.

Like other vendors, they prefer buzzword marketing with “microgreen” and “sprouting” rather than provide useful consumer information such as number of seeds and broccoli variety characteristics. Will people buy “Broccoli Sprouting Seeds” but won’t buy Broccoli Seeds? Do people say “Cool beans!” anymore?

My reorder states there are ~720,000 broccoli seeds in that 5 lb. package. I’ll update with its volume after it arrives.

See Week 10 of Changing to a youthful phenotype with broccoli sprouts for follow ups.

Uses of the lymphocytes to monocytes ratio

To follow up a presentation topic of Part 2 of Reversal of aging and immunosenescent trends with sulforaphane, here are a few papers no earlier than 2015 that address the ratio of lymphocytes to monocytes (LMR), or its reciprocal MLR. Because inquiring minds want to know. 🙂

  1. Monocyte heterogeneity and functions in cancer

    “The ratio of lymphocytes to monocytes has emerged as a prognostic factor, including for B cell lymphoma, colorectal cancer, lung cancer, and ovarian cancer. For example, in patients with stage III colon cancer, a higher lymphocyte to monocyte ratio was associated with increased time to recurrence and overall survival.”

  2. Distinct Transcriptional and Anti-Mycobacterial Profiles of Peripheral Blood Monocytes Dependent on the Ratio of Monocytes: Lymphocytes

    “Our observation of monocyte functional and transcriptional differences dependent on the ML ratio (but on neither constituent alone) suggests that qualitative differences in monocytes are better reflected by the ML ratio than by monocyte counts alone, potentially explaining epidemiologic associations of the ratio. The ML ratio was associated with mycobacterial growth in vitro (β = 2.23, SE 0.91, p = 0.02). The significant enrichment of interferon signalling we found supports a common role for type I and II interferons in altering the ML ratio and monocyte function sufficiently to explain altered disease course, consistent with the central role of interferons in mycobacterial and inflammatory diseases. In humans, myeloid-biased HSC accumulate with age and explain the relative increase in myeloid cells in blood with age. Therefore changes in ML ratio in blood are likely a marker of changes in the frequency of lineage-biased HSC.”

  3. Monocyte–lymphocyte ratio is a valuable predictor for diabetic nephropathy in patients with type 2 diabetes

    “T2D patients without diabetic-related complications had higher MLR than control patients. MLR was significantly higher in DN patients than in T2D patients without diabetic-related complications.”

  4. Monocyte lymphocyte ratio predicts the new-onset of chronic kidney disease: A cohort study

    “Increased baseline MLR is strongly associated with the risk of new-onset CKD in people with normal or near-normal kidney function at baseline. Inflammatory markers such as interleukin are difficult to be measured by primary medical care. Therefore, search for simpler inflammatory markers to predict the risk of CKD. MLR represent[s] the state of balance between inflammatory activators and inflammatory regulators. The higher the ratio, the greater the imbalance, the more severe the inflammatory response and the stronger the immune suppression. In addition to increasing the risk of new-onset CKD, our study found MLR was positively related to inflammatory factors, such as leukocytes, neutrophils, NLR, PLR and platelet distribution width. In addition, MLR was positively correlated with age, blood pressure and BMI. However, there was no significant correlation between MLR and fasting plasma glucose in non-diabetic participants. A total of 11280 participants (6592 male and 4688 female) were enrolled in this longitudinal study.”


A LMR of 5 and a MLR of 0.2 are easy-to-measure heuristics, adequate for screening people. These ratios can be used along with many other measurements as starting points to investigate underlying causes.

Item 1 described how LMR also has prognostic value for cancers. The other studies used MLR as a biomarker for the future course of inflammatory diseases per:

“The higher the ratio, the greater the imbalance, the more severe the inflammatory response and the stronger the immune suppression.”


I’d seen the below presentation graphic several times since September 2019. My reaction was “Oh, that’s interesting” each time.

On Friday I understood it: This was what resetting your internal environment looked like.

Did my paradigm change? Yes, among other things, and all of that allowed me to see.

An environmental signaling paradigm of aging provided evidence up through 2015 for its hypothesis and framework. Its treatments’ capabilities to:

“Reset to different age-phenotypes

will be tested as the 2020 study underlying A rejuvenation therapy and sulforaphane is tested.

Caution is warranted before getting carried away with ratio analyses of a 9-subject pilot study. Are hormone ratios useful in explaining health? Behavior? Neurobiology? Anything? recommended:

“Analysis of the individual variables offers more information and a more accurate picture of the underlying relationships.

Ratios should either be analyzed with non-parametric techniques, or be log-transformed before parametric statistical methods are applied.”

There was monocyte but not lymphocyte data in the clinical trial’s supplementary material.

A review of sulforaphane and aging

This 2019 Mexican review stated:

“We describe some of the molecular and physical characteristics of SFN, its mechanisms of action, and the effects that SFN treatment induces in order to discuss its relevance as a ‘miraculous’ drug to prevent aging and neurodegeneration. SFN has been shown to modulate several cellular pathways in order to activate diverse protective responses, which might allow avoiding cancer and neurodegeneration as well as improving cellular lifespan and health span.

NF-κB is in charge of inflammatory response regulation. Under basal conditions, NF-κB is sequestrated into the cytosol by IκB, but when pro-inflammatory ligands bind to its receptors, the IKK protein family phosphorylates IκB to degrade it via proteasome, so NF-κB is able to translocate into the nucleus and transcript several inflammatory mediators. Sulforaphane is capable to inhibit IκB phosphorylation and NF-κB nuclear translocation.

SFN upregulated Nrf2 expression by reducing DNA demethylation levels of the Nrf2 promoter. In another model using the triple-transgenic mouse model of Alzheimer’s disease (3 × Tg-AD), the use of SFN regulates the expression of the Brain-derived neurotrophic factor (BDNF) via HDAC inhibition, thus increasing H3 and H4 acetylation on the BDNF promoter. Enhancing BDNF expression as an effect of SFN treatment increased the neuronal content of several synaptic molecules like MAP 2, synaptophysin, and PSD-95 in primary cortical neurons of 3 × Tg-AD.”

I came across this review while searching PubMed for sulforaphane commonalities with presentation topics in Part 2 of Reversal of aging and immunosenescent trends with sulforaphane. The review outlined some aging aspects and presented relevant sulforaphane studies. Others such as eye and muscle decline weren’t addressed.

Since sulforaphane’s “a ‘miraculous’ drug” in the Abstract, I expected but didn’t see corresponding excitement in the review body. Just phrases like “it is known” and non-specific “more research is needed.”

Other papers published after this review were found by a PubMed “sulforaphane signal aging” search:
