1. I changed the title of this week’s update as a result of reading the study in A rejuvenation therapy and sulforaphane. The study wasn’t about sulforaphane, but its clinical findings had commonalities with this broccoli sprouts effort. It’s become the blog’s most popular post, read by people in 50+ countries.
A close second is An environmental signaling paradigm of aging. The study’s lead laboratory researcher presented his view five years ago on where aging evidence was pointing.
What are the effects that broccoli sprouts and their compounds may have on human aging? With this new human-rat relative biological age clock, researchers can get reliable answers from rat studies, with human clinical trials needed only to confirm those findings!
2. This week I found out that exercising control over my charges to protect them from disease was counterproductive. I exposed them to harm, destroyed their community, and stunted their growth by forcing them to distance from each other for their own good.
Am I a politician, an unelected bureaucrat, or some other form of busybody? No. I admit my mistakes right away, I apologize, then I immediately try to do better.
A proper context:
- In Week 2 I switched from sprouting trays with 1/16″ high ridges in the bottom to Russian-doll bowls. That solved a problem of excess moisture, with which broccoli sprouts don’t do well but bacteria do.
- In Week 3 I rotated in the next larger sized bowl to replace the smallest bowl. My thought was that Day 3 broccoli sprouts were too crowded to dry in the smallest bowl.
- At the end of Week 5 I doubled the starting amount of broccoli seeds from one to two tablespoons. To accommodate that increase, I again rotated in the next larger size bowl to replace the smallest bowl.
Starting in Week 6, I had uneven batch yields. The two larger bowls yielded noticeably fewer sprouts than did batches in the two smaller bowls.
What did bowl size have to do with yield? Nothing, it was me. It turned out I’d neglected Plant Care 101 instructions to provide adequate moisture.
After rinsing, straining, and wicking out excess moisture with a paper towel twice daily, I then spread out the seeds and sprouts to prevent problems with excess moisture. The broccoli seeds and sprouts in the two larger bowls were more separated than in the two smaller bowls.
All of which led to moisture levels that were inadequate for broccoli seeds and sprouts. All batches sprouted less well than their potential yield. The larger the bowl, the more my behavior adversely affected the batch.
Here’s what Day 2 and Day 3 yields were with my previous practices. The batch volume of Day 2 in the smaller bowl was larger than Day 3’s:
I changed practices to group broccoli seeds and sprouts together at the step where I used to spread them out. Here’s the same bowl with my current practice, but at Day 2. The photo may not show it well, but it’s a larger volume than the previous practice’s Day 2:
I’ll guess that batch yield volumes have improved by
60% 75%. I increased distilled water from 100 ml to 160 175 ml before microwaving since 100 ml no longer completely immersed the increased Day 3 broccoli sprout volume. My 1000W full power microwave time concomitantly increased from 45 seconds to 70 65 seconds to achieve 58°C.
The better-developed batches also taste better. I still mix in mustard and eat Day 3 broccoli sprouts with other food.
3. My sulforaphane intake has probably decreased with the current practice. The 3-day-old broccoli sprouts have the optimal yields study said:
“Although germination reduces SF [sulforaphane] yield to some extent, it is beneficial to the formation and accumulation of total phenol and flavonoids, ensuring the health properties of sprouts. SF contents in sprouts were 46% – 97% of seeds, whereas TP [total phenolic] and TF [total flavonoid] contents in sprouts were 1.12 – 3.58 times higher than seeds among [broccoli] varieties.”
I’m not concerned about less sulforaphane with a two tablespoons starting amount of broccoli seeds. Even a one tablespoon starting amount yields 60 g of broccoli sprouts, twice that of the model clinical trial, Effects of long-term consumption of broccoli sprouts on inflammatory markers in overweight subjects. See our discussion in Understanding a clinical trial’s broccoli sprout amount.
4. Another week of no inflammatory problems after four-to-six-mile-long beach walks. I’m not pushing myself, just walking often, and working out my upper body every fourth day.
I emphasize the eccentric motion in upper body workouts. I haven’t curated the below 2019 papers although they’re informative:
- https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6543991/ “Effect of Flywheel Resistance Training on Balance Performance in Older Adults. A Randomized Controlled Trial”
- https://www.mdpi.com/2411-5142/4/3/61/htm “Eccentric Overload Flywheel Training in Older Adults”
I don’t expect recovery times from workouts to shorten. What’s an appropriate exercise recovery time? found with 26.5 ± 6.5 year-old male subjects that even three days wasn’t enough time for the biceps brachii to fully recover from eccentric exercise.
5. During Friday’s walk I accidentally startled a large turkey hen who was on the ground, and she flew up on a fence. Can you see her moments before she hopped down to the other side?
Don’t have any idea what bugs a turkey found attractive near a beach.
