    Haven't been sick at all since taking Zinc

    Welcome Marco! Sorry for the mix up. Your question was fine. Forgive us for our suspicion but being an open forum we get many people who come here for the first time who have less than noble intentions for posting, often trying to get people to click on their link or buy their product to receive a commission. Now that we know you are a real person with sincere questions you are more than welcome to post them. You might be especially interested in this thread devoted to prostate cancer prevention. You might also want to check out the section of nutritionfacts.org on prostate health. --Dean

    It looks like garlic may be a good way to counteract too much dietary lead: https://nutritionfacts.org/2020/09/10/garlic-powder-to-lower-lead-levels/ --Dean

    Haven't been sick at all since taking Zinc

    FWIW, the first time a new person posts their post is held for approval by an admin. I saw Marco's post a couple of days ago and I too thought it seemed a little spammy, although most true spam posts include a link which this one didn't. So I didn't approve it but I didn't delete it either (like I sometimes do with obvious spam), leaving it in limbo. Someone else with admin privileges must have judged it to be legit enough to approve it. I'm not sure who, since I don't know who else who regularly reads this forum has admin privilege. Let's see if Marco responds to your reasonable suggestion of taking zinc and saw palmetto individually rather than buying the more expensive combination of the two. --Dean

    Natto is the way to go!

    I moved my response to Tom's question above my garden to the CR Garden thread. --Dean

    A CR Garden

    Yes! I've got my usual vegetable garden this year with most of the things I grow every year, detailed here. My pawpaw trees have done even better than last year. I expect to harvest about 60 good-sized pawpaws in about 3 weeks. This spring I also planted three more pawpaw trees in my backyard which I started three years ago from seed and which are now about 3ft tall. The one new item I've grown this year are cape gooseberries, after really enjoying them when we vacationed in Costa Rica in January, just before covid hit. They are easy to grown and taste amazing - like a mildly tart grape. Seeds are available for $1.99 on ebay. --Dean

    Natto is the way to go!

    I'm back here to report on my natto culturing experiment. I regularly buy dried soybeans from nuts.com, although you can get them cheaper (i.e. $0.02/oz) on Amazon. Since they double in weight when cooked, that is about 2 cents worth of soybeans for the equivalent of a 50g styrofoam container of natto. Obviously the key ingredient is the natto spores. I bought 10g worth of spores for ~$3.25 on ebay. They took about 3 weeks to arrive (from China), hence the delay in my update. As can be seen below, the spores come in 10 1-gram sleeves, which is really nice since it doesn't take much spore to culture a batch. The soybeans cook like other dried beans, taking about 1.5 hours on a low simmer until they are softened. Like the other legumes I eat, I cook a big batch and freeze them in individual 500g freezer bags for later combination into my starch mix. To make my first batch of natto, I took ~50g of frozen soybeans and thawed them in the microwave for about a minute. Then I spread them into a thin layer in a rectangular (6"x2.5") glass dish, as shown here: I then brought about 2 tsp of water to a boil and then poured about 1/4 of the contents of one of the 1-gram sleeves of natto spores into the water, stirring until the spores dissolve. As I said, it doesn't take much. Even that much of the spores was probably overkill for the amount of natto I was making. Then I poured the spore water over the beans, stirred them around to make sure they were all moistened and then flattened the beans again in the glass dish. Then I covered the dish with a sheet of plastic wrap with a few holes poked in it: Next I put the dish on top of the metal disk shown above, which I in turn placed on top of a Salton mug warmer I've had for many years, shown below: I determined through a little experimentation that the metal disk acts as enough of a heat sink for the cup warmer so as to keep the glass disk on top at ~105degF, which is close to the optimal temperature for culturing natto. I then covered the dish with a clean dish towel, as shown below and left it to ferment: 24 hours later, it worked! Here is end result, nice and slimy natto. 🙂 I then stored the natto in the fridge overnight before eating (as recommended in these instructions). I'm happy to report it tastes and smells like the store-bought natto. Next time I'll probably scale up to make 100g at a time using a dinner plate rather than the glass dish to hold more beans. Eating ~25g/day, I estimate these supplied should last months and cost a couple pennies per serving. --Dean

    "Extreme" Exercise - Good or Bad?

    I wore a Fitbit Charge 2 for a couple of years (see my review here). Since my lifestyle is so regular, I found that I stopped learning anything useful from all the repetitive data. Also I found that I can become obsessed with the numbers and milestones, which I find not psychologically healthy or pleasant. It is the same reason that I don't weigh my food or meticulously count calories anymore. --Dean
  8. Tom will appreciate this article, which pretty much sums up Neurolink and Musk's general modus operandi. It is titled "I was excited for Neuralink. Then I watched Elon Musk’s stupid demo". Here is an excerpt: Musk makes promises first, then expects someone he pays to come up with the science to make it work. Neuralink is purported to eventually be capable of curing spinal injuries, autistic spectrum disorder, neurological disorders, anxiety, depression, pain, unhappiness, and letting you control any gadget with your mind. Most of this is pie-in-the-sky nonsense that we could be centuries away from pulling off and some of it is just flat out nonsense that medical professionals scoff at as absurd (you can’t, for example, cure autistic spectrum disorder because it isn’t a disease). But that didn’t stop me from getting hyped up to the point of forgetting that Musk is a con-artist at worst and just some dude with a bunch of money and charisma at best. Read the article for a full assessment of how little (new) the latest demo actually demonstrated. --Dean

    "Extreme" Exercise - Good or Bad?

    Thanks Al, Pick away! You are probably thinking of the episode described in this post from fall 2017 where I reported dialing back my exercise to 1 mile of running, 30 min of resistance training, 60 min of stationary biking and 3 miles of walking due to pain in my knees. As I mentioned in this post, I thought at the time I was just getting older and my many years of copious exercise had finally caught up with me. But the pain only got worse, until I thought to get tested for the above-mentioned Lyme disease. (I'd spent much of the summer of 2017 living in the forest, so I should have realized the possibility of Lyme disease sooner). Thankfully, after a month-long course of antibiotics and another month or two of taking it easy by my usual exercise standards the joint pain went away and I was good as new and back to my usual exercise routine. The best thing to come out of that painful episode was the "arm pocket" mattress idea (described here) to take the pressure off my shoulders which were also quite sore from the Lyme disease. To this day I sleep more comfortably than I ever have before using that method. --Dean

    "Extreme" Exercise - Good or Bad?

    Thanks Tom, I quote the most-relevant two sentences from the exercise study you posted: Finally, there is no evidence for an upper limit of exercise-induced health benefits. Every volume of moderate- and vigorous-intensity aerobic exercise results in a reduction of all-cause and CVD mortality compared with physical inactivity. Regarding the "sweet spot" for the amount of walking exercise - there is this 2020 study [1] in JAMA (which I posted before on the Walking and All Cause Mortality thread). It found that walking 8000 steps per day was associated with a ~50% reduction in all-cause mortality relative to 4000 steps per day. Boosting steps to 12,000 per day appeared to be even better. It was associated with a 65% reduction in all-cause mortality even after adjusting for the following potential confounders: sex, age, diet quality, race/ethnicity, body mass index, education, alcohol consumption, smoking status, diabetes, stroke, coronary heart disease, heart failure, cancer, chronic bronchitis, emphysema, mobility limitation, and self-reported general health. Interestingly, walking intensity (i.e. steps per minute) didn't seem to matter much at all. Obviously 12K steps (~5 miles) is a lot less than the ~45K steps (~20 miles) walking per day that I do. And despite adjusting for potential confounders, there is always the possibility of reverses causality in this kind of observational study - i.e. people less likely to die (for reasons other than walking) may tend to walk more. But at least there doesn't seem to be evidence for a ceiling on the benefits of walking, especially (presumably) if coupled with other healthy habits of diet, sleep, stress management, not smoking, etc. -Dean ----------- [1] JAMA. 2020;323(12):1151–1160. doi:10.1001/jama.2020.1382 Association of Daily Step Count and Step Intensity With Mortality Among US Adults. Saint-Maurice PF, Troiano RP, Bassett DR, et al. Abstract Importance It is unclear whether the number of steps per day and the intensity of stepping are associated with lower mortality. Objective Describe the dose-response relationship between step count and intensity and mortality. Design, Setting, and Participants Representative sample of US adults aged at least 40 years in the National Health and Nutrition Examination Survey who wore an accelerometer for up to 7 days ( from 2003-2006). Mortality was ascertained through December 2015. Exposures Accelerometer-measured number of steps per day and 3 step intensity measures (extended bout cadence, peak 30-minute cadence, and peak 1-minute cadence [steps/min]). Accelerometer data were based on measurements obtained during a 7-day period at baseline. Main Outcomes and Measures The primary outcome was all-cause mortality. Secondary outcomes were cardiovascular disease (CVD) and cancer mortality. Hazard ratios (HRs), mortality rates, and 95% CIs were estimated using cubic splines and quartile classifications adjusting for age; sex; race/ethnicity; education; diet; smoking status; body mass index; self-reported health; mobility limitations; and diagnoses of diabetes, stroke, heart disease, heart failure, cancer, chronic bronchitis, and emphysema. Results A total of 4840 participants (mean age, 56.8 years; 2435 [54%] women; 1732 [36%] individuals with obesity) wore accelerometers for a mean of 5.7 days for a mean of 14.4 hours per day. The mean number of steps per day was 9124. There were 1165 deaths over a mean 10.1 years of follow-up, including 406 CVD and 283 cancer deaths. The unadjusted incidence density for all-cause mortality was 76.7 per 1000 person-years (419 deaths) for the 655 individuals who took less than 4000 steps per day; 21.4 per 1000 person-years (488 deaths) for the 1727 individuals who took 4000 to 7999 steps per day; 6.9 per 1000 person-years (176 deaths) for the 1539 individuals who took 8000 to 11 999 steps per day; and 4.8 per 1000 person-years (82 deaths) for the 919 individuals who took at least 12 000 steps per day. Compared with taking 4000 steps per day, taking 8000 steps per day was associated with significantly lower all-cause mortality (HR, 0.49 [95% CI, 0.44-0.55]), as was taking 12 000 steps per day (HR, 0.35 [95% CI, 0.28-0.45]). Unadjusted incidence density for all-cause mortality by peak 30 cadence was 32.9 per 1000 person-years (406 deaths) for the 1080 individuals who took 18.5 to 56.0 steps per minute; 12.6 per 1000 person-years (207 deaths) for the 1153 individuals who took 56.1 to 69.2 steps per minute; 6.8 per 1000 person-years (124 deaths) for the 1074 individuals who took 69.3 to 82.8 steps per minute; and 5.3 per 1000 person-years (108 deaths) for the 1037 individuals who took 82.9 to 149.5 steps per minute. Greater step intensity was not significantly associated with lower mortality after adjustment for total steps per day (eg, highest vs lowest quartile of peak 30 cadence: HR, 0.90 [95% CI, 0.65-1.27]; P value for trend = .34). Conclusions and Relevance Based on a representative sample of US adults, a greater number of daily steps was significantly associated with lower all-cause mortality. There was no significant association between step intensity and mortality after adjusting for total steps per day.

    We got off topic discussing "extreme" exercise, mostly my fault. I started a new thread on the topic and moved the last 15 posts over there. Sorry for the inconvenience. --Dean

    "Extreme" Exercise - Good or Bad?

    Mike, As I've said many times before, I'm not one to shy away from informed and informative extremism for the reasons I listed in that 2016 post, but which can be summarized as "it is better to live a life less ordinary than a lifeless ordinary." Only time will tell if my lifestyle should be considered a shining example or a dire warning. Sadly, I know all too well that cancer is a crapshoot and can strike anyone at any age. But so far so good. All my health indicators seem good, including BP which is supposed to be the topic of [the original] thread. And for what it is worth, I haven't had an illness or injury (besides a bout of Lyme disease) in well over a decade, not even a cold. So it would seem I've been doing something right. Your mileage may vary. --Dean

    "Extreme" Exercise - Good or Bad?

    During the first two higher-intensity stints I'm mostly reading the news so it doesn't require a very high level of concentration. I do more cerebral reading at 3 mph, which seems pretty easy to manage. --Dean
