The problem here is that many people are confused as to what constitutes a good diet vs a bad diet . Personally I would avoid any type of regimented and strict diets which are based on prohibiton and forbiding and excluding certain foods. ..Everything in moderation together with regular exercise seems to work well for most people..There are no magical superfoods or diets.

Folks who are interested in performance in any athletic endeavor certainly have to be cognizant of the effect diet has on performance. The effect of exercise on longevity is well documented. The effect of diet on longevity, not so much. But longevity and the causative effect of athletic performance also may not be well documented.

Thanks, that's very interesting. My diet is a work in progress. I just try to keep away from processed junk and cured red meats. Sinclair's book appears to advocate a largely vegetable based diet for lowest risk (in terms of food choices) of premature death from the usual suspects. Luckily I love my vegetables, so that suits me fine although I'm not a vegetarian. I eat a fair bit of chicken and fish. Exercise is a no-brainer for me, so that's good news.

I mostly agree, but I believe there are certain food types worth avoiding. At least in terms of our regular diet. A lot of people I know make some pretty poor dietary choices and it shows.

I can relate to that. It's you that appears to have a problem relating to other people actually enjoying the things you may find unpleasant.

Yeah, we have similar habits and only eat red meat once or twice a month. I wish I were more motivated to eat my veggies though, especially in the winter.

Ditto. My wife and I have given up pork and beef for long term health reasons as well as their climatic and environmental impact. We eat a lot of fruit, veges, fish and occasional chicken. I supplement my diet with protein powder. I have no issue with beef consumers since lean beef is an excellent source of protein, vitamin and minerals. And then there are those chocolate chip cookies she keeps baking….

Red meat consumption directly correlates to incidence of colon and prostrate cancer in countries. Lean or not it is the animal protein that stimulates the growth of cancer cells. Beans of all kinds are an excellent source of protein and of fiber and they are free of man made pesticides and herbicides and growth hormones (which occurs naturally in animal milk as it is intended to promote rapid growth of offspring). The study that first demonstrated causation between protein consumption and cancer used whey protein for the animal protein source.

I have long thought that the typical non-American diet where meat is more of a condiment than a primary aspect of the meal. One sees this with all the Asian cuisines where the portion that is meat if less than 20% of the dish.

I'd agree, from my research and personal experience, I think they're neck and neck. Unfortunately, that also holds true for how they're viewed by mainstream medicine, at least in western medicine, where attention to the healing and preventative aspects of good nutrition, tailored to the individual, barely scratches the surface. Most medical schools don't even require any nutrition studies from what I understand, and it's just a token amount and outdated when they do. And as for exercise, people are essentially encouraged to do as little as possibly necessary, just so much as to check it off the list before you go back to the couch. Beyond that, all they have to offer are drugs and surgery if something goes awry.

Only free of noxious chemicals if they are organic beans. Link for that cancer study?
Recent Findings: Whey protein, present in dairy products, is an excellent source of the sulphur amino acid cysteine, the rate limiting substrate in glutathione synthesis. Notably, this protein survives digestion and has been shown to have anti-carcinogenic properties in animal studies.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4278910/
Whey protein up-regulates glutathione production, a powerful cellular protector that prevents cancer formation, increases elimination of carcinogens and induces apoptosis. Vegan proteins do not increase glutathione in same as whey since they have lower levels of the amino acid cysteine, a key glutathione precursor. One interesting study that compared whey vs soy protein and found whey was superior in tumor prevention.

To keep things straight, prostate - an organ (gland) of the body; prostrate - lying face down.

Beans are also a crappy protein source, unless you eat them with rice or another source of methionine, but when you've got superior knowledge...

My old Doc had me taking N-Acetyl-L-Cysteine forever and also when I could afford it, glutathione injections. I just ran out of NAC, need to reorder.

I don't know if there is any truth to this statement or not, but a biologist once told me that the human body was completely (regenerated) every 7 years. I think that's the word I'm looking for. I'm having a senior moment here.
