Quote from CET:
I am only aware of red yeast rice being used to lower cholesterol. You need to be aware that it is a statin, which can elevate your liver enzymes, just like the cholesterol drugs. FWIW, the cholesterol drugs were developed from red yeast rice, since the big "dealers" must have a synthetic compound to get a patent and make money. Make sure you do your homework on the amount to take, and buy the red yeast rice from a reputable provider.
Everyone should consider taking fish oil, as it greatly improves brain function. Just make sure it has been distilled to remove any mercury from the source, which is a concern these days as we pollute everything.
If you drink coffee or are not avoiding caffeine I highly suggest you drink green tea. You get the benefit of caffeine without the jitteryness of coffee. In addition, green tea contains EGCG, and it has many health benefits. You can also get green tea extract if you want to avoid the caffeine.
While there are a number of healthy nuts, I believe almonds are the best for you. Walnuts and peanuts have many healthy components, but they are acidic to your system.
Anyone wanting to improve their diet should do a search on foods and body pH. You many also want to check out whey protein, as it gives you protein without the huge acidic impact on your body that meat proteins do.
