NYT has two good articles out that vindicate yet again two of my primary principals of good health. The first article reports findings that diabetics on a low glycemic index (GI) diet have a lower instance of heart disease than those on the standard whole grain (higher GI) diet, among other health benefits. I've been convinced for some time that the best diet for weight control and optimal health is a low GI diet. The second article reports findings that, "People with more lean muscle mass may have an advantage when it comes to fighting cancer," and may even have lower risk for some cancers. This I had not heard, but again, I know maintaining lean muscle mass as we age is critical to remaining healthy and vigorous. Exhibit A: Jack Lalanne at 90!
