Carrots are known to promote eye health because they contain a lot of vitamin A, but they may also help ward off devastating illness. According to the July ’12 Prevention, people who take vitamin A supplements are 40 percent less likely to develop melanoma than those who don’t supplement.
CLA may boost testosterone. Conjugated linoleic acid is a mix of polyunsaturated fatty acids and is considered a good trans fat. It’s very good for bodybuilders, apparently, as a study by Maculus, et al., that appeared in a 2012 issue of Strength and Conditioning Research (26:6) showed that six grams of CLA a day given to resistance-trained athletes increased testosterone significantly. Milk and meat are good sources, but to get six grams a day, you must supplement.
Red wine is known for its cardiovascular protection, but it appears to boost testosterone as well. Apparently, it does that by inhibiting the enzyme aromatase, which leaves more free testosterone as less is converted to estradiol (J Clin Endocrinol Metab. 89:1174-80; 2004).
Circumin, which is found in turmeric, the main ingredient in curry powder, has been shown to inhibit the growth of cancer cells, according to the November/December ’10 Well Being Journal. It has also been found to lower the incidence of heart failure, so it may be a good idea to supplement with tumeric or circumin.
