Radioprotective effect of the Barbados Cherry (Malpighia glabra L.) against radiopharmaceutical Iodine-131 in Wistar rats in vivo

Posted January 31, 2014

The increasing consumption of fruits and vegetables has contributed to the improvement of populational health, due in part, to the abundance of antioxidants in these foods. Antioxidants reduce the level of oxidative damage to DNA caused by free radicals and ionizing radiation, including the radioisotope iodine-131 (131I). This isotope is used for the diagnosis and treatment of thyroid injuries, such as hyperthyroidism and cancer.

Nutrition tied to improved sperm DNA quality in older men

Posted August 27, 2012

A new study led by scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) found that a healthy intake of micronutrients is strongly associated with improved sperm DNA quality in older men. In younger men, however, a higher intake of micronutrients didn’t improve their sperm DNA.

Zeaxanthin improves vision in night driving study

Posted April 30, 2012

A recent study published in the November 2011 Journal of Optometry confirms improved vision in elderly patients through nutritional supplementation. The Zeaxanthin (zee-uh-zan-thin) and Visual Function Study (ZVF), conducted by eye nutrition pioneer Stuart Richer, PhD, OD at the Veterans Administration Hospital in Chicago, shows scientific evidence that dietary Zeaxanthin improved vision in night driving and fine detail, among others.
