Researchers from Oxford University, the University of Oslo, and the University of Bergen evaluated the connection between fish consumption and cognitive performance in 2031 subjects 70 to 74 years of age. People who had an average intake of 10 grams or more of fish each day performed better on cognitive function tests on average, and had a lower rate of poor performance than those who consumed less than 10 grams per day. The higher the intake of fish the better the cognitive performance with the best performance achieved at 75 grams or more of fish each day.

Many studies report severe Vitamin D deficiency in elderly women and its involvement in various health problems but not enough are known about levels in elderly men. In this study 291 men aged 65 or older living either at home or in institutions for the elderly had their blood levels of active Vitamin D compared with their health; these men were not taking Vitamin D supplements at the time of enrollment into the study. An additional 45 men initially enrolled in the study were excluded because they were already taking Vitamin D supplements.

Scientists and physicians from various research institutions and hospitals in Asia split patients with (very dangerous) head and neck cancers into two groups; both groups received radiation treatment for their cancer, but one group was placed on inactive placebo while the second group received a Zinc supplement. Both groups of 50 patients were very similar in the characteristics of their cancer, their medical histories, and treatment details. By the third year there was slightly better 3-year survival in the Zinc group with better local free survival.

Haptoglobin is a powerful antioxidant protein in our blood. Haptoglobin binds to free oxy-hemoglobin, a form of the substance in blood that carries oxygen, and prevents it from becoming cross linked; otherwise glycosylated hemoglobin would form, and this form of hemoglobin hardens tissues and reduces cellular function in a process that greatly accelerates aging in diabetics. In fact a major diagnostic tool doctors use to judge the effectiveness of a diabetics blood sugar control is a measure of the level of glycosylated hemoglobin; if it is high it shows poor blood sugar control over a two or three-month period.
