Scientists have struggled to explain why influenza is so common during the winter and why it infects so many elderly people. A fascinating new theory traces flu outbreaks to a widespread vitamin deficiency caused by lack of sunlight—and suggests a simple way that aging adults can guard against flu and other infectious disease associated with winter months.

Magnesium is essential to healthy vascular function, yet most people drink tap, bottled, or filtered waters that are devoid of this critical mineral. Fortunately, optimizing magnesium intake can be easily done through diet, better bottled waters, and supplementation.

As we age, it becomes crucial to take steps to preserve healthy neuronal structure and function. Find out what the best-documented nutrients are to achieve optimal neuronal function while quelling the inflammation that ignites Alzheimer’s and vascular dementia.

Extraordinary new research demonstrates that compounds in pomegranate improve endothelial function by increasing nitric oxide levels, which improves blood flow to the heart and brain, and reverses clinical measurements of atherosclerosis.

Scientists have identified ways to delay the onset of prostate cancer, but as male life spans increase, there is a critical need to prevent relatively dormant cancer cells in the prostate gland from breaking through the body’s protective barriers. In this issue, we describe a little-known pathological mechanism that explains why ingesting the wrong foods increases prostate cancer risk, and introduce a patented plant extract that may provide additional protection via a novel mechanism.

Curry spice supports cognition in older adults; testosterone-deficient men more prone to falling; recurrent viral infections may cause memory loss; olive extract kills colon cancer cells; nutrient combo boosts mitochondrial energy; alpha-lipoic acid improves diabetic neuropathy; DHA suppresses production of fat cells; folate-deficient diet may raise colon cancer risk; high vegetable consumption slows cognitive decline; and more.

Dr. Eric Braverman discusses how our organ systems age differently and the merits of a whole-body approach to halting premature aging.

Still going strong at 88, silver-mining legend Justin Rice maintains a work schedule that would challenge most men half his age.
