Sunscreen with an SPF rating of 15 can block more than 90% of ultraviolet radiation from the sun. Even with this protection, some light still penetrates the skin and creates free radicals. Free radicals are chemicals that have an electron that they can release; it’s kind of like a chemical “bullet”. Antioxidants are like chemical […]

An extract from olives can protect your cells from oxidative stress. Oxidative stress is when certain chemicals release electrons, which act as chemical “bullets” and do damage to cells. Hydroxytrosol is an extract from olives that is a powerful antioxidant (antioxidants act like little chemical “bullet-proof vests”). Earlier research, published in the journal Circulation (2000;102:2169-2171)

Oxidative stress is a threat to health. It can be at the root of serious diseases like heart disease and cancer, or simply make you fatigued. Oxidative stress is caused by chemicals in the diet and in the environment. Many of these chemicals produce free radicals, which are electrons that are not tightly bound to
Research appearing in the Journal of Neuroscience (December 26, 2007, Vol 27, Issue 52, pp 14299-14307) shows that DHA (an omega-3 fatty acid) can increase the production of a protein that helps to block enzymes that are responsible for producing the plaques found in Alzheimer’s disease. The research, found that DHA increases a protein, called

Eat your vegetables and protect yourself from dementia. Vegetables are high in folic acid; the word “folic’ comes from the word “foliage”. Adequate folic acid levels may protect you from dementia. The most common form of dementia is Alzheimer’s disease, affecting about 13 million people worldwide. By mid century the prevalence of Alzheimer’s disease is

A study published in The Lancet (2007 Jan 20:369(9557)208-16) involved 818 subjects who took either 800 mcg of folic acid per day, or a placebo for three years. The subjects had homocysteine levels that were between 13 and 26 micromoles per liter at the start of the study. The group receiving the folic acid had

What exactly is epigallocatechin-3-gallate? It is also called EGCG, and it is a compound found in green tea. Research appearing in the September 21, 2005 issue of the Journal of Neuroscience studied the effect of EGCG on the brains of mice genetically programmed to develop Alzheimer’s disease. The mice were given EGCG injections every day
