It's the Resveratrol in the Red Wine that lowers the risk of developing coronary heart disease
Moderately consuming red wine is associated with a lower risk of developing coronary heart disease (CHD).
In this study rabbits were split into five groups. One group was fed a regular diet, the second group was
fed a high cholesterol diet, the next three groups were fed the same high cholesterol diet but were put
on different Resveratrol supplements: Resveratrol with water, Resveratrol in Red Wine, or Resveratrol in
alcohol free Red Wine - all for 12 weeks. The amount of Resveratrol was similar in all three supplements.
This was to assess if it was the alcohol, Resveratrol, or Resveratrol plus alcohol that gave the
cardio-protection. The animals on the high cholesterol diets had significant increases in their
LDL-cholesterol levels compared to those fed a regular diet. The thoracic aorta artery had clearly visible
atherosclerotic lesions in the high cholesterol diet animals, however, the size, density, and average
area of atherosclerotic plaques, and the thickness of the intima media layer was significantly reduced
with all three Resveratrol or Resveratrol plus wine supplements. Rabbits on the high cholesterol diet
had a reduction in decreased endothelial function of the blood vessel walls with a 25% reduction in
flow-mediated dilation, and the Resveratrol supplements prevented this decrease in blood vessel function
and dilation. The Resveratrol and polyphenolics in red wine, rather than the alcohol, suffice in providing
cardiovascular-protective effects. The study is published in the October 2005 issue of the
International Journal of Molecular Medicine.

Ergothioneine is an antioxidant that I have been following for some time but until now there hasn't been
a satisfactory source of this wonderful nutrient. It is a very powerful antioxidant that neutralizes
hydroxyl and peroxynitrate free radicals, blocks mutagen formation, increases the rate of detoxification
in the liver, helps protect the skin from the suns ultraviolet radiation, protects the mitochondria, and
lowers the risk of developing cataracts.
More evidence that the omega-3 fatty acid DHA may help prevent and fight Alzheimer's disease
In the brain of someone with Alzheimer's disease there are tangles of twisted fibers and clumps of
proteins along with massive levels of free radical production and also signs of inflammation. These
protein clumps based on beta-amyloid protein are connected to brain nerve cell death, the hallmark
of this disease. This leads to personality changes, severe progressive memory loss and eventually
DHA is an omega-3 fat found in ocean going fish and seafood. Researchers at Louisiana State
University's Neuroscience center of Excellence found that DHA helped brain cells in two ways:
1) Inhibiting the production of beta-amyloid proteins, the protein found in Alzheimer's brain
2) Boosting the production of a protein known as NPD1. This protein protects brain cells and helps
them stay alive.
The study is published in the September 8th, 2005 issue of The Journal of Clinical Investigation.
