Alzheimer's disease may have a genetic link, but nutrition and heavy metal exposure also play a significant role in its development, according to Harold Foster, PhD.

Last fall, at a HANS-sponsored event, a large audience followed Dr. Foster's argument, which involved years of researching the disease in various world populations. With careful precision, the retired University of Victoria professor and author of What Really Causes Alzheimer's Disease (Trafford Publishing, 2004) deconstructed the idea that genes-one of which is the APO E4 allele(s)-are the only factor in this disease. It is this gene's susceptibility to aluminum (a toxic
heavy metal) that increases the risk of developing Alzheimer's by impairing enzymatic function in the brain.

Sources of aluminum that Dr. Foster suggests avoiding include:
• Tap water (check with your water board)
• Antiperspirant deodorants •
• Foods and beverages in aluminum cans

Acidic drinking water is also problematic because it makes aluminum more
soluble, while maltol, added to many processed foods to improve flavour, facilitates the passage of aluminum through the blood-brain barrier.

Minerals-especially calcium and magnesium-are another piece of this puzzle because they hinder aluminum toxicity. Unfortunately, Dr. Foster explained that commercial fertilizers followed by our processing and cooking methods have caused mineral deficiencies from soil to food to humans. To combat this, Dr. Foster suggests supplementing the diet with calcium and magnesium.

Dr. Foster's talk is available on DVD for sale or as a free gift option with a HANS membership.
