Caffeine Appears To Be Beneficial In Males–But Not Females–With Lou Gehrig’s Disease

Animal model highlights the effect of diet and gender in understanding ALS

NEW ORLEANS—Amyotrophic lateral sclerosis (ALS) is a fatal disease that damages key neurons in the brain and spinal cord. The disease causes progressive paralysis of voluntary muscles and often death within five years of symptoms. Although ALS (Lou Gehrig’s disease) was discovered over a century ago, neither the cause nor a cure have been found, but several mechanisms seem to play a role in its development, including oxidative stress.

Coffee, Caffeine and ALS

Researchers agree that ALS is a multifactorial disease that involves a complex interplay between a genetic predisposition and environmental factors. One environmental factor is diet. With oxidative stress (which damages the cells) a common concern in ALS pathology, it is worth examining what role antioxidants (which confer benefits to the cells) might play.

Antioxidants (the vitamins and nutrients that protect the cells from damage) are found in commonly consumed beverages and foods. Coffee in particular has received attention as a potent dietary antioxidant. It is worth noting that coffee has significantly more antioxidant capacity than cocoa and green, black or herbal teas. However, coffee contains several components, the largest of which are caffeine and chlorogenic acid, a dietary polyphenol that is beneficial to the immune system.

Previous studies have shown positive effects with coffee, caffeine, or chlorogenic acid supplementation in improving oxidative stress and its associated cell death mechanisms.
