Ø Both common and specialty mushrooms inhibit the cellular processes associated with early heart disease
§ Ergotheoneine is a natural antioxidant, first discovered in ergot. Cannot be synthesized by humans, so must be obtained in the diet. Also found in beans and oat bran, ruminant liver and kidney. But mushrooms have the highest concentration!!
§ Inhibits adhesion molecule expression and in vitro binding of monocytes to human aortic endothelial cells in a pro-inflammatory environment characteristic of early cardiovascular disease
Mushrooms can help reduce cardiovascular disease
