Mushrooms appear to have an anti-inflammatory effect on human arterial lining cells in vitro, which may help stop the inflammatory cascade, thought to be integral to the progression of atherosclerotic (artery-clogging) heart disease. The effects of shitake, crimini, oyster, maitake, and plain white button mushrooms are compared.
For more magic from plain white mushrooms, see Vegetables Versus Breast Cancer and Breast Cancer Prevention: Which Mushroom is Best? Just make sure to cook them (see Toxins in Raw Mushrooms?). In terms of anti-inflammatory foods in general, check out Anti-Inflammatory Antioxidants; Garden Variety Anti-Inflammation; Aspirin Levels in Plant Foods; and Dried Apples Versus Cholesterol. In terms of pro-inflammatory foods, see my four-part video series Improving Mood Through Diet; Inflammatory Remarks About Arachidonic Acid; Chicken, Eggs, and Inflammation; and Chicken’s Fate is Sealed.
