Portabella Mushrooms

Portabella mushrooms are just overgrown criminis mushrooms. Pennsylvania and California are the largest mushroom producers. Mushroom "farms" are climate controlled buildings; airflow, temperature and light are all constantly monitored. Mushrooms are low in calories, have no cholesterol and are virtually free of fat and sodium. Mushrooms also contain other essential minerals like Selenium, which works with Vitamin E to produce antioxidants that neutralize "free radicals" which can cause cell damage. Studies have suggested that selenium may reduce the risk of cancer, cardiovascular disease, may slow the progress of HIV disease and may aid in symptoms of rheumatoid arthritis, pancreatitis and asthma. Studies show men who eat selenium rich foods may lower their risk of prostate cancer. Phytochemicals found in some mushrooms are being studied as possible cancer-fighting substances, according to the American Institute for Cancer Research. Mushrooms are relatively high in protein, averaging about 20% of their dried mass. They contribute a wide range of essential amino acids, are low in fat (0.3 - 2.0%), high in fiber and provide several groups of vitamins, particularly thiamine, riboflavin, niacin, biotin, and ascorbic acid. While nutrients vary from one kind of mushroom to the next, many contain protein, vitamins A and C, B-vitamins and minerals including iron, potassium and phosphorus. One Portabella mushroom generally has more potassium than a banana.
