Questions and Answers – Nutritional Data on Portabella Mushrooms
I hope you can answer this for me. What is the nutritional value of Portabella mushrooms ? I’ve read that they can be used as a meat substitute, does this mean that they contain protein? I would have assumed that they would be classified as a vegetable. Please elaborate as I am on a lifetime healthy eating plan and need to know where to include them in a balanced diet. I was told that they are wonderful and would like to try them. Thanks – Kathi (9/10/01)
Many myths have been spread about mushrooms, being one of the most inaccurate that mushrooms have no nutritional value. To properly consider their nutritional benefits, they must be viewed from a dried weight perspective and give you maximum nutritional benefit only upon cooking.
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, selenium, potassium and phosphorus. Phytochemicals found in some mushrooms are being studied as possible cancer-fighting substances, according to the American Institute for Cancer Research.
