The American Mushroom Institute states that mushrooms are great to eat raw or incorporated into dishes. Mushrooms contain B vitamins, niacin, riboflavin, selenium, fiber and potassium. According to the U.S. Food and Drug Administration nutrition analysis, a half-cup serving of white button mushrooms contains 2% of the recommended daily value of vitamin C and iron, based on a 2,000-calorie diet.
White button mushrooms contain no fat or cholesterol, and they are low in calories and sodium, with about 20 calories and 5 mg sodium per half-cup.
Preserving mushrooms
(Note: Wild mushrooms should not be preserved.)
Research-tested preservation methods are available for canning, pickling, drying and freezing mushrooms. Step-by-step instructions for preserving mushrooms can be found in âSo Easy to Preserve,â by Cooperative Extension of the University of Georgia.
