HEALTH BENEFITS OF MUSHROOMS
It's common knowledge that the key to getting enough vitamins and minerals in the diet is to eat a colorful variety of fruits and vegetables - the more color, the better. However, this philosophy tends to leave mushrooms in the dark. In many cases, if a food lacks color, it also in turn lacks necessary nutrients. However, mushrooms - which are commonly white - prove quite the contrary.
One cup of chopped or sliced raw white mushrooms contains 15 calories, 0 grams of fat, 2.2 grams of protein, 2.3 grams of carbohydrate (including 0.7 grams of fiber and 1.4 grams of sugar). Although there are a large variety of mushrooms available, most provide the same amount of the same nutrients per serving, regardless of their shape or size.
Mushrooms are rich in B vitamins such as riboflavin, folate, thiamine, pantothenic acid, and niacin. They are also the only vegan, non-fortified dietary source of vitamin D . Mushrooms also provide several minerals that may be difficult to obtain in the diet, such as selenium, potassium, copper, iron, and phosphorus.
Beta-glucans are a type of fiber that is found in the cell walls of many types of mushrooms. Recently, beta-glucans have been the subject of extensive studies that have examined their role in improving insulin resistance and blood cholesterol levels, lowering the risk of obesity and providing an immunity boost.
Mushrooms also contain choline; an important nutrient found that helps with sleep, muscle movement, learning and memory. Choline assists in maintaining the structure of cellular membranes, aids in the transmission of nerve impulses, supports proper fat absorption and reduces chronic inflammation
Consuming fruits and vegetables of all kinds has long been associated with a reduced risk of many lifestyle-related health conditions. Countless studies have suggested that increasing consumption of naturally-grown foods like mushrooms decreases the risk of obesity and overall mortality, diabetes, heart disease and promotes a healthy complexion and hair, increased energy, and overall lower weight.
Mushrooms contain just as high an antioxidant capacity as carrots, tomatoes, green and red peppers, pumpkins, green beans, and zucchini.
Selenium is a mineral that is not present in most fruits and vegetables but can be found in mushrooms. It plays a role in liver enzyme function, and helps detoxify some cancer-causing compounds in the body. Additionally, selenium prevents inflammation and also decrease tumor growth rates.
The vitamin D in mushrooms has also been shown to inhibit the growth of cancer cells by contributing to the regulation of the cell growth cycle. The folate in mushrooms plays an important role in DNA synthesis and repair, thus preventing the formation of cancer cells from mutations in the DNA.
Studies have shown that type 1 diabetics who consume high-fiber diets have lower blood glucose levels and type 2 diabetics may have improved blood sugar, lipids and insulin levels. One cup of grilled portabella mushrooms and one cup of stir-fried shiitake mushrooms both provide about 3 grams of fiber.
The recommends 21-25 g/day for women and 30-38 g/day for men
The fiber, potassium and vitamin C content in mushrooms all contribute to cardiovascular health. Potassium and sodium work together in the body to help regulate blood pressure . Consuming mushrooms, which are high in potassium and low in sodium helps to lower blood pressure and decrease the risk of hypertyension and cardiovascular diseases.
Additionally, an intake of 3 grams of beta-glucans per day can lower blood cholesterol levels by 5%.
Selenium has also been found to improve immune response to infection by stimulating production of killer T-cells. The beta-glucan fibers found in the cell walls of mushrooms stimulate the immune system to fight cancer cells and prevent tumors from forming
Dietary fiber plays an important role in weight management by functioning as a "bulking agent" in the digestive system. Mushrooms contain two types of dietary fibers in their cell walls: beta-glucans and chitin which increase satiety and reduce appetite, making you feel fuller longer and thereby lowering your overall calorie intake.
