Mushrooms…What Are They Good For?

mushrooms3Mushrooms are classified as vegetables, but they aren’t technically plants, they belong to the fungi kingdom, and they contain important nutrients, vitamins, and minerals.

Mushrooms provide several important nutrients, as well as being low in sodium, fat, cholesterol, and calories.  Mushrooms may help prevent chronic disease due to the presence of antioxidants and beneficial dietary fibers such as chitin and beta-glucans.

Mushrooms are rich in B vitamins such as riboflavin, folate, thiamine, pantothenic acid,  and niacin. They are the only vegan, dietary source of vitamin D.

Mushrooms also provide several minerals such as selenium, potassium, copper, iron, and phosphorus.

Excellent source of selenium

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.  Several types of mushrooms are rich in this essential trace mineral: 100 grams of raw crimini have 47 percent of your daily needs, shiitakes have 45 percent and raw white button have 17 percent.

Rich source of Vitamin B2 and B3

Mushrooms contain high levels of vitamin B2 (riboflavin) and vitamin B3 (niacin): 100 grams (31/2 ounces) of crimini have 44 percent  – that’s 30 percent of your daily recommended amount.

Rich source of Vitamin D

The vitamin D in mushrooms has 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.

*Mushrooms that have been grown in the dark and have not been exposed to either sun light  or by a brief zap of ultra violet light, will not contain the same levels of vitamin D.

Improves immune function:

Long chain polysaccharides  such as alpha and beta glucan molecules, are responsible for the mushrooms’ beneficial effect on the immune system. Mushrooms may increase the production of antiviral and other proteins that are released by cells while they are trying to protect and repair the body’s tissues.

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.

High in antioxidants

Antioxidants are the “substances” that help fight free radicals that are the result of oxidation in our body.  Mushrooms contain just as high an antioxidant capacity as carrots, tomatoes, and red peppers.

So the next time you’re at the grocery store, try adding some mushrooms into your diet.

Coffee, Tea and Caffeine

coffee-teaCaffeine has many effects on the body’s metabolism, and is naturally found in certain leaves, beans, and fruits of over 60 plants worldwide.

Studies have shown that moderate consumption of caffeine, whether in coffee or tea may reduce your risk of diabetes, Parkinson’s disease, Alzheimer’s disease, and certain cancers.

Facts on Tea & Coffee:

  • White tea is unfermented and offers the most powerful antioxidant levels of all the teas.
  • Black tea is made from fermented leaves and has the lowest levels in monomeric catechins due to the fermentation process, which have been linked to cancer prevention.
  • Green tea is full of antioxidants that may help prevent different types of cancer including breast, lung and stomach.
  • White tea has the highest concentration of antioxidants and may actually be more effective preventing some diseases than green tea.
  • Tea contains fluoride which protects teeth.
  • Tea hydrates.
  • Studies have shown that tea helps prevents the development of type 1 diabetes.
  • Tea protects against lung cancer.
  • Coffee caffeine has been linked to improved memory recall and may also help prevent Alzheimer’s, heart disease, type 2 diabetes and can help ease asthma attacks.
  • Caffeine increases the effectiveness of pain killers.
  • Coffee protects the liver, against cirrhosis and cancer.
  • Coffee improves short term recall as well as improves reaction times.
  •  Green and black teas contain anti-inflammatory antioxidants that are good for preventing and managing arthritis, memory problems, and cataracts.
  • Drinking tea too hot increases the risk of esophageal cancer.
  • White tea may help prevent obesity by inhibiting the growth of new fat cells.
  • Caffeinated coffee has been shown to help prevent memory loss and decrease the risk of certain cancers.
  • Drinking coffee over a long period of time, may reduce the risk of dying from heart disease and are less likely to suffer from Alzheimer’s disease later in life.
  • Over 1000 chemicals have been found in roasted coffee with 19 being known carcinogens.

Caffeine amounts per an average cup ( 8oz/237 ml):

Tea:        Black tea 90mg     White tea 75mg      Green tea 50mg

Coffee:   Brewed 135mg       Espresso 40mg

*espresso is served in much smaller volumes, so less caffeine; from a volume perspective, espresso has much more caffeine than brewed coffee. 

Caffeine intake levels:

  • a low to moderate intake is 130 mg-300 mg per day
  • a moderate is 200 mg-300 mg per day
  • high doses are above 400 mg per day
  • heavy caffeine consumption is more than 6,000 mg/day.

As with most things in life: everything in moderation including drinking coffee and tea.
