Eat Sun-Dried Mushrooms For Loads of Vitamin D

Blog

In many parts of the country, winters can be long and the exposure to sunlight limited. Even in the summer months, people can still be vitamin D deficient because sunscreen can block the absorption of Vitamin D.

Why do we need vitamin D? According to a study published in The American Journal of Geriatric Psychiatry, vitamin D deficiency is associated with low mood and poor cognitive performance. In his 2004 article published in The American Journal of Clinical Nutrition, Michael F. Hollick summarizes the research that links the lack of vitamin D to auto-immune diseases, cancer, and cardiovascular diseases.

How much vitamin D do we need? The FDA recommends that we consume 400 IU of vitamin D daily. However, the Institute of Medicine, a branch of the National Academy of Sciences, issued new recommendations for dosages of vitamin D, which include 600 IU per day for people up to age 70, and 800 IU for those over 70. Many doctors and nutritionists recommend 800-1000 IU daily.

Are we getting enough vitamin D? In his article Vitamin D: Why You Are Probably NOT Getting Enough and How That Makes You Sick in the Huffington Post, Dr. Mark Hyman, author and founder of The Wellness Center in Lenox, Massachusetts, reports that “70-80 percent of the population is vitamin D deficient.” Two recent studies in the journal Pediatrics found that 70 percent of American kids aren’t getting enough vitamin D. This can have grave consequences. A vitamin D deficiency in children puts them at greater risk of obesity, diabetes, high blood pressure, lower levels of good cholesterol, and an increased risk of developing heart disease later in life. Dr. Hyman indicates that “7.6 million, or nine percent, of US children were vitamin-D deficient, and another 50.8 million, or 61 percent, had insufficient levels of this important vitamin in their blood.”

How can I get more vitamin D naturally? That’s simple: sun-dried mushrooms.

How much vitamin D is in sun-exposed mushrooms? Experiments conducted by Fungi Perfecti Research Laboratories in 2004, in accordance with the standards to the Official Methods of Analysis of AOAAC International, produced some amazing results:

There you have it: 100 grams of shiitake mushrooms dried in the sun with the gills facing up have 460 times more vitamin D than one standard dose (1,000 IU) of a manufactured, store-bought vitamin D pill! So, wait no longer. Grow and sun-dry your own mushrooms for a fantastic supply of food-based vitamin D!
