Nutrition expert Katherine Brooking, MS, RD, reveals 10 surprising foods that may benefit your health in ways you never imagined.
If you think mushrooms add flavor, but no real nutrition, here's some intriguing news: Mushrooms are the only vegetable source of vitamin D, a nutrient many people are short on these days. It's a small amount―just 15 international units―but preliminary research suggests sunlight may give it a boost. One study found that exposure to five minutes of ultraviolet light may boost Vitamin D levels in a serving (4 to 5 white button mushrooms) from 4 percent of the Daily Value to as much as 100 percent (400 IU). In addition, many popular mushroom varieties like white, portabella, and crimini are good sources of B vitamins like riboflavin and niacin.
