Eating Mushrooms can Increase Vitamin D Level, Says Scientist

Three or four button mushrooms are sufficient to make vitamin D for the average person's estimated daily needs, says Australian scientist.Professor Rebecca Mason, head of physiology at Sydney Medical School and past president of the ANZ Bone and Mineral Society has found that like humans, button mushrooms also need exposure to sunlight for the photochemical manufacturing to kick into action, News.com.au reported. 
Mason said that button mushrooms need two hours unwrapped on a plate in the midday summer sun and a bit longer in winter to get the vitamin D boost, and placing them a couple of extra hours in the shade will allow time for the full chemical reaction. 
Mason said that eating three or four button mushrooms every day is enough for active people, while people who are housebound could up their dose of button mushrooms to increase their levels of vitamin D.
