Nutritionists debunk 19 diet myths

Two nutritionists debunk 19 of the most common myths about diets. They explain why dairy affects those with lactose intolerance and why they can actually eat cheese. They also debunk the idea that red wine is good for your heart. Turns out, just because it's made of fruit doesn't mean it's good for you. And they mention how much water we actually should be drinking every day.
