The IOC Diploma Sports Nutrition YouTube channel has a collection of very interesting videos about Sports Nutrition.
Short and to the point videos, providing specific answers by the world leading experts on the field to questions like Can caffeine improve fat loss?, What carbohydrate intake would you recommend for an ultra athlete? or What is the best source of protein?.
Be warned, if you are interested in the field these videos are really addictive. I can't stop watching them.
