    Fatima, thank you for your interesting article. However it leaves me with confusion as to quantities. Early you mention The USDA recommend including nuts at 4 ounces per week in your 2000 calorie diet, but subsequently mention for example 3, 1 oz.servings of walnuts per week and later that nutritionists recommend consuming walnuts up to 2 ounces daily. 1.5 oz./day of peanuts are recommended, 2 oz./day of almonds to get the full benefit. Do you have a guideline for mixed nuts per day?
