I hear this all the time and it's the headline on Yahoo News right now. Look, there is no question that some foods contain more essential nutrients and vitamins then other foods. But nobody ever stops to wonder, "Gee, how many essential nutrients and vitamins do we really need ?" Think about it, we are living in an era which appears to be unique in human history. That is, food is abundant for us. And not only that, owing to a host of technological breakthroughs in human history (yes, including preservatives), we now enjoy a wider variety of foods than ever before. So, did less food and less variety mean that our ancestors were less healthy than we are today ? Do we need to cram as many nutrients and vitamins as we can to enjoy optimum health ? And doesn't that lead to overeating ? Recently I read that the average-sized woman can get all her RDA's of carbs, proteins and fats on 800 calories a day. And I would add that most of the processed foods we eat are heavily fortified with vitamins.
