New Research Expands the Capability of Personalized Nutrition

You’re so unique that it was a one in 400 trillion chance that you turned out the way you did. What are the chances, then, that you would need the exact same nutritional recommendations?

Whole Fruit Versus Fruit Juice: You are What You Eat (and Drink)

Everything that makes up your physical body came in through your mouth. You are literally made-up of the things you consume—the good, the bad, and the ugly.
