How nutrition works in the body is actually a very complex subject.
Researchers are a long way from learning everything they want to know.
But what they've discovered so far is intriguing. They're just beginning to understand how nutrition contributes to and may even help prevent life-threatening illnesses, such as heart disease and cancer. When it comes to old adages, the idea that some nutrients are bad and others are good is slowly being replaced by an understanding of the importance of balance and variety in your diet. In your body, nutrients do their work together. And to do that work at its very best, they must be in balance with one another.
