4. Brain Food

The science of whether some dietary choices are really “brain food” continues to unfold.

The growth in our knowledge and understanding of the disease combined with our increasing lifespan and the aging of the baby-boomer generation has led

6. Meet the Macronutrients

Much of the debate in recent years about how best to feed your heart and brain has focused on “macronutrients”—proteins, carbohydrates, and fats.
