Certainly adding fats in the form of oils is fattening and unhealthy, but naturally fat-rich foods like nuts and seeds have profound cardiovascular benefits.

The diet, to be healthy, has to be mostly fruits, vegetables, beans, nuts and seeds.

Seeds and nuts are indispensable for cardiovascular health. The protective properties of nuts against coronary heart disease were first recognized in the early 1990s, and a strong body of literature has followed, confirming these original findings.

Blueberries, strawberries and blackberries are true super foods. Naturally sweet and juicy, berries are low in sugar and high in nutrients - they are among the best foods you can eat.

The human diet, for millions of years, did not contain any added salt - only the sodium present in natural foods, adding up to only about 1000 mg sodium per day.

Preferring healthful foods is a skill, and skills take practice and perseverance to develop.
