Omega-3 fatty acids are essential nutrients that we must get from our diets because our bodies cannot make them; they are crucial for early brain development, and there is much evidence that they promote cardiovascular health and cognitive function.

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 right raw materials can... double or triple the protective power of the immune system.

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.

We have these weapons of mass destruction on every street corner, and they're called donuts, cheeseburgers, French fries, potato chips, junk food. Our kids are living on a junk food diet.

The American diet causes disease. It is composed of 25 percent animal products and 62 percent processed foods and only 5 percent of calories from fruits and vegetables.

High salt intake is a risk factor for osteoporosis because excess dietary sodium promotes urinary calcium loss, leading to calcium loss from bone and therefore decreased bone density.

Three of the most beneficial, longevity promoting anti-cancer foods are green vegetables, beans, and onions.

Onions, along with leeks, garlic, shallots and scallions, make up the allium family of vegetables, which can have beneficial effects on the cardiovascular and immune systems, as well as possible anti-diabetic and anti-cancer effects.

Hypertension is an important risk factor for kidney disease, but dietary sodium has other damaging effects on the kidneys. High salt intake drives the production of oxygen radicals, leading to oxidative stress in kidney tissue.

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.

Sodium is an important mineral that is essential for proper functioning of the human body - however, the American diet contains dangerously high amounts of sodium, almost 80 percent of which comes from processed and restaurant foods.

The problem with the standard American diet, a primary cause of our current obesity epidemic, is the fact that the majority of foods consumed are high in calories and low in micronutrients.

The vast preponderance of evidence in modern epidemiology shows that those who eat more whole plant foods and fewer animal products and processed foods have lower rates of chronic disease and longer lifespans.

Cutting back on calories is not the answer to successful weight loss and successful health... you have to increase the quality of what you eat, not just reduce the quantity.

Excess dietary salt is most notorious for increasing blood pressure. Americans have a 90 percent lifetime probability of developing high blood pressure - so even if your blood pressure is normal now, if you continue to eat the typical American diet, you will be at risk.

The human body is a miraculous self-healing machine, but those self-repair systems require a nutrient-dense diet.

I have serious concerns about the potential risks of taking lots of fish oil capsules. So much fish oil can have paradoxical effects, reducing immune function in later life.
