You can be in excellent physical shape, with low cholesterol, a healthy body weight and good overall physical fitness - but that doesn't necessarily mean you're healthy.
Milk contains growth hormones designed by Mother Nature to put a few hundred pounds on a baby calf within a few months.
When any fat is heated to frying temperatures, toxic volatile chemicals that can cause genetic mutations are released into the air.
Don't forget that fruit can be cooked - think of baked apples, poached pears and grilled pineapple. But if you like drinking fruit, blending will preserve more nutrition and fibre than juicing.
Berries are the healthiest fruit, offering potential protection against cancer and heart disease, boosting the immune system and acting as a guard for the liver and brain.
A placebo-controlled, double-blind, randomised trial of boys with autism found that two to three servings of cruciferous vegetables a day improves social interaction, abnormal behaviour and verbal communication - within a matter of weeks.
As a physician specializing in nutrition, my priority is to the health of the public.
Nutrition is an exciting, dynamic field - there are more than 10,000 articles published on human nutrition in medical journals every year.
When the FDA announced its intentions to join other countries and ban quinolone use on U.S. chicken farms, the drug manufacturer Bayer initiated legal action that successfully delayed the process for five years.
Despite the growing evidence of health benefits associated with coffee consumption, I still don't recommend my patients drink it - not because it's not healthy, but because there are even healthier choices.
Everyone feels sad occasionally. A full range of emotions is part of what makes us human.
Eating a varied plant-based diet - and avoiding all meat, fish, chicken and dairy products - may have much to recommend it, but it's certainly not for everyone.
Scientists suggest that the link between consuming poultry and cancer spread may be due to carcinogens in cooked meat. For unknown reasons, these carcinogens build up more in the muscles of chickens and turkeys than in those of other animals.
About a quarter of lung cancer cases occur in people who have never smoked. One cause may be another potential carcinogen: fumes from frying.
Tart cherries lower the levels of inflammation in the body, which may be particularly useful for those who suffer from gout. They have also been used to improve sleep.
Popeye was right about spinach: dark green, leafy vegetables are the healthiest food on the planet. As whole foods go, they offer the most nutrition per calorie.
Broccoli is incredible. It can prevent DNA damage and metastatic cancer spread; activate defences against pathogens and pollutants; help to prevent lymphoma; boost the enzymes that detox your liver; target breast cancer stem cells; and reduce the risk of prostate cancer progression.
The USDA is tasked with managing and promoting agriculture - including the well-funded animal agriculture industry - so it's pulled into a tug-of-war every time the dietary guidelines are re-evaluated.
Remove all the junk from one's house. Then one doesn't have to deal with the temptation. If you get hungry enough, you will eat that apple.
Though pigs have been proven susceptible to a porcine spongiform encephalopathy, the National Pork Producers Council claims that no naturally occurring cases of 'mad pig' disease have ever been discovered.
Up to a thousand milligrams of caffeine is considered safe for most people, which translates into about 10 cups of coffee a day.
Mental health can be just as important as physical health - and major depression is one of the most commonly diagnosed mental illnesses.
Even if you were to start drinking milk during adolescence in an attempt to bolster peak bone mass, it probably wouldn't reduce your chances of fracture later in life.
The fumes produced by frying bacon contain carcinogens called nitrosamines. Though all meat may release potentially carcinogenic fumes, processed meat such as bacon may be the worst.
Tobacco smoke contains chemicals that weaken the body's immune system, making it more susceptible to disease and handicapping its ability to destroy cancer cells.
Studies on cherries, raspberries and strawberries suggest that most of their nutrition is retained when they're frozen, so it's a good idea to keep some in the freezer.
Sadly, commercially-produced, frozen broccoli lacks the ability to form sulforaphane because the vegetables are flash-cooked before they are frozen.
The benefits of a healthier diet are far-reaching because they also equate to fewer animals being bred into inhumane factory farm conditions and fewer greenhouse gas emissions.
Anyone who's promoting the exact diet that they were in previous years probably isn't keeping up with the latest science, though in general, the balance of evidence has remained remarkably consistent - centering one's diet around whole plant foods.
While consumers may be more shocked by pink slime or the feeding of Prozac to poultry, the routine feeding of millions of pounds of human antibiotics to chickens presents a much graver threat.
Sick animals can lead to sick people.
One of the reasons it's so difficult to study the relationship between diet and disease is because many dietary behaviors are associated with non-dietary behaviors.
