Smoking vs. Kale Juice

The effect of kale juice on LDL and HDL cholesterol, and the antioxidant capacity of the blood.



So Should We Drink Beet Juice, or Not?

In the context of a healthy, plant-based diet, the nitrates in vegetables can safely be converted into nitric oxide, which can boost athletic performance, and may help prevent heart disease.



Carcinogens in the Smell of Frying Bacon

Frying bacon outdoors decreases the concentration of airborne nitrosamine carcinogens.



Are Nitrates Pollutants or Nutrients?

Phytonutrients, such as vitamin C, prevent the formation of nitrosamines from nitrites—which explains why adding nitrite preservatives to processed meat can be harmful, but adding more vegetables, with their nitrite-forming nitrates, to our diet can be helpful.



Vegetables Rate by Nitrate

If nitrates can boost athletic performance and protect against heart disease, which vegetables have the most—beans, bulb vegetables (like garlic and onions), fruiting vegetables (like eggplant and squash), greens (such as arugula), mushrooms, root vegetables (such as carrots and beets), or stem vegetables (such as celery and rhubarb)?



Hearts Shouldn’t Skip a Beet

The nitrate in vegetables, which the body can turn into the vasodilator nitric oxide, may help explain the role dark green leafy vegetables play in the prevention and treatment of hypertension (high blood pressure) and heart disease.



Asparagus Pee

Young infants, and perhaps those with recurrent oxalate kidney stones, should avoid beets. But most commonly, the chief side effect is beeturia, the harmless passage of pink urine, though not all are affected—akin to the malodorous urine (“stinky pee”) that sometimes results from asparagus consumption.



Out of the Lab Onto the Track

Randomized, double-blind, placebo-controlled, crossover studies convinced the scientific establishment that nitrate-rich vegetables (such as beets) could noticeably improve athletic performance.



Don’t Use Antiseptic Mouthwash

The natural flora on our tongue (lingual bacteria) are essential for the athletic performance-enhancing effect of the nitrates in vegetables such as beetroot.



Priming the Proton Pump

To understand how beets could reduce the oxygen cost of exercise while improving athletic performance, one must review the biochemistry of energy production (ATP synthase), and the body’s conversion of nitrates to nitrites into nitric oxide.



Doping with Beet Juice

Beets found to significantly improve athletic performance while reducing oxygen needs—upsetting a fundamental tenet of sports physiology.



Doctors Know Less Than They Think About Nutrition

Doctors found to be overconfident in their knowledge and ability to counsel patients about lifestyle modification for chronic disease prevention.



Dietary Guidelines: Corporate Guidance

Nearly 2,000 comments were submitted to the U.S. Dietary Guidelines Advisory Committee. Watch what the Sugar Association, National Cattlemen’s Beef Association, and the chewing gum company, Wrigley’s, had to say.



The Tomato Effect

Why does the medical establishment sometimes ignore highly efficacious therapies, such as plant-based diets, for heart disease prevention and treatment?



China Study on Sudden Cardiac Death

The China-Oxford-Cornell Diet and Health Project directed by T. Colin Campbell and colleagues showed that chronic diseases, such as heart disease, are not inevitable consequences of aging.



Our #1 Killer Can Be Stopped

Dr. Dean Ornish proved decades ago that heart disease could be reversed solely with diet and lifestyle changes.



Resuscitating Medicare

Medicare is now accepting for reimbursement the Dean Ornish Program for Reversing Heart Disease and the Pritikin Program, which, on a personal note, is what inspired me to go into medicine.



Rosy Glow

Erectile dysfunction may be an early warning sign for heart disease.



Do Doctors Make the Grade?

Doctors and other health professionals were put to the test for their nutrition knowledge regarding diet and heart disease.



Slowing the Growth of Cancer

Researchers discovered a dietary intervention that may slow the progression of cancer.
