If studies from the 1970s showed cancer patients treated with vitamin C lived 4 times longer and sometimes even 20 times longer, why isn’t it standard practice today?

“Veg-Table” Dietary Nitrate Scoring Method

What is the optimal timing and dose of nitrate-containing vegetables, such as beets and spinach, for improving athletic performance?



What Are the Healthiest Foods?

Based on the Dietary Guidelines for Americans, which foods best supply shortfall nutrients while avoiding disease-promoting components?

Smoothies (and blended soups and sauces) offer a convenient way to boost both the quantity and quality of fruit and vegetable intake by reducing food particle size to help maximize nutrient absorption.



Treating Dry Eye Disease with Diet: Just Add Water?

Causes of dry eye disease include LASIK laser eye surgery, but there are dietary approaches to prevention and treatment.



Heart of Gold: Turmeric vs. Exercise

Diet and exercise synergize to improve endothelial function, the ability of our arteries to relax normally.

The parable of the tiny parachute explains the study that found no relationship between dietary fiber intake and diverticulosis.



The Safety of Heme vs. Non-Heme Iron

Heme iron, the type found predominantly in blood and muscle, is absorbed better than the non-heme iron that predominates in plants, but may increase the risk of cancer, stroke, heart disease, and metabolic syndrome.



Diet and GERD Acid Reflux Heartburn

Which foods should we eat and avoid to prevent and treat acid reflux before it can place us at risk for Barrett’s esophagus and cancer?



Antioxidants and Depression

Neither antioxidant or folic acid supplements seem to help with mood, but the consumption of antioxidant-rich fruits and vegetables and folate-rich beans and greens may lower the risk for depression.



Can Diet Protect Against Kidney Cancer?

Plant-based diets appear to protect against renal cell carcinoma both directly and indirectly.



The Role of Diet in Declining Sperm Counts

The ongoing global drop in male fertility may be associated with saturated fat intake and lack of sufficient fruits and vegetables.



Which Nut Fights Cancer Better?

Within hours the blood of those fed walnuts is able to suppress the growth of breast cancer cells in a petri dish. Which nut might work best, though—almonds, Brazil nuts, cashews, hazelnuts, macadamias, peanuts, pecans, pine nuts, pistachios, or walnuts?



Do Vegetarians Get Enough Protein?

Nutritional quality indices show plant-based diets are the healthiest, but do vegetarians and vegans reach the recommended daily intake of protein?



Turning the Clock Back 14 Years

Four simple health behaviors may cut our risk of chronic disease by nearly 80%, potentially dropping our risk of dying equivalent to that of being 14 years younger.



Cancer Risk from French Fries

The association between cancer and the consumption of deep-fried foods may be due to carcinogens formed at high temperatures in animal foods (heterocyclic amines and polycyclic hydrocarbons) and plant foods (acrylamide).



Treating Asthma with Plants vs. Supplements?

Whole fruits and vegetables were compared to both antioxidant pills, as well as supplements containing fruits and vegetable extracts, for their ability to treat seasonal allergies, improve lung function, and control asthma.



Preventing Asthma with Fruits and Vegetables

A study involving more than a million kids suggests the striking worldwide variation in childhood rates of allergies, asthma, and eczema is related to diet.



How to Slow Brain Aging by Two Years

The consumption of blueberries and strawberries is associated with delayed cognitive aging by as much as 2.5 years—thought to be because of brain-localizing anthocyanin phytonutrients, as shown on functional MRI scans.



Minimum “Recommended Daily Allowance” of Antioxidants

How many antioxidant-rich foods do we need to eat every day just to stay out of oxidative debt?



Nutrient-Dense Approach to Weight Management

Americans eating meat-free diets average higher intakes of nearly every nutrient, while maintaining a lower body weight—perhaps due, in part, to their higher resting metabolic rates.



Enhanced Athletic Recovery without Undermining Adaptation

Might the antioxidant and anti-inflammatory properties of plant-based diets undermine some of the benefits of exercise?



Preventing Exercise-Induced Oxidative Stress with Watercress

Those eating a more plant-based diet may naturally have an enhanced antioxidant defense system to counter the DNA damage caused by free radicals produced by high-intensity exercise.



Keeping Your Hands Warm with Citrus

Phytonutrients in citrus, such as hesperidin, may increase blood flow sufficient to warm the hands and feet of those with cold sensitivity.



Mediating Radiation Exposure from Airline Travel

Based on studies of atomic bomb survivors, Chernobyl victims, and airline pilots exposed to more cosmic rays at high altitudes, it appears that fruits and vegetables may decrease radiation-induced chromosome damage.



Bacterial Vaginosis and Diet

A more plant-based diet may help prevent vaginal infections, one of the most common gynecological problems of young women.



Cranberries vs. Cancer

Drug companies and supplement manufacturers have yet to isolate the components of cranberries that suppress cancer cell growth.



Which Fruit Fights Cancer Better?

The ability of eleven common fruits to suppress cancer cell growth in vitro was compared. Which was most effective—apples, bananas, cranberries, grapefruits, grapes, lemons, oranges, peaches, pears, pineapples, or strawberries?



Fiber vs. Breast Cancer

Inadequate fiber intake appears to be a risk factor for breast cancer, which can explain why women eating plant-based diets may be at lower risk.



Apple Juice May Be Worse than Sugar Water

Why the spike in antioxidant levels in our bloodstream after drinking apple juice might not be a good thing.



Paleolithic Lessons

An evolutionary argument for a plant-based diet is presented, in contrast to “Paleo” fad diets.



Risk Associated with Iron Supplements

Iron is a double-edged sword. If we don’t absorb enough, we risk anemia; but if absorb too much, we may increase our risk of cancer, heart disease, and a number of inflammatory conditions. Because the human body has no mechanism to rid itself of excess iron, one should choose plant-based (non-heme) sources, over which our body has some control.



Some Dietary Supplements May Be More Than a Waste of Money

People taking dietary supplements may, in some cases, be paying to make themselves sick. This video covers folic acid, beta carotene, and green tea supplements.



Apples and Oranges: Dietary Diversity

In addition to quantity and quality, the variety of fruits and vegetables consumed matters, as many phytonutrients are not evenly distributed among the various families and parts of plants.
