Though the most concentrated sources of the toxic metal cadmium are cigarette smoke, seafood, and organ meats, does greater consumption from whole grains and vegetables present a concern?



Gout Treatment with a Cherry on Top

How do sweet cherries compare to the drug allopurinol and a low-purine diet for the treatment of the painful inflammatory arthritis gout?

A new concept in biology tries to explain why the consumption of certain natural compounds in plants may mimic the lifespan-enhancing benefits of caloric restriction.



Appropriating Plant Defenses

Plants and animals share similar biochemical pathways and signaling systems, which may explain why so many phytonutrients are beneficial to our physiology.



Fish and Diabetes

The relationship between fish consumption and diabetes risk may be due to toxic pollutants that build up in the aquatic food chain.



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.



Treating Asthma with Fruits and Vegetables

Increasing fruit and vegetable consumption to seven servings a day appears to cut asthma exacerbation rates in half, whereas restricting consumption to Standard American Diet levels leads to a significant worsening of lung function and asthma control.



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.



Why Do We Age?

A bacteria discovered on Easter Island may hold the key to the proverbial fountain of youth by producing rapamycin, which inhibits the engine-of-aging enzyme TOR.



Phytates for Rehabilitating Cancer Cells

Unlike most other anticancer agents, the phytates naturally found in whole plant foods may trigger cancer cell differentiation, causing them to revert back to behaving more like normal cells.



Phytates for the Prevention of Cancer

Phytic acid (phytate), concentrated in food such as beans, whole grains, and nuts, may help explain lower cancer rates among plant-based populations.



Nuts May Help Prevent Death

Just a few small servings of nuts a week may increase our lifespan and lower cancer risk.



Carcinogen-Blocking Effects of Turmeric

Less than a teaspoon a day of turmeric appears to significantly lower the DNA-mutating ability of cancer-causing substances.



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.



Is Liquid-Smoke Flavoring Carcinogenic?

Different brands of liquid smoke flavorings have been tested for DNA-damaging potential, p53 activation, and levels of known carcinogens. Smoked foods such as ham, turkey, barbequed chicken, herring, and salmon were also tested.



Food Antioxidants, Stroke, and Heart Disease

The oxidation of high-fat and cholesterol-rich foods in our stomachs may help explain why eating antioxidant packed foods appears to reduce heart attack and stroke risk.



Food Antioxidants and Cancer

Antioxidant intake from foods (not supplements) is associated with lower cancer risk.



Turmeric Curcumin and Osteoarthritis

The yellow pigment curcumin in the spice turmeric may work as well as, or better than, anti-inflammatory drugs and painkillers for the treatment of knee osteoarthritis.



Which Spices Fight Inflammation?

An elegant experiment is described in which the blood of those eating different types of spices—such as cloves, ginger, rosemary, and turmeric—is tested for anti-inflammatory capacity.



Dietary Prevention of Age-Related Macular Degeneration

Yellow plant pigments, such as lutein and zeaxanthin, build up in the back of our eyes to protect our retinas against age-related macular degeneration. Levels of these eyesight–saving nutrients in organic free-range eggs, vegetables, and goji berries are compared.



Boosting Natural Killer Cell Activity

Blueberry consumption may double the population of our cancer-fighting immune cells, and the spices cardamom and black pepper may boost their activity.



Vitamin B12 Necessary for Arterial Health

The cardiovascular benefits of plant-based diets may be severely undermined by vitamin B12 deficiency.



Antioxidant-Rich Foods with Every Meal

To stay out of oxidative debt, we need to take in more antioxidants than we use up.



How to Reach the Antioxidant “RDA”

Even nine servings of fruits and vegetables a day may not reach the minimum recommended intake of antioxidants if one doesn’t make the right choices.



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?



Enhanced Athletic Recovery without Undermining Adaptation

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



Methionine Restriction as a Life-Extension Strategy

Plant-based diets may prove to be a useful nutrition strategy in both cancer growth control as well as lifespan extension, because these diets are naturally lower in methionine.



Pistachio Nuts for Erectile Dysfunction

Men eating pistachio nuts experienced a significant improvement in blood flow through the penis accompanied by significantly firmer erections in just three weeks—perhaps due to pistachios’ antioxidant, arginine, and phytosterol content.



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.
