Do Walnuts Really Improve Artery Function?
nutritionfacts.org

Good news for nut lovers: Eating at least one serving of walnuts per week may drop our chances of a cardiovascular-related death by 50%. However, walnut consumption may only drop our cholesterol levels about 5%. How could we get a 50% drop in cardiac mortality from just a 5% drop in cholesterol? Walnuts must have […]

Dr. Greger Takes on Smoothies in New DVD
nutritionfacts.org

Smoothies have been one of the most requested topics, but for years there seemed to be little pertinent research. I was surprised when I reprised my search this year to find hundreds of studies, so it’s smoothie-time! I rarely do such long contiguous video series any more, but I had neglected the topic for so […]

Three Brands of Nutritional Yeast Contain Detectable Lead Levels But the Risk is Minimal
nutritionfacts.org

Note from Dr. Greger: In short, we found detectable amounts of lead in samples of Frontier, KAL, and Whole Foods brand nutritional yeast, but the lead levels were so low that they all comply with the exceedingly (and justifiably) strict California Prop 65 standards. Still, I advise pregnant women who eat more than a third […]

Dioxins Stored in Our Own Fat May Increase Diabetes Risk
nutritionfacts.org

Finding higher diabetes rates among those heavily exposed to toxic pollutants—such as those exposed to Agent Orange, chemical plant explosions, toxic waste dumps, or heavy metals in fish from the Great Lakes—is one thing. Would the same link be found in a random sampling of the general population? Yes. A strong dose-dependent relationship was found […]

Why Deep Fried Foods May Cause Cancer
nutritionfacts.org

In the latest study on dietary patterns and breast cancer risk among women, healthier eating was associated with eliminating three-quarters of the odds of breast cancer, whereas less healthy eating was associated with up to nearly eight times the odds. Included in the unhealthy eating pattern was the consumption of deep-fried foods, which have previously […]

Do Cholesterol Statin Drugs Cause Breast Cancer?
nutritionfacts.org

What does breast cancer have to do with cholesterol? There are many potential mechanisms by which cholesterol boosts breast cancer growth. For example, our bodies make estrogen, which is correlated with an increased risk of breast cancer, out of cholesterol. We also package cholesterol into LDL, which, as you can see in my video Cholesterol […]

Using Diet to Treat Asthma and Eczema
nutritionfacts.org

I previously discussed the power of fruits and vegetables to help prevent and treat asthma and allergies. If adding a few more servings of fruits and vegetables may help asthma, what about a diet centered around plants? Twenty patients with allergic eczema were placed on a vegetarian diet.  At the end of two months, their […]

Treating Asthma With Plants vs. Pills
nutritionfacts.org

In my video Treating Asthma With Fruits and Vegetables, I highlighted a landmark study on manipulating antioxidant intake in asthma. The study found that just a few extra fruits and vegetables a day can powerfully reduce asthma exacerbation rates. If the antioxidants in the plants are ameliorating asthma, then why can’t we take antioxidant pills […]

Researchers speculated “over a decade ago that […]

How Fruits and Vegetables Can Prevent Asthma
nutritionfacts.org

Asthma is the most common chronic disease in children and the prevalence is increasing around the world. Despite this, most research dollars are spent on adult chronic disease. “One might ask,” a group of researchers posited “whether this is because our politicians and senior administrators feel themselves to be more likely to suffer from the […]

Our Tax Dollars Subsidize Unhealthy Foods
nutritionfacts.org

Why do food companies sell junk? Because unhealthy commodities are highly profitable. This is in part because of their “low production cost, long shelf-life, and high retail value,” which create perverse incentives for industries to market and sell more junk. In a study highlighted in my video, Taxpayer Subsidies for Unhealthy Foods, researchers at the […]

Living Longer by Reducing Leucine Intake

Many studies have shown that calorie restriction, without malnutrition, can increase lifespan and lower the risk of age-related diseases, such as cancer. However, for many people, calorie restriction clearly has its drawbacks. In the classic Minnesota Starvation Study, many of the volunteers suffered a preoccupation with food, constant hunger, binge eating, and lots of emotional […]

Exploiting Autophagy to Live Longer

Thanks to advances in modern medicine, we are living longer lives, but we’re doing it by lengthening the morbidity phase. In other words, we live longer, but sicker, lives (see my video: Americans Are Live Longer, but Sicker Lives). So, traditional medicine increases the number of old people in bad health. Ideally, though, we’d extend lifespan […]
