Autopsy of Chicken Nuggets

If the bulk of fast food chicken nuggets is not actually chicken meat, what’s in them?



One in a Thousand: Ending the Heart Disease Epidemic

Many of our most common diseases found to be rare, or even nonexistent, among populations eating plant-based diets.



Are Sugary Foods Addictive?

Evidence from PET scans suggests brain activity changes from the overconsumption of sugar may parallel that of drug addiction. Diminished “pleasure center” dopamine pathway sensitivity in obese individuals may be analogous to that found in cocaine addicts and alcoholics.



Medicina del estilo de vida: tratar las causas de la enfermedad

Si los médicos pueden eliminar algunos de nuestros principales asesinos al tratar las causas subyacentes de la enfermedad crónica de mejor forma que casi cualquier otra intervención médica, ¿por qué no lo hacen más médicos?



Tell Your Doctor if You Eat Grapefruit

The role white and pink (red) grapefruit may play in weight loss and cholesterol control, as well as the suppression of drug-clearance enzymes within the body.



La enfermedad cardiaca empieza en la niñez

Antes de los diez años, casi todos los niños tienen líneas de grasa en sus arterias. Este es el primer signo de ateroesclerosis, la principal causa de muerte en los Estados Unidos. Así que, el interrogante, para la mayoría de nosotros, no es si deberíamos comer sano para prevenir la enfermedad cardiaca, sino si queremos revertir la enfermedad cardiaca que probablemente ya tenemos.



Changing Our Taste Buds

Within a few weeks of eating healthier, our taste sensations change such that foods with lower salt, sugar, and fat content actually taste better.



Tricks to Get Adults to Eat Healthier

Changing food perceptions and incorporating puréed vegetables into entrees can improve the dietary quality of kids and grown-ups.



Tricks to Get Kids to Eat Healthier at School

Interventions to improve child nutrition at school have included everything from reducing cookie size, adding fruit to classroom cupcake celebrations, and giving vegetables attractive names, to more comprehensive strategies such as “veggiecation” curricula, and transforming school cafeterias.



Más de una manzana al día para prevenir nuestras enfermedades más comunes

El Dr. Greger ha examinado minuciosamente la literatura académica mundial sobre nutrición clínica y creó esta nueva presentación en vivo sobre lo más reciente en investigación de vanguardia acerca de cómo una alimentación sana puede influir en algunas de nuestras condiciones médicas más comunes.



Male Fertility & Diet

Dioxins, endocrine disrupting pollutants, heavy metals, saturated fat, and steroids in the meat supply may be affecting sperm counts, semen quality, and the ability of men to conceive.



Black Raspberries vs. Oral Cancer

Black raspberries may cause complete clinical regression of precancerous oral lesions (oral intraepithelial neoplasia).



Carnitina, colina, cáncer, y colesterol: la conexión OTMA

Ampliando la temática de mi próxima participación en “El Show del Dr. Oz”, un nuevo artículo hito en el New England Journal of Medicine muestra que la colina en huevos, carne de ave, lácteos, y carne de pez produce el mismo OTMA tóxico que la carnitina en la carne roja, lo que puede ayudar a explicar la protección que proporciona una dieta basada en plantas ante enfermedades cardíacas y cáncer de próstata.



Do Fruit & Nut Bars Cause Weight Gain?

Despite the caloric density of both nuts and dried fruit, they do not appear to lead to the expected weight gain.



Flesh and Fructose

Meat and sugar increase uric acid levels, which are associated with increased risk of gout, hypertension (high blood pressure), obesity, prediabetes, diabetes, kidney disease and cardiovascular disease.



Whole Grains May Work as Well as Drugs

The consumption of three portions of whole grains a day appears as powerful as high blood pressure medications in alleviating hypertension.



Metabolic Syndrome and Plant-Based Diets

Plant-based diets appear to protect against metabolic syndrome, also known as syndrome X, which is characterized by the so-called “deadly quartet”—abdominal obesity, high fasting sugars, high triglycerides, and high blood pressure.



Unsweetening the Diet

All sweeteners—natural and artificial; caloric and non-caloric—help maintain cravings for intensely sweet foods.



Neurobiology of Artificial Sweeteners

The disconnect between sweetness sensations coming from our tongue, and the lack of a caloric feedback loop in the gut, may result in overeating.



How Diet Soda Could Make Us Gain Weight

People consuming low-calorie sweeteners may overcompensate by eating more than they otherwise would.



Standing Up for Your Health

Prolonged daily sitting is associated with a shorter lifespan, even in those who exercise regularly. Standing and treadmill desks are two potential solutions for office workers.



The Best Baby Formula

Exclusive breastfeeding for a full six months may, ironically, improve our children’s taste for vegetables—whereas children fed formula grow up with increased rates of inflammatory diseases such as asthma, cancer, and diabetes.



Modern Meat Not Ahead of the Game

Since chronic inflammation underlines many disease processes, and saturated fat appears to facilitate the endotoxic inflammatory reaction to animal products, researchers have looked to wild animals for less unhealthy meat options.



Próstata versus una dieta basada en vegetales

Todos los varones deberían considerar comer una dieta sana para la próstata, que incluye legumbres (alubias, guisantes, lentejas, soja); ciertas verduras (como ajos y cebollas); ciertas semillas (semillas de lino); y evitar granos refinados, huevos, y productos avícolas.



Slimming the Gecko

A workplace dietary intervention study at GEICO corporate headquarters demonstrates the power of plant-based eating.



To Snack or Not to Snack?

A review of the best available science examining the impact of eating frequency on both weight and health.



Diet Pills Do Fat a Lot of Good

Common slimming supplements are found to be ineffective, whereas a diet centered on whole plant foods is described as perhaps the safest approach to weight control.



Circunferencia de la cintura menor que la mitad de tu altura

Las proporción cintura-altura puede ser un mejor indicador de enfermedad que el índice de masa corporal.



Cattlemen’s Association Has Beef with Study

Meat consumption is not only associated with weight gain, but specifically abdominal obesity, which is the most metabolically concerning.



Meat and Weight Gain in the PANACEA Study

In one of the largest nutrition studies ever, total meat consumption was significantly associated with weight gain in men and women—and the link remained even after controlling for calories.



Diet vs. Exercise for Weight Loss

When asked whether food and beverage consumption, or physical activity, was more important, the majority of people get the answer wrong.



The Ice Diet

The water content of plant foods may help explain why those eating plant-based diets are, on average, so slim. Can ice be thought of as having even “fewer” calories than water, since the body has to warm it up?



Tipping Firmicutes to Bacteroidetes

Certain phytonutrients may tip the balance of healthy gut bacteria in favor of flora associated with improved weight control.



Boosting Good Bacteria in the Colon Without Probiotics

Certain good bacteria in our gut can turn the fiber we eat into an anti-inflammatory, anti-cancer compound—called butyrate—that we absorb back into our system. We may be able to boost the number of butyrate-producing bacteria by eating a plant-based diet.



Fawning over Flora

The good bacteria in our gut can digest the fiber we eat, and turn it into an anti-obesity compound—called propionate—that we absorb back into our system.



Fat Burning via Flavonoids

Flavonoid phytonutrients (found concentrated in citrus, berries, red onions, beans, green tea, grapes, and cocoa) may boost metabolism enough to significantly slim one’s waistline.



Fat Burning Via Arginine

The arginine content of nuts may explain their metabolism-boosting effects—though, in a list of the top food sources of arginine, nuts don’t even make the top ten.



Testing the Fat-Burning Theory

Finally, there’s a solution to the mystery of why nuts don’t seem to make people gain weight. It appears to be a combination of factors—including a boost to our metabolism, which results in us burning more of our own fat stores.



Testing the Dietary Compensation Theory

An elegant study is presented, testing the appetite-suppressing effects of walnuts.



Testing the Pistachio Principle

If the fecal fat losses associated with undigested pieces of nuts (due to inadequate chewing), and the tedium of shelling them in the first place, help account for why nuts don’t tend to lead to weight gain, then studies on nut butters would presumably turn out differently.
