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.



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.



Solving the Mystery of the Missing Calories

A few theories have been proposed as to why nuts don’t appear to contribute to weight gain, including the “pistachio principle” and the fecal excretion theory.

La muerte en los EE. UU. es, en gran medida, una enfermedad alimentaria. El Dr. Greger, enfocándose en estudios publicados durante el año anterior, en revistas médicas revisadas por pares, ofrece recomendaciones prácticas sobre cómo alimentarnos nosotros mismos y a nuestras familias, para prevenir, tratar e incluso revertir muchas de las 15 principales causas de muerte en los Estados Unidos.



The Leaky Gut Theory of Why Animal Products Cause Inflammation

A single meal of meats, eggs, and dairy can cause a spike of inflammation within hours that can stiffen one’s arteries. Originally, this was thought to be the result of saturated animal fat causing our gut lining to leak bacterial toxins into our bloodstream, leading to endotoxemia.



Raw Veggies vs. Cooked for Heart Disease

Fruit and vegetable consumption is associated with a lower risk of heart disease. But which is more protective—raw or cooked?



Breast Cancer Survival and Trans Fat

Breast cancer survivors may reduce their chances of survival if they eat too much trans fat, found primarily in the American diet in junk food and animal products.



Breast Cancer Survival, Butterfat, & Chicken

Breast cancer survivors may reduce their chances of survival if they eat too much saturated fat, found primarily in the American diet in cheese, chicken, and junk food.



Vitamin C-Enriched Bacon

The addition of vitamin C to processed (cured) meats such as bacon may actually make them more carcinogenic.



Plant-Based Atkins Diet

Harvard study found that men and women eating low carb diets live significantly shorter lives, but what about the “eco-Atkins diet,” a plant-based, low carbohydrate diet?



Plant Protein Preferable

Since foods are a package deal, Dr. Walter Willet, the Chair of Harvard’s nutrition department, recommends we emphasize plant sources of protein, rather than animal sources.



Are Avocados Health-Promoting?

Persin, a natural toxin found in avocados, appears so effective at killing breast cancer cells that it is being considered as a chemotherapy agent.
