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.

A dramatic difference exists between the anti-inflammatory and antioxidant effects of black walnuts versus English walnuts.
The secret to naturally boosting serotonin levels in the brain may include eating foods such as pumpkin seeds, with a high tryptophan-to-total protein ratio. This may help explain why studies show that those eating plant-based diets have superior mood states.
Contrary to popular belief, the consumption of animal foods may actually decrease tryptophan levels in the brain. Carbohydrates, on the other hand, can boost transport across the blood-brain barrier, which has been used to explain premenstrual cravings.
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.
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 whole grain phytonutrient phytic acid (phytate) partially inhibits mineral absorption, but has a wide range of health-promoting properties, such as anticancer activity. By concurrently eating mineral absorption enhancers, such as garlic and onions, one can get the best of both worlds by improving the bioavailability of iron and zinc in plant foods.
Not only do plant-based diets appear to prevent kidney function decline, they may also be used to treat kidney failure. Even at the same protein loads, the body is able to better handle phosphorus excretion from plant-based diets, reducing the risk of metastatic calcification.
Given how vascular our kidneys are, it should comes as no surprise that animal protein, animal fat, and cholesterol are associated with declining kidney function (microalbuminurea—loss of protein in the urine), which can be an early warning sign not only for kidney failure, but also for heart disease and a shortened lifespan.
The high bacteria load in raw or cooked animal foods and fermented foods may trigger an endotoxemic surge of inflammation, which may be exacerbated by the presence of saturated animal fat.
The endotoxemia (bacterial toxins in the bloodstream) that follows a meal of animal products and results in inflammation and stiffened arteries may come from the food itself, rather than from one’s own gut bacteria.
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.
La carne (incluyendo la de pescado), el queso, y la ingesta de proteínas animales en general se han asociado con un mayor riesgo de enfermedad intestinal inflamatoria (EII). Al mismo tiempo, las dietas basadas en vegetales no sólo pueden ayudar a prevenir tales condiciones, sino también a tratarlas, lo que resulta en las tasas de remisión más elevadas registradas para la enfermedad de Crohn.
By preventing the buildup of cholesterol in our bloodstream, we can prevent atherosclerosis in our coronary arteries—the leading cause of death in the United States for both men and women. This involves increasing our intake of fiber-containing plant foods, and decreasing our intake of trans fat, saturated fat, and cholesterol found in junk food and animal products.
The fish and poultry industries propose moving from a zero tolerance policy on certain dangerous foodborne pathogens to an “acceptable risk” policy—given how widely contaminated their products are with potentially deadly fecal bacteria.
In a national survey, fewer than half of the participants realized meat contaminated with fecal food-poisoning bacteria, such as Salmonella, can still legally be sold. Rather than producing safe products, the meat industry shifts the responsibility for safety onto the consumer.
Given their inherent resistance to food-poisoning bacteria, maggots can be used to create an antibacterial food additive to increase the safety of the meat supply.
Bacteria-eating viruses (bacteriophages) have been approved as meat additives to reduce the risk of Listeria and Campylobacter found in processed meat and poultry products, but there’s a concern they could spread toxin genes between bacteria.
Risk of developing cataracts was compared in meat-eaters, fish-eaters, vegetarians, and vegans.
A healthy diet may not only prevent the complications of diabetes, but also reduce the risk of age-related macular degeneration—another common cause of blindness.
Vegetarians appear to get more of a cognitive boost than meat-eaters from creatine supplementation.
There are rare birth defects in which the inability to produce certain compounds requires an exogenous source. Presented here is a case report of a boy with a mutation in his carnitine transport system.
Plant-based diets may offer the best investment for dietary health.
Dietary interventions, including increasing fruit and vegetable intake and decreasing meat intake, may not only help slow the progression of chronic obstructive pulmonary disease, but may actually improve lung function.
Chronic obstructive pulmonary disease is now the third leading cause of death. The good news is that. in addition to smoking cessation, there are dietary interventions that can help prevent COPD.
Exposure to meat packaging in the supermarket may lead to food poisoning in children placed in shopping carts.
The food-poisoning fecal bacteria found in 70% of U.S. retail poultry is destroyed by proper cooking, but contamination of the kitchen environment may place consumers at risk.
A neuropathic strain of the fecal bacteria Campylobacter, found in poultry, can trigger Guillain-Barré syndrome, a rapid and life-threatening paralysis.
Poultry workers exhibit an excess of a wide range of diseases, from thyroid conditions to schizophrenia, and autoimmune neurological disorders, such as myasthenia gravis. This may be due to exposure to viruses present in chickens and turkeys.
Avian leukosis/sarcoma virus has been found in 14% of retail egg samples.
The largest study to date on poultry workers found a significantly increased risk of dying from penile cancer, thought to be due to exposure to oncogenic (cancer-causing) chicken viruses, which raise consumer concerns as well.
The association between poultry and cancer may be explained by the presence in chickens’ and turkeys’ flesh of industrial carcinogens such as dioxins, oncogenic (cancer-causing) viruses, and/or the drugs that were fed to the birds.
In a study of a half million people, which was most associated with the risk of developing lymphoma? Red meat, processed meat, poultry, offal, eggs, or milk?
Even after controlling for a variety of dietary and nondietary factors, those eating plant-based diets appear to have lower overall cancer rates.
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.
Monday, March 12, 2012: The Harvard Health Professionals Follow-up Study and the Harvard Nurses’ Health Study concluded that red meat consumption was associated with living a significantly shorter life—increased cancer mortality, increased heart disease mortality, and increased overall mortality.
How meat scientists justify their promotion of foods associated with cancer risk.
The addition of vitamin C to processed (cured) meats such as bacon may actually make them more carcinogenic.
The levels of nitrosamines—considered the most carcinogenic agents in cigarette smoke—were recently measured in an array of processed meats including chicken, turkey, and pork.
Phytonutrients, such as vitamin C, prevent the formation of nitrosamines from nitrites—which explains why adding nitrite preservatives to processed meat can be harmful, but adding more vegetables, with their nitrite-forming nitrates, to our diet can be helpful.
