Pistachos para la disfunción eréctil

En solo tres semanas, hombres que comían pistachos experimentaron una mejora significativa en el flujo de sangre en el pene, acompañado de erecciones más firmes. Tal vez esto sea debido al antioxidante presente en los pistachos, la arginina, y el contenido de fitosteroles.



Prevenir con berros el estrés oxidativo inducido por el ejercicio.

Aquellos que comen dietas más a base de vegetales pueden tener naturalmente un sistema mejorado de defensas antioxidantes, para contrarrestar el daño en el ADN causado por los radicales libres producidos por el ejercicio de alta intensidad.



Reducing Muscle Soreness with Berries

Anti-inflammatory phytonutrients in berries may explain why cherries can speed recovery after a marathon—by reducing muscle pain in long-distance runners.



Reducing Muscle Fatigue with Citrus

Daily citrus fruit consumption during athletic training may reduce muscle fatigue, as evidenced by lower blood lactate concentrations.



Tart Cherries for Insomnia

The melatonin content in certain plant foods such as almonds, raspberries, and goji berries may explain the improvement in sleep quality associated with tart cherry consumption.



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.



Antiangiogénesis: cortar el suministro de los tumores

Las células cancerosas están comúnmente presentes en el cuerpo, pero no pueden crecer y convertirse en tumores si no tienen un suministro sanguíneo. Inhibidores de angiogénesis en los alimentos vegetales plantas pueden prevenir que esto ocurra.



El cáncer de mama y el alcohol, ¿cuánto es seguro?

Casi 5000 muertes por cáncer de mama al año pueden ser atribuidas al consumo leve de alcohol (hasta una sola bebida al día).

Raisins may be preferable to sports supplement jelly beans and commercial energy gels.



Prevenir la enfermedad de Parkinson con la dieta

La existencia de bajos niveles de químicos neurotóxicos en el queso podría explicar la conexión entre el consumo de productos lácteos y la enfermedad de Parkinson.



Preventing Breast Cancer by Any Greens Necessary

Which was associated with lowest breast cancer risk in African-American women? Apples, bananas, broccoli, cabbage, cantaloupe, carrots, collard greens, grapefruit, oranges, spinach, tomatoes, or sweet potatoes?



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.



Los beneficios de las semillas de fenogreco

La especia fenogreco parece mejorar significativamente la fuerza muscular y la capacidad para el levantamiento de pesas, y ha mostrado propiedades anticancerígenas in vitro.



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.



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.



Plant-Based Bodybuilding

Lower levels of the cancer-promoting growth hormone IGF-1 in those eating vegan is not expected to affect their accumulation of muscle mass.



How Plant-Based to Lower IGF-1?

Those eating vegan had significantly lower IGF-1 levels and higher IGF-binding proteins than those just eating vegetarian, suggesting that the more plant-based one’s diet becomes, the lower one’s risk of fueling growth hormone-dependent cancer growth.



The Answer to the Pritikin Puzzle

Lower cancer rates among those eating a plant-based diet may be a result of reduced blood levels of IGF-1, and enhanced production of IGF-1 binding protein.



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.



Is It the Diet, the Exercise, or Both?

Whose blood is better at killing cancer cells? People who eat a standard diet and exercise strenuously, or those who eat a plant-based diet and just exercise moderately?



Slimming the Gecko

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



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?



Arrancar de raíz las principales causas de muerte

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.



What Women Should Eat to Live Longer

A competing risks analysis of the Harvard Nurses’ Health Study compares the danger of smoking cigarettes to the danger of animal product consumption (cholesterol), and the benefits of plant foods (fiber) to the benefits of exercise.



Eating Healthy on the Cheap

Plant-based diets may offer the best investment for dietary health.



Raw Broccoli & Bladder Cancer Survival

The effect of raw and cooked broccoli consumption on survival rates of bladder cancer patients.



Smoking vs. Kale Juice

The effect of kale juice on LDL and HDL cholesterol, and the antioxidant capacity of the blood.



So Should We Drink Beet Juice, or Not?

In the context of a healthy, plant-based diet, the nitrates in vegetables can safely be converted into nitric oxide, which can boost athletic performance, and may help prevent heart disease.



Carcinogens in the Smell of Frying Bacon

Frying bacon outdoors decreases the concentration of airborne nitrosamine carcinogens.



Are Nitrates Pollutants or Nutrients?

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.



Vegetables Rate by Nitrate

If nitrates can boost athletic performance and protect against heart disease, which vegetables have the most—beans, bulb vegetables (like garlic and onions), fruiting vegetables (like eggplant and squash), greens (such as arugula), mushrooms, root vegetables (such as carrots and beets), or stem vegetables (such as celery and rhubarb)?



Hearts Shouldn’t Skip a Beet

The nitrate in vegetables, which the body can turn into the vasodilator nitric oxide, may help explain the role dark green leafy vegetables play in the prevention and treatment of hypertension (high blood pressure) and heart disease.



Asparagus Pee

Young infants, and perhaps those with recurrent oxalate kidney stones, should avoid beets. But most commonly, the chief side effect is beeturia, the harmless passage of pink urine, though not all are affected—akin to the malodorous urine (“stinky pee”) that sometimes results from asparagus consumption.



Out of the Lab Onto the Track

Randomized, double-blind, placebo-controlled, crossover studies convinced the scientific establishment that nitrate-rich vegetables (such as beets) could noticeably improve athletic performance.



Don’t Use Antiseptic Mouthwash

The natural flora on our tongue (lingual bacteria) are essential for the athletic performance-enhancing effect of the nitrates in vegetables such as beetroot.



Priming the Proton Pump

To understand how beets could reduce the oxygen cost of exercise while improving athletic performance, one must review the biochemistry of energy production (ATP synthase), and the body’s conversion of nitrates to nitrites into nitric oxide.



Doping with Beet Juice

Beets found to significantly improve athletic performance while reducing oxygen needs—upsetting a fundamental tenet of sports physiology.
