Meat Fumes: Dietary Secondhand Smoke

The polycyclic aromatic hydrocarbons in the vapors released from cooking meat may be hazardous for fetal development, and increase the risk of cancer.



Heterocyclic Amines in Eggs, Cheese, & Creatine?

Even vegetarians could potentially be exposed to the carcinogens typically formed by cooking meat through eggs, cheese, creatine sports supplements, and cigarette smoke.



Reducing Cancer Risk in Meat-Eaters

Those who eat meat risk food poisoning from undercooked meat, but also exposure to cooked meat carcinogens in well-cooked meat. By boiling meat, non-vegetarians can mediate their risk of both.



PhIP: The Three-Strikes Breast Carcinogen

The cooked meat carcinogen PhIP—found in fried bacon, fish, and chicken—may not only trigger cancer and promote tumor growth, but also increase its metastatic potential, by increasing its invasiveness.



Estrogenic Cooked-Meat Carcinogens

DNA-damaging chemicals, formed when meat is cooked, stimulate breast cancer cells almost as much as pure estrogen, and can infiltrate the ducts where most breast cancers arise.



Fibromyalgia vs. Mostly Raw & Mostly Vegetarian Diets

How plant-based does one’s diet need to be in order to effectively treat fibromyalgia?



Fibromyalgia vs. Vegetarian and Raw Vegan Diets

Plant-based diets may be effective for the treatment of fibromyalgia, a painful condition suffered by millions.



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.



Potassium and Autoimmune Disease

Plant-based diets appear to decrease inflammation via a variety of mechanisms—including boosting our adrenal gland function, due to the consumption of potassium rich foods.



Nonhuman Molecules Lining our Arteries

The foreign meat molecule Neu5Gc builds up in human tumors and atherosclerotic plaques, and may play an inflammatory role in the progression of both diseases.



How Tumors Use Meat to Grow: Xeno-Autoantibodies

Cancer may use a molecule found in animal products to trick our immune system into feeding it with inflammation.



The Inflammatory Meat Molecule Neu5Gc

Plant-based diets may help rheumatoid arthritis by decreasing exposure to an inflammatory compound found in animal products.



Clonal Deletion Theory of Immunity

Plant-based diets may be protective against multiple sclerosis because IGF-1 can prevent our immune system from eliminating autoimmune cells.



Protein and Heart Disease

Why is the intake of animal protein associated with heart disease—even independent of saturated fat—and the intake of plant protein protective?



Lowering Dietary Antibiotic Intake

What a few days eating vegetarian can do to the levels of antibiotics and phthalates flowing through one’s body.



Eating Green to Prevent Cancer

Chlorophyll, the most ubiquitous plant pigment in the world, may protect our DNA against mutation by intercepting carcinogens.



Paleolithic Lessons

An evolutionary argument for a plant-based diet is presented, in contrast to “Paleo” fad diets.



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.



Too Much Soy May Neutralize Benefits

Vegans consuming 7 to 18 servings of soy foods a day may end up with circulating IGF-1 levels comparable to those who eat meat.



Animalistic Plant Proteins

While animal proteins increase levels of the cancer-promoting growth hormone IGF-1, and most plant proteins bring levels down, “high quality” plant proteins, such as soy, may not significantly affect levels in either direction. This, however, may depend on the quantity consumed.



Protein Intake and IGF-1 Production

Animal protein consumption triggers the release of the cancer-promoting growth hormone IGF-1.



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.



Prostate vs. a Plant-Based Diet

Eating a plant-based diet may protect against BPH (benign prostatic hypertrophy, an enlarged prostate).



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?



Ex Vivo Cancer Proliferation Bioassay

Two weeks on a plant-based diet appears to significantly enhance cancer defenses against breast cancer and colon cancer cells. The blood of those eating a vegan diet for a year suppresses cancer cell growth nearly eight times better.



Engineering a Cure

Lifestyle medicine pioneer Nathan Pritikin, who reversed his own heart disease through diet and went on to help millions of others, wasn’t a doctor or dietician, but an engineer.



Slimming the Gecko

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



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.



Biblical Daniel Fast Put to the Test

Within a matter of weeks, participants placed on the vegan diet outlined by the prophet Daniel experienced improvements in blood pressure, cholesterol and insulin levels, insulin resistance, and C-reactive protein levels, a marker of inflammation within the body.



Tightening the Bible Belt

Researchers set out to replicate the “Daniel Fast”—the biblical nutrition trial outlined in Daniel 1:8-16.



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.



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.



The Best Way to Boost Serotonin

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.



Mineral of the Year—Magnesium

Despite promising autopsy and population data suggesting that inadequate magnesium intake is a risk factor for sudden cardiac death, it wasn’t until recently that this was demonstrated in prospective studies.



Uprooting the Leading Causes of Death

Death in America is largely a foodborne illness. Focusing on studies published just over the last year in peer-reviewed scientific medical journals, Dr. Greger offers practical advice on how best to feed ourselves and our families to prevent, treat, and even reverse many of the top 15 killers in the United States.



The Benefits of Caloric Restriction Without the Actual Restricting

One mechanism by which caloric restriction may extend one’s lifespan is by upregulating dehydroepiandrosterone (DHEA), the most abundant steroid hormone in the human body. DHEA supplements are discouraged, but there may be a natural way to conserve levels as we age.
