Diet and Hiatal Hernia

Straining at stool over time may force part of the stomach up into the chest, contributing to GERD acid reflux disease. This may explain why hiatal hernia is extremely rare among populations eating high-fiber diets.



Are the Benefits of Organic Food Underrated or Overrated?

If we increased our consumption of conventionally-produced fruits and vegetables, how much cancer would be prevented versus how much cancer might be caused by the additional pesticide exposure?



Estrogen in Meat, Dairy, and Eggs

The sex steroids found naturally in animal products likely exceed the hormonal impacts of endocrine-disrupting chemical pollutants.



Can Diet Protect Against Kidney Cancer?

Plant-based diets appear to protect against renal cell carcinoma both directly and indirectly.



Turmeric Curcumin & Pancreatic Cancer

Carcinogens in grilled and baked chicken may increase the risk of pancreatic cancer, while curcumin, the yellow pigment in the spice turmeric, may sometimes help even in advanced stages of the disease.



Illegal Drugs in Chicken Feathers

By testing chicken feathers for chemical residues, researchers aim to find out what the poultry industry is feeding their birds. The presence of banned drugs and a broad range of pharmaceuticals raises concern, recalling the time in which DES was fed to chickens for years after it was shown to cause human vagina cancer.



Breast Cancer and Constipation

The reason why women who have more frequent bowel movements appear to be at lower risk for breast cancer may be because bile acids absorbed from our intestines concentrate in the breast and have a estrogen-like tumor promoting effect.



From Table to Able: Combating Disabling Diseases with Food

Dr. Greger has scoured the world’s scholarly literature on clinical nutrition and developed this new presentation based on the latest in cutting-edge research exploring the role diet may play in preventing, arresting, and even reversing some of our leading causes of death and disability.



The Best Way to Cook Sweet Potatoes

How does sweet potato baking compare to boiling and steaming, and should we eat the skin?



Cancer Risk from French Fries

The association between cancer and the consumption of deep-fried foods may be due to carcinogens formed at high temperatures in animal foods (heterocyclic amines and polycyclic hydrocarbons) and plant foods (acrylamide).



Treating Asthma and Eczema with Plant-Based Diets

Pilot studies on treating allergic eczema and severe asthma with dietary interventions have shown remarkable results.



How Many Cancers Have Been Caused by Arsenic-Laced Chicken?

Arsenic-containing drugs intentionally added to poultry feed to reduce the parasite burden and pinken the meat are apparently converted by cooking into carcinogenic inorganic arsenic compounds.



Phytates for Rehabilitating Cancer Cells

Unlike most other anticancer agents, the phytates naturally found in whole plant foods may trigger cancer cell differentiation, causing them to revert back to behaving more like normal cells.



Turmeric Curcumin Reprogramming Cancer Cell Death

The spice turmeric appears to be able to switch back on the self-destruct mechanism within cancer cells.



Carcinogen-Blocking Effects of Turmeric

Less than a teaspoon a day of turmeric appears to significantly lower the DNA-mutating ability of cancer-causing substances.



Alkylphenol Endocrine Disruptors and Allergies

The dramatic rise of allergic diseases such as eczema and seasonal allergies may be related to dietary exposure to endocrine-disruptor xenoestrogens, such as alkylphenol industrial pollutants.



Is Liquid-Smoke Flavoring Carcinogenic?

Different brands of liquid smoke flavorings have been tested for DNA-damaging potential, p53 activation, and levels of known carcinogens. Smoked foods such as ham, turkey, barbequed chicken, herring, and salmon were also tested.



Is Caramel Color Carcinogenic?

Concern that one of the most commonly-consumed food colorings may cause cancer has led to changes in soft drink formulation in California.



Eggs, Choline, and Cancer

Choline may be the reason egg consumption is associated with prostate cancer progression and death.



Fukushima & Radioactivity in Seafood

The majority of radioactive fallout from the Fukushima nuclear power plant tragedy was absorbed by the Pacific Ocean. What does that mean for seafood safety?



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.



Prolonged Liver-Function Enhancement from Broccoli

The boost in detoxifying enzymes triggered by cruciferous vegetable consumption may last for weeks!



Cancer, Interrupted: Garlic and Flavonoids

Garlic and flavonoid phytonutrients found in fruits, vegetables, nuts, and grains appear to protect against DNA damage induced by mutagenic chemicals found in cooked meat.



Cancer, Interrupted: Green Tea

Using the cooked meat carcinogen PhIP to turn normal breast cells cancerous, researchers explore the use of green tea to interrupt this malignant transformation.



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.



Miocene Meteorites and Uric Acid

Human beings lost the ability to detoxify uric acid millions of years ago. What implications does this have for our health today?



President’s Cancer Panel Report on Environmental Risk

The official National Cancer Institute report on the “unacceptable” burden of cancer stemming from industrial chemical pollutants is strongly worded, but lacks sufficient dietary guidance.



Eating Green to Prevent Cancer

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



Antimutagenic Activity of Green vs. White Tea

The ability of green versus white tea to protect against in vitro DNA damage caused by a cooked chicken carcinogen (heterocyclic amine).



Chicken Dioxins, Viruses, or Antibiotics?

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.



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.



DNA Protection from Broccoli

Eating broccoli appears to make DNA more resistant to damage.



Meat Additives to Diminish Toxicity

How meat scientists justify their promotion of foods associated with cancer risk.



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.



Vitamin C-Enriched Bacon

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



Carcinogens in the Smell of Frying Bacon

Frying bacon outdoors decreases the concentration of airborne nitrosamine carcinogens.



Prevention Is Better Than Cured Meat

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.
