Analysing 5,350 Whitehall II participants over an average 16 years, researchers found those eating a Western-type diet heavy in red and processed meat, whole dairy and fried food more likely to die early and to develop heart disease, stroke, cancer and mental health disorders.

Eating meat boosts premature death risk
Across two studies of 37,698 men and 83,644 women followed 22 to 28 years, with 23,926 deaths, a daily three-ounce serving of unprocessed red meat was tied to 13% higher mortality and processed meat to 20%. Swapping in poultry, nuts or legumes lowered risk up to 19%.

Beef, spam and sausage boost prostate cancer risk
The piece cautions that one Illinois man's recovery after proton therapy proves nothing, since many prostate cancers progress slowly and patients often survive untreated. It notes screening is not advised past age 70, because aggressive follow-up can do more harm, including loss of sexual function.

Cancer News: Meat consumption boosts risk of colorectal cancer - study
Among 17,072 screening-trial participants, 1,008 of whom developed distal colorectal adenoma, the highest intakes of grilled meat, well-done meat and meat-derived mutagens matched 53 to 75 percent higher risk of rectal tumors. The highest dietary or supplemental iron intake ran the other way.
Food
Meat ups cancer risk while fruit/vegetables reduce it
A translated compilation of older claims linking meat to cancer, including a 1976 Senate committee report and National Research Council figures attributing 40% of cancers in men and 60% in women to meat. The piece notes names and organizations may not be rendered accurately.
Food
Meat, vegetable oils may boost risk of inflammatory bowel disease
Vibeke Andersen's review ties diets high in protein, particularly animal protein, to more inflammatory bowel disease and relapses, and finds omega-6 fats from corn and soybean oil may predispose to ulcerative colitis while fish-derived DHA and EPA may protect.
Food
Meats cooked at high temperature boost prostate cancer risk
Comparing 726 prostate cancer patients with 527 men without it, researchers linked hamburgers, processed meat, grilled red meat and well-done red meat to 79, 57, 63 and 52 percent higher risk of advanced, but not localized, disease. White meat showed no association.

Meat, dairy products, sugar may up breast cancer risk - studies
Two studies tie insulin-like growth factor I to breast cancer: French researchers measured higher average serum IGF-I in 44 patients than in 92 controls, 26 versus 20 ng/ml, and a second found top-quartile women 92 percent more likely to be diagnosed, an association seen only in Caucasian women.

Pancreatic cancer, linked to dietary habits, grows slowly - studies
Johns Hopkins researchers modelling mutations from patients who died of pancreatic cancer estimate about 11.7 years for the first cancer cell to arise in a high-grade lesion, 6.8 more years before spread, and 2.7 years to death, leaving a window for earlier detection.
Obesity
Meat Linked to Obesity
An American Journal of Clinical Nutrition study followed some 374,000 adults in nine European countries for five years and found 250 grams of meat a day tracked with about 2 kg of weight gain. Red meat, poultry and processed meat all showed positive associations.
Food
Processed meat linked to elevated risk of heart disease, diabetes
A Harvard meta-analysis in Circulation linked each 50 grams of processed meat eaten daily, about one hot dog, with 42 percent higher heart disease risk and 19 percent higher diabetes risk. Unprocessed meats showed no such link, and researchers suspect the salt and nitrate preservatives.
Chemical
Well-done meat does not raise breast cancer risk
Analyzing Nurses' Health Study data on cooking methods, Wu K and colleagues found meat-derived heterocyclic amines showed no association with postmenopausal breast cancer; high MeIQx, PhIP and DiMeIQx intakes tracked with slightly less ER-negative disease.
Nutrition
Too much meat not good for bone health in pre-pubertal girls
Following 757 pre-pubertal Beijing girls for five years, researchers found calcium intake tracked with higher bone mineral content while protein intake tracked with lower, and animal protein, particularly meat protein, showed significant negative effects at the forearms.

Red Meat, Processed Meats May Raise Prostate Cancer Risk
Following 174,343 US men for nine years, National Cancer Institute researchers recorded 10,313 prostate cancers and found the highest red meat intake carried 12 percent more total risk and 31 percent more advanced disease. Nitrite and nitrate tracked with 24 and 31 percent higher risk.
