B. Melnik reports that acne is far less common among people eating a low-glycaemic palaeolithic diet without dairy, that two randomized trials support low-glycaemic-load diets as treatment, and that milk appears to drive acne through mTORC1 signalling.

Two servings of salmon a week is healthy for pregnant women and their babies (PR)
University of Granada researchers report that pregnant women with low fish intake who ate two weekly servings of farmed, omega-3-enriched salmon from 20 weeks' gestation raised omega-3 levels and antioxidant defences in both mother and child.

Dairy Products Do Not Promote Bone Health
Tracking adolescent girls for seven years, researchers found no protection against stress fractures from dairy or calcium. Among girls exercising more than an hour a day, the highest calcium intakes came with more than double the fracture risk. Vitamin D did help: the highest intakes halved it.

Why are Kids Getting Pink Slime for Lunches?
Mercola reports that the USDA ordered 7 million pounds of 'lean beef trimmings' for school lunches, a mix of ammonia-treated beef scraps and connective tissue. He says the filler can legally make up 15 percent of a beef product without appearing on the label.

Men eating fatty diet may be less fertile
Among 99 US men, those eating the most total fat had 43 percent lower total sperm counts and 38 percent lower sperm concentrations than those eating the least, a Human Reproduction study found. Saturated fat showed a similar pattern, while high omega-3 intake tracked slightly higher counts.

People eating red meat more likely to die earlier
Harvard researchers following 37,698 men and 83,644 women found one daily serving of unprocessed red meat linked to a 13 percent higher risk of premature death and processed red meat to 20 percent, with cardiovascular death risk up 18 and 21 percent respectively.

Solid evidence: Drinking regular cola likely boosts heart disease risk
Over six months, 47 overweight adults drank a liter a day of regular cola, milk, diet cola or water. The cola group ended with far more liver, muscle and visceral fat and higher triglycerides and cholesterol than at baseline, while milk and diet cola lowered systolic blood pressure.

Canola oil may harm the heart and kidney?
Rats fed a diet with 10 percent canola oil for 10 weeks had much higher systolic blood pressure than rats fed soybean oil, a Japanese study found. By 26 weeks their hearts and kidneys tended to be heavier with sporadic lesions, and plasma lipids and neutrophil counts had risen.

Eating Canned Food Shown to be Linked to Heart Disease
New data from a long-running British health survey link high urinary BPA to increased heart disease risk, which the piece stresses is not proof of cause. One study found eating canned goods raised participants' urinary BPA concentrations by more than 1,000 percent.

Processed meat like SPAM linked to high diabetes risk- study
In the Strong Heart Family Study of American Indians followed five years, those eating the most processed meat faced 63 percent higher diabetes risk, and the heaviest SPAM eaters double the risk. Unprocessed red meat showed no link, and results may not carry to other populations.

Red meat, processed meat up pancreatic cancer risk
A British Journal of Cancer meta-analysis of eleven prospective studies and 6,643 cases found each additional 120 grams of red meat a day was linked to a 13 percent higher pancreatic cancer risk, 29 percent in men and no association in women, and 50 grams of processed meat to 19 percent.

Red meat linked to metabolic syndrome, type 2 diabetes and cardiovascular disease
In the Multi-Ethnic Study of Atherosclerosis, people with the highest intakes of heme iron and zinc from red meat were 25 and 29 percent more likely to develop metabolic syndrome, while high vitamin E intake ran the other way. The article stresses this was not a trial, so cause remains unproven.

Red Meat Increases Risk of Dying
Harvard researchers followed 121,342 people for up to 28 years and found each daily serving of red meat raised the risk of dying by 12%, and each serving of processed meat by 20%. An accompanying editorial argued cutting back would also lower costs and environmental impact.

Eating oranges may lower stroke risk in women
Following about 70,000 women in the Nurses' Health Study for 14 years, researchers linked citrus flavanones such as naringenin and hesperetin to lower risk of ischemic stroke. They advise eating whole fruit rather than juice or supplements; vitamin C itself showed no link to stroke risk.

Walnuts may help fight cancer
Mice with prostate tumours fed three ounces of walnuts a day had tumours shrink by 50 percent and growth slow by 30 percent against controls. Lead researcher Paul Davis says further research is needed to learn whether walnuts have the same effect in men.

Monitoring the Population's Food and Supplement Intakes
USDA's Agricultural Research Service released 'Total Nutrient Intakes' tables that combine what national survey participants eat with what they take as supplements. Among adults 20 and older, 48 percent of women and 38 percent of men report using dietary supplements.

Almost Everyone Eats it, But it's a "Breeding Ground" for Disease
Dr. Robert Lustig argues in Nature that sugar is a poison behind obesity and chronic disease. Dr. Mercola adds that fructose can activate taste cells on the pancreas and that glycation damages the body, and recommends holding total fructose below 25 grams a day.

Soft drinks boost deadly pancreatic cancer risk
Pooling 14 prospective cohorts covering 853,894 people and 2,185 pancreatic cancer cases, researchers found drinking sugar-sweetened carbonated soft drinks was tied to a moderate but significant rise in risk. Coffee and tea showed no association with the disease.
