A World Journal of Gastroenterology commentary by Clouatre and Preuss argues that hydroxycitric acid, found in the weight-loss supplement Garcinia cambogia, does not promote inflammation or liver toxicity. An editor's note urges caution about sellers' third-party testing claims.

Obesity
Katie Couric-narrated Documentary Fed Up Exposes Causes of US Obesity
The documentary Fed Up, directed by Stephanie Soechtig and narrated by Katie Couric, argues that federal deference to the food industry — from the fight over the 1977 McGovern Report to pressure on WHO in 2006 — pushed low-fat, sugar-heavy products and worsened youth obesity.
Cancer
Milk, cheese, but not yogurt linked to liver cancer
In an EPIC cohort of 477,206 adults followed about 11 years, the highest consumers of total dairy, milk and cheese were 66%, 51% and 56% more likely to develop liver cancer than the lowest. Yogurt showed no association, nor did the same nutrients from non-dairy sources.
Obesity
Raspberry ketone new weight loss dietary supplement
Rodents fed a high-fat diet with raspberry ketone gained less weight in the body, liver and visceral fat, and the compound increased norepinephrine-induced lipolysis in fat cells. The study tested prevention of weight gain, not weight loss.
Obesity
Information Technology, Social Support Help Weight Loss
MU researcher Cheryl Shigaki found information technology such as smartphone apps helps dieters fold healthy changes into daily life by repackaging traditional strategies as exercise logs and nutrition databases. Social and informational support still matter to success, she says.
Diabetes
Coffee lowers risk of type 2 diabetes mellitus
A Diabetes Care meta-analysis pooling 1,109,272 participants found each extra daily cup of caffeinated coffee linked to 9 percent lower type 2 diabetes risk, decaf to 6 percent, and six cups to 33 percent. The authors stress this is a correlation; no trial has shown coffee causes the drop.
Cancer
Genes Elevate Existing Risk Associated with Processed Meat and Cancer
Pooling 9,287 colorectal cancer cases and 9,120 controls from 10 studies, researchers found risk rose 15% with red meat and 11% with processed meat, climbing to 20% and 39% in carriers of two genetic variants. Fruit, vegetables and fiber tracked with lower risk.
Cancer
High sexual activity linked to high prostate cancer risk - study
A meta-analysis by Dennis and Dawson in Epidemiology found men with a history of sexually transmitted infection were 40% more likely to develop prostate cancer, and those who had syphilis 130% more likely. Frequent sexual activity carried 20% higher risk.
Obesity
Weight loss supplement synephrine does not increase blood pressure
In a crossover trial of 10 healthy adults, the multi-ingredient supplement Xenadrine EFX raised systolic and diastolic blood pressure while Advantra Z, carrying eight times more synephrine, did not. The authors attribute the effect to caffeine and other stimulants.
Obesity
Dietary supplements enlisted to fight obesity
A bare list of supplements and other approaches used against obesity, from caffeine, ephedrine, green tea catechins and conjugated linoleic acid to chitosan and chromium picolinate, alongside non-supplement methods such as jaw wiring, hypnosis and acupuncture.
Cancer
Vitamin D may indeed prevent breast cancer?
In a case-control study of 707 postmenopausal breast cancer patients and matched controls, each 20 ng/mL rise in plasma 25(OH)D3 was tied to 72 percent lower breast cancer risk among white women. The association did not hold in the other race and ethnic groups studied.
Diabetes
Type 2 diabetes mellitus risk lower in those eating fruit, vegetables
Among 2,332 Finnish men followed 19 years, those in the highest quartile of fruit, berry and vegetable intake were 24 percent less likely to develop type 2 diabetes, and the highest berry intake carried 35 percent lower risk. No significant association appeared for fruit, juices or vegetables alone.
Diabetes
Diabetes Rates Increasing
Diagnosed diabetes among US adults rose 69 percent over 20 years while undiagnosed cases fell, suggesting better screening, according to an Annals of Internal Medicine analysis of national survey data. Many patients, especially blacks and Mexican Americans, still lack glucose control.
Heart & Blood
Vegetarians and Vegans Have Lower Risk of Heart Disease
Among 592 African-American participants in Adventist Health Study-2, those eating a vegetarian or vegan diet had lower blood pressure, half the diabetes risk and 44% lower hypertension risk than pesco- and non-vegetarians, and were 43% less likely to be obese than non-vegetarians.
Cancer
A High-Fat Diet Increases Risk of Breast Cancer
Analysing 11.5 years of diet records from 337,327 women in the EPIC-Oxford study, researchers found those eating the most fat had a 20 percent higher risk of ER- and PR-positive breast cancer, and those eating the most saturated fat a 28 percent higher risk than the lowest consumers.
Diabetes
Red meat, particularly processed red meat raises risk of type 2 diabetes mellitus
An Pan and Frank Hu write in Future Medicine that the evidence tying higher red meat consumption to type 2 diabetes is convincing, and recommend limiting red meat, especially processed, in favour of vegetables, legumes, nuts, whole grains, low-fat dairy, fish and poultry.
Heart & Blood
Added sugar linked to cardiovascular disease death
In NHANES data with 15-year follow-up and 831 cardiovascular deaths, adults in the highest fifth of added sugar intake were 103 percent more likely to die of cardiovascular disease after adjustment than those in the lowest fifth, a JAMA Internal Medicine study reports.
Diabetes
Meat-Eating is a Risk Factor for Developing Diabetes
A JAMA Internal Medicine review of 39 studies found vegetarian diets were associated with lower systolic and diastolic blood pressure than omnivorous diets, which the authors say supports a dietary approach to preventing hypertension.
