Blueberry lowers blood pressure
Rats fed a high-fat, high-cholesterol diet plus a blueberry supplement cut their systolic blood pressure by 11 and 14 percent at weeks 8 and 10 compared with rats on the diet alone, and showed better endothelial function.

Pomegranate juice may prevent advanced breast cancer
Working in two breast cancer cell lines, UC Riverside researchers found pomegranate juice and its components luteolin, ellagic acid and punicic acid slowed cancer cell growth and migration and increased cell adhesion, without affecting healthy cells.

Green tea may reduce hypertension induced cognitive impairment
Mao-Hsien Wang and colleagues in Taiwan gave the green tea catechin EGCG to spontaneously hypertensive rats and report that it lowered blood pressure, curbed the rise in locomotor activity, improved water-maze learning and memory, and reduced lipid peroxide production.

Eating allium vegetables cuts cancer risk
Analyzing Italian and Swiss case-control data, researchers found people eating the most onion and garlic had lower odds of several cancers, including 84% and 39% lower for oral and pharyngeal cancer and 88% and 57% lower for esophageal cancer.

Eating soy food may help prevent breast cancer - study
A meta-analysis of 28 studies tied high soy intake to 14% lower breast cancer risk overall, but the protection showed up only in case-control studies, only in Asian countries, and only among postmenopausal women.

Drinking green tea helps prevent bladder cancer
A meta-analysis of 17 case-control and cohort studies found people with the highest green tea intake were 19% less likely to be diagnosed with bladder cancer than those with the lowest. The authors say the protection appears in Asian populations.

Chocolate helps prevent heart failure?
The study suggests eating one to three servings of chocolate a month may lower heart failure risk, but it was not a trial and establishes no cause. It followed 31,823 Swedish women aged 48 to 83, of whom 419 were hospitalised for or died of heart failure.

Sucrose-sweetened beverages linked to obesity
In a six-month trial, 47 overweight people drank a liter a day of regular cola, semi-skim milk, diet cola or water. Regular cola raised liver fat by 132 to 143 percent, muscle fat by 117 to 221 percent and visceral fat by 24 to 31 percent, with no difference in total fat mass.

Omega-3 fatty acids linked to lower cardiac arrest risk
In a case-control study of 334 primary cardiac arrest patients and 493 controls near Seattle, published in JAMA, eating 5.5 grams of long-chain omega-3 fatty acids a month was correlated with a 50 percent lower risk after adjustment for potential confounders.

Prenatal intake of non-organic dairy products linked to hypospadias in offspring
In a case-control study of 305 boys with hypospadias and 306 without, mothers who often ate high-fat dairy such as milk and butter but rarely chose organic versions were 118 percent more likely to have a boy with the defect. Organic choice overall showed no link to the birth defect.

Eating fish linked to lower risk of stroke
A meta-analysis of 16 cohort studies covering 402,127 people and 10,568 strokes found those eating fish five times a week had 13 percent lower stroke risk than those eating it less than monthly. The inverse association was stronger for ischemic than hemorrhagic stroke.

Drinking coffee linked to lower stroke risk
A meta-analysis of 10 cohort studies covering 442,098 people found moderate coffee drinkers 18% less likely to have a stroke and heavy drinkers 21% less likely than those drinking a cup a day or less. It was not a trial, so cause remains unproven.

Obesity Epidemic Not Due to High Fructose Corn Syrup?
A review in the International Journal of Obesity found no short-term health differences between high fructose corn syrup and table sugar and concluded HFCS is not behind the US obesity epidemic. Mercola notes the authors' corn industry ties and says the two sugars metabolize differently.

Cruciferous vegetables prevent many cancers - review study
Pooling Italian and Swiss case-control studies, researchers found people eating cruciferous vegetables at least weekly had 17% lower risk of oral or pharyngeal, colorectal and breast cancer, 28% lower esophageal risk and 32% lower kidney cancer risk than those eating none.

Processed meat linked to type 2 diabetes, coronary heart disease
A meta-analysis of prospective cohorts tied 50 grams a day of processed meat to 42% higher coronary heart disease risk and 51% higher type 2 diabetes risk. Unprocessed meat showed little or no increase, with 100 grams a day linked to 19% higher diabetes risk.

Red meat, processed meat linked to esophageal cancer
In the Netherlands Cohort Study of 120,852 people, men in the top fifth of red meat intake were 2.66 times as likely, and of processed meat 3.47 times as likely, to develop esophageal squamous cell carcinoma. No link appeared for other subtypes or in women.
