Queen Mary researchers gave healthy volunteers 250 ml of beetroot juice or nitrate capsules and found both lowered blood pressure within 24 hours, with larger drops in those starting higher. Whether people with hypertension would see the same effect is still unknown.

Fructose sugar makes maturing human fat cells fatter, less insulin-sensitive (PR)
In fat biopsies from 32 healthy-weight prepubertal children, fructose present while precursor cells matured pushed more of them into fat cells in belly fat and left cells in both belly and under-skin fat less responsive to insulin, a University of Bristol researcher told The Endocrine Society.

Polyphenols Halt Prostate Cancer Growth
In vitro work found that green tea and wine polyphenols had to block the SphK1/S1P signaling pathway to kill prostate cancer cells, and mice given EGCG or polyphenon E showed a sharp drop in implanted tumor size.

Vitamin D fights HIV
Among 884 HIV-infected pregnant women in Tanzania followed about 69 months, those with serum vitamin D under 32 ng/mL were 25 percent more likely to progress to WHO stage III or worse and 47 percent more likely to develop severe anemia, a PLoS One study found.

Americans eat too much salt: What you need to know
A CDC survey of 2005-2006 data found only 9.6 percent of US adults kept sodium within their recommended limit, with 5.5 percent under 1,500 mg a day and 18.8 percent of the rest under 2,300 mg. Studies have linked high intake to gastric cancer, osteoporosis and kidney stones.

Vitamin D boosts cognitive function
Tufts researchers analysed data on more than 1,000 home-care patients aged 65 to 99 and found those with sufficient vitamin D scored better on cognitive tests, particularly measures of executive performance such as reasoning and cognitive flexibility. Many participants were deficient.
Minerals
Sodium Intake Among U.S. Adults
CDC's analysis of 2005-2006 NHANES data found only 9.6 percent of US adults kept sodium within their recommended limit: 5.5 percent of those advised to stay under 1,500 mg a day, and 18.8 percent of other adults under 2,300 mg.

Ginger Reduces Pain After Exercise
In a double-blind trial, participants took two grams of raw or heat-treated ginger or a placebo for 11 days, then did heavy arm exercise to induce muscle injury. Raw ginger cut exercise-induced pain by 25 percent within 24 hours and the heat-treated form by 23 percent.

Good News for Starbucks?
Pooling nine studies that compared 5,139 people with head and neck cancer to 9,028 without, University of Milan researchers found drinking four or more cups of caffeinated coffee a day was linked to 39 percent lower risk. No protection appeared for laryngeal cancer, and none for tea drinkers.

McDonald's Threatened with Lawsuit
The Center for Science in the Public Interest warned McDonald's it may sue unless the chain drops toys from Happy Meals, arguing they undermine parents and push children toward salty, fatty food. McDonald's cited smaller portions and an apple-slice option. CDC tips for parents follow.
Diet
Low carb diet better for obese women with insulin resistance
In a 12-week study of 45 obese women with insulin resistance, those assigned a low-carb diet lost 19.6 pounds against 16.2 pounds on a low-fat diet, a difference of 3.4 pounds. Jenny Craig funded the work, presented at an Endocrine Society meeting.
Supplements
Avoid These Toxic Protein Powders Until You Hear These Disturbing Details
Consumer Reports tested 15 protein powders and drinks and found three daily servings of several could push arsenic, cadmium or lead past proposed USP limits. Muscle Milk Chocolate powder contained all four metals tested, three at the highest levels found in the group.

Study: Kids Prefer Cartoon Packaging
Yale researchers watched 40 preschoolers taste graham crackers, gummy fruit snacks and baby carrots from plain packaging and from packaging bearing Dora, Shrek or Scooby Doo. The children preferred the character versions, which author Christina Roberto says makes packaging a maker's responsibility.

New evidence: vitamin D prevents flu
A PLoS ONE study followed 198 healthy adults through autumn and winter: 16.6% of those who kept serum vitamin D at 38 ng/ml or higher caught a viral respiratory infection, against 45% of those with lower levels.

Male menopause may be real
University of Manchester researchers studied 3,369 men aged 40 to 79 at eight European centres and concluded late-onset hypogonadism is real but rare, affecting about 2 percent of middle-aged men. Low testosterone tracked with poor morning erection and low sexual desire.

Salted fish ups intra-cerebral hemorrhage risk
In a Finnish survey of 3,958 adults, people whose salted fish intake fell in the highest third were 98% more likely to suffer intracerebral haemorrhage than those in the lowest. Total fish intake showed no link to cerebrovascular disease.
