Diet
High protein diet may cause chronic kidney disease
A Danish review argues high-protein diets from meat and dairy, often promoted for weight loss, raise the risk of glomerular hyperfiltration, hypertension and kidney stones, and might increase chronic kidney disease risk even in people with healthy kidneys.
Supplements
Chlorella vulgaris supplements help NAFLD
In an eight-week trial at Tabriz University, 60 NAFLD patients took vitamin E with either chlorella vulgaris tablets or placebo. Both groups improved, but the chlorella group saw larger drops in weight, alkaline phosphatase and fasting blood sugar. Authors call it a possible add-on.
Food
Pulses good for your health
A review reports that pulses such as beans, peas and lentils supply protein, fiber, vitamins and minerals, and that eating them can improve serum lipid profiles and affect blood pressure, platelet activity and inflammation. Their fiber also helps steady blood glucose and insulin in diabetes.
Supplements
Black seed, garlic help fructose induced metabolic syndrome
In rats fed a high-fructose diet, supplements of black seed or garlic, alone or together, largely restored the weight, cholesterol, triglyceride and liver enzyme changes the diet caused, King Saud University researchers report in the Journal of Oleo Science.
Vitamins
Vitamin D: a critical and essential micronutrient for human health
A Frontiers in Physiology review by DSM Nutritional Products scientists notes vitamin D3 comes either from sunlight on skin or from a short list of foods, and links severe deficiency to bone disease, with autoimmune, cancer and cardiovascular connections still under discussion.
Food
Processed red meat linked to high blood pressure
Following 44,616 French women from 1993 to 2008, researchers recorded 10,256 new hypertension cases and found those eating five or more servings of processed red meat a week were 17% more likely to develop it. Unprocessed red meat showed no such association.
Vitamins
Vitamin D may prevent dementia, Alzheimer’s disease - study
Following 1,658 dementia-free people over 65 for about six years, researchers reporting in Neurology found those with low vitamin D were 53 percent more likely to develop dementia and the severely deficient 125 percent more likely, with similar figures for Alzheimer's disease.
Supplements
Caffeine intake associated with lower incidence of tinnitus
Following more than 65,000 women in the Nurses' Health Study II for 18 years, researchers counted 5,289 cases of tinnitus and reported 15% lower incidence among women consuming 450 to 599 mg of caffeine a day than among those taking in under 150 mg.
Food
Eating baked or broiled fish weekly boosts brain health, Pitt study says
Pitt researchers report that people who ate baked or broiled fish weekly had larger brain volumes in regions tied to memory and cognition. They found no relationship to omega-3 levels and conclude broader lifestyle factors, of which diet is one part, may be at work.

Warning to parents on high acidity drinks
University of Adelaide dental researchers report in the Journal of Dentistry that acid begins damaging tooth enamel within the first 30 seconds of exposure. They warn that acidic soft drinks, juices and sports drinks, combined with night-time grinding and reflux, threaten young people's teeth.
Vitamins
Vitamin D reduces the death risk in breast cancer patients
A meta-analysis of 30 prospective studies in the British Journal of Cancer tied the highest vitamin D intake to 5 percent lower breast cancer risk and higher serum 25(OH)D to an 8 percent reduction. Patients with high 25(OH)D were 42 percent less likely to die of breast cancer.
Biotics
Soluble fiber helps irritable bowel syndrome
A meta-analysis of 14 trials covering 906 patients found soluble fiber helped people with irritable bowel syndrome, while bran did not.
Supplements
L-carnitine supplements help coronary artery disease
In a trial of 47 coronary artery disease patients, half took 1,000 mg of L-carnitine daily for 12 weeks. The supplement lowered malondialdehyde and raised antioxidant enzyme activity, which the authors read as reduced oxidative stress. Published in Nutrition Journal.
Herbs
Ginkgo Biloba may help Alzheimer's patients receiving cholinesterase inhibitors
Among 828 Alzheimer's patients followed a year, those taking Ginkgo biloba alongside cholinesterase inhibitors differed significantly from inhibitor-only patients on Mini Mental State Examination scores, though not on ADAS-Cog or activities of daily living.

History and Experience: A Survey of Traditional Chinese Medicine Treatment for Alzheimer's Disease
A research article in Evidence-Based Complementary and Alternative Medicine surveying how traditional Chinese medicine, practiced in China for more than 2,000 years, has been used to treat Alzheimer's disease.
Herbs
Jiang Tang Xiao Ke Wan fights diabetes mellitus
In rats with induced diabetes fed a high-fat diet, four weeks of the Chinese herbal formula Jiang Tang Xiao Ke Wan lowered serum glucose 12 percent, triglycerides 57 percent and LDL 44 percent, an effect the researchers compare with pioglitazone. Published in Evid.-Based Compl. Alt. Medicine.
Herbs
Aralia root bark extract helps glipizide better treat type 2 diabetes mellitus
In a trial of 148 patients with type 2 diabetes, adding Aralia root bark extract to glipizide for eight weeks lowered HbA1c more than glipizide alone and also cut total and LDL cholesterol. The authors describe the added benefit as moderate.
