Rats with Alzheimer's disease fed a vitamin D-free diet did worse in the Morris water maze than those on a supplemented diet, Iranian researchers report. Supplementation itself did not significantly change maze performance, leading the authors to urge protecting patients from deficiency.

Fish oil DHA doesn't help Alzheimer's disease - What you need to know
In an 18-month JAMA trial, 2 grams of DHA daily did not slow decline in people with mild to moderate Alzheimer's: cognitive scores shifted 8.27 points against 7.98 for placebo, and an MRI substudy showed no effect on brain volume.

Retina Implant Cures Blindness
A sub-retinal implant developed by Eberhart Zrenner's team let three blind patients make out shapes and objects within days, according to results in Proceedings of the Royal Society B. The 3mm chip carries 1,500 light sensors and targets retinitis pigmentosa.

Alcohol boosts pancreatic cancer risk - study
A meta-analysis of 21 case-control and 11 cohort studies in the International Journal of Cancer found people drinking three or more drinks a day were 22 percent more likely to develop pancreatic cancer. Separately, British scientists rated alcohol the most harmful drug overall.

Green tea helps prevent breast cancer or not?
A Japanese study of 53,793 women found no overall link between green tea and breast cancer over about 14 years. Those drinking 5 or more cups a day were 12 percent more likely to be diagnosed than those drinking under one a week, but the difference was not statistically significant.

Eczema, asthma and vitamin D
A reader's email to the Vitamin D Council asking Dr. Cannell whether his breastfeeding wife's and infant daughter's vitamin D doses are adequate and whether their eczema and asthma could be linked to vitamin D, preceded by an editor's appeal for donations to the organization.

Too much folate may boost breast cancer risk - study
Among 70,656 postmenopausal women followed from 1992, 3,898 developed breast cancer, and those in the highest quintile of dietary folate intake had a 12% higher risk. The authors saw no dose-response trend, and found no link for vitamin B-6, B-12 or total folate.

Could vitamin D deficiency explain sepsis risk in elderly people?
A JAMA study of 516 survivors of severe sepsis, average age 77, found 60 percent worsened in cognitive or physical function, and survivors were 3.33 times more likely to develop moderate or severe cognitive impairment. One health observer suggested vitamin D deficiency may play a part.

Update: Drinking green tea helps prevent breast cancer
An added warning says bottled green tea often contains little EGCG, so readers who want the effect must brew their own leaves. The underlying Harvard review of nine studies found more than three cups a day correlated with 27 percent lower breast cancer recurrence risk.

Wheat Bran Helps Type 2 Diabetes Mellitus Patients
A small Indian trial gave 15 of 30 type 2 diabetes patients aged 45 to 50 twenty grams of wheat bran daily for six months, measuring fasting and postprandial glucose and HbA1c against 15 who received none. It also cites a CDC projection that a third of Americans could have diabetes by 2050.

Tea, coffee don't cut breast cancer risk in black women - study
Boston University researchers tracking 52,062 women in the Black Women's Health Study recorded 1,268 breast cancers over 12 years and found no significant link to tea, coffee or caffeine. Four or more cups of tea a day tracked with 13 percent lower risk, but not significantly.

Bran Cuts Death Risk in Type 2 Diabetes Mellitus Patients
CDC researchers project that nearly a third of Americans could have type 2 diabetes by 2050 without action, against 7.8 percent in 2007. A Harvard study in Circulation found women with the disease who ate more bran died less often from all causes and from cardiovascular disease.

Psyllium fiber supplements help patients with diabetes mellitus
Bajorek and Morello reviewed seven studies and found psyllium fiber supplements and a low-glycemic-index diet improved glycemic markers, with 10.2 grams of psyllium a day lowering post-meal glucose and A1C. They call it a possible additional option for type 2 diabetes.
Vitamins
Antioxidants may help prevent breast cancer
An Indian study in the Asian Pacific Journal of Cancer Prevention measured plasma antioxidants in 225 women and found higher beta-carotene, vitamin E and vitamin C accompanying significantly lower breast cancer risk. Higher vitamin A levels went the other way, tracking with higher risk.

Nearly a third of Americans may live with diabetes by 2050 - study
CDC researchers project annual diagnosed type 2 diabetes cases will rise from 8 per 1,000 in 2008 to about 15 by 2050, with total prevalence going from 14% to 21% - or to 33% if incidence keeps climbing while mortality stays low. They blame aging, minority population growth and longer survival.

Choline, betaine may cut breast cancer death risk
Tracking 1,508 breast cancer patients on Long Island, researchers report in FASEB Journal that higher choline and betaine intake accompanied lower all-cause and breast cancer death in dose-dependent fashion. They call the nutrients a promising prevention strategy.

Could vitamin D work better than influenza vaccine?
The CDC urges everyone six months and older to take the 2010-2011 flu shot. The piece counters that neither cdc.gov nor flu.gov mentions vitamin D3, and cites researchers William Grant and John Cannell, who argue high doses boost innate immunity against influenza.

This Cooking Oil is a Powerful Virus-Destroyer and Antibiotic…
Mercola argues that not all saturated fats are alike, citing Pacific Island populations who get 30 to 60 percent of their calories from coconut oil and show nearly no cardiovascular disease, and contrasting naturally saturated fats with hydrogenated oils, or trans fats.
