The authors argue that chronic systemic inflammation links rheumatoid arthritis to cardiovascular disease, and that the marine omega-3 fats EPA and DHA may address both. At least 6 of 14 well-controlled trials found the supplements reduced joint inflammation.

Cancer news: Whole walnuts may help prevent prostate cancer
Mice on a high-fat diet containing whole walnuts had slower prostate tumour growth and lower tumour weight than controls on soybean-oil diets, plus lower prostate weight, IGF-1, resistin and LDL at 18 weeks, across a 24-week feeding study.

Diets high in Omega 3 fatty acid, vitamin B, C, D and E help prevent Alzheimer's disease
A study in Neurology found people with higher blood levels of omega-3 fatty acids and vitamins B, C, D and E were less likely to show the brain shrinkage tied to Alzheimer's and scored better on thinking and memory tests, while high trans fat diets tracked with the opposite.

Meat, vegetable oils may boost risk of inflammatory bowel disease
Vibeke Andersen's review ties diets high in protein, particularly animal protein, to more inflammatory bowel disease and relapses, and finds omega-6 fats from corn and soybean oil may predispose to ulcerative colitis while fish-derived DHA and EPA may protect.

The Antioxidant that Makes Fish Oil Work Better
A new study found that adding astaxanthin to fish oil makes the oil less prone to oxidation and strengthens its immunomodulatory properties. Mercola argues many fish oils on sale are already rancid and recommends krill oil, which contains astaxanthin naturally.

Suffer a stroke? Use omega-3 to reduce the stroke-induced damage
Mice given DHA supplements for three months after a stroke had 25 percent less stroke-induced brain damage, according to a study in Stroke. The Universite Laval authors point to the omega-3 fatty acid's anti-inflammatory effect as the likely explanation.

The Incredible Oil that Helps Prevent Heart Attacks (And Stalls Aging Too!)...
Omega-3 researcher William Harris recounts finding that fish oil lowered triglycerides rather than cholesterol in his early work, and how Greenland studies by Dyerberg and Bang pointed to a high omega-3 diet as protection against heart attacks.

Vitamin C, Omega 3 fatty acids cut death risk from cardiovascular disease
Following 58,730 Japanese adults for 16.5 years, researchers found women with the highest vitamin C intake were 30% less likely to die of stroke and 37% less likely to die of coronary heart disease. The association was not significant in men, and vitamins A and E showed none.

Omega-3 Fatty Acids Linked to Prostate Cancer Risk
Among 3,461 men in the Prostate Cancer Prevention Trial, those with the most DHA in their blood were two and a half times more likely to have aggressive prostate cancer, Fred Hutchinson researchers report, echoing the EPIC study. The piece lists other trials where fish oil showed no benefit.

Fish oil may help fight breast cancer
Rats with chemically induced mammary tumors fed fish oil with tamoxifen showed lower expression of genes that drive tumor growth and spread than rats on corn oil. Fish oil also raised some immunity genes tied to inflammation, which may work against the benefit.

Prenatal omega-3 curbs risk for postpartum depression symptoms (PR)
Michelle Price Judge of the University of Connecticut, who earlier showed maternal DHA gives infants a developmental edge nine months after birth, asks here whether greater omega-3 intake during pregnancy lowers the risk of postpartum depression symptoms.

Omega-3 fatty acids ward off macular degeneration
Among more than 38,000 women in the Women's Health Study followed for 10 years, with 235 cases, regular DHA, EPA and fish intake, at least one serving of fish weekly, was associated with a 35 to 45% lower risk of visually significant macular degeneration.

FDA: Don't Use Dietary Supplement Rock Hard Extreme
The FDA warned consumers away from the supplements Rock Hard Extreme and Passion Coffee after lab tests found synthetic sulfaildenafil, a chemical close to Viagra's sildenafil, which can interact with nitrates and drop blood pressure to dangerous levels.

Study explains why omega-3 fatty acids prevent breast cancer
Omega-3 ethyl esters suppressed NF-kB transcriptional activity in luminal A, luminal B and basal breast cancer cell lines but had no effect on HER2-overexpressing cells, suggesting omega-3s may act against only some subtypes. Ongoing clinical trials should settle the question.

Eating fish may not help Alzheimer's disease or dementia - study
Following 5,395 older adults in Rotterdam for 10 years, with 465 dementia cases, researchers found no association between eating fish or fatty fish, or omega-3 intake, and the risk of dementia or Alzheimer's disease.

Omega-3 fatty acids help prevent breast cancer - study
Among 72,571 cancer-free women in the Shanghai Women's Health Study followed about eight years, those eating little marine omega-3 fat alongside a lot of omega-6 fat were twice as likely to develop breast cancer as women with high marine omega-3 intake.

Pink News: Fish oil prevents breast cancer
Following 35,000 women aged 50 to 76, Fred Hutchinson researchers found current fish oil use accompanying 32 percent lower breast cancer risk. The drop showed only for ductal tumours; black cohosh, dong quai, soy and St. John's wort showed no link.
