A diet rich in walnuts and walnut oil may prepare the body to deal better with stress, according to a team of Penn State researchers who looked at how these foods, which contain polyunsaturated fats, influence blood pressure at rest and under stress. Previous studies have shown that omega-3 fatty acids -- like the alpha linolenic acid found in walnuts and flax seeds -- can reduce low density lipoproteins (LDL) -- bad cholesterol. These foods may also reduce c-reactive protein and other...

For the past 25 years or more health experts have warned that saturated fat was a major cause of heart attacks and cardiovascular disease (CVD). However, new evidence has shown that saturated fat intake has only a very small impact on the risk of CVD, which has caused many experts to change their stance on the evils of saturated fat. The Global Dairy Platform has promoted several research articles published in the October issue of Lipids, which provides evidence of recent advances in...

Researchers in France reported Friday that overeating combined with the wrong mix of fats in one's diet can cause obesity to be carried over from one generation to the next. The scientists showed in experiments that too much omega-6 and not enough omega-3 can lead to overweight offspring. The ratio of omega-6 to omega-3 in a typical Western diet has shifted from 5-to-1 to 15-to-1 in much of Europe, and up to 40-to-1 in the U.S. The average ratio in the breast milk of American women has...

UAB researchers decode a cascade of signals within tumour cells activated by olive oil The researchers decoded a complete cascade of signals within breast tumour cells activated by virgin olive oil, and concluded that benefits include decrease in the activity of the oncogene p21Ras, changes in protein signaling pathways, stimulation of tumour cell death and prevention of DNA damage. The study was carried out in an experimental model and researchers have already begun a new study with human...

The largest ever trial of fish oil supplements has found no evidence that they offer benefits for cognitive function in older people. The OPAL study investigated the effects of taking omega-3 long-chain polyunsaturated fatty acid supplements over a two year period on the cognitive function of participants aged 70-80 years. The number of people with cognitive impairment is rising and it is estimated that by 2040, more than 81 million people globally will have dementia. Some studies have...

According to a University of Illinois study, omega-3 fatty acids may be good for more than heart health. A little-known omega-3 may have implications for treating male infertility. "In our experiment, we used 'knockout' mice that lacked the gene responsible for an enzyme important in making docosahexaenoic acid (DHA). In the absence of DHA, male mice are basically infertile, producing few if any misshaped sperm that can't get where they need to go," said Manabu Nakamura, a U of I associate...

New study just the second dietary intervention to show a reduction in coronary heart disease Although for nearly 60 years people have been urged to decrease their consumption of saturated fats to prevent heart disease, until now there has been surprisingly little scientific evidence that doing so actually decreased the risk of coronary heart disease events. A new study by researchers at Harvard School of Public Health (HSPH) provides the first conclusive evidence from randomized clinical...

UC Davis research shows walnuts affect genes related to tumor growth Walnut consumption slows the growth of prostate cancer in mice and has beneficial effects on multiple genes related to the control of tumor growth and metabolism, UC Davis and the U.S. Department of Agriculture Western Regional Research Center in Albany, Calif. have found. The study, by Paul Davis, nutritionist in the Department of Nutrition and a researcher with the UC Davis Cancer Center, announced the findings today at...

Post-menopausal women who reported consuming the most daily dietary fat had a 40 percent higher incidence of clot-caused strokes compared to women who ate the least amount, according to research presented at the American Stroke Association's International Stroke Conference 2010. The incidence of ischemic stroke also increased by 30 percent in the quartile of women consuming the highest daily amount of trans fat (average intake 7 grams per day) compared to those who consumed the least (average...

Individuals at extremely high risk of developing psychosis appear less likely to develop psychotic disorders following a 12-week course of fish oil capsules containing long-chain omega-3 polyunsaturated fatty acids, according to a report in the February issue of Archives of General Psychiatry, one of the JAMA/Archives journals. "Early treatment in schizophrenia and other psychoses has been linked to better outcomes," the authors write as background information in the article. "Given that...
