How Omega – 3's Help The Nervous-System Function

WASHINGTON — The omega-3 essential fatty acids commonly found in fatty fish and algae help animals avoid sensory overload, according to research published by the American Psychological Association. The finding connects low omega-3s to the information-processing problems found in people with schizophrenia; bipolar, obsessive-compulsive, and attention-deficit hyperactivity disorders; Huntington’s disease; and other afflictions of the nervous system.

The study, reported in the journal Behavioral Neuroscience, provides more evidence that fish is brain food. The key finding was that two omega-3 fatty acids – docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) – appear to be most useful in the nervous system, maybe by maintaining nerve-cell membranes.

“It is an uphill battle now to reverse the message that ‘fats are bad,’ and to increase omega-3 fats in our diet,” said Norman Salem Jr., PhD, who led this study at the Laboratory of Membrane Biochemistry and Biophysics at the National Institute on Alcohol Abuse and Alcoholism.

Fat in your diet does not affect weight gain over time

Fat In your diet does not affect weight gain over time says Dr. Nita Forouhi—

NEW YORK (Reuters Health) – People who want to maintain a healthy weight over time shouldn’t obsess about their fat intake, new research shows.

The percentage of calories that a person got from fat, as opposed to protein or carbohydrates, had nothing to do with how much weight they gained in the coming years, the research team found.

The kinds of fat they ate didn’t matter either, Dr. Nita Forouhi of the Institute of Metabolic Science, Addenbrooke’s Hospital, Cambridge, UK and her colleagues found.

The findings, Forouhi noted in an email to Reuters Health, show that “it is more important to aim for a healthy lifestyle including a balanced healthy diet and regular physical activity, than to focus on fat intake alone as a factor for weight gain.”

The role of dietary fat content in obesity and weight gain is still controversial, Forouhi and her team note. To investigate, they looked at data on nearly 90,000 men and women from six different countries participating in the European Prospective Investigation into Cancer and Nutrition Study. Participants were followed for up to 10 years. Source
