Omega-3 linked to lower body weight: Study

Omega-3 linked to lower body weight: Study

Increased blood levels of the omega-3 fatty acids EPA and DHA is linked to lower incidence of obesity, suggesting a role for fish oils in weight management.

New findings reported in the British Journal of Nutrition indicate that overweight and obese people have blood levels of omega-3 fatty acids almost 1 per cent lower than people with a healthy weight.

“Our findings suggest that n-3 PUFA may play an important role in weight status and abdominal adiposity,” wrote the researchers, led by Professor Monohar Garg from the University of Newcastle, and president elect of the Nutrition Society of Australia.

Previous studies have implicated omega-3 in protective benefits against obesity, and the new study adds to this small but growing body of evidence. A considerable number of studies already support the benefits of the omega-3 fatty acids eicosapentaenoic acid (EPA, C20:5 n-3) and docosahexaenoic acid (DHA, C22:6 n-3) for cardiovascular health, and cognitive health. Other areas of potential for the fatty acids include mood and behaviour, eye health, cancer risk reduction, and improved infant development.

“Previous studies involving children and adolescents have shown a negative correlation between adiposity and plasma omega-3 PUFA and DHA concentrations, but there appears to be a paucity of research in adults,” explained the researchers.

Insulin Resistance- cause of ADD, diabetes, narcolepsy, etc etc

Insulin Resistance Insulin Resistance Have you been diagnosed with clinical depression? Heart disease? Type II, or adult, diabetes? Narcolepsy? Are you, or do you think you might be, an alcoholic? Do you gain weight around your middle in spite of faithfully dieting? Are you unable to lose weight? Does your child have ADHD? If you have any one of these symptoms, I wrote this article for you. Believe it or not, the same thing can cause all of the above symptoms. I am not a medical professional. I am not a nutritionist. The conclusions I have drawn from my own experience and observations are not rocket science. A diagnosis of clinical depression is as ordinary as the common cold today. Prescriptions for Prozac, Zoloft, Wellbutrin, etc., are written every day. Genuine clinical depression is a very serious condition caused by serotonin levels in the brain. I am not certain, however, that every diagnosis of depression is the real thing. My guess is that about 10 percent of the people taking ...

Could Narcolepsy be caused by gluten? :: Kitchen Table Hypothesis

Kitchen Table Hypothesis from www.zombieinstitute.net - Heidi's new site It's commonly known that a severe allergy to peanuts can cause death within minutes. What if there were an allergy that were delayed for hours and caused people to fall asleep instead? That is what I believe is happening in people with Narcolepsy. Celiac disease is an allergy to gliadin, a specific gluten protein found in grains such as wheat, barley and rye. In celiac disease the IgA antigliadin antibody is produced after ingestion of gluten. It attacks the gluten, but also mistakenly binds to and creates an immune reaction in the cells of the small intestine causing severe damage. There is another form of gluten intolerance, Dermatitis Herpetiformis, in which the IgA antigliadin bind to proteins in the skin, causing blisters, itching and pain. This can occur without any signs of intestinal damage. Non-celiac gluten sensitivity is a similar autoimmune reaction to gliadin, however it usually involves the...

Blue-blocking Glasses To Improve Sleep And ADHD Symptoms Developed

Blue-blocking Glasses To Improve Sleep And ADHD Symptoms Developed Scientists at John Carroll University, working in its Lighting Innovations Institute, have developed an affordable accessory that appears to reduce the symptoms of ADHD. Their discovery also has also been shown to improve sleep patterns among people who have difficulty falling asleep. The John Carroll researchers have created glasses designed to block blue light, therefore altering a person's circadian rhythm, which leads to improvement in ADHD symptoms and sleep disorders. […] How the Glasses Work The individual puts on the glasses a couple of hours ahead of bedtime, advancing the circadian rhythm. The special glasses block the blue rays that cause a delay in the start of the flow of melatonin, the sleep hormone. Normally, melatonin flow doesn't begin until after the individual goes into darkness. Studies indicate that promoting the earlier release of melatonin results in a marked decline of ADHD symptoms.
