Omega-3 fatty acid supplementation could help with cognitive depression

Duke University, August 27 2022. 

 

An article appearing in the Journal of the American College of Cardiology: Heart Failure reported the outcome of a pilot study that found an association between supplementation with the omega-3 fatty acids EPA and DHA and reduced cognitive depression in heart failure patients. Cognitive depression is characterized by subjective symptoms such as pessimism and sadness, while somatic depression includes physical manifestations that include fatigue and sleep disturbances.

The study included 108 patients with a major depressive disorder, chronic heart failure and low blood levels of omega-3 fatty acids. Participants received fish oil containing EPA and DHA, a high EPA supplement or a placebo daily for 12 weeks. Blood samples collected before and after treatment were evaluated for red blood cell EPA and DHA, the Omega-3 Index and other factors.

Omega-3 values increased in both the EPA/DHA and EPA only groups, while the placebo group showed little change. Higher omega-3 Index values were associated with lower cognitive depression scores. Social functioning as evaluated by a general health survey significantly improved with EPA/DHA supplementation and showed a tendency toward improvement in the high EPA group.

"This was a study in already depressed individuals, which meant the researchers are looking to high-dose (although it could have been higher) omega-3 supplements to improve depressive symptoms, like a drug," noted coauthor William S. Harris, PhD. "Generally, we think of the function of omega-3s as preventative rather than as treatment. If used as treatment, the dose must be fairly high (4 grams is a typical 'drug' dose) and blood levels must be measured.”

 

Groundbreaking Study Shows Fasting Can Slow Aging, Rebuild Immune System

University of Southern California, August 28, 2022

Cutting-edge research reveals that occasionally adopting a diet that mimics the effects of fasting may provide dramatic health benefits.

“Fasting flips a regenerative switch essentially regenerating the entire immune system. It gives the OK for stem cells to go begin proliferating and rebuild the entire system,” said Prof Valter Longo, Professor of Gerontology and the Biological Sciences at the University of California.

A study, led by USC’s Dr. Valter, revealed that a “cycles of a four-day low-calorie diet that mimics fasting (FMD) cut visceral belly fat and elevated the number of progenitor and stem cells in several organs of old mice — including the brain, where it boosted neural regeneration and improved learning and memory,” according to USC News.

Dr. Longo notes that strict fasting can be difficult for people to adhere to, and also has the potential to be dangerous, while pointing out that a fasting mimicking diet is much safer and easier.

“Strict fasting is hard for people to stick to, and it can also be dangerous, so we developed a complex diet that triggers the same effects in the body,” said Longo, Edna M. Jones Professor of Biogerontology at the USC Davis School of Gerontology and director of the USC Longevity Institute. “I’ve personally tried both, and the fasting mimicking diet is a lot easier and also a lot safer.”

The fasting mimicking diet cuts a person’s daily caloric intake over the fasting period down to 34 to 54 percent of their daily average, with a specific balance of micronutrients, fats, carbohydrates, and proteins.

In previous groundbreaking research, Longo has shown how fasting can protect immune and other cells from chemotherapy toxicity, while simultaneously starving out cancer cells. Fasting for seventy-two hours protected cancer patients against the toxic impact of chemotherapy:

“The good news is the body got rid of the parts in the system which might be damaged or old and inefficient parts, during the fasting. If you start with a system heavily damaged by chemotherapy or aging, fasting cycles can genera
