A new study suggests adults with the highest levels of omega-3 fatty acids in their blood are less likely to die from a range of causes than those with the lowest levels.

 

Researchers found people with the most circulating omega-3s - usually found in oily fishes such as tuna or sardines - lived about two years longer than those with the lowest levels, on average.

 

 

Lab experiments and preliminary clinical studies indicate that curcuminoids support immune and brain health in uniquely powerful ways. And earlier this month, the authors of a review paper painted this positive picture of the substantial clinical evidence on curcumin:“Extensive clinical trials over the past quarter century have addressed the … efficacy of [curcumin and] promising effects have been observed in patients with various pro-inflammatory diseases including cancer, cardiovascular disease, arthritis … [and more than 25 others]. (Gupta SC et al. 2013).

 

 

Taking a multivitamin supplement daily can improve cognitive performance in both children and adults, say UK researchers.

 

A series of neurological studies evaluated multi-vitamin usage amongst men, women and children. The findings associated supplementation with improved cognitive effects and mood.

For pregnant women, supplements of an omega-3 fatty acid called Docosahexaenoic acid (DHA) may help to reduce the likelihood of giving birth very prematurely, according to a new study.

The results add to evidence that omega-3 fatty acid supplements make pregnancy last a little longer, which means more development time for babies before birth, less hospital time after birth and a better long-term health outlook.

 

 

How does fish oil protect the heart? The answer to this question has been elusive so far. Scientists know that omega-3 fatty acids exert an anti-inflammatory effect, but the mechanism had not been clearly followed.

 

A new study has now mapped the cellular process occurring after EPA supplementation and found that the nutrient blocks the cyclooxygenase enzyme (COX), which is a precursor to inflammation. COX produces hormones called prostaglandins, which cause inflammation in the body.

 

This is similar to the mechanism of aspirin, which blocks COX-2 signaling, thereby reducing inflammation and pain.
