This week, we love Kellogg’s new Live Bright Brain Health Bars. For those who want to consume the right amount of essential fatty acids like DHA-3 (Docosahexaenoic acid) but don’t like the taste of fish, a natural source of these healthy fats, then look no further than Kellogg’s Live Bright Brain Bars.

DHA plus eicosapentaenoic acid (EPA), another essential fatty acid, are believed to have beneficial effects in reducing cardiovascular disease and other chronic conditions. DHA, in particular, is found in the brain where it is  needed for mental clarity and development and visual acuity and is different from a-linolenic acid (ALA) which is found in flax seed, walnuts and canola oil. Low levels of DHA have been found in children with ADHD and DHA was found to reduce inflammatory markers in men who are at risk for heart disease.

Cutting calories may do more than just trim your waistline. A new study suggests that cutting calories may boost your memory as well.

“Even though the number of subjects in the study was not really high, they had really high, statistically significant improvements in their performance on the memory test,” says Mark P. Mattson, a senior investigator at the National Institute on Aging (NIA) in Bethesda, Maryland.

Ginkgo biloba has been touted for its cognitive boosting properties, but the purported memory aid is being doubted these days. According to a study in the Journal of the American Medical Association conducted by the University of Pittsburgh, it didn’t help prevent Alzheimer’s or other forms of dementia in more than 3,000 elderly study subjects.

Ginkgo manufacturers, predictably, say this isn’t true.

“There is a significant body of scientific and clinical evidence supporting the safety and efficacy of ginkgo extract for both cognitive function and improved circulation,” says Mark Blumenthal, executive director of the American Botanical Council.

No matter who is on the right side of the argument, there is one proven way to improve your memory and overall brain function: exercise. Researchers at Duke University demonstrated that exercise can be an effective antidepressant. Exercise produces serotonin, dopamine and norepinephrine, which have been associated with elevated mood.
