Researchers have discovered a molecule that accumulates with age and inhibits the formation of new neurons. The finding might help scientists design therapies to prevent age-related cognitive decline.

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).

People sometimes take fish oil hoping that it will help alleviate inflammation-related conditions such as arthritis or allergies. A new epidemiological study supports this long-presumed benefit of seafood-source omega-3s ... whose credibility is bolstered by their proven biological effects. We should note that, with regard to specific conditions, the precise inflammation-related powers of fish oil remain to be proven by high-quality clinical trials.

Although there have been conflicting reports on the benefits of omega-3 fish oil, a new study indicates that it’s still a good idea to take the supplement.
Scientists at the Linus Pauling Institute of Oregon State University analyzed studies of omega-3 fish oil supplements and reached several conclusions. They said that taking the supplement, as well as eating fatty fish, may prevent heart disease, and that the supplement could be beneficial for serious health problems besides heart disease.

The Council for Responsible Nutrition (CRN), the dietary supplement industry's leading trade association, has released its comprehensive report, The Benefits of Nutritional Supplements (4th Edition).
The updated book assesses the current state of the science on the health benefits associated with select nutritional supplements. It looks at positive studies as well as null and negative study results.
Specifically, the report addresses multivitamins, antioxidants (vitamins C and E), calcium, long chain omega-3 fatty acids (fish oils), vitamin D, vitamins B-6 and B-12, fiber and folic acid.
The report can be downloaded (individual chapters or in its entirety) at the CRN website. Delete the scoop?

The American Heart Association and other leading health authorities recommend consuming fish oil and fatty fish high in omega-3 fatty acids, for two reasons:
1) To help prevent strokes and cardiovascular disease in healthy people.
2) To reduce the risk of stroke, sudden death, or a second heart attack among patients diagnosed with cardiovascular disease.
So consider salmon, mahi mahi, tilapia, or other sustainable fish for your summer grilling protein. They are delicious and will keep your heart healthy, your brain strong, and your eyesight sharp.

Sugar reduces plasticity in the brain and makes it harder to learn and remember. From children growing up with high levels of fructose, to college students with snacks and studies, to adults using sweetened convenient foods and trying to get ahead, everyone can be held back by sugar.

There is a large body of evidence to suggest that omega-3s are beneficial for brain health and heart health. A new study evaluated omega-3 supplements and their effect on cognitive performance. The findings supported established health benefits of these supplements.
The researchers concluded that supplementation with omega-3 polyunsaturated fatty acids (PUFA) could postpone the onset of metabolic disorders and associated declines in cognitive functioning. Delete the scoop?

Omega-3 fatty acid supplementation lowered the concentration of inflammatory cytokines in a research study. The data incdicates that maintaining a healthy (higher) ratio of omega-3: omega-6 fats can reduce the impact of aging on cellular health.
Inflammation, oxidative stress, and immune cell aging together lead to higher incidence of disease. Nutritional supplementation, including omega-3s can impact and reduce this damage. Delete the scoop?

Moderate exercise, and a regular intake of oily fish fatty acids, keeps elderly immobility at bay.
A small study of women found that omega-3 fatty acids plus exercise increased muscle strength by 20%, almost twice as much as when olive oil was used.
Exercise combats the natural muscle loss associated with aging. Maintaining adequate protein intake and staying active are already known to mitigate the rate of degeneration. It now appears that adding omega-3s could significantly boost this effect.
A larger study is planned, including men and women. Delete the scoop?

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.

A critical genetic variation rules our ability to make essential omega-3s from plant foods; this may explain why rates of disease vary by ethnicity and diet.
