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.

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.

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.

As I side note don't buy the cheap stuff sold at drugstores, grocery stores and big box buying clubs. When you go for price you sacrifice quality!

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.

Another reason to eat organic: a dangerous pesticide has been confirmed to kill honeybees. This toxin is entering our environment through factory farming methods.
A recent study showed that this EPA-approved GMO insecticide is responsible for killing off honeybees, which is a serious threat to the food supply. This chemical is also helping contaminate the entire food chain...

Pese a las ventajas que proporcionan los organismos transgénicos para poder ser resistentes a plagas o a factores ambientales, esa manipulación genética no siempre resulta del todo beneficiosa y puede llegar a tener consecuencias dramáticas. Por ello, la regulación de los organimos transgénicos y su control antes de salir al mercado, es fundamental.
