Do Omega-3 Fatty Acids Really Bolster Aging Brains?

“Eat your fish – it’s brain food,” our mothers told us, and we repeat that mantra to our own children. For years we’ve heard that fish, especially fatty fish such as salmon, is good for our brain health. And many scientists identified omega-3 fatty acids as the substance in the fish that would help our math skills, keep us alert and preserve our brain health. That made sense because omega-3 fatty acids – which are also found in high levels in …

The fatty-fish eaters may also be able to reduce their chances of dying from heart disease by more than a third. The study of 2,700 adults age 65 or older found that those who had the highest blood levels of …

Think That’s Real Tuna You’re Buying? Think Again

That rosy slab of fresh tuna you bought for dinner? There’s a good chance it’s not really tuna. And the tuna sushi you ordered the other night? It’s almost certainly not tuna. The nonprofit ocean-protection group Oceana conducted one of the largest seafood-fraud investigations in the world from 2010 to 2012.
