Eating shellfish like prawns and scallops once a week can protect your brain against age-related memory loss and other cognitive problems, thanks to their high levels of omega 3 fatty acids and low levels of toxic compounds such as mercury. Research published in the journal Neurology found that subjects who ate seafood less than once a week suffered faster and greater mental decline that those who shelled out weekly. Both prawns and scallops contain around 200 milligrams of omega 3 per 85g serving, while containing little neurotoxins like mercury, which can accumulate in fish such as tuna that are higher up the food chain. Try this shellfish stir-fry to keep your brain sharp.
