Go fish

There’s no scientifically proven diet for memory or brain optimisation, but for lifelong cognitive health, experts point to author Michael Pollan’s succinct advice: eat food, not too much, mostly plants. And when you do choose an animal protein, you might like to favour seafood. You’ve probably heard that fish feeds the brain and that’s because the omega-3 fatty acids in fish can build and repair that all-important myelin in the brain which is central to memory, problemsolving and focus. When we eat fish, the oil is “accompanied by a whole bunch of micronutrients and other foodstuffs that complement it and help it work,” says Dr Levitin.
