Brain food

Don’t stop at fuelling your body for peak performance – you need to feed your brain, too.

The concentration sharpner - Docosahexaenoic acid


About 50 per cent of the human brain is made of fat, of which a large portion is docosahexaenoic acid (DHA), but this supercharged omega-3 cannot be made by the body and comes solely from dietary sources. This matters because studies show that DHA plays a big role in boosting mental focus and concentration levels during exercise. ‘DHA makes brain cells more receptive to messages from neurotransmitters,’ explains Ruxton. 


Eating eggs to power up on protein is a no-brainer, but they’re now a great source of DHA, too. According to Ruxton, changes in hen feed have helped convert egg fats into DHA. Go for a post-run sarnie filled with egg and omega-rich avocado for a powerful protein/fatty-acid combo. Or get your fix from fish oil. Research published in the Journal of Applied Physiology found six grams a day delivers enough to DHA to improve performance.
