Which foods help your brain during exams?

Oily fish, spinach, blueberries, walnuts and eggs are all linked to brain benefits, though several rely on single studies.

Salmon and other oily fish contain omega-3 fats, which are important for brain health. Regular omega-3 fats can help keep mood stable and reduce symptoms of anxiety and stress.

One study linked half a cup of raw spinach a day to better thinking skills in late teenage boys. Blueberries contain plant compounds called polyphenols, which are linked to better brain health over a lifetime.

One small study found children recalled memories more quickly two to six hours after eating the equivalent of 1½ cups. One study from Spain found teens who ate a handful of walnuts each day for six months paid better attention.

The teens were likely also loosely following a Mediterranean diet, so the benefits could have several causes. Eggs contain choline, which is known to help with planning, problem solving and working memory.

Why it mattersRegular snacks such as nuts or an apple can help during long study sessions, because your brain needs energy.

AustraliaStudents sitting end-of-year exams can use these simple food ideas, such as eggs on wholegrain toast or a handful of nuts.
