It can be a stressful time.

Impending exams, a revision schedule to stick to, lack of sleep, and not enough time to eat.

But one University of Sunderland expert is warning students not to forget to feed their bodies, as well as their minds this exam season.

But can you give yourself an advantage simply by eating certain foods? And does drinking plenty of water really increase your chances of getting good grades?

Dr Paul Innerd is a Lecturer in Exercise Physiology at the University of Sunderland. Here he gives his views on the best nutrition to help see young people and students through this tough period.

Start with water. Make sure you get enough. You are roughly 70% water, so it’s important that you drink it. In fact, the brain is a mass of water, fat and some protein. Water allows brain functions to take place, such as thinking and memory.

Fatty fish

Fats are essential for good health and brain power. Fatty fish such as salmon is an excellent source of omega-3 fatty acids, particularly one called DHA (docosahexaenoic acid). DHA forms a major building block of brain development in children.
