Your brain runs off of carboyhoydrates. Eating Whole grains are important during exam season to keep enough glucose running your brain. A bowl of oats could sharpen your focus and keep you concentrating. Adding a banana will help reduce pre-exam jitters, bananas are the only natural Beeta blockers!
• Oily fish (salmon, mackerel or sardines) or if (alternatively your vegan) flaxseeds, walnuts, pumpkin seeds. Omega three fats are essential for healthy brain function + can only be obtained by our diet! Omge three also raises serotonin levels helping us to feel less stressed.
• Fruit + Veg - Vitamin C is long known for making us feel less stressed and ahieve better brain ability, eat your fruit + veg! Broccoli is high in Vititmin C and Vititmin K = apparently helps us keep memory + brain sharp.
Hope this helped!
