• Peaks and troughs in blood sugar interrupt the brain’s sugar supply which needs to be kept as steady as possible.  Switch refined carbohydrates for whole, natural, unprocessed foods, eat at regular intervals and include protein with every meal or snack.

  • Stock up on Vitamin B12.  It has an essential role in neurotransmitter production which are needed for learning, memory and mood.  It is found in eggs, meat, milk, cheese and fish. N.B. A supplement may be necessary for a) Vegans as B12 is only available from animal products and fortified processed foods and b) Some people have trouble absorbing B12 from foods. 

  • Eat oily fish 3 times a week (sardine, mackerel, wild salmon, herring) or take a clean fish oil (or algae, for vegans) supplement.  An insufficiency of omega 3 fatty acids has been linked to low mood.
