Nutritional therapist, Jane Jo Lewis recommends eating well to optimise both mental and physical health.
Low GI wholegrain foods such as oats, brown cereals and pasta along with wholegrain bread, can help slowly release glucose into your body; a great source of energy- ideal for long stretches of revision or exam prep.
Good sources of fatty acids including; linseed (flaxseed) oil, soya bean oil, pumpkin seeds, walnut oil and soya beans are suggested for a good functioning brain. Whilst binging on blueberries and tomatoes may be effective in improving or delaying short term memory loss- making it the perfect snack when cramming in some last minute revision.
Whilst these foods alone do not sound overly appetising, BBC good food offer some brain functioning, healthy recipes that are budget friendly.
