Although it accounts for only 2% of your total body weight, the fact remains that the brain is a food-hungry organ with ten times the appetite of other organs. In order to function, it uses up a minimum of 20% of your daily calorie in-take.
In addition to calories, you should also make sure you get good nutrients for your neurons through a balanced and varied diet. To ensure your brain gets what it needs there are certain foods you should add to your diet.
1. Oily fish (mackerel, sardines salmon…) for brain maintenance
More than 50% of brain mass is made up of lipids, and over 70% of these are fatty acids that belong to the well-known Omega 3 group. These fats are crucial to the production and maintenance of brain cells, preserving the fluidity of cell membrane.
2. Pulses (lentils, chick-peas...) for brain energy
The brain is said to be glucose-dependent, which means it uses only glucose to function. It consumes more than 5g an hour, but doesn’t know how to store it. It therefore has to be regularly supplied your diet via the circulatory system. It has long been proven that the most difficult task within intellectual performance, the capacity to memorise, depends on the level of glucose in the blood
3. Bananas for a calm brain
Rich in magnesium, which is essential in the transmission of nervous impulses, bananas are equally a source of Vitamin B6 (just one banana holds practically a quarter of the recommended daily amount).
4. Liver (veal, beef, chicken…) for intelligence
The brain accounts for around 20% of the body’s oxygen needs, and iron is needed to get oxygen to the brain by means of the blood’s haemoglobin. Liver is one of your diet’s assets guaranteed to contain this valuable metal. Equally, liver is one of the most important sources of Vitamin B..
5. Red berries for happy brain cells
All edible berries (blackcurrants, strawberries, raspberries, blueberries, blackberries etc.) are veritable mines of Vitamin C (blackcurrants have twice as much concentration in Vitamin C as kiwi fruit, and three times as much as oranges). They have antioxidant micronutrients that make up their colour (anthocyanes, polyphenols, flavonoids…)
6. Shellfish for brain function
Though rich in Vitamin B12 and in protein (notably lysine, a precursor to dopamine, a powerful neurotransmitter), it is mostly the oligo-elements in seafood and crustaceans (oysters, clams, shrimp etc.) that are good for brain function. Oligo-elements are crucial in order to fight and prevent stress and its inconveniences. Some of these can be described as ‘therapeutic weapons’ as they have a hand in fighting anxiety, mental fatigue and nervous disposition.
7. Eggs for brain connectivity
Eggs contain lecithin and phospholipids, integral to the construction of brain cell membrane. In terms of feeding intellect, their value lies mainly in the quality of their proteins. Long used as points of reference when analysing the quality of other dietary proteins by the UN Food and Agriculture Organisation (FOA), eggs are actually rich in amino acids, essential in the production of the principal neurotransmitters.
8. Spinach for good memory
All leafy vegetables share a richness in Vitamin B9 (or folates), which is known to play an active role in the development of a foetus’ nervous tissue and also in the renewal of blood cells. One of the signs of Vitamin B9 deficiency is reduced awareness and memory deterioration3. This phenomenon, observed in people of advanced age with folate deficiency, can probably be explained by the fact that Vitamin B9 is needed for the maintenance of dendrites (arborisation of neurons, where B9 levels are high).
9. Cocoa for brain stimulation
In Aztec times, cocoa was already considered a medicine. Later, Casanova, the legendary seducer of women, used chocolate as an aphrodisiac with the kind of effects we know well! Since then, the chemical analysis of cocoa paste has revealed many surprises; besides the important calorific benefits, the presence of molecules similar to caffeine (theobromine, theophylline) and amphetamines (phenylethylamine, tyramine) give chocolate its true power as a tonic and psycho-stimulant. At the same time, chocolate’s high magnesium content (330mg per 100g), and the molecules it contains which are similar to serotonin (the ‘relaxation’ hormone), account for its ‘anti-stress’ and anti-depressant effects.
10. Avocado to keep the brain young
The avocado is exceptionally rich in Vitamin E. This vitamin constitutes one of the most powerful antioxidants and protects the fatty tissues of the brain from ageing.
