Green tea, in addition to having a tonic effect, contains the rare amino acid L-theanine. This substance acts as a neurotransmitter - it transfers electrical impulses between cells in the body, including from nerve endings to the brain. Green tea can help reduce anxiety and relieve depression. L-theanine improves performance and cognition in the brain by increasing blood flow. Please note that green tea can lower blood pressure, so it is not advised to drink it in the morning on an empty stomach.
Eggs contain many vitamins, including B12, as well as choline. The latter plays a role in protein synthesis and is a neurotransmitter. A study by a group of scientists from the Norwegian organization Hordaland Health Study confirmed that students who ate large amounts of choline in their meals improved their grades significantly. Choline deficiency leads to decreased cognitive function. Vitamin B12 also has a positive effect on memory capacity and regulates blood sugar levels.

Fatty acids - lauric and capric - make coconuts and unrefined cold-pressed coconut oil very beneficial for the brain. They help its cells fight aging, improving their performance. Coconut oil is recommended for the prevention of Alzheimer's disease. It is not necessary to eat butter with spoons, it can be added to cereals or fried in it instead of vegetable oil, and also baked at low temperatures.
Cedar oil is produced from Siberian pine seeds. When cold pressed, the maximum of nutrients is preserved. Hot pressing and chemical extraction are also used to make oil. In the first case, the product loses some of its healing properties, and the chemical method can even make it harmful, so the oil obtained in this way should not be used for food. Cedarwood oil contains omega acids, vitamins A, D, K, B vitamins, vitamin C, magnesium, sodium, phosphorus, calcium. They improve the functioning of the central nervous system. In addition, cedar nut oil contains many phospholipids involved in the formation and development of brain cells.
Lentils contain a lot of vegetable protein and folic acid, iron and B vitamins. These elements support the course of biochemical processes in the brain, improve memory and reaction speed. Iron helps provide the brain with oxygen, which is important for concentration and fighting fatigue.

The founder of the Nootropics Expert information portal, David Tomen, has been studying nootropics for more than ten years - substances that affect mental functions, including the ability to remember and understand. He cites avocados as one of the important neurostimulant foods because of their pantothenic acid (vitamin B5) content, which is responsible for long-term memory. The acid is also found in dairy products, mushrooms, sweet potatoes, shellfish and fish, but in much lower quantities. Lack of pantothenic acid leads to fatigue, depression and dyspeptic disorders. Regular consumption of this vitamin helps in the production of antibodies that protect the brain from harmful substances.
Spinach holds the record for lutein content among all vegetables and fruits. It is necessary for the prevention of eye diseases, slows down degenerative processes in the brain. In addition, spinach is high in folate (vitamin B9), which improves memory and cognitive function. Spinach is best eaten fresh, as heat treatment reduces the beneficial properties of this plant.

Chocolate is made from cocoa beans, but for memorizing material or working on a serious project, it is better to choose a cup of cocoa without sugar. Cocoa is considered a nootropic drug. The drink contains many nutrients for the brain, including magnesium, flavonoids and tryptophan. Magnesium acts as fuel for cells in the body, relieves anxiety and helps to focus on business. Flavonoids in cocoa help to strengthen and dilate blood vessels, thereby increasing blood flow and the brain begins to work better. Research by Professor Franz Messerli, published in the New England Journal of Medicine, confirms that regular cocoa consumption improves memory. In his work "Drinking chocolate, cognitive function and Nobel laureates," the scientist argues that in countries where a lot of cocoa is consumed,most of the winners of the prestigious award were born.>
