what are the benefits of bananas?

Very popular in France, banana is the second most consumed fruit today Apple. Indeed, every year “we consume an average of 500,000 tons of bananas per year, ie 8-10 kilograms per capitaall ages together,” biochemist Isabelle Brette writes in her book Alpen has launched Discover the Virtues of Bananas.. According to recent surveys, 40% of the French even say that they cannot do without it.

Highly nutritious, banana is one of the most energy-giving fruits. It is also rich in carbohydrates, vitamins, fiber and minerals, making it an essential health asset.

Banana protects your heart

Lots of potassium, a banana could guard your heart according to a study published in the journal JC Insight. Indeed, researchers from the University of Alabama in Birmingham (USA) have proven thisa diet low in potassium would promote calcification and hardening of the arteries. To obtain these results, the researchers divided the mice into three groups. They were then fed a diet with more or less potassium. As a result, those on a potassium-deficient diet had more calcifications in their arteries. And vice versa, mice fed a higher potassium diet had fewer calcified arteries.

As a reminder, the daily need for potassium is 3.5 grams (at least) according to health care authorities. “Overall, a diet rich in fruits and vegetables provides sufficient potassium, and there is very little fat,” writes Isabelle Brette in her book. However, according to Ciqual’s food composition table, “Bananas, with 385 mg of potassium per 100 g, are one of the richest fruits in potassium.

Bananas reduce high blood pressure and stroke risk

In her book, Isabelle Brette also highlights several studies that prove thislow potassium intake can increase the risk of high blood pressure. “Increasing potassium intake is as important as a low-salt diet in managing hypertension,” she says. “When potassium intake is high, the body excretes more sodium and water. On the contrary, when potassium intake is low, the body retains more sodium, which can increase blood pressure. In short, a diet rich in potassium acts as a diuretic,” summarizes the American scientist.

It’s the same as bananas help reduce the risk of cardiovascular disease. because, high blood pressure is responsible for more than half of cardiovascular disease and more than half cerebrovascular accident (CVA). This is also proven by the scientists of the nutrition department of the World Health Organization (WHO). Indeed, according to them, Eating a banana a day can reduce the risk of stroke by 24%..

Bananas protect against certain forms of cancer

Bananas are said to prevent certain types of cancer because they contain antioxidants and fiber. This is especially true of kidney cancer. Indeed, to support her observations, the author gives as an example a prospective study of 61,000 Swiss women between the ages of 40 and 76. Based on the results of this study, the highest banana consumers would have the lowest risk of developing this disease. According to the hypothesis presented by the scientists, the antioxidants in bananas are the reason for this protective effect. and more specifically dopaminevery much in bananas.

Eating bananas would also reduce the risk colon and rectal cancer according to a study in Uruguay. “Fruits and vegetables would reduce the risk of this colon cancer due to their high levels of vitamins, minerals and antioxidants,” says Isabelle Brette.

Do not throw away overripe bananas

Of course, it is less attractive when the banana is covered with black spots and reaches the final stage of ripening, it may become an anticancer agent. “When very ripe, a banana produces a substance called TNF-alpha (tumor necrosis factor). Because of its ability to fight abnormal cells, it plays an essential role in the fight against cancer, based on research conducted by Japanese scientists,” reveals Isabelle Brette. “This substance, they say, would increase the powers of the immune system by increasing the number of white blood cells.” So the more dark spots, the greater the immune and anti-cancer power.

Eating bananas regularly is good for your brain

Among the many benefits, banana is one of the foods that can improve our intellectual performance. It’s thanks to him high magnesium content, necessary for the transmission of nerve impulses. This fruit too an excellent source of vitamin B6, which plays a specific role in the functioning of the central nervous system. Indeed, it specifically allows the production of certain neurotransmitters, “such as serotonin, GABA (gamma aminobutyric acid), … which have certain effects on our mood,” the author writes in her book.

As a reminder, vitaminsand especially B groups, are necessary for the proper functioning of the brain. “It has been proven that the energy metabolism of the brain is significantly activated during the learning period. Synthesis of proteins and neurotransmitters increases, so vitamin intake should be increased accordingly. Eating fruits like banana…” advises Isabelle Brette.
