1. A banana is actually a berry. People often think of berries as small, soft fruits that can be plucked from plants, but botanically, berries are fruits that grow from one ovary of a flower and have multiple seeds. The berries have three distinct fleshy layers: exocarp (outer skin), mesocarp (pulp), and endocarp (the innermost part that holds the seeds). Bananas are berries precisely because they meet the above conditions.
2. The inside of the banana peel can be used to relieve itching and rash after mosquito bites. Banana peels contain a substance called banana shell, which inhibits the growth of skin bacteria and fungi. In addition, banana peels also have a certain amount of edible value, but it is best not to eat them for people with kidney disease and diabetes.
3. Bananas are naturally slightly radioactive. The radiation of bananas is related to their own rich potassium content. But don't panic, any talk of radiation hazards out of dose is unscientific. The amount of radiation in bananas is simply not enough to cause cancer, and supplementing the right amount of potassium is essential for the human body, and the lack of potassium can lead to abnormal heart rate and even a series of problems such as cardiac arrest. So please feel free to eat bananas boldly, even if you eat too much, the body's metabolism will control the potassium content in the body and excrete excess potassium.
4. The most primitive bananas have little edible value. Unlike modern bananas, which have been cultivated after years of artificial research, the original banana seeds were large (now banana seeds are almost degraded), with few edible portions and astringent taste. But after a hundred years of research and cultivation by scientists, banana varieties and tastes are becoming more and more abundant, and more than 150 countries around the world have grown bananas, and bananas have become one of the common fruits on the table. (A little fact: The world's largest banana producer is India, and the largest banana consumer is China.) ）
5. Bananas contain naturally high levels of tryptophan and dopamine, which can help improve mood and enhance brain function. It also contains essential vitamins and minerals such as vitamin C, potassium, and magnesium.
