Bananas eat right to cure constipation, wrong eating will affect health!

The effect of bananas

Banana belongs to the genus Musa, one of the four major fruits in the world, and the most widely cultivated tropical fruit in the world, abundant in tropical and subtropical regions. It first originated in Southeast Asia and the Western Pacific, and my country is also one of the origins of bananas.

Chinese traditional medicine believes that the five colors run the five internal organs, and the yellow enters the spleen. Banana is a typical yellow fruit, and it is beneficial to eat it regularly. In addition, Chinese medicine believes that bananas are cold and sweet, can clear heat and quench thirst, cool blood and detoxify, and also promote gastrointestinal motility. "Ben Cao Qiu Yuan" mentioned in the book: "Banana to stop cough, moisten lungs and hangover, clear spleen and smooth bowel."

Modern scientific research has also found that bananas are rich in tryptophan, sugar, potassium, magnesium, vitamin A and vitamin C in addition to phosphorus called "salt salt", and also rich in cellulose and nutrition The value is very high.

Enhance body immunity and fight cancer

Swedish scholars have found that bananas can reduce the risk of kidney cancer, and emphasized that the large amounts of phenols contained in bananas have antioxidant effects. Japanese scientists have discovered through animal experiments that in addition to increasing white blood cells and improving the function of the immune system, bananas can also produce substances that attack tumor cells.


Research by Japanese scientists has shown that bananas are one of the most antioxidant foods among the foods that people often eat. While clarifying the different antioxidant capacity of banana pulp and peel, they also found the catechin, a strong antioxidant. In addition, there are studies that show that the substance that shows a strong antioxidant effect in banana is dopamine, which has a nerve conduction effect. It is known from experiments that as the ripeness of bananas increases, the content of dopamine increases. The antioxidant power of banana juice is comparable to that of green tea catechins.

Lower blood pressure

Banana is rich in potassium salts. Potassium has the effects of anti-arteriosclerosis, protecting the heart and lowering blood pressure. American scientists have confirmed that bananas contain large amounts of angiotensin-converting enzyme inhibitors and compounds that can lower blood pressure, acting in a similar way to antihypertensive drugs. Studies have shown that eating 2 bananas a day for a week can reduce blood pressure by 10%.

Eat bananas correctly

The unripe banana pulp is bitter, sturdy, and has a poor taste; at the same time, its tannic acid content is relatively large, and it is easy to cause indigestion and constipation. The mature banana pulp is soft and sweet, with a great taste and high sweetness. At the same time, the content of tannic acid will also be greatly reduced, and it will also have a good effect on intestinal and laxative.

Precautions for consumption

Should not be excessive

Eating bananas is also exquisite and should not be eaten more. Banana is cold. Excessive consumption is easy to hurt the stomach, and it is high in calories and easy to gain weight. It is recommended to eat no more than 2 roots per day.

Eat with caution in diabetics

Bananas have a high sugar content, and it has a high glycemic index, and eating it is likely to worsen the condition of diabetic patients.

Those with weak constitutions eat less

Banana is cold, it is recommended that people with weak constitution and weak spleen and stomach eat less, otherwise it is easy to diarrhea.

Cancer patients eat with caution

Many cancer patients will have symptoms of constipation after radiotherapy or chemotherapy. In addition to drug conditioning, they can also be consumed correctly under the guidance of a doctor to help relieve gastrointestinal symptoms.


At the same time, foods that contain more tannic acid will combine with iron molecules to form precipitates, preventing the absorption of iron molecules by the intestinal mucosa. Women lose a lot of blood during menstruation and need to add iron. It is recommended that women in menstruation eat as little food as possible containing large amounts of tannic acid.

Foods that contain tannin like bananas-grapes, pomegranates, tea, persimmons.

The grape belongs to the genus Vitis, with woody vines. Grapes are also rich in tannic acid, which can also hinder digestion.

Pomegranate belongs to the genus Pomegranate, deciduous shrubs or trees. Pomegranate is rich in tannins, such as tannic acid, tannic acid, etc., and can also increase constipation.

Camellia belongs to the genus Camellia, shrub or small tree. Tea contains a large amount of tannic acid. Tannin and protein synthesize astringent tannin protein, which slows the intestinal motility and prolongs the retention of feces in the intestine, causing constipation.

Persimmons belong to the genus Persimmon in the family Persimmon, with large deciduous trees. Persimmon also has the function of preventing constipation and acne. Normal people eat at most two at a time. If they eat too much, the tannin substance and astringent in the persimmon enter the gastrointestinal tract to stimulate the intestinal wall to converge, resulting in reduced intestinal secretion, reduced digestive function, constipation, or gastrointestinal discomfort.
