Put aside bananas and eat bananas together
Banana is a tropical and subtropical fruit. Because it is sweet and delicious, and inexpensive, it has become one of the most popular fruits for all ages.
The types of nutritional ingredients contained in bananas are not special compared to other fruits, but the content of some nutritional ingredients is somewhat special: high sugar.
Bananas are particularly high in carbohydrates (sugars).
The sugar content of 100 grams of bananas is about 28.
9 grams, other fruits such as apples, pears, watermelons and other sugar content of about 10 grams.
The sugars contained in bananas are mostly monosaccharides and disaccharides.
High in potassium.
Bananas are also particularly high in potassium.
For every 100 grams of fruit, the potassium content is about 330 mg for bananas and lower for other fruits, such as about 119 mg for apples, 92 mg for pears, 166 mg for peaches, 104 mg for grapes, and 87 mg for watermelons.
Banana dietary fiber content is higher.
Usually about 1 gram of dietary fiber per 100 grams of fresh fruit, while bananas are 3.
It is these differences in ingredients that make bananas show special effects: laxative, intestines, lowering blood pressure, and replenishing energy.
Laxative and intestinal laxative laxative generally contains two meanings: relieve constipation and relieve diarrhea.
On the one hand, banana supplements dietary fiber, absorbs water in the intestine, swells the stool, and is easy to discharge. At this time, the intake of water should be appropriately increased; on the other hand, increasing dietary fiber during diarrhea can absorb water in the intestine and reduceSymptoms of diarrhea.
It should be noted that only ripe bananas have a laxative effect.
When the banana is immature, the skin is greenish-green, the flesh is hard, and it tastes astringent and tasteless; after ripening, the meat is soft, sweet and smooth.
Why is there such a big difference in the taste and texture of bananas before and after maturity?
This is because the banana composition changes during the ripening process.
Unripe bananas contain large amounts of starch, pectin and plant acids, especially tannic acid.
If there is more starch and pectin, the taste will be hard, and if tannic acid is more, the taste will be astringent.
Tannic acid has a strong astringent effect, so if you eat unripe bananas, it will make your constipation worse.
During the ripening of bananas, part of the starch is broken down into short-chain sugars, including polysaccharides, monosaccharides (such as glucose), and disaccharides (if sugars), while tannic acid gradually decreases.
Decomposition of starch makes the flesh sweet and soft, while reducing tannic acid removes astringency.
Lowering blood pressure Sometimes hypertensive patients go to the doctor, and the doctor will tell them: eat a lighter diet, eat bananas, apples, etc., which can help lower blood pressure.
Does banana really have a blood pressure lowering effect?
Dietary high sodium and low potassium is one of the important causes of hypertension, which has been recognized by most scientists in the world.
Excessive sodium intake is the clear cause of hypertension, and sodium plays a role in inducing and aggravating the disease during the course of hypertension.
One of the important measures to prevent high blood pressure is to limit the sodium salt in the diet.
And potassium in the human body can counteract the adverse effects of sodium and have the effect of lowering blood pressure.
Nutritionists have repeatedly emphasized that eating more fruits and vegetables to supplement potassium deficiency can prevent high blood pressure.
It must be reminded that when taking potassium-preserving diuretics, it is best not to eat bananas and other fruits with high potassium content to avoid hyperkalemia.
Replenish physical strength Watching competitive games, sometimes you can see athletes drinking water and eating bananas during halftime.
What effect does eating bananas have during physical exertion?
This effect comes from the content characteristics of banana nutritional content.
On the one hand, bananas have a high sugar content, and the monosaccharides can be quickly absorbed and replenished. Disaccharides and polysaccharides can be slowly absorbed and maintain physical strength.More, sweating a lot during exercise, potassium loss is obvious, it is easy to cause hypokalemia in the body, hypokalemia can make people feel tired, fatigued, muscle cramps, which is not conducive to the game.
Therefore, bananas are a good way for athletes to quickly replenish energy during the game. Due to the high sugar content of bananas, people with diabetes must pay attention to eating bananas. However, bananas must not be eaten. Instead, if you eat more bananas, you should reduce the amount of meals to maintain the excess balance of sugar in your daily diet.
Furthermore, eating a small amount of bananas has little effect on blood glucose changes, because the addition of fiber can delay the absorption of sugar.
Editor’s note: Bananas are delicious and have many benefits. At present, the rumors that “bananas cause cancer” have caused their prices to drop sharply. It can be said to be economical and beneficial.
