What fruit is the most laxative to eat? Eight out of ten people will probably answer: bananas! But why some people eat bananas, constipation is aggravated Only ripe bananas can laxative, raw bananas may have the opposite effect. Bananas contain soluble dietary fiber – pectin, pectin has the property of water absorption and expansion, which can increase the volume of feces and promote intestinal peristalsis; at the same time, the sugar content of bananas is more than 15%, which can cause the secretion of hypertonic gastrointestinal fluid, so that the water content of feces increases and becomes softer, easier to discharge. However, these effects are only ripe bananas have, because raw bananas contain a lot of tannic acid, which has a very strong astringent effect, will make the stool into a dry and hard stool, but also inhibit gastrointestinal fluid secretion and inhibit gastrointestinal peristalsis. Bananas should not be placed in the ranks of the stool food, because the stool food is containing more crude fiber, while the crude fiber of bananas is not much, the laxative effect of bananas is indeed inferior to other foods rich in dietary fiber, such as a variety of coarse grains, mixed legumes, or vegetables with high dietary fiber content, seaweed, mushrooms and various fruits with skin, but it does not completely negate the practice of eating some bananas when constipated, the key to do more The key is to eat more vegetables. Of course, if you want to choose the “top ten” laxative foods, the first in line should be: oats, sweet potatoes, red beans, corn, yogurt, seaweed, nori, celery, lotus root, bamboo shoots. In addition, eat some raw radish, raw garlic, raw onions, soybeans and other foods, to prevent constipation is also beneficial. Because they are “gas-producing food”, gas on the intestinal tract to play a “bulging” role, is conducive to increasing intestinal peristalsis, to promote bowel movements. For the elderly constipated, appropriate to eat some sesame oil and other vegetable oils can play a lubricating role, at the same time, the metabolites of fat also stimulate the role of intestinal peristalsis. Honey and sesame are also good choices.
