If IBS has pain syndrome and (or) constipation, then the diet should be physiologically complete, taking into account the normal content of carbohydrates, proteins and fats, increasing the amount of vegetable fats. It is necessary to exclude from the diet dishes and foods that enhance the processes of fermentation and putrefaction in the large intestine, extractives, products that are rich in essential oils, as well as cholesterol; in turn, products are added, in which the amount of dietary fiber is increased (millet, buckwheat and pearl barley). Speaking about the calorific value, we can say that it should be approximately 2500-2800 kcal.
Particular attention must be paid to nutrition in IBS, if diarrhea prevails. At a time when there is an exacerbation, the diet should be present in the right amount of protein. It is necessary to exclude refractory fats and, of course, products, tolerance to which is reduced. It is clear that from the diet it is necessary to completely exclude products that have a debilitating effect (prunes, honey, beets, carrots and other raw fruits and vegetables). If you suffer from flatulence, exclude cabbage, legumes, other foods that contain easily digestible carbohydrates. You should forget about beer, bananas, nuts, raisins, grape and apple juices. Sorbitol and fructose can also contribute to flatulence, which are added to medicines and dietary products, which are very rich in berries and fruits. In principle, the diet can be quite normal, given only that the number of meals should be 4-6, and at night there is absolutely forbidden. Very often, IBS is accompanied by lactose intolerance (the so-called lactose deficiency). In this case, the diet for RK syndrome should not include most dairy products.
There is no doubt that there are certain mechanisms that support and enhance the symptoms that are characteristic of intestinal dysfunction in irritable bowel syndrome with diarrhea. Many of them are underestimated and, unfortunately, are not used in the SRK. These include the formation of trends that are resistant to lowering the level of digestive supply and nutritional balance, significant, which are almost inevitable with very limited opportunities to organize proper nutrition for such patients. Now it is proved that the morphofunctional state of the integumentary epithelium of the intestinal tube is associated with deficiency of such fatty acids as omega-3 and omega-6, magnesium, zinc, vitamins. Patients are pathologically afraid of any food, so they try to limit not only the whole range of products, but also the number of them in your diet, which often leads to nutritional disorders (chronic), and also on the basis of "vicious circles" of pathogenesis. Secondary immunological failure is one of such manifestations. In this case, many authors advise adding to the diet of patients with dietary supplements that contain omega-3 and omega-6 fatty acids, as well as some trace elements.
Development of indications for therapy with fibers that are food, remains very acute and not solved until the end of the problem in medicine, and to be precise - in gastroenterology. Very few clinical studies related to the evaluation of the effectiveness of dietary fiber in IBS. And the results are very contradictory.
If we talk about IBS with constipation, the patient's diet should be enriched with indigestible PV (hereinafter - dietary fiber), which improve intestinal motility (prokinetics); IBS with diarrhea - in the diet should be more water-soluble PV (pectin).
Studies of recent years have shown that PV, depending on their qualities, have different effects on the person's chair. Cereals, fruits and vegetables are advisable to use in irritable bowel syndrome with diarrhea. There is also such a (water-soluble) fiber such a positive function as detoxification. The so-called "broom effect". Simply put, elimination of toxins from the body.
At the present time in Japan, they are trying to develop a technology for obtaining these very PV from soy. If you add PV to food, they will not change the organoleptic properties of drinks and products, but will only give them their properties.
If IBS with constipation, then save the picture will help wheat and rye bran, roots and algae, cereals and fruits. And if we talk about commercial preparations, we can mention fibromed, microcrystalline cellulose or eubicor. All these drugs accelerate the transit of the intestine. Also suitable for individuals who do not suffer from IBS, but who have trouble with situational constipation. But, you should not get involved, you can cause flatulence.
