The biologist warned about the dangers of kefir in diseases of the gastrointestinal tract

Kefir is considered a useful product, but it can seriously harm people with diseases of the gastrointestinal tract (GIT), lactose intolerance and allergy to milk protein. The acting dean of the Faculty of Natural Sciences of the State University of Education, biologist Irina Lyalina, warned about this on Thursday, June 17.

"Lactic acid and fermentation products stimulate the secretion of hydrochloric acid. This causes additional irritation and chemical effects on the damaged mucosa, which increases pain, heartburn and can provoke erosion or exacerbation of ulcers," the specialist said in a conversation with Lenta.Ru .

She clarified that kefir is contraindicated in people with high-acidity gastritis, gastric and duodenal ulcers, reflux disease and duodenitis. The biologist explained that with lactose intolerance, the body cannot break down milk sugar, which is manifested by bloating, cramps, diarrhea and nausea. If we are talking about an allergy to the milk protein casein, then the immune system attacks it, causing urticaria, angioedema, itching and difficulty breathing, the expert warned.

In addition, Lyalina said that uncontrolled consumption of low-fat kefir can cause chronic diarrhea and impaired absorption of nutrients, and the lack of fat—soluble vitamins A, D, E, and K in it can lead to stagnation of bile and a deficiency of healthy fats.

Kefir also changes the acidity of the environment and interacts with calcium, which reduces the effectiveness of many drugs, RT reports.

"It is necessary to observe an interval of at least two hours between taking medications and using kefir, as well as avoid low—fat products and do not drink it during exacerbations of any gastrointestinal diseases," the specialist concluded.

In turn, Ekaterina Kashukh, an expert at the Hemotest laboratory, a gastroenterologist, said that it is better to combine greens with sour cream, kefir or yogurt, as well as with eggs, cucumbers, poultry and fish in order to reduce the irritating effect of acids. 360.ru .

Nutritionist Alla Makarova told on June 11 how to diversify the summer menu. Instead of hot soups, you can choose beetroot or okroshka, and instead of heavy side dishes, hearty salads. The expert emphasized that any meal should contain proteins, fats, carbohydrates and fiber.
