Controversial benefits: 5 “healthy” foods that can be harmful

There are no exclusively healthy food products, just as there are no exclusively harmful ones. These products are considered healthy, but they have some features that make their benefits for someone very controversial.Yogurt, cheese огурт "Активиа".Источник фото: 123rf.comThese fermented milk products are rich in B vitamins, calcium and iodine. But fermented milk products also contain the most harmful of fats - cholesterol. The insidiousness of yogurt and cheese is that if the fat content of the product is reduced (relevant for those who prefer yogurts with a low percentage of fat), then calcium absorption deteriorates. And the protein casein contained in milk and products made from it is contraindicated for older people - it is poorly absorbed.Coffee Кфе с мороженымИсточник фото: 123rf.com/profile_natalyastepowayaMany find it difficult to imagine their morning without a cup of coffee, and some continue to drink this drink throughout the day, wanting to get a boost of energy. And this is not good. Coffee is rich in caffeine, which blocks a special enzyme that breaks down the “carrier” of hormones into cells. As a result, the effect of hormones (for example, adrenaline) on the body increases, and some other processes associated with the influence of hormones are disrupted. For example, the secretion of gastric juice containing hydrochloric acid increases. Heartburn or even stomach pain may occur. Against this background, tachycardia also occurs - this is why coffee is not recommended for people with cardiovascular diseases. Among other things, coffee has a diuretic effect, which can cause dehydration. It is not recommended to overuse the aromatic drink; the optimal amount is two small cups of coffee per day.Wholemeal bread Пшничный хлебИсточник фото: prozaThis bread is made from wheat flour with an admixture of crushed wheat grains, which do not go through the shelling stage. The shell of the grains, on the one hand, makes the bread less caloric, on the other hand, it adds lectins (including, for example, gluten). Lectins attach to intestinal cells and disrupt gastrointestinal functions. As a result, food digestion processes are disrupted and allergic reactions occur. Gluten allergy is one of the most common allergies today.Green tea зелный чайИсточник фото: ru.freepikThis type of tea contains antioxidants, which are definitely good for your health. But drinking tea too often leads to a number of problems with the gastrointestinal tract. The above antioxidants are easily converted into theanine. Under the influence of hot water it turns into tannic acid. It thins the gastric mucosa, causing gastritis, ulcers and even oncology. Therefore, tea lovers should adjust their drinking rate - no more than one cup per day and not on a daily basis.
