First, about “ tea is also food for the body ”
It sounds strange, and so it is, but in this case, this phrase is quite applicable. The fact is that on an empty stomach you need to drink pills precisely because the stomach considers tea, like any other liquid, food . To be more precise, drugs should be taken on an empty stomach for the reason that when you have not eaten for a long time, the acidity of gastric juice is low, and the level of its production is also low, which does not interfere with the normal absorption of drugs.
What does tea have to do with it?
Moreover, Pavlov, having examined the digestive system of dogs, concluded that there are two phases of regulation of gastric juice separation: reflex and chemical (humoral). In the first, the separation of gastric juice occurs reflexively in response to the sight and smell of food, the action of food on the receptors in the oral cavity and the mechanical action of food on the walls of the stomach . The second, chemical, phase of separation of gastric juice is due to the influence of certain chemicals on the secretion of the stomach glands, but we are not interested in this.
It is mechanical irritation of the stomach walls (that is, the pressure of food or liquid on them) that increases the production of gastric juice, and that is why, when drugs are to be taken on an empty stomach, you should not drink before taking and other liquids in large volumes. The stomach cannot distinguish what is pressing on its walls: two large potatoes from poppy seeds or half a liter of tea, drunk in front of the computer, and equally triggers the production of gastric juice.
So, you can drink the rest of the medicines with tea?
Not allowed. The fact is that tea contains a lot of substances called tannins. This is a group of phenolic compounds containing a large number of —OH groups. Tannins have a characteristic astringent taste and tannin properties that are based on their ability to form strong bonds with proteins, polysaccharides and other biopolymers. Tannins form insoluble compounds, and many drugs simply precipitate and are not absorbed. Tea should not be taken with especially nitrogen-containing drugs: caffeine, papaverine, codeine, aminophylline.
Who said that? First of all, you need to understand how you need to take these pills: before meals, after meals, during meals or on an empty stomach. From here and you need to start, that is, you ate on an empty stomach or before a meal, then you should not drink tea, because for the body, tea is also food.
