I often hear doctors forbid people sweets, coffee, alcohol for various illnesses, saying that it is all from the evil one. Let's figure out what from this list is from the evil one and what is not and why:
Let's start with sweets, i.e. fast carbohydrates, this is the simplest source of energy for body cells. If there are no metabolic diseases where glucose is high (periodically more than 5.5 mmol / l in serum), then sweets can be eaten every day.
With low glucose in serum (~ less than 4 mmol / l), sweets even become a medicine. For example, symptoms of low glucose are spontaneous loss of consciousness (usually occurs in thin girls), frequent nightmares and waking up at night with a feeling of hunger.
I will also add that you need to avoid fructose in its pure form, it leads to fatty liver (for example, laboratory rats are created with such a pathology by feeding fructose powder).
Speaking of coffee, the benefit here is as follows - ground coffee in the morning is an excellent means of increasing intestinal peristalsis .
What is it? This is a contraction of the muscles around the intestines for accelerated passage of contents. If you combine coffee in the morning with something fatty (for example, a French breakfast - a roll with butter ), then in addition to peristalsis, you can increase bile secretion. These two processes contribute to the removal of "waste", in particular, they help detoxification (although there is an exception for people with Gilbert's syndrome).
Also, coffee bean particles inside the intestines are an excellent "house" for beneficial bacteria, i.e. a prebiotic. Therefore, it is important to drink ground coffee, not instant!
You should also remember that during the production of coffee, it is processed with all sorts of chemicals! Therefore, preference should be given to "major" brands of coffee.
Well, as for the caffeine in coffee, you know without me that it is a stimulant and you can't have too much, otherwise you will be twitchy.
As a result, the only possible harm is in caffeine and in chemical processing during production.
Now the most interesting part . Alcohol. I'll tell you right away that there is no objective benefit here. You probably know that ethyl alcohol washes away fat, you've probably all washed your windows with a similar product and seen how this happens.
So, every cell in our body has fats (lipids) on its surface, and quite a lot of them. When drinking alcohol, the cell surfaces dissolve, and the closed structure of the cell is disrupted, substances that should not normally get into it begin to enter. And this happens in all tissues (the vasodilating effect is also from here).
But the most interesting processes occur in the brain. Alcohol removes the lipid layer from the membrane of neurons, just like some girls take off their clothes under it.
As a result, all kinds of neurotransmitters that control our behavior enter the bodies of neurons. With small doses of alcohol, this is dopamine (roughly speaking, a feeling of motivation), serotonin (roughly speaking, a feeling of joy and happiness), with large doses, this is GABA or gamma-aminobutyric acid (inhibition).
Well, all this gives that same high for which people drink or, God forbid, get drunk . High is, of course, occasionally good, BUT at the same time the nucleus of cells and the DNA in it are damaged. That is, people who drink often create mutations in their DNA. As a result, alcohol is harmful, it damages cells and DNA, but it is unlikely that this information will make anyone completely give it up.
