If you are healthy, your blood glucose level is normal, there are no other health problems for which you should limit sugar, then on the so-called proper nutrition, there is no particular need to limit sugar
Natural talkativeness makes Eugenia's answer to be supplemented) There is some excessive anxiety about food in general, and especially sugar. Calm down?)
1a When the words "sugar" and "carbohydrates" are mentioned, sweets, soda and other caramels pop up in my head, but not millet or oatmeal, not beans and not carrots.
1b Addition: lactose (oh no, milk, why not!), glucose, fructose and sucrose are sugar. Those. and honey. And stevia. And ... you get the idea, right?)
1c The more active your life (and therefore you yourself), the more carbohydrates you need. Sport? We need carbohydrates! Fatigue? We need carbohydrates!
Calm, no reason to panic) It's just important from which sources you will receive it. Sources of "sugar" are refined and sometimes not. When you eat carbohydrates, they break down and sugars enter your bloodstream. The body spends a lot of energy to keep the amount of glucose in the blood at the same level (= not jump), when you eat unrefined carbohydrates, you help it solve this problem. And if you eat refined, then you interfere, because this level soars to heaven. Well, or above the horizon, for example. And then just as quickly it goes below the horizon, and you need to restore balance - and therefore you want to eat very much.
They talk about an interesting phenomenon: with a strong decrease in blood sugar, the body turns on the stress mode and the level of cortisol rises. And cortisol is an increase in blood glucose in any way, even if there are no carbohydrate sources.
In general, according to WHO recommendations, complex carbohydrates that help remove these swings should be about 45-60% of the total diet: these are all kinds of whole grains, cereals and it is better to give preference to not too processed / crushed ( spelled, wheat, oatmeal, green buckwheat (or regular), all types of unpolished rice, oatmeal for cooking, millet, barley, durum wheat pasta or whole grains, ptitim, couscous, quinoa).
And don't forget about vegetables and fruits!)
It is worth, perhaps replacing it with stevia syrup - it is good for the body, it is similar to sugar and is not. In the modern world, sugar is put literally everywhere, and the transition of mankind to the general use of sugar in large quantities occurred not so long ago, that is, a person is not evolutionarily adapted to the consumption of such a volume of sugar. Of course, a person needs carbohydrates, so you need to eat fruits and vegetables, because they also contain sugar, but in a reasonable amount for a person. Sugar interferes with normal metabolism, fat burning. It badly affects the performance of a person, being a kind of drug. It is recommended that you eat no more than 4 teaspoons of sugar a day, including sugar in foods and drinks. I recommend watching the recently released documentary "Sugar", it talks about the effects of sugar in detail and in an accessible way.
Granulated sugar and all products that contain it (sweets, cookies, etc.) can be safely excluded without consequences for the body, since the body processes into glucose, which is necessary for the functioning of the brain and in general, any carbohydrates (porridge, bread, fruits).
More likely no than yes. Sugar is an integral part of our diet and belongs to disaccharides. Carbohydrates generally perform many functions in our body, so sugar cannot be excluded. Another thing is, if you consume a lot of it, then you need to lower this level. Remember that in addition to the granulated sugar that we put in tea / coffee, there is sugar in fruits, vegetables, groceries, drinks, etc. For the normal functioning of our body and metabolism, in particular, it is necessary to consume 4-6 teaspoons per day, not counting sugar in foods.
