I gave up sugar for a year completely. It was a successful experience. I agree that at first we notice that many of the products we are used to have sugar (even not sweet in taste). The most important thing is to take responsibility for the search and selection of food products or ready-made meals, learn how to independently read the composition, energy tables on labels; as well as to study what sugar and its analogues are. For example, a sugar molecule is made up of one glucose atom and one fructose atom. That is, glucose, glucose-fructose syrups, invert syrup, molasses, molasses and many other names are the same sugar.
Here it is important to generally understand why and for what purpose you want to give up sugar, since, for example, fructose in some cases has a more serious negative effect on the body than glucose or sugar; and starches and flour (any grain) in the body are broken down to glucose in any case.
Nowadays there are a lot of sugar-free food on the market and it is diverse, so knowledge, diet control and conscious (!) food choice will help you to live peacefully without sugar.
Ditching sugar altogether is a little pointless, but reducing its amount in food is really important. In addition to the obvious sugar, I advise you to avoid these foods:
Quick oatmeal bags, "fitness" bars, store granola and other things that are sold under the guise of superfood and healthy yummy (this is not worth eating, not only because of sugar).
Some condiment mixes.
Dairy products (not those with milk sugar aka lactose, but with sugar-sugar, such as curds and yoghurts).
Suddenly baby food. :( Food from 4 months often contains dofig sugar, however, as well as mixtures (but not all).
There are many products without added sugar, including basic ones: fruits, vegetables, meat, cereals. No one has ever died without store loaves and sauces, and you can mix the same spices yourself. Everything is replaceable)
There is no need to exclude fructose, lactose and glucose without medical indications, I think you know about this.
It is not entirely clear what exactly is meant by "everywhere".
Get rid of only added sugar
There is no sugar in meat, no in fish, almost no in raw vegetables, no in unprocessed cereals (rice, buckwheat, semolina, etc.), almost no in basic dairy products (milk, kefir, cheese, cottage cheese, sour cream, butter, etc.), vegetable oils.
Added sugar (only natural) is not found in fruits, nuts
There is no sugar in the water, it flows from under a tap without it.
These classes of products are used to build a healthy diet, all of them are available in stores, no special problems are seen, except with quality.
It is enough to give up the sweetest foods. These are pastries, sugary drinks, sweet yoghurts, sauces, rolls and sweet bread. Otherwise, if there is sugar, it will be in insignificant quantities and it will not harm you.
There is only one answer - to cook your own food. Depending on your skills and lifestyle, this can be both difficult and completely doable. Well, or let your partner, spouse, with whom you live there cook for you. Also an option. The store is full of products without sugar, sometimes even without salt, without other preservatives. But there is always a category of products in which there is nothing without sugar. Then just take the raw material and cook it yourself. For example, I could not find seaweed without sugar and salt. Awful number of items in the supermarket, but everyone has something, and they also like to shove vegetables there, mayonnaise. Option one - buy kelp, or any other seaweed, fresh or dried, and pickle them yourself. Although, I repeat, in large stores and supermarkets there are whole rows of healthy food, where everything is organic, unrefined, without sugar (instead, glucose, fructose or stevia), without yeast, etc. etc. I see one drawback here - the price is clearly higher.
