You probably know yourself that there is nothing absolutely harmful and useful in life. There is only a scale of harm and benefit, if harm or benefit outweigh each other, then we can talk about usefulness and harm. Any bread is harmful in large quantities, any scientist or fitness trainer will tell you this. If you personally like to eat it, then no problem, the main thing is to observe the measure. And leave any speculations about the mythical huge harm to pseudo-scientists, who will intentionally multiply any harm by 100 in order to achieve their goal, and more often the goal of a competitor's company.
The composition, as well as almost all bread on supermarket shelves, contains sugar and yeast.
Baker's yeast is terphomilic fungi that do not die at high temperatures and enter our body, for a long time "prescribing" in the intestines. The products of their vital activity constantly in the background poison the intestinal microflora and contribute to the spread of pathogenic bacteria in it.
Sugar in combination with flour also triggers the fermentation process in the intestines, increased gas production and the synthesis of toxic substances, like any fermentation process - read rotting. Sugar in our body is relatively normally absorbed only out of combination with other proteins, fats and carbohydrates. With other products, he inevitably wanders. In addition, it lowers the acidity of gastric juice, which further complicates digestion, in fact, forcing food to lie in the stomach for a long time undigested and the same down the intestines, disrupting the work of all organs of the gastrointestinal tract.
From available bread, in which no yeast or sugar - only "Lyonskiy" from VkusVilla can be noted. Tastes quite decent. Or any raw bread - very tasty too, but the price tag is much higher.
No, not harmful. The only thing is that soy flour is thumped into it, which is kind of bad, and apparently palm oil, at least the origin of vegetable oil, which is indicated in the composition, remains vague. On the good side, this is certainly not white bread, but it is not harmful, perhaps not as useful as other varieties, but not harmful.
