Nutrition absurdities

Even among doctors, the view is common, that vegetable extracts are rich in purines and uric acid, yet these decoctions and extracts contain only traces of purines. The same doctors recommend or do not forbid drinking tea, which has often over 150 times more purines and uric acid, even from broths on bones, and what about vegetables!
Similar prejudices exist about black bread, sauerkraut. Patients are advised not to consume these products without carefully considering the background of the disease. Even in patients with the liver, dark bread, increasing bowel movement, promotes the reflex flow of bile, and in atonic constipation, black bread is simply a remedy. The same is the case with finely chopped sauerkraut, which can be usefully used in gastritis with reduced juice secretion and constipation.
An equally common mistake is to infer the amount of sugar in fruit and berries from their taste. And so, for example. sweet-tasting Napoleon apples contain approx. 7,7% sugar, while the sour Antonówka approx. 8,8%, and acid renets approx 10,4%.
Frequent abuse or misconstruction of a salt-free diet was emphasized. You have to remember, that e.g.. spinach, Red cabbage, tomatoes, contain significant amounts of NaCl. It is also worth knowing, that so promoted as a source of iron spinach, has that iron, which is used by the human system, less than tomatoes. Likewise rhubarb, despite the high calcium content, it is its wrong source, because calcium is found here in a non-digestible form.
Thus, to eat rationally, we must constantly follow the progress in the science of human nutrition, and avoid any pseudoscientific revelations.
Vegetarians' diet is gaining more and more followers, because it is free from many dangers so characteristic of other diets.
