The well-known Russian nutritionist Margarita Koroleva states that raspberry jam can, unexpectedly for many, turn out to be a product that is harmful to the body.
Raspberry jam often they see almost a cure for colds, but the Queen reminded in an interview: this product, although it contains vitamins, can still do harm. Its negative effect is associated with the presence of sugar.
“With the frequent use of raspberry jam during the cold season, not only the teeth, but also the gastrointestinal tract suffer,” Margarita Koroleva told Moscow 24.
The nutritionist clarified that products with added sugar worsen the state of the intestinal microbiome, create prerequisites for the development of candidal factors, and, therefore, the growth of fungi and other pathogenic microorganisms. These processes will have an exceptionally negative impact on the immune system.
