The first foods that contain a lot of cholesterol can increase the risk of malignant tumors and accelerate their growth by almost 100 times, reports Science Alert referring to research by scientists at the University of California at Los Angeles.
Experts have changed the gene encoding the Lpcat3 enzyme in mice, which controls the synthesis of phospholipids from which the cell membrane forms. Earlier scientists already knew that “shutdown” of this gene increases the level of cholesterol.
As a result, researchers noticed that the growth of cholesterol also led to the growth and division of stem cells in the intestinal tissues of experimental mice.
Meanwhile, the main cause of cancer is uncontrolled reproduction of “defective” stem cells. This was also observed by scientists in the large intestines of mice after “disconnecting” the gene and increasing cholesterol levels.
Yet scientists are not ready to assert that high cholesterol affects the development of other forms of cancer.
The level of cholesterol in the body increases the products rich in saturated fats, trans fats and some carbohydrates, such as eggs, butter, meat and fish.
