The benefits of fiber have long been known to anyone who is even slightly interested in healthy eating. The words "fiber" and "weight loss" have become almost synonymous in modern dietetics; fiber is a fairly coarse plant food that normalizes the functioning of the gastrointestinal tract. In the course of oncological studies, it was found that people who consume large amounts of fiber in food are less likely to develop a disease such as bowel cancer. Recently, scientists have conducted a number of studies and found that a diet that includes a high fiber content in food can help slow the development of prostate cancer.
Prostate cancer is a serious disease that mainly affects middle-aged and elderly men. In many European countries, reports from medical institutions show that prostate cancer has become one of the three most common diseases among adult males. Like any other oncological disease, prostate cancer is difficult to treat and often leads to the death of the patient. A characteristic feature of this disease is that in a favorable environment, cancer cells quickly become aggressive and spread to other tissues.
Scientists from the University of California (USA) have discovered that, according to statistics, prostate cancer and colon cancer are mainly found in European and North American countries. In Asian countries, these diseases are less common. Doctors have suggested that the reason may be hidden in the different diets of people on different continents. As is known, Asians have long preferred plant foods, which are rich in both vitamins and fiber. Accordingly, doctors decided to conduct a series of experiments and find out: what effect on the body and separately on malignant tumor cells can substances found in fiber have. As is known, fiber contains large amounts of B vitamins and inositol hexaphosphate.
Scientists have conducted studies on small rodents, which now allow us to state with certainty that the consumption of fiber can affect the development of oncological diseases, or more precisely, the development of prostate cancer. The experiments consisted of the fact that initially a fairly large number of white mice were artificially induced to develop prostate cancer, then half of the animals were injected with substances contained in fiber. Using tomography, doctors monitored the development of cancerous tumors and soon noticed that the animals that were supplied with B vitamins and inositol hexaphosphate had a slowdown in tumor growth in their bodies and, in some cases, even a reduction in the malignant tumor.
The head of the research team claims that the substances contained in fiber are capable of blocking the blood supply around the cancerous tumor, making its development impossible. Cancer cells need constant nourishment and cannot multiply without a stable supply of oxygen.
