Junk food hurts the whole body: We summarize recent foreign medical websites about the different degrees of damage caused by junk food within 10 days. To summarize, there are several points: damage to the sense of taste. Junk food such as sweetened beverages, fried, convenience and fast food can harm children’s sense of taste and cause anorexia.
Disrupt metabolism. A study in the journal “Obesity” showed that junk food can affect metabolism, 12 healthy college boys ate high-fat food for five days in a row, the muscle will be glucose into energy efficiency is significantly reduced, this change is easy to lead to metabolic disorders. Food deterioration during storage and transportation, such as green skin red meat fish produce histamine, which can lead to histamine poisoning Carcinogenic substances: toxins produced during food processing, such as barbecued foods produce carcinogens heterocyclic amines, polycyclic aromatic hydrocarbons, acrylamide, etc. Eating too much oil as a child can lead to cancer as an adult: A recent U.S. study shows that for adolescents, especially girls, a high-fat diet may increase the risk of breast cancer and even accelerate the development of breast cancer. A high-fat diet can accelerate the inflammatory process and encourage cancer cells to proliferate.
Disrupting the balance of intestinal flora. Scientists have recently found that feeding mice high-fat food changes the composition of the intestinal flora, increasing the reproduction of certain pathogenic bacteria and reducing probiotics, preventing the intestine from sending neural signals to the brain to “eat, stop eating”, leading to overeating and affecting the digestive health.
Damage to the liver: recent newspaper reports, often eat fried food will appear similar to the symptoms of hepatitis, eat fried food for a month, can cause significant changes in the liver, triggering an increase in transaminases in the body. The reason for this is that the fried food, so that essential fatty acids, as well as the protection of the liver nutrients vitamin A and E are destroyed, producing chemically active free radicals, thus damaging liver cells.
Impact on children’s intellectual development: British researchers followed 14,000 children over many years and found that children who ate junk food before the age of 3 may have lower IQs than their peers. A new study recently published in the American journal “Clinical Pediatrics” reported that children who regularly eat fast food such as McDonald’s, KFC and Pizza Hut do not do as well in school as other children. The study used data collected from 8,544 U.S. students, recording their fast-food intake at age 10, and then compared the data to their reading, math and subject scores at age 13. The results showed that children who never ate fast food scored an average of 83 in all subjects, while those who ate fast food every day scored an average of 79. The theory behind this phenomenon is that a diet based on processed foods lacks vitamins and other elements that are essential for brain development, resulting in slower brain development, and that the trans fats in processed foods can seriously damage memory.
Easy fatigue and laziness. Eating foods high in sugar means a rapid increase in blood sugar, which stimulates the release of insulin and mobilizes the body to consume glucose rapidly, followed by a dramatic drop in blood sugar, which can cause fatigue and irritability. New research shows that unhealthy ingredients in food and low nutrients also make people more immobile and lazy.
Narrower arteries. Eating fast food can quickly damage arteries. A Canadian study showed that a perfectly healthy man who ate a meal high in saturated fat had his artery walls narrowed by 24 percent two hours after the meal, which could lead to high blood pressure and potential heart problems.
Inattentiveness. Researchers at Cambridge University found in mice experiments that a 9-day high-fat diet caused the mice to make more mistakes while walking a maze, suggesting that junk food may disrupt concentration and make it impossible to concentrate.
It makes people ugly. A new study in the journal Immunity shows that high-fat foods may make people look ugly. Mice fed high-fat food had changes in skin proteins and internal inflammation that made them look swollen, which researchers say may explain why they woke up swollen the next day after a night of partying.
Addictive. Studies have shown that foods high in sugar stimulate the release of dopamine, a brain chemical that gives people a sense of satisfaction and addiction, and they want to eat again.
