The Hazards of Junk Food on Children's Health

The Hazards of Junk Food on children's Health

Junk food inflicts harm upon the entire body. Summarizing recent information from foreign medical websites, it is evident that consuming junk food continuously for ten days can cause varying degrees of damage to the human body. In summary, the following points highlight its adverse effects:

(1) Impairing the sense of taste. Junk food such as sugary drinks, fried, processed, and fast food can harm children's taste buds, leading to loss of appetite.

(2) Disturbing metabolism. Research published in the journal "Obesity" indicates that junk food affects metabolism. After consuming high-fat food for five consecutive days, the efficiency of muscle glucose conversion to energy decreases significantly, leading to metabolic disturbances. Food spoilage during storage and transportation can result in the production of toxins, such as histamine in improperly handled fish, causing histamine poisoning.

(3) Carcinogenic substances. Toxins produced during food processing, such as heterocyclic amines, polycyclic aromatic hydrocarbons, and acrylamide found in grilled foods, have carcinogenic properties. Frequent consumption of oily foods during childhood increases the risk of cancer in adulthood. The latest research in the United States shows that a high-fat diet in adolescent girls may elevate the risk of breast cancer and accelerate its development. High-fat diets can induce inflammatory responses, promoting the proliferation of cancer cells.

(4) Disrupting the balance of gut microbiota. Scientists have recently discovered that feeding mice with a high-fat diet alters the composition of gut microbiota, increasing the population of certain pathogenic bacteria while reducing beneficial probiotics. This imbalance interferes with the gut-brain signaling that controls feelings of satiety, leading to overeating and affecting the health of the digestive system.

(5) Damaging the liver. Recent reports have shown that frequent consumption of fried foods can cause symptoms resembling hepatitis, leading to noticeable changes in the liver within a month, resulting in elevated levels of liver enzymes. The reason behind this lies in the fact that fried foods destroy essential fatty acids, as well as the protective nutrients vitamin A and E in the liver, producing highly reactive free radicals that damage liver cells.

(6) Impacting intellectual development in children. Researchers in the UK conducted a long-term follow-up of 14,000 children and found that those who frequently consumed junk food before the age of three might experience lower intelligence later in life. They attribute this to processed diets lacking essential vitamins and other elements crucial for early brain development. During the initial three years of life, the brain undergoes rapid development, and adequate nutrition during this period promotes optimal brain growth. By the age of three, brain development slows down, and the impact of diet becomes less significant. A new study published in the "Journal of Clinical Pediatrics" in the United States reported that children who regularly consume fast food from brands like McDonald's, KFC, and Pizza Hut tend to have lower academic performance than their peers. The research collected data from 8,544 American students, recording their fast food intake at the age of 10 and then comparing it with their reading, math, and overall academic scores at the age of 13. The results showed that children who never consumed fast food scored higher on average compared to those who ate it daily. The theory explaining this phenomenon is that processed diets lack vital vitamins and other elements necessary for brain development, leading to a slowdown in brain development. Additionally, trans fats found in processed foods can severely impair memory. Furthermore, the latest American research discovered that excessive oil consumption can harm the brain, damaging synaptic brain cells and affecting cognitive functions.

(7) Fatigue and lethargy. Consuming high-sugar foods leads to rapid spikes in blood glucose levels, triggering the release of large amounts of insulin and causing the rapid consumption of glucose. Subsequently, blood glucose levels plummet dramatically, leading to feelings of fatigue and irritability. The latest research indicates that unhealthy ingredients and low nutritional content in food can also make people more lethargic and less inclined to be physically active.

(8) Lack of concentration. Through experiments on mice, Cambridge University researchers found that a high-fat diet for nine days led to more errors when the mice navigated a maze. This suggests that junk food may disrupt attention and hinder one's ability to focus on tasks.

(9) Negative impact on appearance. A new study published in the journal "Immunity" suggests that high-fat foods can have adverse effects on one's appearance. Mice fed a high-fat diet exhibited changes in skin proteins and internal inflammation, leading to swelling. This may explain why after a night of revelry, one wakes up with facial puffiness.

(10) Addiction. Research shows that high-sugar foods stimulate the release of dopamine, a neurotransmitter in the brain associated with pleasure and satisfaction, leading to addictive behavior and cravings for more.
