Frequent consumption of processed foods may increase the risk of chronic diseases such as obesity, hypertension, diabetes, and cardiovascular disease. The main impacts include nutritional imbalances, excessive intake of additives, harmful effects of high salt and sugar content, and disrupted gut flora.
Ultra-processed foods are industrially produced foods that have been supplemented with at least five ingredients and additives, typically including sugar, stabilizers, preservatives, colorings, and more. These foods are often high in sugar, fat, and calories. Common examples of ultra-processed foods include cola, bread, cakes, potato chips, cookies, candy, hamburgers, instant noodles, and ice cream.
Their addiction is remarkable; the more you eat, the more you crave.
However, hunger is regulated in the brain's hypothalamus by two main hormones: ghrelin and leptin, which have opposing effects. Ghrelin stimulates hunger, while leptin suppresses it.
Ghrelin is the primary hormone that stimulates appetite and is secreted by the stomach when it empties. Acting on neurons in the hypothalamus, it stimulates hunger.
The Dangers of Consuming Processed Foods
- Nutritional Imbalance
Processed foods significantly deplete natural nutrients like vitamins and dietary fiber. Long-term consumption can lead to micronutrient deficiencies. It is recommended to supplement nutrition with fresh fruits, vegetables, and whole grains.
- Excessive Additives
Accumulation of food additives like preservatives and colorings in the body can cause allergies or metabolic burden. Choose foods with simple ingredient lists and limit consumption.
- High Salt and High Sugar
Excessive sodium and added sugar in processed foods can increase blood pressure and blood sugar levels and are associated with the development of essential hypertension and type 2 diabetes. Daily intake should be limited.
- Intestinal Disorders
The low fiber content of processed foods can disrupt the balance of intestinal flora and may induce irritable bowel syndrome, which can be improved with fermented foods and probiotics.
A daily diet should focus on fresh ingredients and limit processed food intake. Monitor blood pressure and blood lipid levels regularly. Seek medical attention promptly if persistent indigestion or metabolic abnormalities occur.
