Many foods contain hydrogenated oils, and occasional consumption in small amounts does not usually pose serious harm to children. However, long-term consumption of large quantities of foods containing hydrogenated oils may increase the risk of obesity, affect growth and development, and increase the risk of cardiovascular disease in adulthood. 1. Increase the risk of obesity: Hydrogenated oils are inexpensive, have a unique flavor, are highly malleable, and are widely used in a variety of processed foods, such as fried foods, cakes, ice cream, etc. Consuming a large amount of these very high-calorie foods may increase the risk of obesity in children. 2. Affect growth and development: hydrogenated oils tend to affect children’s absorption of essential fatty acids, thus affecting growth and development, especially brain development. 3. Increase the risk of cardiovascular and cerebrovascular diseases in adulthood: hydrogenated oils can increase the bad cholesterol in the blood, that is, “low-density lipoprotein”, increasing the risk of cardiovascular and cerebrovascular diseases in adulthood. Parents should try to control children’s consumption of foods containing hydrogenated oils, and if they feel unwell, they are advised to consult a doctor promptly.
