Child's Dinner: Scientific Foundations of Evening Nutrition Physiological Characteristics of Evening Metabolism Dinner for a child aged 7–11 years represents a complex dietary challenge, requiring a balance between satiety, lightness, and preparation for sleep. Unlike adults, children in the early school age group have a higher basal metabolic rate by 25–30%, and anabolic processes (synthesis of new tissues) are particularly active during the night. The last meal should provide material for growth, but at the same time, not overload the digestive system, which transitions to a "maintenance" mode at night. Interesting fact from endocrinology: the secretion of growth hormone (somatotropin), critically important for bone and muscle growth, reaches its peak during the first phase of nighttime sleep. However, its secretion can be suppressed if the dinner was too calorie-dense or contained a large amount of simple carbohydrates that cause a sharp insulin spike. Thus, a well-composed dinner indirectly promotes optimal physical development in children. Nutrition Chronobiology: Why Time Matters According to research in the field of chronobiology (the science of biological rhythms), digestive enzymes such as pepsin and amylase reduce their activity after 18–19 hours. In children, this shift may occur a bit later, but the principle remains: a late and heavy dinner leads to incomplete digestion, fermentation of food in the intestines, and restless sleep. The golden rule: the interval between dinner and bedtime should be at least 1.5–2 hours. This time is necessary for the completion of the gastric phase of digestion and the beginning of the evacuation of contents into the duodenum. A child going to bed with a full stomach is more likely to experience superficial sleep, sweating, and tossing and turning, as the body has to spend energy on digestion instead of full recovery.
