Drinking coffee in moderation generally does not affect height growth. Long-term consumption of large quantities of coffee may affect the absorption of calcium, thus somehow affecting height growth. Every 100g of coffee beans contains 17.1g of protein, 8.8g of fat, 68.9g of carbohydrates, and varying amounts of vitamins and minerals. Normal drinking coffee does not affect the body to grow taller, but a large amount of coffee intake, in which too much caffeine intake will increase the urinary calcium discharge, but also can mildly weaken the intestinal calcium absorption, resulting in calcium loss, which affects the growth of height to some extent. Therefore, adolescents are not recommended to drink a lot of coffee. Before going to bed, you should avoid consuming too much black coffee, so as not to cause excessive nerve excitement, thus affecting the quality of sleep. The growth of the organism is related to a variety of factors, and there is still a chance of growing taller when the epiphysis has not yet closed completely. You can eat more food rich in protein and calcium components, such as eggs, beef, milk, shrimp, carrots and so on. People with height abnormalities also need to seek medical attention to rule out height growth restriction caused by diseases and other factors, such as insufficient secretion of growth hormone.
