There's no saying which is better. According to the nutrient content of pure milk is relatively higher than yogurt, because yogurt is fermented by lactobacilli, lactobacilli will consume part of the protein and fat. However, according to absorption, the nutrients in yogurt are more easily absorbed and utilized by the body. For example, calcium in milk, pure milk in the calcium content is very high, but calcium in the human body is very stable, it is easy to be affected by diet or other factors and the formation of insoluble calcium, so the body is difficult to absorb. Although the calcium content of yogurt is lower than that of plain milk, the calcium of yogurt has been converted into calcium lactate that is easily absorbed by the human body and is more easily utilized by the human body. If you want to grow taller drink yogurt is better.
