At one year old, children’s bodies are not fully developed, so many dietary considerations are needed. Although yogurt has good health benefits as a dairy product, it is a bit too nutritious for children. Therefore, it is best for babies around one year old not to drink yogurt, as it is difficult to digest.

1. At one year old, the gastrointestinal system of the baby is not yet fully developed, the gastric mucosal barrier is not sound, and the activity of gastric acid and pepsin is low, making it difficult to digest and absorb the nutritional components in yogurt. Therefore, it is best not to drink yogurt.

2. Yogurt is made by fermenting milk and contains a large amount of lactic acid bacteria with a low pH value. The gastrointestinal tract of a one-year-old baby is relatively tender, and yogurt entering the gastrointestinal tract can corrode the gastrointestinal mucosa. It is best not to give children yogurt.

3. It is not advisable for children of this age to drink yogurt because the microbial flora in the infant’s gastrointestinal tract is in a stage of growth and change and is not yet stable. Drinking yogurt may cause an excessive intake of Lactobacillus acidophilus, leading to a disruption of the ecological balance of the original microbial flora in the intestines, thus causing intestinal diseases.

4. During the infancy, the gastrointestinal system of children is not yet fully developed, the gastric mucosal barrier is not sound, and the activity of gastric acid and pepsin is low, which is only half of that of adults at 4 to 6 months. The processing of yogurt involves an acidification process, resulting in a lower pH value. After entering the gastrointestinal tract, it can ‘corrode’ the delicate gastrointestinal mucosa of infants, thereby affecting digestion and absorption.
