It is generally recommended to give walnut oil to your baby when your child is 9-10 months old. Because the intestinal flora of babies before and after the addition of complementary foods is not yet stable, the consumption of walnut oil is likely to lead to diarrhea. Walnut oil can effectively promote intestinal peristalsis and can provide essential trace elements for the body’s metabolism and promote the development of baby’s bones. Walnut oil can be eaten with complementary foods, such as noodles, rice, porridge, etc.; mixed with cold salads, such as cucumbers, apples, bananas, etc., directly pour walnut oil into the dishes and stir to eat. Walnut oil is rich in flavor and nutrition, so it is also added to beverages for consumption, such as directly pouring into milk, yogurt, honey and juice together. In addition, it should be noted that walnut oil should be added according to the baby’s diet, and the right amount is appropriate to avoid excessive diarrhea.
