My sister is following lactose free diet lately and she seems to find it good for her health and body as well. She has advised me to go for this diet plan as well nonetheless, I am more keen on knowing about lactose free foods instead of the diet plan. I want to know more about lactose and of course lactose free foods. Moreover, I would like to know about its health benefits, along with some information on what all precautions are required to take before starting with lactose free foods. Please advice.
