Paediatrician Indirapuram. # Are juices and shakes healthy and how much can I give? Pre packaged juices and shakes Are not healthy foods to be offered to children.IIt is always better to give whole fruit rather than fruit juice.Eating fruit has advantages, including more fiber content, more nutrient content and lesser chances of microbial infection, which can happen while extracting juices.. Fruit juices should not be offered to children less than 2 years. For children 2-5 years, upto 125 ml of only fresh home made fruit juices with no added sugars can be given per day. In children older than 5 years the amount can be increased ro 250 ml per day but it should be fresh home made and without added sugars. Canned and packaged fruit juices Are not advisable.
