Rice flour is easily digestible, low in allergens, and is suitable for the first infant formula. Rice flours contain high levels of protein and starch, besides being sodium, potassium, magnesium, and B vitamins. They are gluten free, so it’s a great alternative for those who do not tolerate it. Rice flour is one of dozens of flour types made from whole-grinded rice groats. It should be noted that rice flour is highly absorbing liquids, which means that it will be necessary to fill the liquid with a lot more than usual.
