Is it okay for my child to have white bread? He seems to like it more than whole wheat/brown bread

To compare the two, whole grains are foods that contain every part of the grain, including the outer layers, bran and germ while white grains are processed and have the bran removed which is where many of the nutrients are stored. Thus white bread end up having less nutritional value compared to whole grain bread. For children, you can offer a variety of breads and cereals each day but of course, best is to choose predominately wholegrain products. I reckon you can buy fortified white bread in which the lost nutrients have been replaced by the manufacturer since your child likes it so much. Gardenia Enriched White Bread is one of these types of breads - it is enriched with vitamins and minerals, fortified with calcium and iron to provide the extra goodness and nourishment that your child needs. That being said, wholegrain foods are still the best option.
