Q. Is there a link between soy formula and ADHD? I've heard that alot of kids with ADHD were on soy formula. I've also heard bad things about boys that were on soy formula. Things like they are more likely to be infertile when grown up because of estrogen in the soy. Is any of this true? Is regular soy milk safe for little boys to drink

A. i’m not sure about ADHD and soy…ADHD is a condition with physical impact on the brain and you are born with it. But soy in general is not a really good idea. It’s ironic that health fanatics consider it as a good thing. It should be eaten moderately and not extensively.

Q. My toddler is refusing to take the formula diet. My toddler is refusing to take the formula diet. Doctor has prescribed him iron drops. But why is the need and could he be iron deficient at this age?

A. His iron supplements would be incomplete and so is the requirement of iron drops being prescribed by the doctor. My daughter was also found to be iron deficient and the doctor suggested me to add diets such as oats, beans like soy beans, cereals, green vegetables like spinach, seafood, egg yolks, iron fortified breads, dry fruits. Iron plays a vital role in the formation of blood and its deficiency can lead to anemia. Early stage child anemia is harmful for the child. Do not forget to give oranges and citric fruits because it helps in the absorption of iron from foods taken.

Q. Is Omega 3 fatty acids helps brain development of babies? There are all sorts of food supplements that add omega 3 to their baby formula. Is it helpful? Can it harm?

A.

I found a nice video with a pediatrician that explain that exactly!!
