Parents have a tough time dealing with picky eating kids, especially when it comes to healthy foods like spinach, beets, carrots, cauliflower to name a few.

As per the Food Allergy Research, about 1 out of every 13 children is allergic to at least one kind of food and about 40% of those children have experienced serious, life-threatening responses.

About 90% of food allergies in children are caused by 6 common foods such as milk, eggs, peanuts, tree nuts, soy and wheat. Allergies to fruits and vegetables are usually less common. When a child has a food allergy, the immune system overreacts, making antibodies to act against the food, as it were a harmful virus or foreign invader.
