My son only ate white pasta and hamburgers from age 3-12. Then suddenly in high school he started eating everything including sushi, Indian foods, mediterranean dishes, etc. He cannot tell me why but there is hope! Maybe puberty?

My son is 10 and although he is getting better at trying new things, he is still very limited with what he will eat. Limit spices, my son likes just salt. Other spices are too much for him. Try to avoid foods that have a very strong scent. Things like garlic and onions will ruin everything else on the plate because the smell is overpowering to him. Let him touch everything. This took me a while to get over. Being that he is 10 now, he should be using a fork, but he needs to feel textures before eating them. He eats everything with his hands. Get him involved. Since my son was walking, I had him in the kitchen with me. He is older now, so I will let him pick out a recipe, help shop for the items and then help with the cooking. He has been more willing to try new things because he is the one that picked out what we are making. Make it fun. We went to a Thai restaurant and I was wondering what my son would eat there, if anything. We ordered him plain chicken, but when the hot pot came to the table and it was on fire, he was mesmerized and wanted to try it. Hope that helps...

Lol my Bella recently informed me, "I only eat WHITE foods, mom!"
Guess it isn't always texture, lol.

Research shows it takes 12-15 times of introducing a new food before a child can make a proper distinction as to whether or not they like it. Please don't give up on the introductions. It take TONS of patience. Get him involved as much as possible in the process of food choices, preparation, etc. As AutismDad said, take it very slow. The process is allow them to touch it, smell it, touch it to their lips, then to their tongue, then take a bite. This is a slow process and most likely will not happen at the first try but through several attempts. As a nutritionist, I've seen this happen often. Also, try to have them pick out things they will try (various food categories; i.e. grains, veg, fruit, dairy), even if it's a bite until they can get used to seeing it on their plates and used to touching it and so forth.

That is the key. Textures. Find foods with the same textures. Get him to touch them and compare with a textures food he likes. Smell and then taste, but go slow as he will fight at first, you need the patience of a saint. It is a long journey and we are still on it! It will be a battle but I'm the end he will try :) keep your chin up and good luck.
