My autistic son cholesterol is 198, and is very over weight. the school uses food as a reward, and need a low fat low cholesterol sweet for them.

The best reward: for him is not food. Kids with autism can be satisfied with rewards other than food like music or an activity. It really depends on the kid. I know food is the easiest reward but if he is already very overweight, you are not doing his overall health any favors. Sorry, I know this is not what you want to hear but I sincerely want your son to have the best possible health and behavior.

Oatmeal & coconut: Oatmeal is a great food to help naturally lower cholesterol. There are lots of great low calorie cookie recipes available online. Here's a link to one of them: http://recipes.sparkpeople.com/recipe-detail.asp?recipe=325473 Good luck!
