He has a shop bought biscuit or two (like a fig roll made of figs and pastry) less than once per week. He has a piece or two of chocolate about twice per year, never eats sweets ever, less than once per month eats a few crisps (would be at a birthday party or special picnic outing), at the few birthday parties he has been to he's had jelly, ice cream and cake.
Hmmm...I think that's most of it.
He won't eat mashed potato or rice - these things he is offered and refuses, once in a while he will ask for a taste and still not like it, he has never liked mashed food or rice, ever.
He doesn't like green peppers, butter beans, short stemmed broccoli, cauliflower - these things I can ask him to eat a bite and he will but I don't push it as it is a sincere dislike.
He likes a variety of nuts but I very rarely offer nuts (only 2 or 3 nuts and less than once per month) as it results in diarrhoea, however I do add coconut, ground almonds, flaked almonds and peanut butter in cooking which appears not to have a negative effect. He is fine for example if I make naan with ground almonds and sultanas mixed through or cake or pancakes with ground almonds.
A year ago the range of meat and fish would not have been as extensive but it was something I was constantly aiming to increase. He ate egg every morning for breakfast because that's how I worked out how to get protein into him. From 6 months to 2yo+ I made a lot of bean burgers, fritters, felafel, lentil patties type things (back then he refused anything made of kidney bean, he'd try it and spit out clearly not liking the taste or texture, but many other beans went down well, it was trial and error to discover which were acceptable and which spices he preferred) and experimented every week with fish and fish fingers.
Well, depending on your personal diet and beliefs about food types this may or may not be a list of healthy foods which is what you asked for, but it's what we eat, it's what DS eats.
