What kind of healthy item are you looking for op? They have plenty of healthy things and plenty of junky as well.
On the top of my head I would think: fresh produce - fruits and veggies. I rarely by from there because in my experience, they go bad fast. Unless I am planing on using it pretty quickly (as in a day or two) I avoid. However, something are ok… grape tomatoes, bananas, baby carrots.
Do you consider cheese healthy? I do (some at least). I love the mozzarella balls in olive oil/condiments. I mix it with the grape tomatoes and my daughter and I have a blast
Nuts - all kinds for all tastes
Granolas (to eat with their greek yogurt)
Plain yogurt (or not)
All kinds of oats for you to cook from scratch or the frozen ones that only requires 3 min in the microwave
All sorts of grains.
Just go and take your sweet time browsing the aisles

That is half the fun!
