I studied nutrition in a formal setting for four years, so I could detail some complaints, but I’d like to head yours first.
Similarly honey is, I gather from various media, not usually just honey but has quite a lot of sugar syrup added.
So, just saying "peanut butter and honey" you'll get quite different supermarket products on different geographies (I'm in the UK, fwiw).
i once looked at the almond butter label that I buy and it has a TON of calories!
Peanut butter, if it’s made with just peanuts is fine, assuming that the person can tolerate legumes well. There are better actual nut butters though with better omega 3 to 6 ratios.
Honey is just sugar. The supposed pollen allergy prevention benefits people tout is questionable at best.
Banana is just some potassium with a tiny bit of fiber and lots of sugar. One can get their fiber and potassium from greens or tart fruits easily.
Refined carbs is just not good for you.
Again, I have no problem eating it. I just wouldn’t do it regularly and I wouldn’t personally call it healthy.
