McDonalds has healthy food options. Getting a quarter pounder, a salad, and a cup of water is reasonably healthy.
It's the soda and the shakes and the fries that'll getcha.
The quarter pounder is loaded with sugar too unfortunately. The sweet bread is one of the worst things about it. The salad dressing will be too. It's not healthy and doesn't even taste good. But it's addictive.
None of what you described is either healthy or tasty. McDonald food is hyper-processed. They add a lot of sugar to a lot of ingredients.
I used to enjoy the salads at McDonald’s, but it’s been a few years since I’ve seen them on the menu.
