At least with McDonalds, you know what goes into it. They actually have a nutrition label. Show me the nutrition label of the Italian bistro. If you asked, you'd probably get kicked out because you insulted the chef.

So, actually, I'll be way more confident about my health (that's what it's called, not safety, food safety is about you not getting poisoned) eating at McDonalds, than at some rando uptown joint.

Do you really know though? McDonalds has lied in the past quite a bit. For example, they touted their hamburger meat as 100% beef with no additives for quite awhile, then had to fess up when the truth about Pink Slime came out.

Then when they tried to climb on the vegan/vegetarian bandwagon, they had to quickly admit that their fry shortening had beef flavoring added to it, then switch to an entirely different shortening.

McDonalds is a franchise. And like every franchise there is always a lot of leeway depending on the managers and staff.

If you walk five miles a day and do cardio, I wonder if your body would notice.
