The thing is they don't want you tasting the beef. Fast food burgers always come stock with sour pickles, onions, sweet ketchup, mustard or mayonnaise, and a sweet bun. It's a wonder you can taste anything about the beef. The cheese they use is also somehow as sweet as it is salty. I think the beef is the least adulterated ingredient, and it's the one they can't fuck with too much. If there weren't regulations they'd do all sorts of shit in that department, and in nations other than the US they might.
People are addicted to the magic salt/sugar/fat ratio applied to fast food to make it addictive. They know that between the salted fries that they know is going into their proprietary ketchup, and the multi ingredient sandwich you ordered, and the soda and dessert you might get, and nuggets, with dips, they got you "high". And you'll return for that dopamine rush again. As long as the food is somewhat warm, it will deliver that bang.
The burger patty itself is not what they find addictive, it's the whole combination of things as well as the convenience and speed of it.
For this they will pay the cost financially and physically.
