[snip]: If you took the time to read the McFood Facts, you would see that they serve (Grade A Beef). McDonald's can not afford to provide a poor product.
Grade A "indicates the expected palatability of the meat...meat grading should not be confused with meat inspection." -- Dennis E. Burson, University of Nebraska, Extension Meats Specialist.
In other words, the meat McDonalds buys is expected to taste good; that says nothing about the fat content, cholesterol content, filth content, bacteria content, pesticide residue content, hormone residue content, and other illness-causing factors. Grade A burger patties may taste good (if you like greasy, salty slabs of flesh), but they're not healthy for you.
None.
