Sure it is.
McDonalds for example uses wheat for it's buns (and even a bit of sesame seed!), beef, tomatoes, lettuce, pickled cucumber, and American cheese (a dairy product). Their fries are made from Russet potatoes (most of which is grown in Idaho, Oregon and Washington). Their orange juice is from fresh oranges raised in Florida and other like places. Their fish for their fish sandwich is whitefish, breaded with cornmeal. Their eggs for their breakfasts come from the same place and the same kind of chickens you get your eggs from. Their pancakes are made from wheat.
What is unhealthy about it?
McDonald's actually has what amounts to Mil-Spec standards for their products.

Back in the 80's when McDonald's opened its first restaurant in Moscow, the company couldn't find in-country suppliers for any of the products they needed. They had to build bakeries, train farmers, set up meat packing plants, etc., so their standards could be met. The workers had to go to months of training to learn how to properly greet and handle customers, work the kitchen, etc., because the Russian work ethic wasn't fitting their corporate policies.
That is, they kept their standards and raised the quality and expectations of their workers and suppliers, not let them slide.
So, whatever you think of Micky D's products, they do have standards and they are actually quite high.
