Is subway more bad for you than McDonald's?

No. Subway is far healthier than McDonald's. McDonald's patties have many preservatives that can cause cancer, not to mention the grease and calories. Subway's food compared to McDonald's is healthier by default because they use clean ingredients, fresh dough made there, fresh veggies, and pure meat with no preservatives. Their food isn't fried it's baked which is also another healthy factor.
