Cheese can be a healthy addition to your diet--the food is packed with calcium, which can keep your bones and teeth strong. Plus, cheese is a good source of protein and fat, which can help you stay full. Cheese also can help you regulate and maintain the 'good' bacteria in your digestive tract mouth. Actually, one of the healthiest types of cheese you can eat is Swiss cheese. It tastes delicious, but also delivers a healthy dose of calcium and the vitamin B12. Cheddar is slightly less healthy, because it has more calories than Swiss cheese.
I think the best cheeses are natural and not processed. However, in doing research I found an excellent suggestion from livestrong. They said to choose cheeses with strong flavors so you can use less of the cheese. Sounds simple but good.
