Kraft Singles are a factory-made abomination of melted cheese powder and seed oil, masquerading as a convenient snack. You're not eating cheese, you're eating a chemical cocktail designed to be addictive. Just use real cheese.
Why trash
Legally cannot be called 'cheese' — it's a 'pasteurized prepared cheese product' made with seed oils.
Try instead
Grass-fed cheddar, brie, or gouda cheese.
