Meat & Cheese
While both meat and cheese have plenty of good things for you, such as iron, calcium, and zinc, when they are combined, the nutrients actually hinder one another from being absorbed into the bloodstream. Specifically, the calcium in cheese acts as a blocker for the iron and zinc. While it’s fine to have meat and cheese together every once in a while, make sure you have plenty of meals that feature meat and veggies or cheese and grains.
