Many people have different relationships with dairy products like milk, cheese, and yogurt. Every morning, Mr. Green drinks a glass of warm milk with his breakfast. He likes dairy because it gives him energy for his long workday. However, his wife Anna cannot drink regular cow's milk at all. Her stomach hurts when she eats dairy because she is lactose intolerant. Instead, she buys expensive almond milk or soy milk at the supermarket. Their teenage son, Ben, loves eating yellow cheese and sweet strawberry yogurt. But Ben has bad acne, and his doctor says dairy can make his skin worse. Because of this, Ben tries to eat less cheese every week. For this family, dairy is not a simple food choice for everyone. They must buy different things to keep everyone healthy and comfortable.
