From VOA Learning English, this is the Health & Lifestyle report.We have all been there. It’s 3 o’clock and you’ve been hard at work.As you sit at your desk, a strong desire for chocolate overcomes you.You try to busy yourself to make it go away. But it doesn’t.In fact, the more you try to NOT think about a square of deep, dark chocolate melting in your mouth, the more you want it. You can even smell it!Here is another scenario. Perhaps you are not feeling well.You’re coming down with a cold and feel rundown.The only thing you want to eat is a big, bowl of chicken soup, like your mom used to make when you were sick as a child.A food craving is a strong desire for a specific type of food. And they are normal.Most people have them even though what we crave might be different.One person might crave sweet chocolate, while another might crave salty potato chips.Sometimes the foods we crave are not super healthy ones but rather fatty or sugary foods.
