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. Here is another situation. Perhaps you are not feeling well. The only thing you want to eat is a big bowl of chicken soup, like your mum used to make when you were sick as a child. Food cravings are a strong desire for a specific type of food. And they are normal.
Scientists at the website How Stuff Works compare hunger and cravings this way. Hunger is a fairly simple connection between the stomach and the brain. They even call it simply “stomach hunger”. When our stomachs burn up all of the food we have eaten, a hormone (激素) sends a message to one part of the brain for more food, which regulates our most basic body functions such as thirst, hunger and sleep. The brain then produces a chemical to start the appetite and you eat. Hunger is a function of survival.
A craving is more complex. It activates brain areas related to emotion, memory and reward. These are the same areas of the brain activated during drug-craving studies. Because of this, some scientists call food cravings “mind hunger”. People often crave foods that are high in fat and sugar. Foods that are high in fat or high in sugar produce chemicals in the brain. These chemicals give us feelings of pleasure.
In a 2007 study, researchers at Cambridge University found that dieting or restricted eating generally increases the possibility of food cravings. So, the more you deny yourself a food that you want, the more you may crave it. However, fasting (禁食) is a bit different. They found that eating no food at all for a short period of time lessened food cravings.
So, the next time you crave something very specific, know that your brain may be more to blame than your stomach.

One day, Lindsay and Erica were sitting at Lindsay’s house working very hard. Fourth grade was tough, and they were working on a science project about weather.
