Some scientists compare hunger and cravings this way.Hunger is a fairly simple connection between the stomach and the brain.They even simply call it “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 (激活) brain areas related to emotion,memory and reward.These are the same areas of the brain activated during drug-craving studies.So,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 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. 【语篇导读】 本文是说明文。文章主要介绍了关于饮食冲动的一些调查结果,调查表明食物与情感有关系,节食可能会导致食欲的增加。 (　　)1.What is the function of the first paragraph?
