Many people who are overweight have poor digestion(消化). For the most part, poor digestion is not a habit given by our parents. We give it to ourselves through the way we eat. Eating to get les s stress or anxiety is often the mistake most people will make. Oh, poor digestion can lead to weight problems. Here’s how: When a person feels stressed, the part of the central nervous system that connects digestion switches off. This is called the parasympathetic nervous system(副交感神经系统). At those times of stress, the body can take in food and  process some of it, but digestion doesn’t work correctly to digest all the nutritional(营养的)goodness from the food. Poor digestion is not always obvious by observing symptoms; you can get some illnesses but not always. Poor digestion can be seemingly silent. If you eat when you are stressed, anxious, or nervous, you might as well be eating cardboard for all the nutrients your body gets. Yes, eating when stressed is a gaining situation. Now you might think, well, if I’m not digesting, the calories aren’t getting handles, so I should be losing weight. Good idea, but wrong reality. When digestion is not proper, the body starts “starving” from lack of necessary nutrients(营养物). Yes, it goes into a starvation（饥饿）problem and starts absorbing(吸收) fat and energy. It thinks it’s in a famine(饥荒). The good news is that it’s easy to make some corrections and get rid of stress at mealtimes. If you feel stressed often, it can be helpful to take other food that contains multiple B vitamins. These help, but you could still find yourself stressed at mealtimes. 小题1:The author wrote the passage to tell us        .
