2．Scientists have long debated （辯論） the best diet for health.But now some experts believe that it's not just what we eat that's important for good health，but when we eat it.When our diet habit matches the biological clock well，our body can work at its best.Breaking the rule—by eating late meals or having midnight snacks，for example—could lead to weight gain and metabolic （新陳代謝的） trouble.
   Many people，however，eat from the time when they wake up until shortly before they go to bed.Studies show that the average person starts with something like milk and coffee shortly after rising and ends with a glass of wine，a late-night meal or a handful of chips，nuts or some other snacks shortly before bed.That habit of eating is against our biological rule.
   Scientists have long known that the human body has a master clock in the brain，which controls our sleep-wake cycles in response to bright light exposure （暴露）.A couple of decades ago，researchers discovered that there is not just one clock in the body but a collection of them.Every organ has a clock that controls its daily cycle of activities.Studies show that in every organ，thousands of genes （基因） are turned on and turned off at almost the same time every day.
   We've lived on this planet for thousands of years，and while many things have changed，there has always been one constant：Every single day the sun rises and at night it falls.We're designed to have 24-hour systems in our body.They exist because，just like our brains need to go to sleep each night to repair and reset themselves，every organ needs to have time to repair and reset itself as well.
