20．We live in a society where many people tend to have"black and white thinking"and extreme thinking．Every day a new headline announces a certain food is bad and ruining our health，while praises another food of its amazing benefits．Each year，new studies in nutrition science come out，many of which are against earlier findings．Additionally，we are sold the lie that if we eat the"correct foods"and follow a set of rules，we will gain health and happiness．
We've all heard someone saying，"I ate a brownie（巧克力蛋糕）and I was so bad today．"Someone feels that what they eat determines whether they are a"good"or"bad"person．For instance，someone might also say，"I am a good parent if I feed my child this．"However，food isn't good or bad．What you choose to eat does not determine your value or worth as a human being．The only reason to feel guilty for eating a brownie is that you stole it from the store．
Besides，the idea that you shouldn't eat later in the evening is a nutrition myth．Our metabolism（代謝）keeps running 24hours a day．Rules （like telling yourself when to stop eating） create fear and a sense that you cannot trust with food．Consistently fueling your body every few hours especially when you are hungry will allow you to feel your best．So when you feel hungry before heading to bed，eat some cheese and crackers．
In my opinion，mental health is an important part of one's overall health．I think we can all agree that being terrified to eat some food is not mentally healthy．Rather than focusing on food rules，aim for balance，variety and flexibility．
