    If our bodies actually suffer from eating too much sugar, then why do we like it? And why don 't we have such a strong eager for food like, say, broccoli (西兰花)，which is a great source of Vitamin C,Vitamin K iron, all things our body actually needs? If it's so bad for us, then why does sugar taste so good? There are hundreds of journal articles trying to answer that very question. Let' s take a look at what they' ve come up with.

Studies have shown that the love children have for sugar may be born with. In other words, kids may have a built-in love of all things sweet. The preference for sweet foods is found to be already evident in newborns, who prefer sweeter formulas (配方). It also seems to be shared by children globally across cultures and climates. There’s further evidence that kids’ taste buds (味蕾) are more sensitive to bitter-tasting foods, further pushing them to reach for the sweets. One study showed that adults tend to maximize their sugar preference at about the level of sugar in a can of soda, but older children still liked drinks that were twice as sweet. The scientists couldn't find a limit to the concentration of sugar younger children preferred. It turms out that the kids still liked the sugary drink even past the point where there was too much sugar to be dissolved (溶解) in water anymore.

Sugar gets a bad fame, but it isn't all bad. Sugar provides our bodies with calories, which we can then change into energy. Children, in particular, need this energy to fuel their rapid growth. Sugar also helps us store fat, which can be drawn on later if needed. Our body knows to pursue the things it needs as two way of signaling our brain to start eating what we’re missing.

As a vegetarian (素食主义者)，I know that when I start thinking about stealing the peanut butter sandwich that's been floating around in my kid' s backpack, it' s probably not because the sandwich is so delicious. It' s more likely that I haven't gotten enough protein for the day.
