Cranberry and Blueberry Here Again–Representing Single Foods

Last week, two news stories raised up as headlines: 1. New meta analysis shows cranberry product is effective to prevent urinary tract infection, reassuring what our grandma kept telling us; 2. wild, but not normal, blueberry is considered to protect DNA damages.


These stories required a lot of efforts from a lot of professional researchers–their findings are precious, giving people new clues for things to look for to eat. But, such kind of finding is so familiar, or even feeling mossy today. On one day, guys walking down the street may bring up some foods they learn should be eaten from the newspaper, but to the next couple days, old foods are washed off as new findings come out. It could be overwhelming to see new super foods day-to-day. But one single food can provide the whole nutrients for sure, nor it can be so magical to really treat some diseases or conditions. In other word, people just can’t eat based on these “single food findings;” what every person truly need is a steady but science-proven balance diet.

Well, though I am not a fan of super food, but from my understanding, research in single super food is still meaning ful. They can be used specially in some situations: for example, if a person is under high working pressure, his body will produce more free radicals, which require more antioxidant to neutralize them–then, perheps blueberry in greater amount may help a little.

As a person studying nutrition, friends always like to ask questions such as “What food I can eat to make me healthy? Tell me some foods!” “Do you eat a lot of brocolli? I heard they are very good.” “What? You eat McDonalds? You are nutrition person!”–and I believe all people in nutrition world can’t escape. What people always thinking is eating a food and turn to be healthy on the other day; however, only a balanced diet can boost your health most effectively. A balanced diet is meant to provide right amount of energy, along with sufficient vitamins, mineral, compounds from animals and vegetable–which can only be obtained from a wide range of foods.
