We choose food to eat every day．We might know some of the reasons for the choices，but food scientist Dr．

    Brian Wansink has found that we are unaware of 90% of our food decision．Here are some"big ideas"in his research on the hidden power that drives our eating．

    Food for thought

    In one of the studies，Dr．Wansink made volunteers eat chocolate yogurt in a dark room．He told them the yogurt was with a taste of strawberry even though they were all eating chocolate．Finally，65% of volunteers described the yogurt as having a"nice strawberry flavor!"

    The research shows that our imagination has an effect on our taste．If you expect a food to taste good，it will．So take a moment before you eat your unpleasant healthy food to remind yourself that you are eating delicious fish and chips．

    Our eyes eat first

    How your food looks is just as important as how it tastes．Dr．Wansink gave cakes to three groups of people．The cakes were exactly the same but served in different ways．

①Group one got the cake on a nice plate．

    ②Group two got the cake on a paper plate．

    ③Group three got the cake on a piece of paper．

    Dr．Wansink then asked the people how much they would pay for each cake．

    Dr．Wansink then asked the people how much they would pay for each cake．

    ①Group one who got the cake on a nice plate would pay $1.27．

    ②Group two who got the cake on a paper plate would pay 76 cents．

    ③Group three who got the cake on a piece of paper would pay 53 cents．

    Take some time to make your healthy food look amazing．Cut your fruit into a flower shape and put your colourful vegetables on nice plates．This works really well for your appetite （胃口）．

    Out of sight，out of stomach

    Dr．Wansink also found that when people sat at the desk full of snacks，they ate 71% more of snacks a day than those sitting near a clear table．We eat what we see．As a result，put all the unhealthy food in your fridge．

    Hide it and make it really hard to get to．The closer bad food is，the more you eat it．
