According to a recent study published in Journal of Consumer Research, many people believe that healthy food must be more expensive than unhealthy food. In fact, the study\'s researchers found that a high price tag will even convince consumers that a certain food is healthful.
According to Rebecca Reczek, co-author of the study, the purpose of the study was to examine a_popular_belief. Sometimes the belief can be true: Organic produce and wild-caught seafood typically cost more money. But other times, the nutritional value of food ranks all the same.
In one experiment, Reczek\'s team gave a group of participants a new food product called “granola bites”. Some participants were told the product was very healthy. Other participants were told the bites had little nutritional value. Participants who were told the granola bites were good for them rated the snack as more expensive than the participants who thought the bites were unhealthy.
In another experiment, participants were given a health food bar labeled as “the healthiest protein bar on the planet”. Some participants were told the bar cost just $0.99, others were told the bar was $4. And here\'s what happened: The people who were given the “cheaper” bar needed to read a lot more reviews about the product when it was priced at a lower price point in order to trust that it was healthy.
The idea that we all believe healthy food needs to be more expensive works against us. All food companies need to do is push up the price to convince us.
But Reczek said, “When we shop, we don\'t have to be led astray. We can compare nutrition labels and we can do research before we go to the grocery store. We can use facts rather than our intuition (直觉)”．
