    Most drinks stating that they are fruit­flavored (水果味道的) contain no fruit at all, while most of the rest contain only a small quantity of fruit, according to a study carried by the British Food Commission.

    “Shoppers need to check the labels (标签) before buying drinks, though sometimes the actual content can be non­existent，” said Food Commission spokesperson Ian Tokelove. “Food production is highly competitive. ____ It will increase profits, and consumers won't always realize they are being tricked.”

    Flavorings are focused on the flavors of natural food products such as fruits, meats and vegetables, or creating flavor for food products that do not have the desired flavors. Researchers analyzed the contents of 28 strawberry­flavored products sold in stores. ____ Of the 11 products that did contain strawberries, five of them contained less than one percent real fruit. In addition, each juice box contained nearly eight teaspoons of sugar.

    ____ Let's take jam as an example. Some strawberry­flavored jam was labeled as containing no artificial colors, flavors, or sweeteners, but it contained absolutely no strawberries at all.

    ____ Consumers have the rights to know clearly about what they have bought. Under current UK law, food packages do not have to distinguish between natural and artificial flavoring. “Describing a product as strawberry flavor and covering the surface of the packet with pictures of strawberries is misleading. ____ Unfortunately, it is also legal and widespread,” Tokelove said. “It's time to take measures to protect the consumers' rights.”

A. The products which contain real fruit are popular with people.
