The "health halo effect" happens when food products appear much healthier than they really are because of how they're marketed. Some examples of health halo marketing terms are high protein, low fat, low calories, and fruit sugar. If customers see these words on a bag of chips, it would be reasonable to think that these chips must be healthier than those in other bags. However, when we dig deeper and look at the back label, there is no proof to support this. It's just a technique that tricks people into buying higher-priced items while thinking they are making the healthiest choice available. Another way the health halo effect works is at fast-food restaurants. Most people think Subway is healthier than McDonald's because of its label "Eat Fresh." The sad fact is that it really isn't. People who go to Subway will order more side dishes, which increases the total calories. In a recent study carried out by professors Pierre Chandon and Brian Wansink, they gave 23 students tickets for a 12-inch Subway Italian BMT sandwich, which contains 900 calories, and another 23 students tickets for a McDonald's Big Mac, which has 600 calories. It turned out that the students who ate at Subway were more likely to order extra sides such as soda and cookies, which added another 111 calories to the meal. They were fooled by the health halo effect, thinking that they had a wholesome meal. Before we buy our next "healthy" meal, make sure to read the back label, and be careful not to be tricked by those healthy slogans. Eat healthily and choose smartly!
