A quick trip down the frozen-food aisle at the supermarket can be anxiety-ridden. Given the sheer range of options for everything from popcorn to cereal to tomato soup, it’s tough to know what to buy (if you’re not going based on cost alone). Now, a new study suggests having so much variety may be wreaking havoc on our waistlines.
The new study, published in the journal PLOS ONE, shows having so many different brands of the same food may be making us overeat. The researchers asked people nearly 200 people about their consumption of pepperoni pizza. In the study, there were over 70 different pepperoni pizza brands consumed, and the calorie content varied by well over 300%. The researchers then compared the eating habits of people who regularly ate multiple varieties of pizza to people who only regularly consumed the same brand.
