New Delhi: As per a new study, scientists claim that tasty food may not lead to weight gain. This study contradicts the perception that tasty foods such as potato chips, chocolate chip cookies is unhealthy and can lead to obesity.
"Most people think that good-tasting food causes obesity, but that is not the case. Good taste determines what we choose to eat, but not how much we eat over the long-term," said Michael Tordoff from Monell Chemical Senses Centre in the US.
Researchers designed a series of experiments to assess the role of taste in driving overeating and weight gain.
They first established that laboratory mice strongly like food with added nonnutritive sweet or oily tastes.
To do this they gave mice two cups of food. One group of mice had a choice between a cup of plain rodent chow and a cup of chow mixed with the noncaloric sweetener sucralose.
The other group received a choice between a cup of plain rodent chow and a cup of chow mixed with mineral oil, which also has no calories.
The mice ignored the plain chow and ate almost all of their food from the cups containing the sweetened or oily chow, establishing that these non-caloric tastes were indeed very appealing.
Next, new groups of mice received one of the three diets for six weeks: one group was fed plain chow, one group was fed chow with added sucralose, and one group was fed chow with added mineral oil.
At the end of this period, the groups fed the sweet or oily chow were no heavier or fatter than were the animals fed the plain chow.
Additional tests revealed that even after six weeks, the animals still highly preferred the taste-enhanced diets, demonstrating the persistent strong appeal of both sweet and oily tastes.
