Diet sodas and artificial sweeteners may not be the healthy alternatives to their regular counterparts that many people believe them to be. Two new studies out of the University of Texas Health Science Center in San Antonio suggest quite the contrary: artificial sweeteners may promote increased waistlines and insulin resistance.
One study focused on a population of elderly people, while a related study focused on the long-term impact of aspartame in mice.
The team first assessed data from 474 elderly Mexican Americans and European Americans. Diet soft drink users, as a group, experienced 70 per cent greater increases in waist circumference compared with non-users. Frequent users, who said they consumed two or more diet sodas a day, experienced waist circumference increases that were 500 per cent greater than those of non-users.
