Dr. David Katz, director of Yale University's Prevention Research Center said, "In my 20 years of clinical practice, patients who consume diet soda tend to have more of a sweet tooth; to get more sweet cravings; to eat more foods with added sugar; and to like and eat more processed food than patients who avoid both regular and diet soda."
Some critics said not to throw away the diet soda just yet because of the lack of ʺa scientific controlʺ like a family history of cardiovascular disease or hyperlipidemia. Cardiovascular disease and hyperlipidemia are both known risk factors for stroke and heart attack,
Also, the study population may have been at a higher-than-normal risk for cardiovascular events. Roughly three-quarters of the study participants were African-American or Hispanic; both are considered to be at a higher risk for cardiovascular problems.
Finally, Gardener and her colleagues’ research failed to detect an increased cardiovascular risk among daily drinkers of regular soda.
