A recent study will be published in April's edition of Alcoholism: Clinical and Experimental Research that looked at sodas in alcoholic beverages. Researchers wanted to know if people who chose less sugary, or sugar substitute sodas had any effect on drinking and "drunkness" than regular soda drinkers.
As it turned out, it sort of did. Diet soda drinkers had higher levels of BrAC, or breath alcohol content, than those who drank regular soda. (BrAC measures alcohol with a breathalyzer and is different than BAC, Blood Alcohol Content). According to the BrAC measures, people seemed to have a higher BrAC reading when they were drinking diet drinks versus non-diet drinks. However, the people in the study did not report feeling any differently or acting any differently. So what does that mean?
Whatever someone chooses to drink, whether it's beer, liquor and soda, liquor and diet soda, or whatever-- what really counts is how much someone is drinking in how long a period of time. Meaning, if someone is drinking 4 diet mixed drinks in an hour or 4 regular mixed drinks in an hour, that person is likely going to feel the effects of the alcohol either way (for better or worse).
