Anything in moderation is always safe for consumption. Since alcohol is a big ‘NO’ for moms-to-be and certain drinks should be completely avoided during pregnancy, many pregnant women opt for soft beverages like soda, soft drinks, mocktails, etc. Drinking beverages during pregnancy is safe when consumed in moderate amounts. Though soda is considered a refreshing replacement to alcohol, according to a study, when the sugar intake was more than usual for the mothers-to-be, especially in the form of sodas, the newborn grew up with poor non-verbal and problem-solving skills along with poor memory. The carbon dioxide content in sodas causes belching and flatulence. Also, fructose is a natural sugar — causes gas and bloating.
