I've recently seen some negative commentary linking diet soda consumption by pregnant woman to the risk of premature babies. For anyone concerned about this, it's important to remember that the overwhelming body of scientific research contradicts this claim. Years of studies have proven that diet soda does NOT have any harmful effects on pregnant woman or their babies.
For more information on the topic, check out this "Myth of the Month"from the Calorie Control Council website.
"The use of low-calorie sweeteners in pregnancy has been well studied both in humans and in animals. Before approving the currently available low-calorie sweeteners, the U.S. Food and Drug Administration determined that the low-calorie sweeteners are safe for all populations, including special groups such as the elderly, children, and pregnant and lactating women. Further, leading health groups such as the American Dietetic Association and American Diabetes Association support the safe use of low-calorie sweeteners during pregnancy. Low-calorie sweeteners can help pregnant women enjoy the taste of sweets without excess calories, leaving room for nutritious foods and beverages without excess weight gain. Excess weight gain during pregnancy has been shown to be harmful to both the mother and developing baby."
