Daily intake of sugar-sweetened beverages decreases chances of getting pregnant

The amount of added sugar in the global diet has increased dramatically over the last 50 years. Much of that increase comes from higher intake of sugar-sweetened beverages, which constitute approximately one-third of the total added sugar consumption.

While consumption of these beverages has been linked to weight gain, type 2 diabetes, early menstruation, and poor semen quality, few studies have directly investigated the relationship between sugary drinks and fertility.

Now, a new study led by Boston University School of Public Health (BUSPH), United States (U.S.), researchers has found that the intake of one or more sugar-sweetened beverages per day — by either partner — is associated with a decreased chance of getting pregnant.

The study was published in Epidemiology.

“We found positive associations between intake of sugar-sweetened beverages and lower fertility, which were consistent after controlling for many other factors, including obesity, caffeine intake, alcohol, smoking, and overall diet quality,” says lead author Elizabeth Hatch, professor of epidemiology. “Couples planning a pregnancy might consider limiting their consumption of these beverages, especially because they are also related to other adverse health effects.”
