Study shows sodas reduce consumers' fertility

One soda a day is enough to reduce fertility in both women and men. Explanations.

Obesity, dental problems, heart trouble, the harmful effects of sugary drinks on our body are many and widely known. The International Chair on Cardiometabolic Risk has conducted a study on the consumption of this type of beverage throughout the world. In 2015, in France, we bought an average of 50.9 liters of soft drinks (soft drinks, juice with added sugar, energy drinks, sports drinks).

We are still far from the United States with 125.9 liters per year and per capita, or Mexico with 146.5 liters. But this increase in consumption presents an unknown risk: that of reducing the fertility of consumers. This is the result of a Boston University School of Medicine study published on Science Daily. A single soda a day lowers fertility in women or men.

20% decline in fertility

US researchers used data from more than 3,800 women to conduct a questionnaire on their consumption of soda, and another for their male partners. The consumption of sugary drinks reduces the fertility of 20%, male and female combined. Fecundability is the average time needed to conceive a child. For women who consume on average a soda per day, this drop is 25%, for men, it is 33%.

In North America, 15% of couples are affected by fertility problems. "Given the high number of sugary drinks consumed by couples of childbearing age in North America, these results could have significant public health consequences," the authors of the study said. In France, Inserm estimates that 10% of couples have fertility problems.
