Lower the Risk of Heartburn
According to Linda Nikolakopoulos, RD, who is based in Boston, caffeine is often a main trigger for heartburn and acid reflux, and her clients have seen tremendous success with alleviating symptoms by going caffeine-free. Previous research has shown that coffee, in particular, can boost heartburn risk but even tea to a lesser extent can be problematic. That’s because coffee has a high degree of acidity, similar to other drinks with high acid content like orange juice.
“This can be a game changer if you suffer from these issues,” she says. “Cutting back or eliminating caffeine is one of the first strategies I recommend, because it can provide great relief.”
When Kenney sees women who have fertility concerns, she usually suggests they dial way back on the caffeine.
“Caffeine can decrease the flow of blood to the uterus, which can interfere with implantation,” she says. “Too much caffeine can also increase the risk of blood clotting and miscarriage.”
When it comes to fertility, cutting caffeine has the potential to benefit men as well. A June 2017 study in Nutrition Journal suggested caffeine may reduce the integrity of sperm by affecting DNA, potentially reducing reproductive function. The study does note that results have been inconsistent, though.
