Foods High in Added Sugars May Raise Your Risk for Kidney Stones, New Study Finds

Consuming too many foods with added sugars may increase your risk of developing a condition that many describe as being as painful as childbirth: kidney stones. It is estimated that up to 15% of the global population is affected by kidney stones, which can cause severe pain, nausea, vomiting, fever, and bloody urine. Kidney stones can also lead to infections and kidney disease.

Now, researchers suggest that high consumption of added sugars should be included as a potential risk factor for kidney stones. They reviewed data from over 28,000 adults who reported their dietary habits during in-person and telephone interviews. After calculating the participants' intake of added sugars, the results showed that those in the top 25% of added sugar consumption had significantly higher odds of developing kidney stones. Specifically, individuals who consumed more than 25% of their total daily calories from added sugars faced an 88% increased risk compared to those who consumed minimal added sugars.

The lead author of the study noted that these findings suggest limiting added sugar intake may help prevent the formation of kidney stones. However, further research is needed to better understand the association, such as identifying which types of kidney stones are most linked to added sugar consumption and determining the ideal level of sugar reduction to lower the risk.

Despite the need for more studies, the researchers say this study provides valuable insights for both patients and healthcare providers looking to reduce the risk of kidney stone formation.
