BUFFALO, N.Y. – A recent study conducted by researchers at the University at Buffalo (UB) has stirred up interest by suggesting that incorporating beans in chili during pregnancy may help lower the risk of gestational diabetes. This potential breakthrough was published on March 14 in the journal Nutrients.

With a concerning increase in gestational diabetes rates—from 6% in 2016 to 8.3% in 2021, as reported by the Centers for Disease Control and Prevention—the urgency for effective preventive strategies is mounting. Gestational diabetes occurs during pregnancy and, if left untreated, can pose significant health risks to both the mother and the baby. While it often resolves after childbirth, it can increase a woman’s likelihood of developing Type 2 diabetes later in life. Factors contributing to this condition include pre-pregnancy obesity, excessive weight gain during pregnancy, advanced maternal age, poor diet, lack of physical activity, and recent studies suggest even COVID-19 may be a factor.

The Nutritional Power of Beans

The researchers focused on beans, known for their rich content of protein, complex carbohydrates, and fiber, which are essential for a healthy pregnancy. Previous studies have indicated that diets high in beans could yield healthier blood sugar levels and lower the risk of Type 2 diabetes largely due to their fiber content. Yet, there has been limited research on their impact specifically during pregnancy, particularly within the context of a typical American diet.

“Our research aimed to analyze bean consumption in relation to gestational diabetes, specifically through chili, dried beans, and bean soup,” said Dr. Xiaozhong Wen, the first author and an associate professor of pediatrics at UB. Remarkably, only the consumption of chili was statistically linked to a lowered risk of gestational diabetes, with pregnant women who ate chili once a month showing a 3.5% risk compared to 7.4% for those who abstained from chili.

The Science Behind Chili's Benefits

Though the exact mechanisms remain unclear, researchers speculate that compounds found in chili, such as capsaicin and certain phenolic compounds in beans, could play a crucial role in regulating blood sugar levels. Capsaicin, a component of chili powder, may assist in slowing glucose absorption and enhancing insulin sensitivity, which is vital during pregnancy.

The study evaluated 1,397 pregnant participants using data from the Infant Feeding Practices Study II, a national study initiated by the FDA in collaboration with the CDC. The research needs to be followed up by studies with larger and more diverse populations to validate these findings.

What This Means for Pregnant Women

Given these preliminary results, should expectant mothers consider adding chili to their diets? Dr. Wen suggests that moderate consumption of chili could complement a balanced approach to managing gestational diabetes. This should be done alongside other vital clinical recommendations including regular screenings, exercise, and medications if necessary.

The co-principal investigator, Dr. Todd C. Rideout, along with his team at UB, emphasizes the need for further research to confirm these promising links. They call for detailed assessments of dietary intake and a randomized controlled design for future studies.

In a world where gestational diabetes is on the rise, simple dietary adjustments like incorporating beans in chili could be an effective strategy for pregnant women aiming to safeguard their health and that of their babies.
