Consuming a high-fructose diet regimen throughout pregnancy might create defects in the placenta and restrict fetal growth, potentially increasing a baby’s risk for metabolic healthiness issues later in life, according to research in mice and people by a group at Washington University School of Medicine in St. Louis.
However, giving the mice allopurinol, a generic drug often prescribed to handle gout and kidney stones, appears to mitigate the negative maternal and fetal effects. The findings suggest it could be feasible to devise a prenatal screening test and treatment strategy for pregnant women along with higher fructose levels.

Fructose, a sugar occurring naturally in fruits and honey, has actually been popular for decades among meals manufacturers that procedure it in to high-fructose corn syrup used to sweeten meals and beverages. In fact, researchers have actually reported that the refined sugar accounts for a lot more compared to half of every one of sweeteners used in the U.S. food-supply chain. And in recent years, there’s growing concern that fructose in processed meals and sugary drinks could be linked to diabetes and obesity.
“Because the early 1970s, we’ve been consuming a lot more fructose compared to we should,” said Kelle H. Moley, MD, the School of Medicine’s James P. Crane Professor of Obstetrics and Gynecology and the study’s senior author. “It is becoming increasingly crucial to know Exactly how fructose consumption is impacting human health. This study shows potentially negative effects of a high-fructose diet regimen throughout pregnancy.”
Fructose is processed differently compared to others sugars such as glucose, which the physique converts in to energy. Instead, fructose is broken down by liver cells that turn the sugar in to a form of fat known as triglycerides while additionally driving higher levels of uric acid, a typical waste product discovered in urine and stool. also a lot uric acid can easily develop metabolic mayhem resulting in obesity, type 2 diabetes and others healthiness conditions.
Studying mice, the researchers discovered raised uric acid and triglycerides in otherwise healthy and balanced mice that were fed a high-fructose diet regimen throughout pregnancy. Additionally, the mice made smaller sized fetuses and bigger placentas compared to those fed standard rodent chow.
Genetically, Moley said, a small fetus might come to be wired to grow a lot more after birth compared to a normal-sized fetus. “The physique tries to compensate for the small growth in utero,” Moley said. “These babies can easily come to be youngsters then adults struggling along with obesity and others healthiness problems.”
Maternal healthiness additionally might suffer. Metabolic issues caused by higher levels of uric acid and fat improve a woman’s risk of producing pregnancy complications such as preeclampsia — a potentially severe condition in pregnancy regularly marked by higher blood pressure, puffinessing and higher healthy protein levels in the urine — and gestational diabetes, Moley said.
To assess the relevance of the mouse data in pregnant women, the researchers examined the association between fructose and placental uric acid levels in a small controlled group of 18 women that underwent scheduled cesarean sections. The women had no disorders that would certainly have actually caused raised uric acid. “We discovered a correlation suggesting similar maternal and fetal effects occur in humans,” Moley said.
In the mouse model, researchers discovered that giving mice along with high-fructose levels the common drug allopurinol — a prescription medication that reduces uric acid — reversed the refined sugar’s negative maternal and fetal effects by cutting down the levels of uric acid in the placenta.
“The negative effect of excess fructose in people is most likely to lead to an exacerbation of the issues seen in the mice,” said Moley, that believes Extra research might lead to a prenatal screening test for measuring fructose levels. This can easily be determined by basic blood work.
Besides advising pregnant women to restriction fructose in their diets, treatment for those along with high-fructose levels might contain administering allopurinol, which crosses the placenta and generally is considered safe to take late in the second trimester or 3rd trimester throughout pregnancy, Moley said.
“Among the most effective means to make sure healthy and balanced maternal and fetal outcomes is by consuming natural foods,” she said. Future studies will certainly test the effectiveness of giving allopurinol to pregnant women as quickly as there is concern concerning fetal growth, Moley added.
The study’s lead author was Zeenat Asghar, a graduate student in molecular cell biology in the university’s Division of Biology and Biomedical Sciences.
