BONN: A new study suggests that consuming oats for just a few days can have a surprisingly strong impact on cholesterol levels.
Researchers at Germany’s University of Bonn conducted a study in which adult participants were placed on a low-calorie diet consisting almost entirely of oatmeal for two days.
According to a university press release, all participants in the study were diagnosed with metabolic syndrome — a condition associated with an increased risk of diabetes and cardiovascular disease.
Metabolic syndrome typically includes symptoms such as obesity, high blood pressure, elevated blood sugar levels, and high levels of blood lipids (fats).
A total of 32 participants were instructed to consume boiled oatmeal prepared with water three times a day, amounting to approximately 300 grams daily.
They were allowed to add only fruits or vegetables to their meals and consumed roughly half of their usual daily calorie intake.
A control group was also assigned a low-calorie diet; however, their diet did not include oats.
While both groups experienced health benefits due to reduced calorie intake, researchers observed a notably greater improvement in cholesterol levels among those who followed the oat-based diet.
Remarkably, the positive effects were still evident six weeks after the short-term dietary intervention.
Researchers believe that soluble fiber in oats — particularly beta-glucan — may play a key role in reducing cholesterol by limiting its absorption in the digestive system.
The findings highlight how even brief dietary adjustments can produce meaningful and lasting improvements in cardiovascular risk factors.
