The findings are <a href=\"https:\/\/www.nature.com\/articles\/s41467-026-68303-9\" target=\"_blank\" rel=\"noopener\" title=\"\">published<\/a> in the journal <em>Nature Communications<\/em>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Metabolic syndrome is defined by a combination of excess body weight, high blood pressure, elevated blood sugar and abnormal blood lipids. Together, those factors sharply increase the odds of developing type 2 diabetes, heart attack and stroke.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Bonn team wanted to revisit an old idea with modern tools. More than a century ago, German physician Carl von Noorden treated patients with diabetes using an oat-heavy diet and reported strong results. But as medications improved, that approach faded from view.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cToday, effective medications are available to treat patients with diabetes,\u201d Marie-Christine Simon, a junior professor in the Institute of Nutritional and Food Science at the University of Bonn, said in a news release. \u201cAs a result, this method has been almost completely overlooked in recent decades.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Simon, who is also part of the university\u2019s \u201cLife &amp; Health\u201d and \u201cSustainable Futures\u201d research areas, and her colleagues set out to test how a focused oat intervention would affect people with metabolic syndrome in a rigorous, randomized controlled trial.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Participants in the intensive oat group ate oatmeal boiled in water three times a day for two days, with only small amounts of fruit or vegetables allowed as additions. They consumed 300 grams of oatmeal per day \u2014 about 10.5 ounces \u2014 and roughly half their usual calories.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A control group followed a similar calorie-reduced diet for two days, but without oats.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Both groups saw health benefits from cutting calories. But the oat group stood out.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThe level of particularly harmful LDL cholesterol fell by 10 percent for them \u2013 that is a substantial reduction, although not entirely comparable to the effect of modern medications,\u201d Simon added. \u201cThey also lost two kilos in weight on average and their blood pressure fell slightly.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">LDL cholesterol is often called \u201cbad\u201d cholesterol because high levels can lead to fatty deposits, or plaques, in artery walls. Over time, those plaques can narrow blood vessels or rupture, triggering clots that may cause heart attacks or strokes. Even modest reductions in LDL are considered important for long-term cardiovascular health, especially in people already at high risk.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The researchers followed participants for six weeks after the two-day diet and found that the cholesterol improvements largely persisted, suggesting that a brief but intense dietary intervention can have lasting effects.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To understand why oats might be so powerful, the team looked beyond blood tests. They collected stool samples to analyze the gut microbiome \u2014 the trillions of bacteria that live in the digestive tract and help break down food, produce vitamins and generate a wide range of metabolic byproducts.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWe were able to identify that the consumption of oatmeal increased the number of certain bacteria in the gut,\u201d added lead author Linda Kl\u00fcmpen, a doctoral student in the Institute of Nutritional and Food Science under Simon&#8217;s supervision.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Those microbes do more than just help digest fiber. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cFor instance, we were able to show that intestinal bacteria produce phenolic compounds by breaking down the oats,\u201d Kl\u00fcmpen added. \u201cIt has already been shown in animal studies that one of them, ferulic acid, has a positive effect on the cholesterol metabolism. This also appears to be the case for some of the other bacterial metabolic products.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The team measured levels of a key phenolic compound called dihydroferulic acid in blood samples, which is thought to be produced when certain gut bacteria process oat components. These phenolic metabolites are believed to support a more favorable cholesterol profile and may also influence how the body handles blood sugar and inflammation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Other microbes in the gut appeared to help \u201cdispose of\u201d the amino acid histidine. In the body, histidine can be converted into a molecule suspected of promoting insulin resistance, a hallmark of type 2 diabetes. By shifting which bacteria thrive, the oat diet may indirectly reduce the buildup of such harmful compounds.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The study did not stop at the two-day intensive intervention. In a separate six-week trial, another group of participants with metabolic syndrome ate a more moderate dose of oats \u2014 80 grams per day \u2014 without strict calorie limits or other restrictions. That longer, lower-dose approach produced only small health effects, suggesting that intensity and calorie reduction may be key.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Taken together, the results point to a potential strategy that is both simple and low-cost: using short, repeated bursts of an oat-heavy, calorie-reduced diet as a metabolic reset.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cA short-term oat-based diet at regular intervals could be a well-tolerated way to keep the cholesterol level within the normal range and prevent diabetes,\u201d Simon added.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, she emphasized that more research is needed before doctors can confidently recommend this as a routine preventive measure. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cAs a next step, it can now be clarified whether an intensive oat-based diet repeated every six weeks actually has a permanently preventative effect,\u201d added Simon.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The trials were randomized controlled trials, considered the gold standard in clinical research. Participants were randomly assigned to oat or control diets. While it was not possible to keep people \u201cblind\u201d to what they were eating, the scientists who analyzed blood and stool samples, and those who measured blood pressure and weight, did not know which group each participant belonged to. That design helps reduce bias and strengthens confidence in the findings.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For now, the work adds to a growing body of evidence that what we eat can quickly and powerfully influence both our blood chemistry and our gut microbes \u2014 and that humble foods like oats may play an outsized role in protecting long-term health.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The study does not suggest that two days of oatmeal can replace cholesterol-lowering medications or other treatments. But it does hint that, under medical guidance, targeted dietary changes could become a valuable complement to standard care for people at high risk of diabetes and heart disease.<\/p>\n\n\n\n<div style=\"height:14px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Source: <\/strong><a href=\"https:\/\/www.uni-bonn.de\/en\/news\/017-2026\" target=\"_blank\" rel=\"noopener\" title=\"\">University of Bonn<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A University of Bonn study suggests that eating mostly oatmeal for just two days can significantly lower harmful LDL cholesterol in people with metabolic syndrome.
