A surprisingly simple dietary intervention-eating only oats for two days-may substantially lower “bad” LDL cholesterol, according to new research from the University of Bonn. Published in Nature Communications, the study reveals that this short-term diet not only reduces cholesterol but also demonstrates lasting metabolic benefits weeks after the regimen ends. The findings echo a historical practise, reminiscent of “oat cures” used in the early 20th century, and highlight the potential of targeted nutrition to proactively manage cardiovascular health.
A short-term oat diet can significantly reduce levels of harmful LDL cholesterol, and the positive metabolic effects can be measured for weeks afterward, according to a new study from the University of Bonn.
Researchers at the University of Bonn have found that a two-day oat-based diet can substantially lower LDL cholesterol levels, with benefits extending for several weeks after the diet ends. This finding highlights the potential of simple dietary changes to impact cardiovascular health.
Study Shows: Two Days of Oats, Weeks of Benefit

The research, recently published in the journal Nature Communications, demonstrates that just two days following a strict oat diet leads to a significant reduction in LDL cholesterol. The positive effects on metabolism remained measurable even weeks later.
The Bonn research revisits a historical approach to health. At the beginning of the 20th century, physician Carl von Noorden successfully used the oat cure to treat patients with diabetes.

How Beta-Glucan Works Its Magic
The cholesterol-lowering power of oats comes from a soluble fiber called beta-glucan. This fiber forms a gel-like substance in the digestive tract, triggering several key processes.
- Binding of Bile Acids: The gel binds to bile acids, which are then excreted from the body.
- Cholesterol Consumption: The liver draws on cholesterol from the blood to create new bile acids – lowering LDL levels.
- Stable Blood Sugar: The gel also slows the absorption of sugar and fats.
Scientists estimate that approximately 3 grams of oat beta-glucan per day is needed to reduce LDL cholesterol by up to 10 percent.
How the Strict Two-Day Cure Works
The diet is straightforward, but requires commitment. For two consecutive days, the diet consists solely of oats.
- Meals: Three portions per day.
- Amount: 75 to 100 grams of oatmeal, cooked in water or unsweetened tea.
- Allowed: Small amounts of low-sugar fruits (berries) or vegetables for variety.
- Forbidden: Sugar, salt, and fats.
The cure is intentionally low in calories. Participants in the Bonn study lost an average of two kilograms (approximately 4.4 pounds) – a welcome side effect.
Who is the Cure Suitable For?
The oat cure may be a natural intervention for certain groups:
- Individuals with mildly to moderately elevated LDL levels.
- People with metabolic syndrome (obesity, high blood pressure, impaired glucose metabolism).
- Individuals with type 2 diabetes may benefit from the blood sugar-regulating effects.
Important Note: This cure is not a long-term solution, but rather an intensive starting point. Individuals with chronic illnesses (especially kidney disease) or those taking blood sugar-lowering medications must consult their doctor before starting.
Simple Nutrition as Powerful Medicine
The study results underscore the growing role of nutritional medicine. Targeted, short-term dietary measures can have profound and lasting effects.
Researchers also believe that a positive change in the gut microbiome may play a role. Regular “oat days,” perhaps once a month, could become a simple strategy for long-term control of the risk of cardiovascular disease.
