Key Takeaways
- Consuming oatmeal for just two days can reduce bad cholesterol levels by around 10%.
- This effect is linked to an increase in antioxidants in the bloodstream and changes in the gut microbiome.
- The cholesterol-lowering benefits from oatmeal may persist for up to six weeks.
Recent research suggests that oatmeal can influence cholesterol levels, partly by altering the gut microbiome, and these changes might extend over a month.
Eating Oatmeal Might Lead to Lasting Changes in Cholesterol Levels
A study published in a scientific journal found that participants who consumed primarily oatmeal for two consecutive days experienced a cholesterol reduction that lasted for at least six weeks.
This adds to existing research about the impact of oatmeal on cholesterol levels and highlights who might benefit from including it in their diet.
“We’ve known that oats help lower cholesterol, but it was mainly attributed to their fiber content,” a clinical nutritionist noted.
However, this new research suggests that oatmeal alters the gut microbiome in ways that could contribute to lowering cholesterol levels.
How Much Did Oatmeal Lower Cholesterol?
The study examined four groups of individuals. One group consumed a large portion of oats for two days, while the second group ate a similar diet without oats. The third group included oats in one meal daily over six weeks, and the last group followed a typical Western diet.
All participants had metabolic syndrome, characterized by factors like abdominal obesity, high lipid levels, high blood pressure, and high blood sugar.
The group that ate only oatmeal showed about a 10% decrease in low-density lipoprotein (LDL) cholesterol and an 8% decrease in total cholesterol. Notably, their cholesterol levels remained lower than they were at the start even six weeks later.
While these findings are promising, it’s worth noting that an oats-only diet is not advisable for the long term.
“This isn’t a complete diet, and while it can be followed for a short time, I wouldn’t recommend it for longer than 48 hours,” the nutritionist mentioned.
How Oatmeal Might Affect Your Gut Health
This isn’t the first research to link oatmeal consumption with lower cholesterol levels.
“Oats are beneficial for heart health, particularly in reducing LDL cholesterol, which is a major contributor to heart disease,” stated a cardiologist.
This study, however, presents new insights into oatmeal’s mechanism for lowering cholesterol. It indicates that oats boost antioxidants in the blood and positively alter gut bacteria.
Despite these advantages, there are limitations to what oatmeal can do for overall health, especially for those with heart issues.
“For individuals with high cholesterol and increased cardiovascular risk, a healthy diet alone is often not enough, and medications may be necessary,” the cardiologist added.
