Oats Boost Heart Health, Study Finds
A recent study suggests that eating oats for a short time can significantly improve cholesterol levels. Conducted by researchers at the University of Bonn in Germany, the trial focused on adults who followed a reduced-calorie diet made mostly of oatmeal for two days.
The study involved 32 participants, all of whom dealt with metabolic syndrome, a set of conditions that heightens the risk of diabetes. This includes high body weight, high blood pressure, elevated blood sugar levels, and higher blood lipid levels. The participants ate oatmeal prepared in water three times daily, totaling 300 grams, while keeping their caloric intake at about half of their usual amount. They could only add fruits or vegetables to their meals.
A control group followed a similar reduced-calorie diet but without oats. While both groups saw benefits, those eating oats experienced a “significant” improvement in cholesterol levels. After six weeks, these results did not change.
Marie-Christine Simon, a junior professor involved in the study, noted that those on the oat diet achieved a 10% reduction in LDL, known as “bad” cholesterol. Participants also lost an average of two kilos and saw a slight drop in blood pressure.
The researchers suggested that the oat-based diet positively affected gut bacteria, leading to these benefits. The findings were published in the journal Nature Communications.
Simon emphasized that a short-term oat diet repeated regularly could be a useful way to manage cholesterol levels and help prevent diabetes. She expressed interest in exploring whether repeating this oat-focused diet every six weeks could provide lasting preventive effects.
Nutritionist Robin DeCicco, who was not part of the study, supported the findings. She explained that oats are beneficial due to their high fiber content, which supports helpful bacteria in the gut. This leads to compounds that reduce “bad” cholesterol.
Oats are a whole grain and are low in saturated fat while being rich in fiber and plant-based protein. “These factors contribute to a heart-healthy diet,” DeCicco noted.
However, she did advise caution for individuals who are diabetic or pre-diabetic, as oats are high in carbohydrates. Those watching their blood sugar should consider opting for lower-carb foods, focusing on vegetables and nuts.
Megan Wroe, a registered dietitian from California, agreed that oats can lower cholesterol, especially in those with prior elevated levels. She mentioned that people who suddenly increase their oat intake might experience cramping or indigestion if their diets were previously low in fiber.
Wroe encouraged eating oats regularly but suggested choosing steel-cut or rolled varieties, using fruit for sweetness, and maintaining balanced meals by adding protein sources like chia seeds or Greek yogurt.
In conclusion, incorporating oats into your diet may not just be a tasty choice; it could also support heart health and help manage cholesterol levels.
