Common foods may help people with Type 2 diabetes manage cholesterol, blood sugar and related health risks

Living with Type 2 diabetes requires continuous attention to blood sugar control, diet, physical activity and medication. While medicines remain an essential part of diabetes management, emerging research suggests that certain everyday foods and natural remedies may offer additional support in improving metabolic health.

Recent studies have explored the role of foods such as oatmeal and avocado, along with natural products like peppermint oil, in addressing some of the major health concerns associated with diabetes, including high cholesterol, uncontrolled blood sugar and elevated blood pressure.

Type 2 diabetes is a chronic metabolic disorder that develops when the body either does not produce enough insulin or becomes unable to use insulin effectively. This results in increased blood sugar levels and can raise the risk of complications involving the heart, kidneys, eyes and nerves.

Researchers are now focusing on how dietary choices can influence these risks. One study has suggested that oatmeal may have a significant impact on reducing LDL cholesterol, often referred to as “bad” cholesterol.

The research, conducted by scientists at the University of Bonn in Germany and published in Nature Communications in January 2026, examined whether a short-term oatmeal-based diet could improve cholesterol levels among people with metabolic syndrome. This condition shares several features with Type 2 diabetes, including high blood pressure, increased cholesterol, elevated blood sugar and excess body weight.

The researchers conducted two randomized controlled clinical trials and found that participants who consumed approximately 300 grams of oatmeal daily for two consecutive days experienced a nearly 10% reduction in LDL cholesterol levels. The participants were also allowed to include fresh fruits and vegetables while significantly reducing their overall calorie intake.

Interestingly, the cholesterol-lowering effect continued even six weeks after participants returned to their usual eating patterns. Scientists believe this may be linked to the high concentration of oat compounds, particularly phenolic substances, which interact with gut bacteria and may influence cholesterol metabolism.

However, experts caution that a short-term intensive oatmeal diet should not replace a balanced long-term eating pattern. Nutrition specialists emphasize that regularly including moderate amounts of oats, along with other fibre-rich foods and healthy plant-based nutrients, remains a practical approach for supporting heart and metabolic health.

Another study has highlighted the possible benefits of including avocados in the diet of people at risk of metabolic problems. Published in Current Developments in Nutrition in April 2026, the research analysed data from the Habitual Diet and Avocado Trial, which involved adults with increased waist circumference.

Participants who consumed one large avocado daily for six months showed a lower dietary glycemic load compared with those who consumed very little avocado. A lower glycemic load indicates that the overall diet may cause a slower rise in blood sugar levels after meals.

Experts suggest that avocados may support better metabolic health because they contain healthy monounsaturated fats, fibre and essential nutrients. Their ability to increase feelings of fullness may also help people reduce the intake of less nutritious foods.

Along with blood sugar and cholesterol problems, high blood pressure is another major concern among people with Type 2 diabetes. Studies have explored whether peppermint oil may have a role in supporting blood pressure control. The natural compounds present in peppermint may influence blood vessel relaxation and circulation, although researchers say more evidence is needed before it can become part of standard diabetes treatment.

Experts stress that no single food can cure or control diabetes by itself. Successful diabetes management still depends on a comprehensive approach that includes prescribed medicines, regular exercise, maintaining a healthy weight and following a balanced diet.

The latest findings highlight the growing importance of nutrition in diabetes care. Foods such as oats and avocados may provide additional health benefits, but they work best when combined with medical treatment and healthy lifestyle habits.
