A new study found that consuming sardines regularly helps prevent type 2 diabetes from occurring
According to a new study by Diana Diaz Rizzolo, lecturer and researcher at Universitat Oberta de Catalunya (UOC), nutrients in sardines help protect against type 2 diabetes, which affects around 14% of the Spanish population over 18 years of age. Faculty of Health Sciences and August Pi i Sunyer Biomedical Research Institute (IDIBAPS).
The study enrolled 152 patients aged 65 and over who were diagnosed with prediabetes and enrolled in a nutritional program designed to reduce their risk of developing the disease.
Only the intervention group added 200 grams of sardines to their diet each week, which is the equivalent of two cans of sardines in olive oil. 37% of the members were at high risk of having diabetes at the start of the study and only 8% were at very high risk after a year.
Of the group that did not include sardines in their diet, 27% of the members were at high risk of developing diabetes. After one year, 22% were in the same category.
Improvements were also observed in other important biochemical parameters, such as a decreased insulin resistance index (HOMA-IR), increased “good” cholesterol (HDL), increased hormones that accelerate the breakdown of glucose (adiponectin), and decreased triglycerides and blood pressure. amongst other things.
“As we get older, restrictive diets (in terms of calories or food groups) can help prevent diabetes from occurring. However, the cost-benefit ratio is not always positive, as we have found in other studies, ”explained doctor Rizzolo. “However, the results suggest that we can achieve an equally significant preventive effect in the younger population.”
“Nutrients can play an essential role in the prevention and treatment of many different pathologies, but their effects are usually caused by the synergy between them and the food in which they are contained. Sardines therefore have a protective element because they are rich in the above nutrients, while nutrients taken in isolation in the form of dietary supplements do not work to the same extent. “
“Because it affects the regulation of many biological processes and we need to understand whether they played a role in this protective effect against diabetes 2,” she added. They also initiated studies to modulate the expression of certain genes related to inflammation that could play a role in the occurrence of diabetes 2 and various other diseases.
The full study was published in the Clinical Nutrition Journal.
