But in what scientists have called a ‘huge scientific discovery’, a new Spanish study published in Clinical Nutrition journal has discovered that the regular consumption of sardines helps to prevent the onset of type 2 diabetes.
Researchers enrolled 152 patients aged 65 years and older who had been diagnosed with prediabetes (blood glucose levels between 100-124 mg/dl) from three different medical centres.
All the patients were put on a nutritional programme that sought to reduce the risk of them developing the disease, but only one group added 200 grams of sardines to their diet every week (two cans of sardines in olive oil). The participants received a list of recipes including canned sardines and were advised to eat the sardine whole, without removing the bones, as these are particularly rich in calcium and vitamin D.
Of those that did not include sardines in their diet, 27% were at a high risk of suffering from diabetes at the start of the study. After one year, 22% were in the same category. Among those who included sardines in their diet, 37% were at a high risk of suffering from diabetes at the start of the study. After one year, only 8% remained at a very high risk.
Improvements were also seen in other important biochemical parameters, such as a reduced 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 others.
Diana D. Rizzolo, lead author, and lecturer and researcher of the Universitat Oberta de Catalunya's (UOC) Faculty of Health Sciences and the August Pi i Sunyer Biomedical Research Institute (IDIBAPS) said sardines should now be recommended by doctors, particularly to people over 65.
