New scientific findings
A scientific study has shown that peanut consumption is associated with changes in blood lipid composition, which may contribute to improving metabolic processes and lowering the risk of type 2 diabetes, through its effect on specific types of fatty acids and lipid molecules in the body.
Details of the research experiment
The Euronews news network reported on Monday that the study, conducted by researchers from the German Institute of Human Nutrition Potsdam-Rehbr眉cke in collaboration with researchers from the University of Barcelona, Spain, was published in the American Journal of Clinical Nutrition on September 17. It revealed a distinctive lipid signature associated with peanut consumption, which is statistically linked to a reduced risk of type 2 diabetes.
The study included a six-month dietary experiment involving 63 healthy adults aged 18 to 33, randomly divided into three groups. The first group consumed 25 grams of roasted peanuts daily with their thin skin, the second group consumed 32 grams of peanut butter, and the third group consumed a preparation containing peanut oil for comparison.
Data analysis and results
Researchers used advanced techniques to analyze blood lipids, aiming to detect changes not revealed by traditional cholesterol tests, and to identify lipid compounds affected by peanut consumption. The results showed increased levels of two types of very long-chain saturated fatty acids, known by the symbols C22:0 and C24:0, and their appearance within specific types of fats, including ceramides. Ceramides are molecules that form part of cell membranes and play a role in regulating their functions.
To evaluate the long-term health implications of these changes, researchers analyzed data from the German EPIC-Potsdam study, which included more than 27,000 people and recorded 774 cases of type 2 diabetes and 545 cases of cardiovascular diseases. The comparison showed an association between the lipid signature resulting from peanut consumption and a reduced risk of type 2 diabetes, while no similar association was found with cardiovascular diseases.
The role of body mass index
The analysis showed that body mass index statistically explains a large part of the relationship between this lipid signature and the reduced risk of diabetes, suggesting that these results may be linked to body weight and metabolic processes associated with fat accumulation. Lead author Ines Dominguez Lopez stated that the changes are not limited to increased levels of certain fats, but include a more complex reshaping of their composition. Researcher Matthias Schulze noted that identifying this signature could help understand the relationship between dietary fat quality and health outcomes related to metabolism.
The results highlight the importance of studying the impact of food components on metabolic processes, while emphasizing that peanut consumption alone does not guarantee diabetes prevention, but can be part of a balanced diet that supports overall health. Type 2 diabetes is a chronic disease that occurs when the body does not use insulin effectively or does not produce enough of it, leading to elevated blood sugar levels, which can cause health complications if not controlled.
