Coffee drinking may lower the risk of type 2 diabetes and lower insulin resistance, which may improve heart health, according to a recent study that was published in the journal Clinical Nutrition.Almost 150,000 people from the Rotterdam Study and the UK Biobank were involved in the study. In this population, the study authors looked for associations between coffee consumption and diagnoses of type 2 diabetes. They also looked for associations between coffee consumption, insulin resistance, and inflammatory biomarkers. Both insulin resistance and diabetes can contribute to the development of heart conditions, including blood vessel damage and weight gain.The results showed that an increase of one cup per day in coffee consumption was linked to a 4–6% decrease in the chances of developing type 2.
