### Do Omega-3 Supplements Prevent Type 2 Diabetes? Omega-3 fatty acids are well-known for their heart-health benefits, but recent research suggests that omega-3 supplements may not help prevent type 2 diabetes. A review and meta-analysis published in the BMJ in August 2019 found that increasing omega-3 intake, whether through supplements or foods rich in these fats, does little to lower the risk of developing type 2 diabetes. The study analyzed data from over 58,000 participants in long-term trials. Despite some participants developing diabetes, those who consumed more long-chain omega-3 fats (like fish oils) had the same risk of diabetes as those who did not. The study concluded that taking fish oil supplements does not protect against diabetes, and high doses may even be harmful. Experts like Dr. Marilyn Tan from Stanford Health Care emphasize that no supplements have been definitively proven to reduce the risk of type 2 diabetes. The best way to prevent and manage diabetes is through lifestyle changes such as weight loss, a healthy diet, regular exercise, and avoiding sedentary behavior. While omega-3 supplements are generally considered safe, they are not regulated as strictly as traditional medications. Therefore, it may be more beneficial to focus on other healthy habits rather than relying on supplements. Eating oily fish, which is rich in omega-3s, can be a good alternative as it also provides other nutrients like protein, selenium, and vitamin D. In summary, while omega-3 fatty acids are beneficial for heart health, their role in preventing type 2 diabetes is unclear. It is better to focus on a balanced diet and regular physical activity for diabetes prevention.
