Selenium is an essential mineral that is required in small amounts for the proper functioning of the human body, including the maintenance of a healthy immune system and thyroid function. While Selenium is known for its antioxidant properties and its role in reducing oxidative stress, the evidence regarding its impact on preventing or helping with Heart attack is limited and inconclusive.
Several observational studies have suggested that low Selenium levels may be associated with an increased risk of cardiovascular diseases, including Heart attack However, these studies do not establish a cause-and-effect relationship and are subject to various confounding factors. Additionally, the results of randomized controlled trials, the gold standard in medical research, have not consistently demonstrated that Selenium supplementation reduces the risk of Heart attack or improves cardiovascular outcomes.
It is important to note that Selenium supplementation should be undertaken with caution and under the guidance of a healthcare professional. Excessive Selenium intake can be toxic and may lead to adverse health effects. As of my knowledge up until September 2021, the current medical research does not provide strong evidence that Selenium is beneficial for preventing or helping with Heart attack Therefore, maintaining a balanced diet, regular physical activity, and managing other established risk factors like high blood pressure, smoking, and high cholesterol levels remain the best strategies for preventing heart attacks.
