What types of fats are considered unhealthy?

Trans fats and excessive saturated fats are considered unhealthy due to their negative impact on cardiovascular health and overall well-being. Trans fats are artificial fats often found in processed foods, as they are created through hydrogenation, which extends shelf life but raises bad cholesterol (LDL) levels while lowering good cholesterol (HDL). This combination significantly increases the risk of heart disease, stroke, and type 2 diabetes.

Excessive saturated fats, primarily found in animal products and certain tropical oils, can raise LDL cholesterol levels as well, contributing to plaque buildup in arteries and elevating the risk for heart-related conditions, especially when consumed in large amounts. Though some recent discussions have nuanced the stance on saturated fats, health organizations typically advise limiting these fats in favor of healthier fat options.

In contrast, monounsaturated and polyunsaturated fats, including omega-3 and omega-6 fatty acids, are generally recognized as healthy fats that can promote heart health and contribute to overall nutrition when consumed in moderation. Healthy plant oils, along with those rich in omega fatty acids, are encouraged within a balanced diet. Thus, the correct identification of unhealthy fats is crucial for making informed dietary choices.
