Oil is a kitchen staple, and an essential ingredient in a wide range of recipes. However, while there are plenty of healthy oils that can be a great part of a balanced diet in moderation, choosing the wrong variety could set you up for a number of health risks—and may even increase your risk of diseases like cancer. Knowing which ones to avoid is a major key to maintaining a healthy diet.
To shed some light on some oils that could damage your health, we spoke to Krutika Nanavati, a registered dietitian and nutritionist. She warned against hydrogenated vegetable oils and soybean oil. Learn more about the specific risks of each below.

1. Soybean Oil
Soybean oil, commonly used in cooking and food processing, has a high polyunsaturated fat content, primarily consisting of omega-6 fatty acids. While these fatty acids are essential for the body, an excessive intake of omega-6 compared to omega-3 fatty acids can lead to an imbalance and potentially contribute to inflammation, impacting heart health.
"Soybean oil is a widely used vegetable oil extracted from soybean seeds for cooking and food processing. Soybean oil is high in omega-6 fatty acids, which in excess can promote inflammation in the body. This inflammation has been linked to chronic conditions such as heart disease, cancer, and autoimmune diseases," Nanavati notes.
Numerous alternatives are available for cooking oil, allowing you to make choices that promote both your overall health and heart well-being. "When selecting cooking oils, consider fatty acid composition and smoke point. Olive, avocado, and coconut oils are recommended for healthy cooking due to their high smoke point and balanced fatty acids. Olive oil contains monounsaturated fats and antioxidants, reducing the risk of heart disease."
2. Hydrogenated Vegetable Oils
Hydrogenated vegetable oils, often used in processed foods to enhance shelf life and texture, can have detrimental effects on health, particularly heart health. The hydrogenation process involves adding hydrogen to liquid vegetable oils, transforming them into semi-solid or solid fats.
Nanavati elaborates further and says, "Hydrogenated vegetable oils are produced by adding hydrogen to liquid vegetable oils to turn them into solid fats. Commonly found in processed and packaged foods, these oils are often used for frying and baking. One of the main issues with hydrogenated oils is their high content of trans fats. Trans fats are known to increase the risk of heart disease, stroke, and type 2 diabetes. These fats can elevate harmful cholesterol levels (LDL) and reduce beneficial cholesterol levels (HDL), resulting in blocked arteries and ultimately leading to heart disease."
Healthy Oils
Does this mean you have to give up cooking with oil altogether? Of course not! There are plenty of healthy alternatives to these potentially harmful ingredients. In fact, the right oils can be a great source of the healthy fats your body thrives on.
Extra virgin olive oil, avocado oil, and even sesame oil are all great options in moderation. By switching inflammatory vegetable oils for these smart alternatives, you could be making a major difference in your overall health.
