Saturated vs Unsaturated: What’s the Difference?
Saturated and unsaturated are two terms that you may have heard in relation to fats and oils. These two types of fats have very different physical and chemical properties, which affect their health benefits and risks. In this article, we’ll explore the difference between saturated and unsaturated fats.
Saturated fats are fats that are solid at room temperature, such as butter or bacon grease. These types of fats are commonly found in animal products, such as meat, dairy, and eggs. Saturated fats are called “saturated” because they are saturated with hydrogen atoms. This means that every carbon atom in the fat molecule is bound to a hydrogen atom.
While saturated fats are a major source of energy and essential for our body’s processes, they also have been linked with an increased risk of heart disease, obesity, and other health issues. They can raise your LDL (“bad”) cholesterol levels, which can cause plaque buildup in your arteries and increase your risk of heart attack or stroke.
Unsaturated fats, in contrast, are liquid at room temperature and come from plant-based sources, such as nuts, seeds, and vegetable oils. These types of fats are called “unsaturated” because they have at least one double bond between two carbon atoms. This double bond creates a kink in the molecule, which means there are fewer hydrogen atoms bound to the carbon atoms.
Unsaturated fats are often referred to as “healthy” fats because they can lower your LDL cholesterol levels and reduce your risk of heart disease. Omega-3 fatty acids, a type of unsaturated fat, have also been linked with numerous other health benefits, such as reducing inflammation, improving brain function, and decreasing depression and anxiety symptoms.
The Bottom Line
The main difference between saturated and unsaturated fats is in their chemical structure, which affects their physical properties and health benefits. While saturated fats are solid at room temperature and can raise your LDL cholesterol levels, unsaturated fats are liquid at room temperature and can lower your LDL cholesterol levels. Choosing healthier fats, like unsaturated fats, over saturated fats can have a positive impact on your health in the long run.
