Unsaturated fats are lipids that are considered to be heart-healthy and associated with reduced inflammation.
- Healthy fats are those that are unsaturated. They lower inflammation, reduce cholesterol, and normalize heart rhythms, according to research.
- They are composed of carbon atom chains with a reduced number of hydrogen atoms connected due to the presence of one or more double bonds. They are often liquid at ambient temperature due to their structure.
- Saturated fats, on the other hand, are "saturated" with hydrogen atoms, which means they have the most hydrogen atoms surrounding the carbon atoms. At room temperature, saturated fats are normally solid.
- Because they raise bad cholesterol, saturated fats have long been associated with an increased risk of cardiovascular disease (LDL).
- Unsaturated fats, which are liquid at room temperature, are regarded as healthy fats because they have a range of positive effects on health, including <u>lower blood cholesterol levels, less inflammation, stable cardiac rhythms,</u> and more.
