Polyunsaturated fat

Polyunsaturated fat is a type of healthy fat that is found in some foods like nuts, seeds, and fish. It's good for you because it can help keep your heart healthy by lowering bad cholesterol levels in your body. Unlike unhealthy fats like saturated fats and trans fats, polyunsaturated fats are good for you because they can also help reduce inflammation in your body, which can help prevent diseases like heart disease and diabetes.

Polyunsaturated fat is made up of two types of fatty acids: omega-3 and omega-6. These fatty acids are important for our body to function properly because we can't make them on our own.

Omega-3 fatty acids are found mainly in fatty fish like salmon, tuna, and sardines, as well as in plant-based sources like chia seeds, flaxseeds, and walnuts. These fatty acids are important for brain function and can also help reduce inflammation in the body.

Omega-6 fatty acids are found in vegetable oils, nuts, and seeds. These fatty acids are important for growth and development, but too much of them in our diet can cause inflammation in the body.

So, it's important to have a balance of both omega-3 and omega-6 fatty acids in our diet in order to stay healthy!
