What Are Healthy Fats?
Healthy fats are beneficial dietary fats that support your heart, brain, hormones and overall well-being. These include monounsaturated and polyunsaturated fats, especially omega-3 fatty acids. Unlike trans fats and excess saturated fats, healthy fats help reduce inflammation, improve cholesterol and support long-term health.
Why Healthy Fats Matter
As someone who's experienced the ups and downs of diet trends over the years, I can tell you this: cutting out all fat is a mistake. Your body needs fat for energy, absorbing vitamins, making hormones and even thinking clearly.
Let’s break down the types, benefits and sources of healthy fats so you can use them confidently in your diet.
Types of Healthy Fats
1. Monounsaturated Fats (MUFAs)
These fats are heart-healthy and can help reduce bad cholesterol levels.
Sources:
-
Olive oil
-
Avocados
-
Almonds
-
Peanuts
-
Sesame oil
* Studies from Harvard School of Public Health support their benefits for cardiovascular health.
2. Polyunsaturated Fats (PUFAs)
This category includes omega-3 and omega-6 fatty acids, both essential for brain function and cell growth.
Omega-3 Fatty Acids:
Omega-6 Fatty Acids:
-
Sunflower oil
-
Corn oil
-
Soybean oil
* Balance is key most people get too much omega-6 and not enough omega-3.
3. Natural Saturated Fats (In Moderation)
Found in:
-
Coconut oil
-
Whole eggs
-
Grass-fed dairy
Although once feared, recent research suggests that moderate consumption of saturated fat from whole foods may not be as harmful as once believed.
Benefits of Healthy Fats
* Supports Brain Function
Your brain is 60% fat. Healthy fats are key to memory, focus and mental clarity.
*Promotes Heart Health
Omega-3s lower triglycerides, blood pressure and inflammation.
* Aids in Nutrient Absorption
Vitamins A, D, E and K are fat-soluble, meaning your body absorbs them only with fat.
* Balances Hormones
Fats help regulate sex and stress hormones crucial for women’s health, mood and metabolism.
