Different types of fat affects heart and metabolism

The Truth About Dietary Fats: How the Fats You Eat Impact Your Heart and Metabolism

When it comes to nutrition, not all fats are created equal. For adult women striving for better health, understanding the difference between types of dietary fats—and how they affect your body—can be empowering and transformative.

Why the Type of Fat Matters

Overeating, especially when it comes to fats, can have a range of effects on your heart and metabolic health. But the kind of fat you consume makes a big difference.

Saturated fatty acids (SFAs), commonly found in animal products and processed foods, have long been associated with increased levels of atherogenic lipoproteins—these are the particles in your blood that can contribute to plaque buildup in your arteries, raising your risk for heart disease.

On the other hand, polyunsaturated fatty acids (PUFAs), found in foods like nuts, seeds, and fatty fish, have a very different effect. When excess energy in your diet comes from PUFAs instead of SFAs, research shows that levels of atherogenic lipoproteins actually decrease. This means your risk for heart disease and other cardiometabolic problems may be lower when you choose PUFAs over SFAs.

The Science Behind the Fats

Saturated Fats (SFA):

Raise LDL (“bad”) cholesterol and atherogenic lipoproteins, increasing heart disease risk.

Polyunsaturated Fats (PUFA):

Lower LDL cholesterol and atherogenic lipoproteins, supporting heart health.

Monounsaturated Fats (MUFA):

Found in olive oil and avocados, these also support healthy cholesterol levels.

What Does This Mean for You?

If you’re looking to protect your heart and improve your metabolism, focus on replacing saturated fats with polyunsaturated and monounsaturated fats in your diet.

This could mean:

- Swapping butter for olive oil or canola oil

- Choosing fatty fish like salmon instead of red meat

- Adding nuts and seeds to your meals for healthy fat sources

Takeaway

The fats you eat play a crucial role in your overall health. By making mindful choices—favoring PUFAs and MUFAs over SFAs—you can help reduce your risk of heart disease and support a healthier metabolism. Remember, small changes in your daily eating habits can lead to big benefits for your long-term well-
