The Truth About Healthy Fats VS Unhealthy Fats

Distinguishing the difference between Healthy Fats and unhealthy fats can make the most significant impact on your health and well being.

Fat has been the primary fuel source for humans, both from storage and as the predominant macronutrient in our diet since the beginning of time.

Unfortunately, the association of the word fat or fats has been maligned as unhealthy for decades based on flawed science, propaganda, and shrewd marketing practices.

Before I bash names (Ancel Keys), it’s essential to distinguish the difference between unhealthy and Healthy Fats.

Dietary Fats

Dietary fats come in all different forms, sizes, and shapes. They each offer an assortment of healthful benefits and in some cases, not so healthy by compromising your health. (We will discuss more on this later).

Saturated Fats

Despite its lousy repetition due to shrewd conventional wisdom, saturated fats are an excellent source of caloric energy. There is no scientific proof of adverse health effects when consumed outside of the Standard America Diet.

Saturated fats are commonly found in animal foods (meats, eggs, butter, and cream) and some tropical oils such as coconut and palm. This type of fat is extremely temperature stable, making it resistant to oxidative damage when exposed to heat, light, or oxygen.

This makes saturated fats the preferred choice for cooking.


Monounsaturated fats such as macadamia nuts, avocado, olives, and extra virgin olive oil are universally regarded as healthy. These fats are known for enhancing cardiovascular and immune function while also protecting against heart disease.

These fats are less temperature stable than saturated fats and should not be used for high-temperature cooking. But should still be consumed in abundance!


Polyunsaturated fats (also known as PUFAs) contain more fluid than the fats mentioned above, hence allowing these fats to stay in liquid form at room temperature or when refrigerated.

PUFAs are highly susceptible to damage from light, heat, and oxygen.

The most common types of PUFAs found in the Standard American Diet are all vegetable oils (canola, soy, corn, safflower, and sunflower) along with fake butter spreads and can be found in most processed foods.

When these fats are exposed to even the slightest routine exposure, they can wreak havoc on your endocrine system. They cause widespread oxidative damage to your molecules by preventing healthy hormone and immune function.

The Take-Away

Due to flawed science and propaganda, Ancel Keys was able to use questionable studies to condemn saturated fats. He helped shape the Standard American Diet (SAD) Pyramid, and in return, the rates of obesity, heart disease, and cancer (despite the most advanced health care) are proof that the SAD is a complete failure.

While saturated fats are the best choice, do note when consuming these in the presence of excessive carbohydrates (from the SAD) they can be potential troublesome. However, when consumed by themselves there is no sciencific study showing that saturated fats are unhealthy or wreak havoc.
