For decades, we have been told that saturated fats are bad for our health. We have been advised to reduce our intake of foods that contain these fats, such as butter, cheese, red meat, and coconut oil.

The reason behind this advice is that saturated fats are believed to raise cholesterol levels in the blood and increase the risk of heart disease.

However, recent research suggests that the link between saturated fat and heart disease may not be as straightforward as we once thought.

In this article, we will explore the evidence behind the saturated fat myth and uncover the truth about these much-feared fats.

What are Saturated Fats?

Saturated fats are a type of fat that is typically solid at room temperature. They are found in animal products such as meat, dairy, and eggs, as well as in some plant-based foods such as coconut oil, palm oil, and cocoa butter.

Unlike unsaturated fats, which are liquid at room temperature, saturated fats are typically more stable and less prone to spoilage. This is why they have traditionally been used in cooking and food production.

The History of the Saturated Fat Myth

The idea that saturated fats are bad for our health dates back to the 1950s when researchers first identified a link between high cholesterol levels and an increased risk of heart disease.

This led to the hypothesis that consuming foods high in cholesterol and saturated fats would contribute to the development of heart disease.

Since then, numerous studies have been conducted to investigate this link.

In general, these studies have found that a diet high in saturated fats is associated with higher levels of LDL (or “bad”) cholesterol, which is a known risk factor for heart disease.

As a result of this research, public health authorities around the world have issued guidelines recommending that people limit their intake of saturated fats in order to reduce their risk of heart disease.

The Recent Evidence

In recent years, however, some researchers have begun to question the evidence behind the saturated fat myth. Several studies have suggested that the link between saturated fat and heart disease may be more complex than we once thought.

One of the main criticisms of the link between saturated fat and heart disease is that it is based on studies that have only looked at associations, rather than causation.

In other words, just because people who eat more saturated fats tend to have higher levels of heart disease doesn’t necessarily mean that the saturated fat is causing the heart disease.

Furthermore, some studies have found that replacing saturated fats with other types of fats, such as polyunsaturated fats, does not actually reduce the risk of heart disease.

This suggests that the relationship between fat intake and heart disease risk may be more nuanced than we once thought.

The Role of Cholesterol

Another important factor to consider when it comes to saturated fats and heart disease is cholesterol.

As we mentioned earlier, a diet high in saturated fats is associated with higher levels of LDL cholesterol, which is a known risk factor for heart disease.

However, recent research has shown that not all LDL cholesterol is created equal. There are actually two types of LDL cholesterol: small, dense LDL particles and large, fluffy LDL particles.

It is the small, dense particles that are most strongly associated with heart disease, whereas the large, fluffy particles are generally considered to be less harmful.

Interestingly, some studies have found that a diet high in saturated fats actually increases the proportion of large, fluffy LDL particles, which may help to explain why the link between saturated fat and heart disease is not as strong as we once thought.

The Bottom Line

So, what does all of this mean for our diets? Should we be avoiding saturated fats, or can we enjoy them in moderation?.

Overall, it seems that the evidence behind the saturated fat myth is not as clear-cut as we once thought.

While a diet high in saturated fats may contribute to higher levels of LDL cholesterol, it is not necessarily true that this will automatically lead to an increased risk of heart disease.

Furthermore, some studies have suggested that a diet high in saturated fats may actually have some benefits, such as improving insulin sensitivity and reducing inflammation.

As with most things in life, the key is moderation. While it’s probably not a good idea to start consuming large quantities of butter and red meat on a daily basis, there is no need to fear these foods either.

Enjoying them in moderation as part of a balanced diet is unlikely to do any harm, and may even have some benefits.
