How does a high-fat diet affect blood pressure?

A high-fat diet is known to affect blood pressure largely through its impact on body weight, cholesterol levels, and vascular health. Consuming a diet high in saturated fats can lead to an increase in body weight, which is a significant risk factor for hypertension (high blood pressure). Additionally, high-fat diets can contribute to elevated levels of low-density lipoprotein (LDL) cholesterol and inflammation, both of which can impair blood vessel function and lead to increased vascular resistance.

As a result, the combination of weight gain, cholesterol changes, and potential inflammation can cause the heart to work harder to pump blood, resulting in an increase in blood pressure. Research has shown a correlation between high-fat diets and higher instances of hypertension, especially when the fats consumed are predominantly saturated or trans fats. Maintaining a balanced diet with healthy fats, like those found in avocados, nuts, and fish, is essential for supporting optimal blood pressure levels and overall cardiovascular health.
