Heart disease is one of the most common diseases worldwide. It is estimated that one in four deaths in the United States is caused by heart disease. People are constantly searching for ways to prevent heart disease, and one way is through diet.

The impact of high-fat dairy on heart health has been a topic of much debate. Some studies suggest that high-fat dairy can increase the risk of heart disease, while others suggest that it can have a protective effect.

In this article, we will review the research on this topic to better understand the impact of high-fat dairy on heart health.

What is high-fat dairy?

High-fat dairy refers to dairy products that contain a high percentage of fat. Examples of high-fat dairy include butter, whole milk, cream, and cheese.

These foods are often high in saturated fats, which have been linked to an increased risk of heart disease.

Studies suggesting that high-fat dairy can increase the risk of heart disease

Several studies suggest that consuming high-fat dairy can increase the risk of heart disease.

For example, a study published in the American Journal of Clinical Nutrition found that consuming high-fat dairy was associated with a higher risk of heart disease. The study tracked the diets of over 3,000 adults for 15 years and found that those who consumed high-fat dairy had a 64% higher risk of dying from heart disease than those who consumed low-fat dairy.

Another study published in the European Heart Journal found that consuming high-fat dairy was associated with a higher risk of coronary heart disease.

The study tracked the diets of over 9,000 adults for 12 years and found that those who consumed high-fat dairy had a 28% higher risk of developing coronary heart disease than those who consumed low-fat dairy.

Studies suggesting that high-fat dairy can have a protective effect on heart health

While some studies suggest that high-fat dairy can increase the risk of heart disease, others suggest that it can have a protective effect.

For example, a study published in the American Journal of Clinical Nutrition found that consuming high-fat dairy was associated with a lower risk of heart disease. The study tracked the diets of over 27,000 women for 11 years and found that those who consumed high-fat dairy had a 28% lower risk of developing heart disease than those who consumed low-fat dairy.

In addition, a study published in the Journal of Nutrition found that consuming high-fat dairy was associated with a lower risk of hypertension.

The study tracked the diets of over 5,000 adults for 10 years and found that those who consumed high-fat dairy had a 23% lower risk of developing hypertension than those who consumed low-fat dairy.

Why might high-fat dairy have a protective effect on heart health?

It is not fully understood why high-fat dairy might have a protective effect on heart health, but there are several theories.

One theory is that the fat in dairy products may help to reduce inflammation in the body, which is a key risk factor for heart disease. Another theory is that the high levels of calcium in dairy products may help to lower blood pressure, which is another risk factor for heart disease.

Should you consume high-fat dairy?

The research on the impact of high-fat dairy on heart health is conflicting, so it is difficult to make a definitive recommendation.

However, it is generally recommended that people limit their intake of saturated fats, which are found in high-fat dairy products. The American Heart Association recommends that people consume no more than 5-6% of their daily calories from saturated fats.

If you do choose to consume high-fat dairy, it is important to do so in moderation. Choose low-fat or non-fat versions of dairy products whenever possible, and limit your intake of high-fat dairy products such as butter and cream.

It is also important to choose dairy products that are rich in other nutrients, such as calcium and vitamin D.

The bottom line

The impact of high-fat dairy on heart health is a complex topic, and the research is conflicting. While some studies suggest that high-fat dairy can increase the risk of heart disease, others suggest that it can have a protective effect.

If you choose to consume high-fat dairy, it is important to do so in moderation as part of a balanced diet.
