In a nutshell

This paper studied how diet patterns affect the risk of coronary heart disease.

 

Some background

Coronary heart disease occurs when there is a build-up of substances like fat in the blood vessels. This increases the risk of heart attacks. Individual foods, such as red meat and saturated fats (fats found in animal products), have been shown to increase the risk of coronary heart disease. It is suggested that studying an overall diet pattern would be more useful in identifying risk factors. 

Methods & findings

17418 residents of the southeastern United States were asked about their diet and medical history. Five different diet patterns were found. The first diet, "convenience pattern" included food such as pasta, pizza, Mexican, and Chinese food. The second diet, "plant-based", focused on fruits, vegetables, poultry and fish. The third diet, "sweets pattern", included mostly sweets and desserts. The fourth diet, "Southern diet", included mostly fried food, processed meat and eggs. The fifth diet, "alcohol and salads" included mostly alcohol, vegetables and salads. 
 
A greater consumption of the Southern diet was associated with greater occurrence of high blood pressure, abnormal fat levels, and diabetes.

There was a total of 536 cases of acute (sudden) coronary heart disease over an average 5.8 years of follow-up. Participants with the highest consumption of the Southern pattern were 56% more at risk of acute coronary heart disease. No other dietary pattern was associated with the increased risk of acute coronary heart disease.

The bottom line

The authors concluded that a Southern pattern diet of fats, fried food, eggs, organ meats, processed meats, and sugary drinks was associated with increased risk of acute coronary heart disease.

What’s next?

Discuss your diet options, such as consuming less of a "Southern diet" pattern, with your doctor.
