Red Meat Has Neural Effect on Cardiovascular Disease Risk Factors

Font : A-A+

Highlights
  • Red meat is a nutrient-rich food as a source of protein and bioavailable iron.
  • Previous studies state red meat consumption ups cardiovascular disease risk.
  • New research suggests consuming red meat above the recommended amounts does not increase heart disease risk factors.

Red Meat Has Neural Effect on Cardiovascular Disease Risk Factors

Red meat consumption above the recommended level does not affect short-term heart disease risk factors such as blood pressure, blood cholesterol.

"During the last 20 years, there have been recommendations to eat less red meat as part of a healthier diet, but our research supports that red meat can be incorporated into a healthier diet," said Wayne Campbell, professor of nutrition science.

While previous studies suggest that red meat consumption is linked to a higher risk of cardiovascular disease, they are not designed to show that red meat is causing heart disease. A review and analysis of past clinical trials were conducted to detect the cause and effect between eating habits and associated health risks.

Red Meat and Lowered Heart Disease Risk

Campbell, doctoral student Lauren O'Connor, and postdoctoral researcher Jung Eun Kim screened hundreds of related research articles, focusing on studies that met specific criteria including the amount of red meat consumed, evaluation of cardiovascular disease risk factors and study design. 24 studies that met the criteria were published in the American Journal of Clinical Nutrition .

The research study included mostly unprocessed beef and pork and found that 3 ounce serving of red meat three times per week did not worsen blood pressure and blood total cholesterol levels.

Campbell also said more analysis is needed as the evaluation of blood pressure and cholesterol are not the sole determinants for someone to develop cardiovascular disease. "It is also important to recognize that our findings are specific to selected indicators for cardiovascular disease risk," Campbell said. "Comparable research is needed to assess other health risk factors from clinical trials, including inflammation and blood glucose control."
