Contrary to popular belief, consumption of both red and white meat affects blood cholesterol levels equally, according to a study published in the American Journal of Clinical Nutrition.

Red meat consumption has been losing popularity over the past several decades due to concerns about its link to an increase in cardiovascular disease. As a healthier alternative to red meat, nutritional guidelines encourage the consumption of poultry. However, no comprehensive comparison has yet been made of the effects of red meat, white meat, and non-meat protein sources on blood cholesterol levels.

Scientists at the Children's Hospital of the Auckland Research Institute were surprised to find that high consumption of red meat or white meat from poultry raises blood cholesterol levels more than consuming comparable amounts of plant proteins. Moreover, this effect was observed regardless of the dietary intake of saturated fats (high levels of which increased blood cholesterol levels equally with any protein source).

"When we planned this study, we expected red meat to have a more adverse effect on blood cholesterol than white meat, but we were surprised that this is not the case - their effect on cholesterol is the same when saturated fat levels are equivalent." - said senior author Ronald Krauss (Ronald Krauss).

These results are particularly noteworthy in that they indicate the feasibility of restricting meat in general to lower blood cholesterol levels. The study found that proteins found in vegetables, dairy products and legumes are the most beneficial in terms of blood cholesterol levels.

In addition, the study found that consuming large amounts of saturated fat increases the concentration in the blood of large LDL (low-density lipoprotein, "bad" cholesterol) particles, which have a weaker association with cardiovascular disease than smaller particles.

Compared to a lean diet, red and white meat also increased the amount of large LDL particles. Therefore, it is possible to reevaluate accepted standards for LDL cholesterol levels as a measure of cardiovascular risk, since standard LDL cholesterol tests may primarily reflect coarse LDL particle levels.

“Our results indicate that the current recommendation to limit consumption of red and white meat should not be based solely on their effect on blood cholesterol levels. Indeed, other effects of red meat consumption may contribute to the development of cardiovascular disease, and these effects must be studied in more detail in order to improve health,”concluded Krauss.
