Participants on the red meat diet mostly ate beef as their protein source, while the participants on the white meat diet mostly ate chicken. The study did not look at fish or processed meats. There is less pressure on consumers to do the same with its white counterpart. Moreover, while high SFA juxtaposed to low SFA increased LDL cholesterol, primary outcomes suggest no discernible differences between the effects of red and white meat. The participants who were eating higher levels of saturated fats were equal in terms of showing bad cholesterol levels, regardless of their diets of red or white meat.
However, data supporting this view is "somewhat incomplete", Krauss continued. It has always been assumed that meats such as chicken is better for your cholesterol levels than beef, but the latest research indicates that poultry has an equally bad effect on the health of your heart.
But he said the results were notable as they indicated that restricting meat altogether, whether red or white, is more advisable for lowering blood cholesterol levels than previously understood.
The American Heart Association says people should get just 5 to 6 percent of their calories from saturated fats and advises people to replace foods high in saturated fat with healthier options to lower blood cholesterol levels.
White meat has been held up as the healthier, leaner alternative - fueling the uptick in consumption of poultry, as sales of burgers and chops dwindle.
Plant proteins had the healthiest impact on blood cholesterol, the study results showed.
The researchers at Children's Hospital Oakland Research Institute (CHORI) have published their findings in the American Journal of Clinical Nutrition. "Their effects on cholesterol are identical when saturated fat levels are equivalent".
Still, since public health agencies have long recommended that people try to cut down on red meat and switch to white meat or vegetables as their major source of protein, this study's findings do carry some important implications.
"Indeed, other effects of red meat consumption could contribute to heart disease, and these effects should be explored in more detail in an effort to improve health", Krauss said.
Dietitians now believe that high saturated fat content of red meat increases the risk of cardiovascular diseases, yet all the theories go in vain as no further tests have been done to prove the above-stated theory. They split them into two broad groups, with one group getting a diet high in saturated fats, while the other had a diet low in them. Even though cholesterol is a waxy substance made by your liver and found in your cells, having too much of the substance in your body can cause it to accumulate in your arteries, increasing your risk of coronary heart disease.
It's also possible that there are other factors about red meat that can affect cardiovascular health, he said.
