White meat refers to poultry and light colored meats. Where red meat meat refers to meat which are red in raw state.
The popular belief narrated in the past that red meat is not healthy as it contains some essential nutrients such as zinc, iron, Vitamin B12, and protein.
Past studies focused on consumption of white meat over red meat. Red meat are red in color due to presence of Myoglobin. Myoglobin is a protein which has a dark red color.
The red color which you sea in meat is not blood. It is a combination of Myoglobin and water. Some great examples of red meat are lomb, beef, pork, and bison.
White meat also contains Myoglobin protein but is less in quantity than red meat. Some examples of white meat are chicken, duck, turkey and other poultry products.
Which Meat is Better?
There is bad news for meat lovers. As recent study investigates that white meat such as chicken is harmful for cholesterol as compare to red meat such as beef, pork or lamb.
This new study contradicts the previous widespread beliefs that white meat is healthy for cholesterol level than red meat.
This belief is based on many observational studies that found a link between red meat and the risks of cardiovascular disease.
To investigate this link a team of researchers spearheaded by senior author Dr. Ronald Krauss, senior scientist and director of Atherosclerosis Research at the Children’s Hospital Oakland Research Institute in California.
Dr. Krauss and colleagues investigated the different intake of meats and their impact on lipids, lipoproteins that causes deposition of fat on the arteries.
To further investigate researchers divided participants into two groups first who consume high level of saturated fatty acids and second who consume low level of saturated fatty acids.
Researchers assigned the participants to a red meat group, white meat group and nomeat protein diet group.
The participants who were aged between 21-65 years old having BMI (Body Mass Index) 20-35 kilograms per square meter consumed the food for 4 weeks.
After the 4 weeks researchers measured LDL (Low density Lipoprotein) cholesterol, HDL (High density Lipoprotein) cholesterol, small/ medium LDL particles, and levels of apolipoprotein B.
Consuming white or red meat raised the cholesterol level more than consuming plant based protein diet. This was due to the increase in large LDL particles- Author stated.
The study concludes that vegetables, fruits, dairy and pulses have good impact on overall health. Author also stated that study doesn’t include fish, grass fed fish or processed meats.
