Red Meat and Heart Disease: Good or Bad For Heart Health?
Questions surrounding the consumption of red meat and its contribution to heart disease has led to varied research. A main source of the nutrient choline is red meat and carnitine is derived of amino acids which are protein building-blocks. Red meat is a rich source of protein. Hence this exploration into whether or not we have another reason to reduce red meat consumption.
What is choline?
Choline is a nutrient that plays a role in liver function, normal brain development, muscle movement, nerve function, metabolism, and sleep. Choline is also involved in absorbing and removing fat and cholesterol from the body, reducing chronic inflammation, and the kidneys control of water balance.
What is carnitine?
Choline and Your Health
Are you even familiar with the B vitamin choline? There is a good chance you are not. The Institute of Medicine didn’t even establish a dietary reference intake for this nutrient until 1998.
Choline, like magnesium, plays a role in just about every bodily system. Two compounds are derived from choline – acetylcholine and lecithin. Acetylcholine is a neurotransmitter for the peripheral and central nervous systems. Acetylcholine may protect again certain age-related dementias. Lecithin is a more generic term encompassing yellowish-brown fat tissue.
Choline Sources
The body can produce choline in small amounts, but not in large enough quantities to support good health. You must consume choline from dietary sources. Choline can be found in many foods, such as:
Choline and Memory
I previously shared some information on the potential link between choline and coronary artery disease. Here’s a little more info on choline you may find useful:
Acetylcholine and lecithin are derived from the B vitamin choline. Acetylcholine may protect against some forms of age related dementia. In the early 1970’s and 1980’s, abnormal uptake of acetylcholine, synthesis, and release was identified in individuals with Alzheimer’s and Parkinson’s disease. However, there has been a lacks of strong experimental support to validate these findings in recent years.

Heart Disease and the B Vitamin Choline
A proposed link between the B vitamin choline and coronary artery disease is being explored. The relationship between choline and coronary artery disease (CAD) may involve the accumulation of homocysteine and the effect these concentrated homocysteine levels have on endothelial cells (inner layer of blood vessels).
Several studies indicate that homocysteine levels are a key contributor and primary risk factor for CAD. While on the flip side, several studies have shown no decreased CAD risk with a reduction in homocysteine levels.
So, the importance of choline in reducing the risk of coronary artery disease is debatable. Regardless, choline plays important roles in metabolism and normal cell function, so it’s worth knowing a little about this B vitamin.
