What exactly are lipids?
Lipid mediators are chemical messengers that are released in response to tissue injury. When a harmful invader, such as bacteria, enters the body, some lipid mediators are released to help stimulate cells involved in the immune response while others help “turn off” an immune response when it is no longer needed. Current evidence suggests that lipid mediators, including prostaglandins (PGs), leukotrienes, and lipoxins, play an essential role in the different phases of inflammation. Inflammation occurs when white blood cells flood to a site of injury in the body. The increase in these cells, which fight against disease-causing substances and/or heal the body, causes swelling in the body. Inflammation gradually subsides once the injurious stimulus has been destroyed or broken down by the body. Cholestoral is a naturally occurring substance in the body and is comprised of lipids. Cholesterol is separated into two types, high-density lipoprotein (HDL) and low-density lipoprotein (LDL). In a
