Understanding LDL and HDL Cholesterol

LDL, or low-density lipoprotein, is crucial for transporting triglycerides and cholesterol in the body, essential for hormone production and human life. Individuals with extremely low LDL levels, like in Smith-Lemley-Optertz syndrome, face severe health consequences. Studies show higher LDL levels can protect against infections. HDL, high-density lipoprotein, also plays a vital role in the immune system by transporting molecules in the body. Both LDL and HDL are necessary for human physiology, challenging the misconception that they are harmful.
