For instance, someone's total cholesterol may be high, but this may be due to very high HDL ("good cholesterol") cholesterol levels,—which can help prevent heart disease (the test is mainly concerned with high LDL, or "bad cholesterol" levels). So, while a high total cholesterol level may help give an indication that there is a problem with ...
What is a healthy cholesterol level? New study finds high levels of “good cholesterol,” or HDL, may not protect against heart disease, especially for Black adults.
Total cholesterol is defined as the sum of HDL, LDL, and VLDL. Usually, only the total, HDL, and triglycerides are measured. For cost reasons, the VLDL is usually estimated as one-fifth of the triglycerides and the LDL is estimated using the Friedewald formula (or a variant): estimated LDL = [total cholesterol] − [total HDL] − [estimated ...
The average amount of blood cholesterol varies with age, typically rising gradually until one is about 60 years old. There appear to be seasonal variations in cholesterol levels in humans, more, on average, in winter. [3] These seasonal variations seem to be inversely linked to vitamin C intake. [4] [5]
Researchers presented the results at the American Heart Association's annual meeting, and it could be a total game-changer when it comes to alcohol consumption. So bottoms up -- responsibly and if ...
Cholesterol is not always bad. It's a vital part of the cell wall and a precursor to substances such as brain matter and some sex hormones.

This dietary fiber works by forming a gel-like substance in the gut, which can help reduce cholesterol levels, particularly low-density lipoprotein (LDL) cholesterol, often referred to as "bad ...
Human iron metabolism is the set of chemical reactions that maintain human homeostasis of iron at the systemic and cellular level. Iron is both necessary to the body and potentially toxic. Controlling iron levels in the body is a critically important part of many aspects of human health and disease.
