While coffee does not contain cholesterol, it can affect cholesterol levels. The diterpenes in coffee suppress the body's production of substances involved in cholesterol breakdown, causing cholesterol to increase. Specifically, coffee diterpenes may cause an increase in total cholesterol and LDL levels.

Read More »Studies have identified a risk of coffee raising a person’s serum cholesterol levels, although it may depend on the brewing method. Unfiltered coffee and French press coffee may raise cholesterol levels, while instant coffee and filter coffee are less likely to affect them. The risk of heightened serum cholesterol levels also depends on how much coffee a person drinks and how sensitive they are to caffeine. This article discusses how certain oils in coffee can affect serum (blood) cholesterol levels, the risks and benefits associated with drinking coffee, and tips on managing cholesterol levels.

Share on Pinterest Westend61/Getty Images Study results on the association between coffee drinking and higher levels of serum cholesterol are mixed, according to a 2001 research review. A more recent 2016 study suggests that coffee consumption is linked to higher cholesterol levels, although the effects vary depending on the type of coffee and the sex of the individual. However, according to older research from 1997, it is not the amount of caffeine in coffee that may affect cholesterol levels but rather the oils that naturally occur in the coffee bean. These natural oils, also known as diterpenes, are cafestol and kahweol. The Institute for Scientific Information on Coffee (ISIC) agrees that both oils can raise total and low-density lipoprotein (LDL) cholesterol levels, although the amount of diterpenes in coffee varies with the brewing method. For example, if a person makes coffee using paper filters, most of the diterpenes remain in the filter. However, in unfiltered coffee, more of the diterpenes pass through into the coffee. Also, Scandinavian boiled coffee, Turkish coffee, and French press coffee can increase cholesterol, according to a 2011 study . Scandinavian and Turkish coffee are unfiltered, while coffee made with a French press passes through a metal filter that allows more of the diterpenes to pass into the brew than paper filters. According to the ISIC, other types of brewed coffee contain varying levels of diterpenes and therefore have various effects on cholesterol levels: Espresso: This type of coffee has about half the amount of diterpenes found in unfiltered coffee. Because people generally drink small servings of espresso, it will likely have little effect on cholesterol. This type of coffee has about half the amount of diterpenes found in unfiltered coffee.

Instant coffee: This coffee type contains very few diterpenes, so it should not raise cholesterol. What is cholesterol? Cholesterol is a fat-like substance that plays many essential roles in the body at healthy levels. When LDL cholesterol levels are too high, plaque builds up in the arteries. If the plaque accumulates enough to obstruct blood flow, it becomes dangerous, as it can increase the risk of a heart attack or stroke. Cholesterol travels through the bloodstream as part of molecules called lipoproteins. There are two main types of lipoproteins in the blood: LDL: Some people call this “bad” cholesterol. It plays a key role in plaque buildup in the arteries. Some people call this “bad” cholesterol. It plays a key role in plaque buildup in the arteries. High-density lipoprotein (HDL): Some people call this “good” cholesterol. It helps remove cholesterol from the body. While coffee does not contain cholesterol, it can affect cholesterol levels. The diterpenes in coffee suppress the body’s production of substances involved in cholesterol breakdown, causing cholesterol to increase. Specifically, coffee diterpenes may cause an increase in total cholesterol and LDL levels. It is important to note that dietary cholesterol is not strongly linked to LDL levels. Instead, diets high in saturated and trans fats can increase cholesterol in the blood. However, research into dietary cholesterol is ongoing.
