And it shows that consuming unfiltered coffee, which contains the lipid cafestol, raised serum cholesterol. "Advise patients concerned about low density lipoprotein cholesterol to prefer paper filtered or instant coffee over French press, Greek or Turkish, or boiled coffee, because cafestol in unfiltered coffee raises cholesterol." The heart association in 2025 had advised children to avoid caffeine, and had in the past said that adults could derive benefits from coffee but that drinking two or more cups a day could double the risk of heart death in people suffering from severe hypertension.
