Q. Youâve written a bout coffee raising cholesterol unless it is filtered to remove cafestol and kahweol. My brother has been using only Keurig coffeemakers for the past 10 years. He is experiencing high cholesterol and memory problems. Do the Keurig devices raise cholesterol, since they do not have filters for the coffee grounds? A. Keurig-type machines that use âK-cupsâ or âpodsâ to make a single serving of coffee have become extremely popular. If you take a K-cup apart, you will find a filter in it. We donât know whether that filter removes cafestol and kahweol. Consequently, we canât say with certainty that your brotherâs coffee habit affects his cholesterol. We suspect, though, that itâs less likely to pose problems.
