Keeping all other factors (e.g. water temperature, extraction time) the same, does grind size affect the LDL cholesterol levels in French press coffee? If so, how are the two related?

  • Could you please take a look at these two: coffee.stackexchange.com/questions/413/… and coffee.stackexchange.com/questions/2422/… ? – MTSan Sep 26 '18 at 8:31
  • @MTSan I'm familiar with those, but neither touch on the role of grind size given a French press (or other non-paper non-pressure brew method). I think it's conceivable grind size may impact the amount of oil (thus LDL) in the final product, but I'm looking for studies testing that hypothesis. – JJJ Sep 26 '18 at 11:36
  • Increasing extraction may increase LDL level if coffee does not immediately emit all its cholesterol in the beginning of extraction. Then, finer grind means more cholesterol. However, I'm unaware of the extraction dynamics of the cholesterol of coffee. – MTSan Sep 26 '18 at 13:03
  • Not really much to study there. The finer the grind, the higher the extraction, the more oils are present in the unfiltered coffee. Thus higher impact on LDL cholesterol levels. I doubt it has a huge impact, but logic dictates that it has at least some marginal effect. – avocado1 Sep 26 '18 at 13:40
  • There was apparently a study that done on the effects of grind size on lipid extraction. I can tell you the results without having read the paper (can't access it), but if you want to buy it here is the link: tib.eu/de/suchen/id/BLCP%3ACN081430365/… – avocado1 Sep 26 '18 at 13:55
