As a follow up to my recent post on coffee, I thought I would revisit the Italian study published 5 years ago. Many of you will have missed or forgotten it.
"Our study aimed at evaluating in a population cohort the effect of Italian-style coffee consumption on prostate cancer risk ..."
It's a rare coffee study, in that it was concerned with preparation method.
"“Caffè espresso” and “moka” and their combinations with milk “caffè latte,” “cappuccino” and “macchiato” are the most widely used recipes for preparing ground coffee in Italy."
"... Italian-style coffee is prepared using unfiltered methodologies with high-pressure hot water (about 90°C, “caffè Espresso”) or boiling water (“caffè moka”)24 that may imply lower loss of bioactive compounds."
{Note that milk casein itself acts as a filter.}
I stopped using paper filters years ago (but not before I was diagnosed.) There used to be warnings about metal coffee filters, since volatile coffee oils end up in the cup. And it is certainly true that the drinking experience is different & may take adjusting to. Anyway, I assumed that paper filters might be removing useful micro-nutrients, so I stopped using them.
"6,989 men of the Moli-sani cohort aged ≥50 years were followed for a mean of 4.24 ± 1.35 years and 100 new prostate cancer cases were identified. The European Prospective Investigation into Cancer and Nutrition-Food Frequency Questionnaire was used for the dietary assessment and the evaluation of Italian-style coffee consumption. "
"Multiadjusted analysis showed that the subjects at highest consumption (>3 cups/day) had 53% lower prostate cancer risk as compared to participants at the lowest consumption (0–2 cups/day) ..."
