Whew, I don't have to change my 12 cup a day habit.
Unfiltered coffees, also known as “boiled” coffees, do not employ a filter and include espresso, Turkish coffees, and French press coffees. Coffee contains many ingredients, most notably caffeine, chlorogenic acid, and chemicals called diterpenes.
I wrote about this way back in May 2016 so your doctor has no reason to not know about this and include it in your diet protocols.
Pressed coffee is going mainstream — but should you drink it?

Unfiltered coffee may increase mortality risk
April 23, 2020
People
who drank unfiltered coffee had a higher risk for mortality compared
with those who drank filtered coffee, according to a study published in
the European Journal of Preventive Cardiology.
“Our study provides strong and convincing evidence of a link between coffee brewing methods, heart attacks and longevity,” Dag S. Thelle, MD, PhD, professor in the department of public health and community medicine at the Institute of Medicine at the University of Gothenburg in Sweden, said in a press release. “Unfiltered coffee contains substances [that] increase blood cholesterol. Using a filter removes these and makes heart attacks and premature death less likely.”
Coffee consumption in Norway
Aage Tverdal, PhD, epidemiologist at the Norwegian Institute of Public Health, and colleagues analyzed data from 508,747 participants aged 20 to 79 years from Norway. Participants completed questionnaires on smoking habits, coffee consumption and formal education duration. Some of the questions pertaining to coffee consumption included method of brewing, type and number of cups per day.
Among participants, 59% reported they preferred filtered coffee, 20% preferred unfiltered coffee, 9% used both methods and 12% did not drink coffee.
During an average follow-up of 20 years, there were 46,341 all-cause deaths, 12,621 CVD deaths, 6,202 ischemic heart disease deaths and 2,894 deaths related to stroke.
Compared with no coffee consumption, the HRs for any death in men who consumed filtered coffee was 0.85 (95% CI, 0.82-0.9), 0.84 for men who preferred both filtered and unfiltered coffee (95% CI, 0.79-0.89) and 0.96 for men who consumed unfiltered coffee (95% CI, 0.91-1.01). For women, HRs for any deaths were 0.85 for filtered coffee (95% CI, 0.81-0.9), 0.79 for both filtered and unfiltered coffee (95% CI, 0.73-0.85) and 0.91 for unfiltered coffee (95% CI, 0.86-0.96).
HRs for CVD death in men were 0.88 for filtered coffee (95% CI, 0.81-0.96), 0.93 for filtered and unfiltered coffee (95% CI, 0.83-1.04) and 0.97 for unfiltered coffee (95% CI, 0.89-1.07). Women had an HR of 0.8 for filtered coffee (95% CI, 0.71-0.89), 0.72 for unfiltered and filtered coffee (95% CI, 0.61-0.85) and 0.83 for unfiltered coffee (95% CI, 0.74-0.93).
When researchers stratified by age, HRs increased for people aged 60 years and older. Compared with no coffee consumption, unfiltered coffee increased the HR for CVD death to 1.19 in men (95% CI, 1-1.41) and 0.98 for women (95% CI, 0.82-1.15).
The HR for death from ischemic heart disease and CVD increased when total cholesterol was excluded from the model. HR for ischemic heart disease mortality increased by 9% in participants who drank nine or more cups of unfiltered coffee per day.
