Better Health with Filtered Coffee, Here's Why!
Drinking coffee is already part of our daily life, and about 30-40% of the population drinks coffee every day. As reported by the current coffee statistics from the International Coffee Organization, it is estimated that 1.4 billion cups of coffee are consumed each day worldwide.
Now as we all know, coffee has been linked to several health benefits such as it may lower the risk of type 2 diabetes and cardiovascular disease, extending lifespan, and reducing blood cholesterol.
Filtered Brewed Coffee is Better For Your Health
A recent observational study was published by the European Journal of Preventive Cardiology in April 2020 looked into 508,747 men and women who are healthy coffee drinkers between the ages of 20 and 79 over a 20-year period and found that unfiltered brewed coffee was associated with higher mortality than filtered brewed coffee, and filtered brewed coffee was associated with lower mortality than no coffee consumption at all. The goal of the study was to identify whether the filtered brewing method is linked with any death and cardiovascular mortality.
Here's why -- filtered coffee was associated with a 15% reduced risk of death from any cause. Particularly, the risk of cardiovascular death was decreased in filtered brewed coffee by 12% in men while 20% lowered in women compared to no coffee consumption at all. Additionally, people below 60 in particular, who drank 1-4 cups of filtered brewed coffee daily showed the lowest mortality rate.
One of the authors of the study, Dag Thelle, also recommends shifting to filtered brewed coffee, especially for people who are worried about high blood cholesterol. He also advised avoiding unfiltered brewed coffee for those who already have high blood cholesterol.
Studies have shown that unfiltered coffee contains 30 times more compounds of diterpenes, mainly kahweol and cafestol (coffee oils), which can elevate bad cholesterol levels. Therefore, use filtered drip coffee limit coffee consumption to less than 4 cups a day and avoid drinking unfiltered coffee too often.
The study concluded that filtered drip coffee is the best choice. We suggest keeping your coffee simple and choose filtered, black coffee without any additional creamers/milk and sugar.
Types of Filters
To give clarity on what type of filter should be used since there are cloth, metal, and paper filters. The recommended filter for your drip coffee should be a paper filter.
Here's the difference between the three. Let's start with the metal filter, this type of filter isn't absorbent therefore coffee oils are still present in your coffee but it's the easiest to clean and can be used for a long time when cleaned and maintained properly.
Cloth filter do capture coffee grounds and even micro-grounds but barely absorbs coffee oils and is difficult to clean and maintain for longer use, however, these first two filters would help lessen paper pollution and waste.
On the other hand, paper filters are tightly woven and absorbent to oils and micro-grounds which means that it traps the coffee oils that raise bad cholesterol and other compounds that increase cardiovascular disease and leaves you a clean cup of coffee, plus it gives you a light, crisp and flavorful coffee for your palette to experience. Be responsible for throwing your paper filter properly.
Types of Paper Filtered Coffee
We have 3 popular paper filtration methods and the coffee they leave in the cup:
1. Pour-Over Method (Cafec Flower Dripper / V60 / Kalita Wave) - standard paper filters (cone-shaped mostly, some are trapezoid) for these brewing equipment tend to yield a clean, bright and crisp cup because it filters out the majority of the coffee oils extracted during the brewing process.
2. Chemex - thick paper filters are used for brewing coffee in Chemex resulting in a minimal amount of coffee oils in your cup, usually none at all. This produces clarity of flavors especially for delicate coffees such as single-origin light roast and medium roast coffees.
3. Aeropress - this is your on-the-go coffee gear where ever you go. The small, round paper filter for Aeropress is thin which will not filter out a high level of coffee oils.
When choosing the first filtered brewing gear, pour-over is recommended. Here's Why Pour-Over Brewing Method is great to begin your coffee journey and start drinking a healthy cup of coffee every day.
