Healthy Coffee Brewing

Based on recent scientific articles, the healthiest ways to brew coffee focus on reducing diterpenes, compounds in coffee’s natural oils that can raise LDL (“bad”) cholesterol. Here’s a breakdown:Key Findings from Recent Research:

• Filtered Coffee is Best: Multiple recent studies consistently point to paper-filtered coffee as the healthiest brewing method. The paper filter effectively traps most of the diterpenes (cafestol and kahweol), leading to lower levels in the final brew.

• Unfiltered Methods Have Higher Diterpenes: Brewing methods like French press, Turkish coffee, and some cold brews do not use a paper filter, allowing more diterpenes to pass into the coffee. These methods have been associated with increased LDL cholesterol levels in studies.

• Workplace Brewing Machines May Be Problematic: A recent study indicated that coffee brewed in some workplace machines had higher diterpene concentrations compared to home-brewed, paper-filtered coffee. This suggests that the filtration in these machines might not be as effective.

• Boiled Coffee Has the Highest Diterpenes: Traditional boiled coffee preparations, like Turkish coffee, contain the highest concentrations of diterpenes.

• Even Makeshift Filters Help: Research showed that even filtering boiled coffee through a sock significantly reduced diterpene levels, highlighting the importance of filtration.

• Impact on Heart Health: Studies suggest that regularly consuming unfiltered coffee might negatively impact cardiovascular health due to increased LDL cholesterol. Switching to paper-filtered coffee could potentially reduce this risk over time.

• Antioxidants Remain: While filtering reduces diterpenes, coffee brewed with methods like pour-over (using a paper filter) still retains significant antioxidant properties.Healthiest Brewing Methods:

• Pour Over (with paper filter): This method allows for control over brewing temperature and time while effectively filtering out diterpenes. Examples include using a Hario V60 or Chemex with paper filters.

• Drip Coffee (with paper filter): Standard electric drip coffee makers that use paper filters are a healthy option.

• AeroPress (with paper filter): This method uses pressure to brew coffee and can produce a clean cup with minimal sediment when used with a paper filter.Methods to Consume in Moderation (or with caution if you have cholesterol concerns):

• French Press: Retains coffee oils and diterpenes due to its metal mesh filter.

• Espresso: Contains high levels of diterpenes due to the fine grind and lack of paper filter.

• Cold Brew: While often perceived as less acidic, it still retains diterpenes as it typically doesn’t use a paper filter.

• Turkish Coffee/Boiled Coffee: Has the highest concentration of diterpenes.

• Coffee from some Workplace Brewing Machines: May have higher diterpene levels than home-brewed filtered coffee.Additional Tips for a Healthier Coffee Habit:

• Drink it Black (or with minimal additions): Adding excessive sugar, cream, or flavored syrups can negate some of the health benefits of coffee. A splash of milk is generally fine.

• Consider Bean Quality and Roast: Some sources suggest that lighter roasts might have higher antioxidant content.

• Moderate Consumption: Most studies showing health benefits point to moderate consumption (around 3-4 cups per day).In conclusion, if you are concerned about cholesterol levels and want the healthiest way to brew coffee based on current scientific understanding, opting for methods that use a paper filter, such as pour-over or a drip machine, is the most recommended approach.
