While a standard 8-ounce cup of coffee delivers about 95mg of caffeine, a similar serving of black tea contains only around 50mg.

Over 85% of American adults consume caffeine daily, but the actual amount in a "cup of coffee" can vary widely—from 60 to over 200 milligrams. The idea that 200 mg of caffeine equals one standard cup is a common misconception that overlooks the many factors influencing your daily brew.

An average cup of black tea contains about 40–70 mg of caffeine, but the level can vary significantly.

The answer lies not only in the tea plant itself but also in how it is processed and brewed.

According to a 2023 study published in *Science Reports*, consuming unfiltered coffee can significantly raise 'bad' LDL cholesterol levels compared to filtered varieties. So, the answer to which coffee has the least cholesterol doesn't lie in the bean itself, but in the brewing method used.

A meta-analysis published in the journal *ResearchGate* showed that drinking unfiltered coffee was associated with an increase in total and LDL cholesterol. This effect is directly related to diterpenes, the natural oils in coffee, which are affected by the brewing method used.

According to coffee scientists, all coffee beans naturally contain fats and oils, known as lipids, which can comprise up to 17% of a green bean's makeup.

Understanding this helps explain the sheen you might see on your cup and the nuanced flavors you taste.

According to the official Harney & Sons website, their teas typically contain between 40 and 60 milligrams of caffeine per cup, though this can vary significantly by type.
