Coffee, a beloved beverage for many, is often shunned by others. Its primary competitor, tea, is frequently touted for its superior health benefits, appealing to those seeking a healthier lifestyle. However, the truth is that tea's health benefits are only as good as its preparation, which can sometimes include as much sugar as a can of soda. To truly appreciate coffee, one must understand the core value of tea: the brewed leaf itself is the only healthful component. Everything else is indulgence.
Contrary to popular belief, coffee beans themselves offer numerous health benefits. However, the culture surrounding coffee, much like the culture of tea, includes many unnecessary additions. Espresso machines, for example, produce a highly concentrated form of regular coffee. Then there's the all-consuming vice: sugar. Along with cream, sugar dilutes the benefits of coffee, turning the brew into a sugary drink. But this is no different from tea. The bean is the essential part.
Coffee is rich in the B vitamin niacin and has been shown in recent research to have antioxidant-like effects on the body by eliminating free radicals. According to a study published in the Journal of Nutrition, coffee is one of the largest sources of antioxidants in the Western diet (1). However, these benefits only arise with balanced consumption. Too much cream and sugar can be detrimental, while excessive coffee intake poses long-term hazards.
Caffeine can wreak havoc on the nervous system, but it is not synonymous with coffee. Different types of coffee, prepared in various ways, yield different levels of caffeine content. Serving size also plays a role. For those sensitive to caffeine, decaffeinated coffee is an obvious alternative. However, this may downplay the positive impacts of the drink.
| Coffee Type | Caffeine Content (mg per 8 oz) |
|---|---|
| Drip Coffee | 95 |
| Espresso | 63 (per 1 oz shot) |
| Instant Coffee | 62 |
| Decaf Coffee | 2-5 |

A cup of coffee can be prepared in several ways, each affecting its health benefits and caffeine content.
The standard method used by drip machines yields a good amount of caffeine, and the filter traps out many of the volatile fatty acids in the bean. This method is generally considered one of the healthier ways to prepare coffee.
Using a French press, which lacks a filter, retains the acids in the brew. Some claim this method enhances the coffee's flavor, but it also means more fatty acids are consumed.
The pressurized water in an espresso machine does not filter out most of the volatile acids and increases the caffeine content. This method is popular for its strong flavor and quick preparation time.
For those who refuse to switch to decaffeinated coffee, instant coffee granules contain less caffeine and fatty acids compared to their quality counterparts. Instant coffee can be a suitable option for the balanced drinker.
While coffee offers numerous benefits, overconsumption can lead to several health issues. Excessive coffee intake has been linked to stomach ulcers due to the acids present in the brew. According to the American Journal of Clinical Nutrition, high coffee consumption can also lead to a deficiency in other essential vitamins and minerals (2). However, these risks are primarily associated with long-term, abusive drinking habits. A daily cup poses no threat to the average person.
In summary, coffee, when consumed in moderation and prepared correctly, can offer numerous health benefits. It is rich in antioxidants and essential vitamins, and different preparation methods can cater to various health needs and taste preferences. By reducing the amount of cream and sugar, one can enjoy a risk-free, casual cup of coffee.
