In the U.S., more than half of people drink at least one cup of coffee daily (1). For the majority of us, it’s the familiar warmth, aroma, and taste, enhanced by its jolt of energy, that make this ritualistic habit one of the most anticipated parts of the day.

So it’s only more pleasing to learn that studies now suggest that drinking coffee daily offers the additional reward of long-term health benefits in the form of a lower body weight, better blood sugar control, and better cardiovascular health (1,2).

But how can something so common provide such health benefits? It has to do with coffee’s natural, health-benefiting components that are hard to get in the diet and from elsewhere.

Coffee’s flavor is actually made up of a naturally complex masterpiece of phytochemicals. It’s this complexity that makes it delicious, healthy, and when consumed in moderation can be an integral part of a healthy diet (1-3).

If you take a coffee bean and grind it down to its individual, naturally occurring components, here’s some of what you’ll find:

  • Caffeine – The most familiar component of coffee is an effective ergogenic aid that can enhance both cognitive and physical performance (5-8). It’s also thermogenic and, if taken before a workout, can improve mood, reduce the perception of effort, and increase the enjoyment of exercise (9).
  • Melanoidins Brown-colored compounds that result from the roasting process of coffee beans that have antioxidant properties (3).
  • Chlorogenic acid – A phenolic compound (a type of phytochemical) that is abundant in coffee with antioxidant and blood sugar-supporting properties (10, 11).
  • Niacin – Naturally present in coffee in small amounts, is an essential vitamin necessary for normal metabolism, and is important to overall cardiovascular health (12).
  • N-methylpyridinium (N-MP) – A compound that is a by product of roasting with potential benefits in supporting glucose utilization (14).
  • Trigonelline – A plant alkaloid responsible for a large part of the bitter flavor of coffee has antioxidative properties and is shown to support healthy blood sugar levels and nerve function (15, 16).
  • Pyrogallol – A crystalline phenol, with weak acid properties, that has been shown to support digestion and appetite (13).

Over your next cup of coffee, you might take a moment to contemplate how all these different phytochemicals create coffee’s complexity. Go ahead, take a sip of a preferably premium or organically roasted blend! Enjoy that flavor and what it has to offer your body.
