From a nutritional perspective, coffee beans are actually a plant-based food, containing many compounds beneficial to the body. Therefore, many studies in recent years have shown that drinking coffee in moderation may be associated with reducing the risk of some chronic diseases.
chlorogenic acid
This is the most mentioned nutritional compound in coffee. Chlorogenic acid is a phytochemical with antioxidant and anti-inflammatory properties, and is also believed to help regulate blood sugar levels and support liver health.
Potassium ions
Due to its plant origin, coffee beans contain a certain amount of potassium. This mineral helps the body eliminate sodium, contributing to supporting the activity of the cardiovascular system.
Niacin (vitamin B3)
Coffee also provides a small amount of niacin - a B vitamin necessary for the functioning of the nervous system and the energy metabolism in the body.
Tannic acid
Coffee contains a small amount of tannic acid (a form of polyphenol), which is also one of the factors that creates the characteristic astringent taste of coffee. This compound has antioxidant properties, but if consumed a lot, it can affect the absorption of some minerals.
Caffeine
The caffeine content in coffee varies depending on the roasting level. Light roasted coffee usually retains more caffeine due to the short roasting time, while deep roasted coffee can reduce caffeine content slightly because it roasts longer. However, this difference is not too large and also depends on the coffee variety as well as the brewing method.
