Coffee ingredient analysis: From caffeine to polyphenols, exploring the secrets of coffee

Effects and effects of caffeine

Caffeine is one of the most well-known ingredients in coffee. It is a natural stimulant that can quickly refresh the mind, increase alertness and concentration. When we drink a cup of strong and mellow coffee, the caffeine contained in it will enter the blood circulation system in less than half an hour and be transmitted to the brain through the blood.

In the brain, caffeine blocks the binding of chemicals (aDEnosine) on specific receptors, thereby reducing drowsiness and increasing alertness. In addition, it can also promote the release of hormones such as adrenaline, which has an excitatory effect on various systems in the body.

Health Benefits of Polyphenols

In addition to caffeine, coffee is also rich in a variety of polyphenols, which have antioxidant, anti-inflammatory and anti-cancer effects.

The first is chlorogenic acids, which can help lower blood sugar and cholesterol levels and reduce the risk of cardiovascular disease. The second is caffeic acid and ferulic acid, which have antioxidant effects and can neutralize free radicals and protect cells from damage.

In addition, coffee is rich in bitter compounds, such as quinines and caffeine, which can stimulate the secretion of digestive juices, promote intestinal peristalsis, and have a certain diuretic effect when consumed in moderation.

Effects of different coffee types on component content

Different types of coffee have different content of ingredients. For example, espresso usually contains higher concentrations of caffeine and polyphenols. Low- or de-caffeinated coffee has most or all of the caffeine removed through special processing methods.

In addition, ingredients are adjusted during processing. For example, when making concentrated cold brew, polyphenols are more easily extracted than when brewing traditionally, so cold brew coffee usually contains higher polyphenol content.

Research on the relationship between coffee ingredients and health

Many studies have explored the relationship between coffee components and health. Some studies have shown that moderate coffee consumption can reduce the risk of chronic diseases such as cardiovascular disease, stroke and type 2 diabetes. Other investigations have found that excessive caffeine intake may cause problems such as anxiety, insomnia and gastrointestinal discomfort.

It’s important to note that everyone may react differently to coffee’s components. Some people are sensitive to caffeine and may experience discomfort even at low doses, while others may be able to tolerate higher doses without significant adverse reactions.

in conclusion

In summary, from caffeine to polyphenols, we can see that the various ingredients in coffee provide wakefulness and excitement while also bringing many benefits. However, coffee should be consumed in moderation and the appropriate type and processing method should be selected according to personal circumstances. For those who are sensitive to caffeine or have specific health problems, it is best to control intake under the guidance of a doctor.
