The acidity and alkalinity of coffee and its effects on the body
Coffee is an indispensable drink in many people's daily life. It has a strong aroma and unique taste. However, do you know the acidity and alkalinity of coffee and its impact on health? This article will explore this topic.
What is pH?
The pH value is a measure of how acidic or alkaline a solution is, ranging from 0 to 14. Lower values indicate a more acidic solution, while higher values indicate a more alkaline solution. 7 is considered neutral.
pH of coffee
According to research data, regular black coffee generally has a lower pH value, between 4.85 and 5.10. This means that coffee is slightly acidic.
Strong Acid and Stomach Upset
Due to its low pH value and the presence of a large number of organic compounds (such as chlorine atoms, nitro groups, etc.), excessive intake of high-concentration or cooled coffee may cause stomach discomfort, such as heartburn, acid reflux, etc. This is because strong acidic substances can irritate the gastric mucosa and increase gastric acid secretion.
Effects of Caffeine on the Body
In addition to its acidity and alkalinity, coffee contains a substance called caffeine, which is a natural stimulant that promotes the activity of the nervous system and improves concentration and alertness.
However, consuming too much caffeine can lead to a range of adverse reactions. It can cause increased heart rate, insomnia, anxiety and digestive problems. In addition, long-term and high-intake caffeine has been linked to high blood pressure, heart disease and other health problems.
Ways to reduce the impact on your body
Although drinking black coffee may bring some discomfort or health risks, there are several ways to reduce its effects on the body:
- Opt for a low-acid or neutral brewing method: Using low-acid coffee beans or opting for a neutral brewing method, such as cold brew coffee, can reduce acidity.
- Moderate intake: Control the amount of caffeine you consume per day, it is recommended not to exceed 400 mg (about 4 cups).
- Drink with food: Drinking coffee with food can help slow down its irritation on the stomach.
- Dilution: If you find yourself allergic to espresso, try diluting it.
in conclusion
Overall, although coffee is a weak acid and contains the stimulant caffeine, you can still enjoy its benefits if you consume it in moderation and take appropriate measures. You can reduce its impact on your health by choosing low-acid or neutral brewing methods, consuming in moderation, drinking with food, and diluting it. Of course, in any case, please always decide whether it is appropriate to drink coffee based on your personal situation and doctor's advice.
