Have you ever wondered about the impact of the acidity levels in your favorite morning beverages, coffee, and tea, on your digestive and oral health? In this article, we will delve into the science behind the acidity of coffee and tea and how it can affect our bodies. Prepare to discover some surprising facts about these beloved drinks!
Revealing the Acidity: Coffee vs Tea
Both coffee and tea contain caffeine, which provides a stimulating effect. However, when it comes to acidity, black coffee and black tea are almost identical. Coffee typically has an average pH of 4.5 – 6, while black tea ranges from 4.9 – 5.5. The acidity levels in these two popular beverages are quite comparable.

On the other hand, green tea stands out with its significantly lower acidity. With an average pH of 10, it is a staggering 100,000 times less acidic than black tea. The difference is truly remarkable!
Understanding the Notion of Acidity
When we refer to the “acid content” of coffee or tea, we are talking about the presence of certain particles that lend a slight sour or tangy taste to these drinks. Coffee derives its acidity from organic acids like chlorogenic acid, quinic acid, and citric acid, which contribute to its distinct flavor and aroma. This is why we describe it as “acidic” because it shares some similarities in taste with sour foods like lemons or vinegar. However, the acidity in coffee is usually quite subtle and may go unnoticed by some individuals.
What is pH and Its Relationship to Beverage Acidity?
Now, let’s dive a little deeper into the concept of acidity and explore the pH scale. pH is a measure of how acidic or basic a substance is. Here’s a table showcasing the pH levels of common everyday liquids:
| Substance | pH |
|---|---|
| Black Coffee | 4.5 – 6 |
| Black Tea | 4.9 – 5.5 |
As you can see, coffee and tea fall on the slightly acidic side of the scale, but they are still considered relatively mild compared to other substances.
How Do Coffee and Tea Affect the Stomach?
There is no concrete evidence to suggest that drinking coffee or tea has long-term negative effects on the stomach. However, it’s important to note that certain individuals with sensitive stomachs may be more affected by the acids present in these beverages, as they can stimulate stomach acid production. It ultimately depends on your personal sensitivity.

In the case of gastroesophageal reflux disease (GERD), acid reflux, or erosive esophagitis (EE), multiple studies have shown no association between coffee drinking and these conditions. The same goes for tea. Several research studies have found zero evidence linking tea consumption to GERD.
Does Coffee Affect Digestion?
A recent study shed light on some interesting findings about coffee consumption. Here are five key takeaways:
- Coffee doesn’t improve digestion.
- Coffee isn’t linked to indigestion.
- Coffee doesn’t usually cause stomach discomfort.
- Coffee can help stimulate bowel movements.
- The caffeine in coffee may lower the risk of liver cancer.
However, it’s important to remember that everyone’s body is unique, and what works for one person may not work for another. It’s crucial to listen to your body and understand its individual needs when it comes to coffee consumption.

Are Coffee and Tea Bad for Your Teeth?
Yes and no. Numerous studies have been conducted to explore the relationship between coffee, tea, and tooth health. Some studies have suggested that drinking coffee can be harmful to your teeth, while others have found that it may actually provide some protection against tooth damage. The effect of coffee consumption on periodontal health remains a topic of debate, as coffee contains complex components that may have either beneficial or negative impacts.
However, there is good news for coffee lovers! Cold brew coffee, which has a lower acidity level compared to hot-brewed coffee, can be a better choice for those with sensitive teeth or stomachs.
The Health Benefits of Coffee and Tea
Coffee and tea both offer numerous health benefits that contribute to overall well-being. Coffee, in particular, has been found to have anti-inflammatory and antioxidant effects, which can help protect against various diseases and potentially promote longevity. A comprehensive analysis of multiple coffee-related studies revealed that drinking at least three cups of coffee can significantly reduce the risk of cardiovascular and coronary heart diseases, as well as strokes.
Tea, on the other hand, is often consumed for its health benefits. In a recent study involving half a million tea drinkers in the UK, it was observed that those who consumed at least two cups of tea per day had a 9% to 13% lower risk of death from any cause compared to non-tea drinkers. Increased tea consumption was also associated with weight loss, lower risk of death from cardiovascular disease, ischemic heart disease, and strokes.
Conclusion: Moderation is Key
In summary, while coffee and tea do not appear to have a significant impact on our digestive health, their effects on oral health are still uncertain. Coffee typically falls within the mildly acidic range on the pH scale, while the acidity of tea varies depending on the type.
It is worth noting that both coffee and tea have been shown to help lower the risk of death from heart disease, cardiovascular disease, and strokes. However, moderation is key when consuming these beverages to enjoy their health benefits without overindulging.
So, the next time you savor that cup of coffee or tea, rest assured that you are also partaking in a tradition that has been associated with positive health outcomes. Enjoy your favorite brew in moderation and raise a toast to your well-being!
