Bad News for Latte Lovers: Discover the Surprising Reasons Why Coffee and Milk May be Harmful

Welcome to this blog post on why is coffee and milk bad.

For some of us, coffee is the fuel that keeps us going throughout the day.

For others, it’s more about the experience – the coffee shop, the aroma, the taste.

But have you ever wondered if your coffee habit could be doing more harm than good?

The answer is complicated.

The health effects of coffee and milk, or more specifically, the combination of coffee and milk, have been studied extensively.

1. Coffee is naturally acidic

I’m not a coffee drinker but from what I understand, it’s not the coffee itself but what’s added to it that can make it unhealthy.

For example, some people like to add a lot of sugar to their coffee which can be bad for your health.

Another example would be if you were to drink an iced coffee with milk and sugar in it.

The milk and sugar would make the coffee unhealthy because of how much of them are in the drink.

It is also important to note that coffee is naturally acidic.

This means that it can wear down your tooth enamel and make your teeth more prone to cavities.

Acidic foods and drinks can also cause heartburn or indigestion.

2. Milk has a neutral pH

Milk has a neutral pH.

This means that it is not acidic or alkaline.

This is important because acid is bad for teeth enamel and alkaline can upset the stomach.

Coffee, on the other hand, has an acidic pH.

The acid in the coffee can wear down tooth enamel and the alkaline in the milk can upset the stomach.

The combination of the two can be problematic for some people.

3. The ideal pH for coffee is between 5.5 and 6.5

If the pH level of your coffee is too high, it can lead to an imbalance in the body’s acid-base levels.

This can cause a number of health problems, including stomach upset, nausea, heartburn, and even tooth decay.

The ideal pH for coffee is between 5.5 and 6.5. If your coffee has a higher pH level, it is likely due to the type of water used to make the coffee.

Hard water has a higher pH level, so if you are using hard water to make your coffee, it will have a higher pH level as well.

4. The pH of milk is 7.6

The pH of milk is 7.6, which is slightly alkaline.

Milk is a rich source of calcium and other nutrients, making it an important part of a healthy diet.

However, milk can also be harmful to coffee.

Coffee and milk have different pH levels, which can affect the flavor and overall quality of your coffee.

Milk is an emulsion, and as such, its proteins can easily be precipitated by acidic substances such as coffee.

This will result in your coffee appearing cloudy and tasting worse.

For this reason, it is generally not recommended to add milk to coffee.

5. When milk is added to coffee, the coffee becomes more alkaline

The addition of milk to coffee is a time-honored tradition that has been enjoyed by people around the world for centuries.

It is a simple way to make a cup of coffee more creamy and smooth, as well as to add a touch of sweetness.

However, the addition of milk to coffee can also have some negative effects.

For one, it can make the coffee more alkaline, which can affect the flavor.

Additionally, it can also lead to the coffee being more bitter, since milk has a more neutral flavor.

The best way to avoid these negative effects is to use milk that has been specifically formulated for coffee, such as the type that is sold at coffee shops.

These types of milk are usually more acidic, which helps to balance out the flavor of the coffee.

In conclusion, while the addition of milk to coffee can be a great way to enjoy a cup of coffee, it is important to be aware of the potential negative effects that it can have on the flavor.

One should always use the right type of milk in order to avoid these effects.


Conclusion: if you want to avoid the bitter taste of coffee, try adding some milk to your cup.

But be careful, because the acidity of the coffee can affect the pH of the milk.

If you want to maintain the perfect pH for your coffee, try adding some neutral pH- adjuster to your cup.
