Are Apples Acidic?

When it comes to the acidity of apples, there is some confusion. Many believe apples are acidic because many other popular fruits contain acids.

However, this is not true—apples are slightly alkaline with a pH of 6-7. This means that eating an apple will not adversely affect your teeth or your overall health.

Apples are an excellent source of vitamins and minerals that can help you maintain good health. They are rich in antioxidants that can help protect your cells from damage and dietary fiber, which aids digestion and helps to keep your digestive system functioning correctly.

What Makes Food Acidic or Alkaline?

When determining whether a food is acidic or alkaline, the most critical factor is its pH level. The pH scale ranges from 0 to 14, with seven being neutral. Anything below seven is considered acidic, and anything above seven is considered alkaline.

Apples have a pH level of 6-7, which puts them firmly in the neutral-to-alkaline range. This makes them an excellent choice for maintaining good health.

Many fruits are acidic because they contain citric, malic, tartaric, and other acids. Apples, however, are slightly alkaline, meaning they won’t damage your teeth or upset your stomach when eaten.

Why Should You Know if Apples Are Acidic or Not?

Knowing whether apples are acidic or not is essential for a few reasons. For one, it can help you choose healthy snacks that won’t damage your teeth.

Secondly, if you have a sensitive digestive system, eating an alkaline fruit like an apple may help reduce acid reflux and other stomach issues.

What Is In Apples?

The chemical composition of apples is responsible for their low acidity level.

Apples contain malic acid, citric acid, and tartaric acid, but at much lower levels than other fruits such as lemons and oranges.

Apples’ pH level is also higher than these other fruits, resulting in a more alkaline food item.

Combining these acids and other essential vitamins and minerals contributes to apples’ overall low acidity level, making them a safe and healthy snack for everyone to enjoy.

  • Malic acid: 0.06%
  • Citric acid: 0.03%
  • Tartaric acid: 0.02%
  • Phosphoric acid: 0.01%

How Acidic Are Apples?

The low levels of acids in apples do not significantly affect the taste or texture. Apples are still considered to be mildly acidic, but their acidity is much less than other fruits, such as oranges and lemons.

Several scientific studies have examined the acidity levels of apples. According to the findings, apples are more alkaline than acidic, with a pH of around 6-7.

One study even found that apples had a slightly buffering effect on stomach acid and could help reduce symptoms of acid reflux.

This makes them ideal for people with sensitive stomachs who cannot tolerate high-acid foods. Because the acidity level of apples is low, they are also unlikely to damage your teeth when eaten.

Malic Acid vs Citric Acid:

Malic acid and citric acid are the most common acids in apples. Malic acid has a slightly sour flavor, while citric acid is more tart. Both acids contribute to the overall taste of an apple but have little effect on its pH level or acidity.

How to Tell Acidity:

If you want to be sure that an apple is not acidic, there are a few easy ways to check.

  • You can use a pH strip to measure the pH level of the apple—anything below seven is considered acidic, and anything above 7 is alkaline.
  • If an apple tastes sour or tart, it may contain higher acid levels and should be avoided.
  • You can use a taste test—if an apple tastes sweet, it is likely, not acidic.


Apples are not acidic. They have a neutral pH level of 6-7, which makes them slightly alkaline. Apples are also an excellent source of vitamins and minerals that can benefit your health.

Knowing the acidity levels of different foods is essential for maintaining healthy teeth and avoiding stomach issues.

So, next time you’re in the mood for a snack, reach for an apple instead of something sour or tart. You can be sure it won’t damage your teeth or give you any unpleasant digestive issues.
