Strawberries are one of the greatest sources of dietary fiber, vitamin C, minerals, and antioxidants. But some people with significant heartburn will notice an increase in their symptoms after eating strawberries.

So, we ask ourselves, are strawberries acidic?

Strawberries have a relatively low pH, in the range of 3.0-3.5, which indicates that they are, in fact, acidic. Strawberries are rich in organic acids. They contain ascorbic acid, malic acid, and citric acid. Since they are acidic, they can worsen symptoms of acid reflux if not managed properly.

In today’s article, we will discuss the health benefits as well as the drawbacks of eating strawberries. We will also discuss how to manage a love of strawberries for someone who suffers from acid reflux. So let’s get started.

Why are Strawberries acidic?

Strawberries have a pH range of 3.0-3.5, which definitely qualifies them as acidic. At this point, you may feel confused. If strawberries are so acidic, why do they taste so sweet?

Though strawberries are relatively low in sugar, they are sweeter than any other berries. The reason is the presence of volatile organic compounds.

These compounds have the effect of making strawberries taste sweet. Strawberries contain approximately 30 volatile components, including esters, alcohols, ketones, aldehydes, and others.

Moreover, as they ripen, strawberries lose their acidic content. Unripe strawberries are very acidic, but as they ripen, they become less acidic. Ripe strawberries have a higher pH (meaning they are less acidic), ripe strawberries’ pH ranges from 3.6 to 4.1.

Fun Fact: You may wonder about strawberries having sexes! Yes you heard me right. They have three varieties: female, male and combo. This was discovered by a farmer in 1840 in Ohio.

pH of various strawberry products

Strawberries & By products	pH level of Strawberries
Unripened strawberries	3.0-3.5
Ripened strawberries	3.6-4.1
Strawberry jam	3.0-3.4
Strawberry juice	3.44
Strawberry filling	3.81-5.00

As we can see in the table above, different forms of strawberries have very different levels of acidity. The lower the pH, the more acidic the fruit. These pH ranges will help you select your strawberries wisely according to your individual sensitivity to acidic foods.

Strawberry nutritional analysis

Content of strawberries	Amount (g/100ml)
Glucose	1.89-4.52
Fructose	2.14-4.14
Citric acid	0.73-1.58
Malic acid	0.22-0.69

From this breakdown, we can see that strawberries are composed primarily of sugars and organic acids. The organic acidic compound has the right potential to worsen symptoms of acid reflux.

Strawberries also increase your HDL (High density lipoprotein, or “good cholesterol”), which is good for our health.

They help control blood pressure, provide a good amount of vitamin C, are a great source of dietary fiber, and contain antioxidants that help to grow immunity. There is even a study that claims that they can help your immune system fight cancer.

Strawberries and acid reflux: Good or bad?

While they have lots of health benefits, strawberries can have some bad effects as well. Unfortunately, strawberries can worsen symptoms of acid reflux and can make your stomach quite upset.

Acid reflux occurs when the muscle at the top of the stomach (called a sphincter) relaxes, which allows stomach contents to pass backwards, and up into the esophagus.

The stomach has a very acidic environment because of the presence of hydrochloric acid. This is secreted by the cells lining the stomach, and it aids in digestion. Therefore, when reflux occurs, this very acidic fluid becomes present in the esophagus.

This creates a burning feeling in the esophagus, chest, and sometimes in the mouth. It can also cause vomiting, chest burn, and bloating. If left untreated, it can cause dangerous changes to the lining of the esophagus over time.

That is why when we eat more acidic fruits like strawberries, it can exacerbate the acidic environment in the stomach and predispose a person to reflux symptoms.

Overall, a person with a history of acid reflux may have trouble again after eating strawberries.

Acid reflux or gastritis should be managed because it can lead to more severe problems like ulceration, esophagitis, and even esophageal cancer. It can also worsen asthma.

Now, here you may think, how can I continue to eat my favorite food (strawberries!), but be risk-free? To help with this, we will show you some hacks that will keep you safe from acid reflux.

7 Ways to make strawberries less acidic and healthier

People love strawberries and crave them. However, they are also acidic, so one should be careful eating them, especially if you have a history of reflux symptoms. Here are 7 suggestions.

Strawberries with alkaline foods

Try to eat strawberries in combination with some more alkaline foods, such as bananas, coconut, or papaya. These more alkaline foods will help lessen the acidic effects of strawberries. 

Having milk

Have some milk right after eating strawberries. This will help you reduce the acidity inside the stomach. Milk has a higher pH, in the range of 7.0-9.0. Almond milk is particularly helpful in reducing symptoms of heartburn. 

Drinking water

Drink lots of water after having strawberries. Water will help to diffuse the acidity and make the pH higher inside the stomach.

The more water in the stomach, the more it reduces the acidity. Large water content dilutes the acid and makes the pH higher.

Coconut water

Having some coconut water is another way to help reduce acidity. Coconut water is primarily water (94%) and is also a very good source of potassium. This is helpful because potassium and calcium are the two major components that help reduce acidity.

Yogurt 

Yogurt is another food that can help reduce the acidic environment in the stomach and blunt the effect of eating strawberries. It is also a great source of calcium, potassium, and magnesium, all of which help control the flow of acid inside the stomach.

Fun Fact: “ Did you know, strawberries are actually known as “false fruits?” They are not true fruits, because they do not have seeds on the inside. 

What fruit is low in acid?

Here is a list of 10 fruits that are low in acid.

Heartburn and cravings for strawberries

It’s natural to have cravings for foods as delicious as strawberries. But then we come back to the heartburn issue. We understand that acid reflux is what causes heartburn. How can we solve the heartburn issue?

• Some anti-acidic drugs help to reduce the burn, known as “antacids.”
• Eat a high alkaline food after having the strawberries, such as bananas, milk, papayas, or coconut.

Fun Fact: Strawberries are the only fruit to ripen in the spring.

Are strawberries acidic to the teeth? Do they damage my teeth?

Yes, strawberries are acidic, and acids can damage the enamel on your teeth. However, strawberries also contain maleic acid, which is beneficial in that it is known to whiten your teeth.  However, strawberries should not be used to whiten teeth.

The effect of the acidity on the enamel and sugar, which can lead to cavities, means that strawberries probably do more harm than good for your teeth. It is a good idea to brush, or at least rinse your mouth, after eating sugary or acidic foods.

Are frozen strawberries more acidic? Should I have it or avoid it?

Frozen strawberries are more acidic than fresh ones, and have a pH of 3.0 to 3.3 on average. Freezing temperatures slow the ripening process, letting the strawberries remain more acidic. This low temperature is necessary for storing the strawberries.

Fun facts: There’s another type of strawberries called “purple strawberries” which was created by the seed company Burpee.

FAQs

Can strawberries cause acid reflux?

Ripe strawberries are safe to eat for a person who has acid reflux. For those who don’t know what acid reflux is, it results from a weakened esophageal sphincter that allows the stomach acid to flow up to the esophagus.

Ripe strawberries have lower acidity and are good for those who have severe problems with acid. Unripe strawberries are more acidic.

Are strawberries citrus or acidic?

Strawberries have a fair amount of citric acid, but they are not categorized as citrus fruits. Why is this? We first need to know what citrus means. Citrus is the genus of certain trees with flowering qualities. Strawberries are grown from small plants on the ground, and are thus not citrus plants.

How to reduce the Acidity of Strawberries?

If you suffer from acid reflux disease yet have a serious craving for strawberries, you can still enjoy them in moderation. You can reduce the acidity of strawberries by eating them alongside something alkaline.
