Did you know that cucumbers are one of the most beneficial vegetables you can eat, and that they can improve your skin, hair, and overall health? Want to know more? Then this article is for you.

Many people have the misconception that cucumbers are acidic, and that this can be harmful for those with acid reflux. But what do you think? Are cucumbers acidic?

Cucumbers have a pH in the range of 5.1 to 5.7. Despite being slightly acidic, cucumbers do not  have a significant acidic effect within the body. Because of their alkalizing effects upon digestion, cucumbers are classified as an alkaline food. Cucumbers’ acidity varies with how they’re prepared for consumption.

In this article we are going to show you everything you need to know about cucumbers and their effects on acid reflux.

Are cucumbers acidic or alkaline? Question answered!

You may have wondered often whether cucumbers are acidic or not. Let us now talk about it in a detailed manner.

Cucumbers are not directly acidic. That means they are less acidic and closer to neutral. Because of this, eating cucumbers in moderation should not cause any gastrointestinal distress.


Acidic pH but alkaline in nature!

The cucumber has an acidic pH of 5.1 to 5.7 but very interestingly, it is categorized as an alkaline food. One of the biggest reasons for this is their water content.

The high water content is one factor, but you may be wondering what else makes them alkaline. The high levels of potassium in cucumbers are well-known.

Having an alkaline pH, potassium is a very useful element. Cucumbers, then, are among the alkalizing foods.

On their own, the effect on the body is alkalinizing, and they are safe to eat, as long as they are not served with anything acidic like marinades or dressings made with vinegar.

Various pH on variety of Cucumbers

The pH level of cucumbers usually is in the range from 5.1-5.7. Of note, this range can vary from one variety of cucumber to another.  Now let us see how much cucumbers can vary according to their variety.

VarietypH Level
Cucumbers5.12 – 5.78
Cucumbers, Dill pickles3.20 – 3.70
Cucumbers, pickled4.20 – 4.60
Curry Paste, acidified4.60 – 4.80
pH Level of Various Cucumbers

In the above table, you can see the pH values of different forms of cucumbers. Cucumbers are turned into pickles by soaking them in vinegar.

Since vinegar is acidic, the pickling process decreases the pH of cucumbers significantly, making them acidic.

The most acidic form of cucumbers is the dill pickle, with a pH of 3.2 to 3.7. These more acidic versions of cucumbers would not be the best options for patients suffering from acid reflux.

Cucumbers for Acid Reflux: Good or bad?

As we have mentioned above, cucumbers are an alkaline food. What do you think now? Are cucumbers harmful for acid reflux?

Are they bad for acid reflux?

The answer is that no, they are not. Raw cucumbers have a slightly acidic pH, but due to the water content, and presence of certain minerals, they have an alkalizing effect in the body.

When stomach acid refluxes, or rises up into the esophagus, the result is a condition known as acid reflux. In this case, the acid from the stomach flows backwards into the esophagus, causing irritation.

Patients who suffer from acid reflux typically describe their symptoms as heartburn, a painful burning sensation in the center of the chest.

Foods high in acidity are a major contributor to acid reflux. Foods that have a pH of 4.6 or lower are referred to as acidic by the FDA, and warrant particular caution in those with acid reflux.

How Does Cucumber Trigger Acidity?

As Cucumbers are alkaline, they do not trigger acid reflux. Consequently, cucumbers do not contribute to GERD. However, if eaten with acidic or spicy foods – this combination may then worsen reflux symptoms.

Salads with tomatoes, onions, or hot peppers should be avoided if you suffer from acid reflux, GERD, or heartburn.

Cucumbers help in digestion!

Water and fiber, both of which are crucial to proper digestion, are abundant in cucumbers. Adequate water intake as well as adequate fiber intake can both lessen the symptoms of gastroesophageal reflux.

5 Reasons to Start Eating Cucumbers!

I hope you now know that cucumbers are very nutritious for your health and have benefits for your skin, stomach, and heart. They provide so many benefits to your body because of their alkalizing effects.

Cucumbers benefits

Without further delay, let us now go deeper to the reasons why you should love them.

Skin health

Dark circles, swelling, sunburn, and under-eye puffiness are just some of the skin conditions that cucumbers can help alleviate. Cucumbers’ primary compounds, caffeic acid and ascorbic acid, aid in the prevention of water retention.

Improve tissue health

Simultaneously cooling and refreshing, cucumbers are rich in the mineral silica. It’s a lovely mineral, and it plays a crucial role in maintaining the health of your connective tissues. Connective tissues include cartilage, ligaments, tendons, and bone. Healthy connective tissues are essential to overall good health.

Prevention of stomach aches

As far as vegetables go, cucumbers have a relatively high amount of fiber. Cucumber is a great choice for those who suffer from gastroesophageal reflux disease (GERD) because its high fiber content helps prevent stomach problems, and promotes gastric motility, helping to move food along the intestinal tract.

This reduces the chance of stomach contents refluxing, or going “backwards”, in the wrong direction.

Aid for weight loss

Cucumbers are fantastic for dieters because they are 96 percent water, and they contain no fat, cholesterol, or sodium. Cucumbers are a low-calorie food, with low caloric density, so you can eat more of them without consuming too many calories.

Cucumbers, whether added to a salad or eaten alone, can help jumpstart weight loss when combined with other weight loss-friendly foods like lemon juice, black pepper, and salt.

Boosts cardiovascular health

In addition to protecting against cardiovascular disease, the lignans found in cucumbers can also help strengthen the immune system. Cucumbers’ magnesium and potassium content make them an excellent food for maintaining healthy blood pressure.

In addition, they help regulate nerve function, heart rate, fluid balance, blood sugar, and glucose metabolism, and increase energy expenditure.

Does eating cucumbers make you fart?

Yes, they can make you go through some unforeseen situations. It depends  a lot on how they are consumed.  There are a few reasons why cucumbers might increase gas. 

Cucurbitacin can be found in cucumbers and squash which has the capability to make good amounts of gas and can make you gassy easily. You’re more likely to experience bloating or passing gas due to over consumption of cucumbers.


Is cucumber an acidic food?

No, they are not referred to as acidic foods. Though they have a pH of 5.1-5.7 which is slightly acidic, the alkalizing effects of cucumbers can be beneficial, especially in those whose diets have become excessively acidic as a result of poor nutrition.

Is cucumber OK for acid reflux?

Yes, they are. They can also be used to treat acid reflux. Water and fiber, both of which are crucial to proper digestion, are abundant in cucumbers. It is common knowledge that increasing the stomach’s pH by ingesting water can alleviate the acute symptoms of acid reflux.

Why do cucumbers cause heartburn?

In most cases, they do not cause heartburn. But exceptions may be seen in some situations. When you eat cucumbers with any acidic food like salad or tomatoes, you might experience acid reflux. This might result in heartburn in your stomach.

However, this is more likely due to the foods consumed with the cucumbers, not the cucumbers themselves.

Are Pickles acidic or alkaline?

Wait a minute! We know that pickles are made of cucumbers. So, do you think these are acidic? Basically, that depends on how they were pickled.

Pickles purchased from a grocery store are likely to have a high vinegar and additive content, both of which can aggravate acid reflux and GERD symptoms and cause severe heartburn. Therefore, those with a low tolerance for sour or pickled flavors should avoid them.

However, naturally fermented pickled cucumbers are excellent for the flora in your digestive tract. Moreover, their juice is reportedly effective for some people with acid reflux.


In the end, we have all the answers for “are cucumbers acidic?” To put it simply, we can say that cucumbers are slightly acidic, but have predominantly alkaline properties. You can eat cucumbers without worrying about the effect on acid reflux.

But remember, like with any food, there can be too much of a good thing. Most foods are best eaten in moderation!
