If heartburn is haunting you every day, you are probably consuming a lot of acidic foods. These foods increase the acid levels in your stomach and put a strain on your gut. So, what is the way out?
Well, you simply need to cut down on certain foods and go for healthier options. Wondering what they are?
In this article, we understand what actually happens when you consume acidic foods, provide you with a list of foods that you should avoid, and suggest some substitutes. Keep reading to learn more!

What Are Acidic Foods?
Foods that have a pH level of 4.5 or lesser and tend to cause more acidity in your stomach are acidic foods. They may taste anything from sour, tart, tangy, citrusy, and vinegary, to sharp, acrid, and even biting and zesty. Some acidic foods may even give out a strong and pungent smell.
To make it simple, let’s understand the concept of acids and bases. All foods – solids and liquids – have a pH value that makes them acidic or basic.
Chemically speaking, the pH value of a compound tells you how many hydrogen molecules it has. On a scale of 1 to 14, all the compounds having a pH less than 7 are acidic. Water is neutral and has a pH of 7. All those compounds above 7 are alkaline or basic foods.
To summarize, lower the pH, higher the acidity. And what foods fall into the low pH, highly acidic category? Here you go…
Top Acidic Foods You Should Stay Away From
Contrary to popular belief, many vegetables and fruits trigger higher acid production and give you acidity.
Let’s look at the list of foods with their pH values that you should not be consuming if you have GERD(gastroesophageal reflux disease) because they decrease the pH of your gut.
|Fruits & Veggies||Meat||Dairy Products|
|Lime (2.0)||Sausages (3.3)||Buttermilk (4.4)|
|Cranberry juice (2.5)||Shellfish (3.3)||Cheese (4.5)|

|Corn syrup (3.8)|
So what if these foods are acidic? Why should you stay away from them? These are some questions you might be asking. I’m coming to that. Read on!
What Happens When You Eat Acidic Foods?
Everything that you eat has to come in contact with the gastric juice in your stomach. This gastric juice is highly acidic and has a pH between 1.5 to 3.5 (equivalent to hydrochloric acid).
Our body has mechanisms to strictly control the pH in the gut and levels of gastric juice in the stomach. When the pH of your stomach is already acidic, and you eat acidic foods, a cumulative effect is created that lowers the pH in your gut even more.
It’s like adding fuel to the fire!
There’s too much acid generated at once, which can give rise to conditions like:
1. Gastroesophageal Reflux Disease (GERD)
Consuming highly acidic foods can damage the protective inner lining of your stomach, giving you dreadful ulcers and terrible acid reflux.
What’s worse is if this acid reflux and inflammation continue and reach the upper GI tract and esophagus, which do not have a protective mucus-secreting cell lining (like your stomach). It can lead to chronic burning sensation, dyspepsiai XUpper abdominal irritation also referred to as indigestion, characterized by bloating, heartburn, nausea, or acid reflux. , acidity, heartburn, and ulcers in your mouth.
This is what happens when you have GERD. Trust me, you will not be able to swallow something as soothing as cold milk!
A study conducted on 2,002 participants found the prevalence rate of typical GERD symptoms that appeared monthly or weekly at 16.5% and 6.8% respectively. It was further observed that two-thirds (209/330) of the patients reported having typical GERD symptoms at least once a month.
2. Causes Tooth Decay
Eating or drinking sugary and starchy foods can lead to the formation of a thin, sticky, invisible film of bacteria called plaque all over your teeth.
When high sugar foods come in contact with plaque, the acids that digest the food attack your teeth till almost 20 minutes after you finish eating.
Repeated acid attacks like these break down the hard enamel layer on your teeth, ultimately leading to tooth decay. Something similar happens in the case of acid reflux too (1).
3. Can Give Rise To Bone Diseases
Due to the Western diets that have a high acid, sodium, and bicarbonate content, and low potassium and calcium content, there is a gradual loss of bone density.
The urinary loss of calcium (which increases by 74% when on highly acidic foods), an inadequacy of potassium and vitamin D, and hypertensioni XHigh blood pressure — a serious medical condition that significantly increases the risks of mainly heart, brain, and kidney diseases. together trigger bone resorption and early onset of bone diseases like osteoporosisi XA bone disorder that arises when bone composition or structure alters or bone mass and bone mineral density decline. (2).
4. Could Cause Kidney Stones
The excretion of minerals like calcium, potassium, and magnesium through urine is essential for your kidneys’ health.
Having highly acidic foods can cause your kidneys to retain a fraction of these minerals while generating urine.
Over time, such mineral deposits turn into renal calculi or kidney stones. These could be fatal if left untreated.
So, how do we stop all this?
A simple way out is to reduce the consumption of such high acid-generating foods. But almost half of the foods we take in daily fall under this category. Some of them are highly nutritious too!
Then, how do we make it up?
The good news is that we have many substitutes for these foods that are equally nutritious but less acidic. You can try to choose the more alkaline options to prevent acid reflux.

Substitutes For Acidic Foods
Choosing less acidic or alkaline foods over highly acidic ones can prevent you from burning your gut and esophagus.
