But there’s no harm in having blueberries in small quantities. That’s how you can keep your diet complete, leveled, and healthy without triggering any underlying illness.

Moreover, among all the other fruits, blueberries are actually slightly acidic. Thus people who have issues like acidic reflux wouldn’t need to worry much if there’s a small number of blueberries in their diet chart because all the other health advantages of blueberries adjust their acidic trait.

Also, blueberries are quite a heavy fruit for the appetite. You won’t be able to consume too much of these altogether. Hence, the chances of causing acidic flux are less likely.

Are Blueberries Good for Acid Reflux?

Blueberries are not good if you’re recently suffering from acid reflux. However, blueberries can not trigger acid reflux if you already have no symptoms related to acid reflux or heartburn. In this case, eating a moderate amount of blueberries will not cause acid reflux as blueberries are not highly acidic. They fall in a mild acidic category.

On the other hand, if you’re eating a lot of blueberries and you already have a problem with heartburn or acid reflux, it can worsen your symptoms. Also, if you’re suffering from active gastritis, eating blueberries can be harmful.

In patients with gastritis, there is already an inflammation of the lining of the stomach. Blueberries contain citric acid and ascorbic acid. So, they can irritate the stomach lining.

Next comes, the amount of blueberries you snack on. Although blueberries are mildly acidic, eating a lot of these can stimulate the stomach lining to produce more acid. This can also aggravate acid reflux. Also, the stomach will produce more hydrochloric acid to digest a greater amount of blueberries. This can burn your throat or stomach.

So, eating a moderate amount of blueberries is not harmful to acid reflux. But as you increase their amount, you are most likely to suffer from heartburn.

Also, there are various health benefits of eating blueberries. These benefits include a healthy heart and brain.

So, to enjoy these benefits just limit the consumption of blueberries to avoid acid reflux.

Does Blueberry Juice Deteriorate Acidic Reflux?

Well, if you have acid reflux, then it’s better to avoid blueberry juice specifically. Because Blueberries are somewhat acid-forming. Although blueberry juice has a similar level on pH scale, like fresh blueberries, the juice doesn’t contain the exact amount of fiber that you’ll get from raw blueberries.

This makes the juice inadequate for consuming your gut acid, and this might deteriorate your signs of acid reflux. This is why doctors suggest consuming fresh blueberries instead of blueberry juice.

Also another thing that we overlook most of the time is the number of blueberries we need to use while making the juice. 

It’s actually way more than the amount you usually snack on. It results in high sugar intake and digestion problems. And this can cause heartburn and other issues because your acid reflux can resurface in your esophagus.

If you notice, you would need a huge amount of sugar to make the jam and a lot of blueberries at the same time. You see, raw blueberries are acidic in general but that’s quite moderate. 

However, when you mix these fruits with sugar, these will hamper your digestion, and on top of that, it’ll generate extra acid in your stomach. Nonetheless, it’s mostly noticeable if you buy jams from shops because those are filled with different additives. 

But if you prefer homemade blueberry jam, then the issues mentioned above can be avoided to some extent. Or just try to prepare the jam considering your diet and other health concerns. 

This way there won’t be a bucket of harmful additives or sugar intake, only a jam made fresh and raw blueberries. Always go for the raw blueberries as they’re full of fiber and other beneficial nutrients rather than pesticides and toxic chemicals. Therefore, no more suffering from stomach acidity. 

Are Blueberries Beneficial for Health?

You see, there’s a strong connection between your weight and acidic reflux. If you have excess weight then very low acidic food might trigger your acidity. However, blueberries don’t have many calories. If you want to calculate then it’ll be around only 84 for each cup.

Furthermore, these fruits would help you a lot if you’re dehydrated as they contain about 85% water. Blueberries don’t contain fat as well. Fat can be the trigger for acidic reflux or GERD and sometimes deteriorate the situation.

In short, even though blueberries are slightly acidic, all the other health benefits of this fruit make it beneficial for your health.

To your surprise, the benefits don’t end here. Blueberries are also very rich in many vital vitamins such as vitamin K. Do you know, blueberries are very beneficial in helping blood clotting and therefore, wound recovery?

On top of all these, blueberries are really good for people who have diabetes.

Although a cup of blueberries contains around 15g of sugar, they’re good to neutralize the sugar effect because of their bioactive compounds. Therefore, your blood sugar will be in check, and your insulin and glucose metabolism as well.
