Are Raspberries Bad for Acid Reflux? [Health Hazards]

Have you ever wondered why raspberries could be considered both healthy and dangerous at the same time? If you have a history of acid reflux or gastritis, then this is a question you probably ask yourself all the time.

Acid reflux is an abnormal condition in which the acidic fluid of the stomach flows backwards into the esophagus and causes heartburn.

Reflux occurs when the muscle at the top of the stomach, called a sphincter, relaxes too much, and allows gastric contents to move up into the esophagus. This causes symptoms.

The more acidic the contents of the stomach, the worse the symptoms tend to be. Very fatty foods also tend to exacerbate heartburn. Any fruits that contain a large amount of acid may exacerbate acid reflux.

For example, raspberries, strawberries, lemons, grapes, and blueberries are some of the more acidic fruits that can cause acid reflux.

Signs of Having Acid Reflux

There are some general symptoms of acid reflux. Having one of these symptoms doesn’t necessarily mean you have acid reflux.

Sometimes, acidic fruits or greasy fast foods cause temporary signs of acid reflux in people who are otherwise healthy, and generally don’t suffer from reflux.

  • Sensation of heartburn, especially after eating acidic or greasy foods
  • Frequent regurgitation of sour liquid or semi-solid food particles. This causes the throat to burn as well.
  • Difficulty swallowing.
  • Bloating, vomiting, bad breath and frequent sour hiccups

How Are Raspberries Causing Acid Reflux?

Raspberries do not exactly cause acid reflux, but since they are acidic, they can exacerbate the symptoms. The stomach is a naturally acidic environment, but eating acidic foods can make it more so.

This doesn’t mean that you can never eat raspberries if you suffer from reflux. Eating them in moderation will likely not harm you in any way.

But, overeating any acidic foods definitely can worsen acid reflux, so they should be eaten in moderation.
