Hydrochloric acid is needed to break down food in the stomach and absorb the nutrients, according to the website Food Scout. This type of acid can also help the body fight off parasites, fungi, and bacteria. A hydrochloric acid deficiency is usually caused by a poor diet consisting of processed carbohydrates, dairy products and sugar. Low hydrochloric acid levels have been associated with some mental and physical conditions, including grey hair, depression, Celiac disease, arthritis, asthma, osteoporosis, ulcerative colitis, and nutrition-deficiency weight-loss. Eating foods that stimulate the production of hydrochloric acid in the stomach can help the body to function at an optimal level.

Apple Cider Vinegar

A food source that is high in hydrochloric acid is apple cider vinegar. The website Aim for Health estimates that one to 10 teaspoons of apple cider vinegar combined with a glass of water can increase hydrochloric acid production in the body. This vinegar mixture can help you rapidly break down any food consumed during a meal. It is important to remember that drinking undiluted apple cider vinegar can burn your throat, so you should always dilute the vinegar with water or add it to a meal before ingesting it. If you experience a burning sensation in your throat while consuming apple cider vinegar, you can counteract its acidity by adding a teaspoon of baking soda to a glass of water or drinking a glass of milk.

Lemon Juice

Lemon juice is rich in vitamin C and can increase the amount of hydrochloric acid in your stomach, according to the website The Analyst. Lemon juice also supports gallbladder function, strengthens the immune system and aids in iron absorption. Drinking lemon juice with a meal can counteract the adverse effects of eating foods with large amounts of acid.

Black Olives

Adding black olives to a meal can help you to increase your body's hydrochloric acid levels, according to the website Food Scout. Black olives stimulate the production of hydrochloric acid in the stomach, which helps the breakdown of foods in the digestive system and absorbs nutrients and vitamins. In addition, black olives contain antioxidants that help fight infections and keep the body functioning optimally.


Celery can increase the amount of hydrochloric acid in your body, according to the website Food Scout. Celery can stimulate bile acid secretion, which can lower cholesterol levels in some people. This vegetable also contains a healthy amount of sodium, which is needed to produce hydrochloric acid. Celery also contains coumarins, which increases white blood cell activity and strengthen the immune system.


Incorporating spinach into your daily diet can increase your hydrochloric acid levels. Spinach is considered a leafy green vegetable that can stimulate hydrochloric acid production in the stomach, according to the website Food Scout. Other leafy green vegetables that can increase hydrochloric acid are kale and barley grasses.
