Potatoes are good for gastritis: What is the evidence?

Potatoes are potentially good food for gastritis. Potatoes are mildly acidic (Its PH is between 5.4-5.9) (reference). Foods that can hurt your gastritis are often below the pH level of 4.6)

So, Potatoes don’t increase your stomach acidity, and it is not considered a trigger for gastritis (unless eaten in high quantities).

Potatoes reduce the inflammation of the stomach lining.

Potatoes have anti-oxidant and protective effects against gastritis. In addition, one study found that Potatoes contain a compound called (Potato peptides or Po-P).

The Potato peptides (Po-P) acts as anti-oxidants. Anti-oxidant compounds help protect your body cells from damage, inflammation, and cancer transformation.

Research successfully isolated the Po-P from potatoes and administered it to rats with gastritis. Po-P compounds in potatoes reduced gastritis dramatically (reference).

The researcher concludes that potatoes can be good food for gastritis.

 

Potatoes may improve gastritis by reducing acid production.

Potatoes contain a group of sugar compounds called (Potato Galactan Polysaccharide (PGP)). The research found that Potato Galactan Polysaccharide (PGP) can inhibit stomach acid secretion (reference).

The anti-acid effect of potatoes works similarly to some famous stomach ulcer drugs called (proton pump inhibitors or PPIs). The most famous drugs are Nexium (Esomeprazole) and Prilosec (Omeprazole).

The PGP in potatoes inhibits an enzyme called H+, K+-ATPase. The inhibition of this enzyme will reduce the amount of acid secreted into your stomach and improve gastritis.

However, The researcher isolated the substance (PGP), and the results were only experimental (done on rats with gastritis). Thus, we currently don’t know if potatoes retain these anti-acid effects when consumed by humans or not.

Also, we don’t know the effects of the processing and cooking of potatoes on such compounds. More research is needed.

Can Potatoes Kill H. pylori?

Many fruits and vegetables showed anti-h. Pylori activity in experimental studies. Scientists think the anti-h. Pylori properties of fruits and are due to their content of phenolic derivatives (reference).

Dr. Chatterjee and his research team found that phenolic compounds in the (berry) family of fruits can fight clarithromycin-resistant h. pylori strains (reference).

Potatoes are vegetables that contain Phenolic derivatives, which is a possible good for H. pylori-induced gastritis.

Main sources:

  • Highbush blueberry (and its extract).
  • Strawberry, raspberry, blackberry, and bilberry.
  • Other fruits such as apples, peaches, apricots, plums, cherries, pears, and grapes.
  • Vegetables such as yellow onion (highest source), potatoes, rhubarb, red cabbage, etc.
  • Some grains such as buckwheat, rye, oats, and barley.
  • Beverages such as cider, coffee, soy milk, regular milk, black and green tea.

NOTE: some of the phenol-containing foods are irritant to your stomach. Some foods can do more harm than good to gastritis. So, Consult your nutritionist or your doctor before you eat any trigger food. Fortunately, Potatoes are not considered a trigger for gastritis.

Raw potatoes vs. cooked potatoes for gastritis.

The cooking and processing of potatoes can reduce their anti-oxidative effects. For example, one study showed that cooking might decrease the activity of phenolic compounds inside potatoes (reference).

However, eating raw potatoes can also cause some digestive issues due to the high starch compounds of potatoes.

The key here is to experiment and to work with your dietitian. Potatoes are not a magic food that health gastritis. However, it is at least not a trigger if consumed in moderation.

Can Potatoes trigger gastritis?

Although we lack sufficient evidence that potatoes can heal gastritis, the thing we are sure about is that potatoes don’t cause gastritis.

Potatoes are not a trigger for gastritis. But you should note that potato additives such as butter species can trigger your gastritis. Be aware of the contents of your potato meal to avoid worsening your gastritis,
