Is Corn Acidic? (How Bad Is It?)

Most vegetables and fruits produce an alkaline effect in your stomach after eating. Still, some certain vegetables and fruits are acidic by nature, like lentils, olives, blueberries, glazed or canned fruits.

In this write-up, we are going to discuss if corn is acidic.  

Is Corn Acidic?

Corn is indeed acidic by nature. The pH of different forms of corn, including corn on the cob, corn flakes, and canned corn, varies between 5.9 and 6.2, which shows it is acidic by nature. Products with pH less than 7 are considered acidic, whereas pH more than 7 is alkaline or basic by nature.

How to recognize acidic foods? 

Certain foods contain FODMAPs, rapidly fermentable carbohydrates, which can cause gas, gut inflammation, uncomfortable tummy, and bloating in some people because they can feed bacteria.

But some of the foods with FODMAPs can also help eliminate GI problems and improve your digestion.

According to experts, a diet with a high level of fiber-rich foods can improve the growth of healthy bacteria in your gut as it can help in controlling inflammation in your stomach.

Though corn is acidic, it can still be good for your stomach if consumed moderately. Corn is consumed in various forms like cooked on the cob, popcorn, and maize flour used for making cornmeal.

It is challenging for some people to digest fresh sweet corn as it has 2 types of FODMAPs.

Popcorn is considered a healthy and light snack, but it can upset your digestion due to the high density of carbs in it, as in 100 grams of fresh sweet corn, there are nearly 64 grams of carbs. Most people can easily digest some of the corn-related preparations like corn tortillas and whole cornmeal etc.

The preparations made by using whole grain maize flour can also be digested easily due to the low level of FODMAPs in it. So, to find the most suitable corn preparation for your belly, you must try out some of them. But to digest corn products easily, you should consume them in limited quantities.

Animal proteins and red meat: Processed meat and red meat are the most popular acid-producing foods in the western diet. Eggs and chicken are the other animal proteins that are high in acidic nature.
