Introduction

Corn is one of the most popular and widely consumed crops in the world. Not only is it a major staple food in many countries, but it is also used to make a range of products from fuel to animal feed. But despite its ubiquity, humans are unable to digest corn in its natural form. In this blog post, we will explore why humans cannot digest corn and what the implications of this are for our health. 

Why can't humans digest corn?

The Digestive System

The digestive system is the process by which food is broken down and absorbed by the body. In order for humans to be able to digest and absorb food, the food needs to be broken down into small enough particles that can be absorbed by the small intestine. This process is known as digestion. 

The digestive system is made up of several organs, including the stomach, the small intestine, the large intestine, and the pancreas. The stomach is responsible for breaking down food and releasing digestive enzymes that help break down the food further. The small intestine is where most of the digestion and absorption of nutrients take place. The large intestine is responsible for absorbing water and electrolytes, and for storing waste. The pancreas produces hormones such as insulin and glucagon, which help regulate blood sugar levels. 

Why Humans Can’t Digest Corn?

Corn is a complex carbohydrate, meaning it is made up of long chains of sugar molecules. Humans lack the enzymes to break down these long chains into smaller molecules, so the corn is not digested in the stomach. The small intestine is also unable to digest the corn, as it does not have the enzymes to break down the long chains of sugar molecules. As a result, the corn passes through the digestive system without being digested or absorbed. 

The Implications of Not Being Able to Digest Corn

The inability to digest corn can have serious implications for human health. When corn passes through the digestive system without being digested, it can cause a range of digestive issues such as bloating, gas, and abdominal pain. Additionally, because the corn is not being digested and absorbed, it can cause an imbalance in the gut microbiome, leading to further digestive issues. 

The undigested corn can also interfere with the absorption of other nutrients, such as vitamins and minerals. This can lead to deficiencies in essential nutrients, which can have a negative impact on overall health. 

Cooking Corn

One way to make corn more digestible is to cook it. Cooking breaks down the long chains of sugar molecules, making them easier to digest. Additionally, cooking can make the corn more palatable and easier to digest. 

Fermenting Corn

Fermenting corn is another way to make it more digestible. Fermenting corn involves exposing it to beneficial bacteria, which helps break down the long chains of sugar molecules. This makes the corn easier to digest and can also make it more nutritious, as the fermentation process can increase the availability of certain vitamins and minerals. 

Conclusion

Humans are unable to digest corn in its natural form due to the long chains of sugar molecules that make up its complex carbohydrate structure. This can have serious implications for human health, as undigested corn can interfere with the absorption of other nutrients, leading to deficiencies. However, there are ways to make corn more digestible, such as cooking and fermenting it. By doing so, the corn can be made more palatable and easier to digest, as well as more nutritious.
