1. Boost the digestion

Corn contains insoluble fibers. It provides bulk and volume to stool. Thus it makes your digestive system better and prevents conditions like constipation. In it, there are some soluble fibers too. According to Oklahoma state university, these soluble fibers get dissolved in water and form a gel. Thus it prevents diarrhea.

2. Improve eye health.

Corn is a good source of lutein and zeaxanthin, two antioxidants that belong to the carotenoid family. Carotenoids are pigments responsible for the red, yellow, and orange colors in many plants. As antioxidants, lutein, and zeaxanthin help protect the eyes from oxidative stress and damage.

These carotenoids are particularly concentrated in the macula, a small area in the center of the retina responsible for sharp, central vision. By reducing oxidative stress in the eyes, lutein and zeaxanthin may help prevent age-related eye diseases, such as cataracts and age-related macular degeneration (AMD), which are primarily caused by oxidative damage.

Including corn in your diet can contribute to overall eye health by providing these essential antioxidants that support and maintain good vision.

A study on a group of 365 adults found that people whose diet includes lutein and zeaxanthin have lower chances of getting eye diseases as compared to those who don’t get enough carotenoids.

That’s why the ophthalmologist suggests that AMD patients get a sufficient amount of corn regularly.

3. Help prevent cancer

Corn acts as a cancer prevention agent. It also has antioxidants in it These prevent the free radicals from accumulating. These free radicals are responsible for cancer. In this way, they protect us from cancer. Research proved that these corns could cause apoptosis of cancer cells.

An animal study proved that the consumption of corn lowers the risk of cancer in mice.

4. Promotes growth

Corn is a nutritious food that contains several essential vitamins and minerals, which contribute to overall health and well-being. It is a source of vitamin B, niacin, and thiamine, which play crucial roles in promoting growth.

Thiamine is beneficial for nerve health, while niacin helps prevent conditions such as dementia and dermatitis. Additionally, corn is rich in folic acid, making it a valuable food choice for pregnant women, as it supports fetal development.

Corn also contains vitamin E, which acts as an antioxidant, protecting the body from damage caused by free radicals and promoting overall health. 


5. Prevents anemia

Iron deficiency or anemia is a common health issue, particularly in women. Corn is a good source of iron, which is essential for the production of red blood cells. Red blood cells transport oxygen throughout the body, and a lack of these cells can lead to anemia. By consuming corn, individuals can prevent or alleviate anemia symptoms such as fatigue, restlessness, dizziness, and weakness.

However, it is important to note that while corn is a good source of iron, it may not be sufficient on its own to fully address anemia. It is recommended to consume a balanced diet with a variety of iron-rich foods and to speak with a healthcare professional for proper diagnosis and treatment of anemia.

Yes, it is true that corn contains phytic acid, also known as phytate. Phytic acid can bind to certain minerals, such as iron, zinc, and calcium, and reduce their bioavailability for absorption in the body. This can lead to nutrient deficiencies and health complications over time.

However, it is important to note that the negative impact of phytic acid on nutrient absorption is generally minimal and is unlikely to cause significant health issues in individuals with a balanced and varied diet.

Furthermore, cooking methods, such as soaking or fermenting, can reduce the phytic acid content of corn and increase the bioavailability of nutrients. Eating corn in moderation as part of a balanced diet is recommended for optimal health.

2. Mycotoxins

Corn can be susceptible to fungal growth, and some fungi may produce mycotoxins that can be harmful to human health. Mycotoxins consumption has been linked to various health issues, including cancer and neural tube defects.

Proper storage and handling of grains are vital to minimize mycotoxin contamination risks. Ensuring that products like cornmeal and corn flour come from a reliable source and undergo appropriate processing can also reduce mycotoxin levels.

Individuals with celiac disease cannot eat these grains without experiencing an allergic reaction, which can cause damage to the small intestine and other health problems.

4. Pellagra

A diet that predominantly consists of corn, particularly when not treated with alkali (a process called nixtamalization), and lacks other sources of niacin and tryptophan can increase the risk of developing pellagra. This condition was more prevalent historically in regions where corn was a dietary staple and other niacin-rich foods was scarce.

To prevent pellagra and other nutritional deficiencies, it is important to maintain a balanced diet with a variety of foods, including those rich in niacin and tryptophan, such as soy, legumes, nuts, sunflower seeds, pumpkin seeds, and whole grains.


Organic corn is a rich source of various plant compounds, fiber, and nutrients that offer numerous health benefits. It may improve vision, aid in skin health, promote growth, aid in digestion, and prevent anemia.

However, due to its high starch content, excessive consumption may increase blood sugar levels. Therefore, it is essential to consume this vegetable in moderation and stick to the recommended daily serving size.
