Plant-Based Diets: Does Corn Fit In?

Corn is a popular food and ingredient, but is it included in a whole-plant-based diet? A whole-plant-based diet includes natural foods that are not heavily processed, and foods that come from plants, excluding animal products like meat, milk, eggs, and honey. Corn is a plant-based food, and it can be part of a whole-plant-based diet as long as it is not heavily processed or combined with animal products. Whole-grain corn, for example, is considered a healthy option within this diet. However, highly processed corn products, such as tortilla chips, corn syrup, and certain types of popcorn, offer fewer health benefits and may not align with the principles of a whole-plant-based diet.

Corn is a whole grain

When purchasing corn products such as corn tortillas, taco shells, or cornmeal, it is important to look for terms like "whole corn" or "whole-grain corn" in the ingredient list to ensure it is a whole grain product. The Whole Grains Council has also created a whole-grain stamp that can be found on many whole-grain products. Additionally, some products may have their own symbol to indicate that they are made from whole grains. Nevertheless, it is always recommended to check the ingredient list to confirm the presence of whole grains and their prominence in the product.

Popcorn, made from the dried kernels of flint corn, can be a nutritious, filling, and healthy whole-grain snack, provided it is not loaded with added fat and sodium. Preparing plain air-popped or microwave popcorn at home is the healthiest option, as pre-packaged and movie theatre popcorn tend to be high in salt and grease.

Corn is a versatile crop with various uses. Corn husks, for example, can be used for cooking tamales or even woven into textiles for shoes and baskets. Corn silk is also dried and used in traditional Chinese and Native American medicine as a tea. Furthermore, corn is a significant crop in the United States, with a large portion of the country being well-suited for its cultivation.

In terms of nutrition, corn is a good source of fibre, both soluble and insoluble. The soluble fibre in corn helps control cholesterol levels, while the insoluble fibre aids in digestion and supports the growth of healthy gut bacteria. Corn is also naturally gluten-free, low in fat, and provides small amounts of protein, sodium, vitamin A, carbohydrates, B vitamins, magnesium, and potassium.

Corn is a starchy vegetable

Corn is a versatile crop with many uses. It can be eaten as a grain or vegetable, and its husks can be used to make tamales or woven into textiles for shoes and baskets. Corn silk is also used in traditional Chinese and Native American medicine as a tea. The entire corn plant has a purpose.

Corn is a good source of many vitamins and minerals. Popcorn tends to be higher in minerals, while sweet corn is higher in vitamins. Corn contains:

• Manganese
• Phosphorus
• Magnesium
• Zinc
• Copper
• Pantothenic acid (vitamin B5)
• Folate (vitamin B9)
• Vitamin B6
• Niacin (vitamin B3)
• Potassium

Corn is also a decent source of protein, with a content range of 10-15%. The most abundant proteins in corn are known as zeins, which account for 44-79% of the total protein content.

In terms of its nutritional value, corn is a low-calorie, low-fat food. A medium ear of sweet corn or a half cup of fresh, frozen, or canned kernels has about 77 to 100 calories and only about one gram of fat. The majority of that gram of fat is polyunsaturated, which can help reduce cholesterol and inflammation.

When it comes to a whole plant-based diet, corn can be included in various forms. Fresh, frozen, or canned corn kernels are all suitable options. Corn tortillas, whole-grain corn, and popcorn are also acceptable. However, it is important to note that highly processed corn products, such as tortilla chips, offer fewer health benefits.

Corn is gluten-free

While corn is gluten-free, it is not a suitable staple food for humans, according to one nutritionist. They argue that corn is difficult for humans to digest, high in calories, and low in nutritional value. Furthermore, corn is the second most commonly genetically modified food, and its genetic modification has been linked to the deaths of animals in scientific studies.

Corn is included in a whole-food, plant-based diet. This type of diet includes natural, unprocessed, or minimally refined foods that come from plants and are free of animal ingredients. Corn is considered a starchy vegetable or a grain and is a staple in many cultures.

Corn is a good source of antioxidants

Corn as a Source of Antioxidants

Corn is a healthy grain and source of fiber, vitamins, minerals, and antioxidants. It may promote eye and digestive health. Whole-grain corn is as healthy as any cereal grain, as it’s rich in fiber and many vitamins, minerals, and antioxidants. Corn contains higher amounts of antioxidants than many other common cereal grains.

Lutein and Zeaxanthin

Corn is particularly high in lutein and zeaxanthin, two carotenoids that may prevent cataracts and age-related macular degeneration (AMD). Lutein and zeaxanthin are the predominant carotenoids in corn, accounting for approximately 70% of the total carotenoid content. However, their levels are generally low in white corn. Lutein and zeaxanthin are only one part of the story when it comes to corn's antioxidant content.

Ferulic Acid

Ferulic acid is one of the main polyphenol antioxidants in corn, which contains higher amounts than other cereal grains like wheat, oats, and rice.

Anthocyanins

This family of antioxidant pigments is responsible for the color of blue, purple, and red corn.

Corn in a Whole Plant-Based Diet

Corn is included in a whole plant-based diet. It is considered both a vegetable and a cereal grain. Sweet corn that you eat off the cob is usually considered a vegetable in the culinary world, whereas the dry seeds that are used for popcorn are classified as whole grains.

A whole-food, plant-based diet is based on the following principles:

• Whole foods: Natural foods that are not heavily processed. That means whole, unrefined, or minimally refined ingredients.
• Plant-based: Food that comes from plants and is free of animal ingredients such as meat, milk, eggs, or honey.

Corn fits into both of these categories, and is therefore included in a whole plant-based diet.

Corn is a source of protein

Corn is also a good source of many vitamins and minerals. One cup of sweet yellow corn, for example, contains about 10% of the daily value of vitamin C, an antioxidant that supports the immune system, collagen production, and iron absorption. It also provides about 20% of the daily value of thiamine and 15% of folate, both of which are B vitamins that help convert carbohydrates into energy.

In addition to its nutritional benefits, corn is naturally gluten-free, making it a safe option for those with celiac disease or gluten intolerance. It is also a versatile crop that can be classified as a grain, vegetable, or starch.

However, it is important to note that corn is relatively high in carbohydrates and contains phytic acid, which can inhibit the absorption of minerals like calcium, magnesium, iron, and zinc. Some people may also have intolerances to corn or be concerned about its potential GMO content.
