 Corn – Health Benefits. High Fiber & Popcorn Power 

Introduction

Corn, a staple crop cherished worldwide, is far more than just a sweet summertime treat or a movie night snack.

Whole-grain corn is a nutritional powerhouse that supports digestion, heart health, and even fights oxidative stress.

Health Benefits of Whole-Grain Corn

Whether you're a health enthusiast, a foodie, or just someone curious about improving their diet, understanding corn's potential can revolutionize the way you think about this humble grain.

What is Whole-Grain Corn?

Examples of whole-grain corn include:

• Popcorn

• Fresh corn kernels (on the cob or off)

• Cornmeal labeled as "whole cornmeal"

Processed corn products like cornflakes, corn syrup, or degermed cornmeal often lose many nutrients during production. That's why eating corn in its whole-grain form is key to reaping its health benefits.

Corn in its natural state is an excellent source of:

Dietary fiber
