What are whole grains?

First of all, there are two types of grains:

  • Whole grains
  • Refined grains

Whole grains are a healthy type of grains because their fiber content is not lost during the milling process. They are called “Whole” because they contain all three parts, the bran, germ, and endosperm.

Refined grains lose their bran part in the milling process and they do not have enough fiber as whole grains. All the beneficial components are lost due to processing.

Fiber lowers the amount of bad cholesterol in the heart and prevents atherosclerosis. They also lower the production of bile acids which are involved in fatty acid storage in the body.
