As you are supplying your kitchen pantry do not overlook the benefits of whole grains. A nutritional powerhouse, whole grains are an excellent source of dietary fiber, B vitamins, minerals and antioxidants and a number of other health benefits. They are easy to store, economical, simple to prepare, long lasting and make a great investment of your food dollars. 

Examples of whole grains include:

  • Rice
  • Oats
  • Corn
  • Quinoa       (pronounced KEEN-wah)
  • Millets        (Sorghum, Teff, Fonio)
  • Buckwheat
  • Barley
  • Rye
  • Wheat        (Spelt, Emmer, Kamut, Einkorn)

What are Whole Grains?

A whole grain is a seed from a plant that is still completely intact. Containing three parts: Bran, Germ, and Endosperm–these foods remain unprocessed and retain all of their natural components.

All of the foods listed above contain edible seeds with these three components:

Bran: The outer skin. Packed with fiber, B vitamins, and antioxidants.

Germ: The part of the seed that sprouts into a new plant. This part contains healthy fats and vitamin E.

Endosperm: The largest part of the kernel. Mostly starch and carbohydrates.

When grains are refined the bran and germ are removed, leaving only the starch and carbohydrates. While this makes the grain softer and provides a longer shelf life, the vast majority of nutrients are removed. 

Whole grains are a filling, economical source of healthy starch, fiber, and fat and are low in calories. Eating grains as close to their natural form as possible is the healthiest way to add these back into your daily diet. Many foods, such as pasta, crackers, and bread contain whole grains and provide easy ways to get the recommended amount. 

“Bowl Meals” are another excellent way to incorporate whole grains into your everyday diet. Use them as a base, add ingredients and enjoy a compact meal for breakfast, lunch, or dinner. 

Investing in a 25 pound bag of brown rice or other grain is a great way to spend your food dollars. Uncooked rice can be stored in a Zip-Lock style bag in the freezer for 12-18 months or stored in an air-tight container at room temps for 3-6 months. They can be used in a variety of dishes with a multitude of added flavors from fruits and vegetables, plant or animal based protein, and sauces. Whole grains make a great pre-packed lunch or breakfast bowl for the week! 

Whole grains are very easy to cook. They generally require 1 cup of grain to 2 – 3 cups of water. Follow the package’s instructions for the specific product you purchase. They can be stored in the refrigerator for up to five days after cooking.

Whole grains are grown on every continent and are a main staple of many international cuisines. The chart below shows the originating geographical area for common grains.

We can all benefit from incorporating whole grains into our diet. With health benefits including better digestion and nutrient absorption from increased fiber intake, a positive impact on heart health by reducing bad cholesterol, triglycerides, and insulin levels, whole grains are a great option for a healthy breakfast, lunch, dinner or snack.
