What’s So Great About Whole Grains?

“Best and Worst Choices.” 

——-

Grains are an important component of most people’s diets. All grains begin as “whole grains,” but processing often alters grain products, resulting in foods that don’t pack the nutritional punch they once did.

Whole grains consist of three key edible parts, says The Whole Grains Council. This includes the bran, germ and endosperm. The bran is the multi-layered outer skin of the edible grain kernel. The germ is the embryo, which can sprout into a new plant. The endosperm is the food and energy source for the germ. The endosperm is the largest component of the grain kernel and has starchy carbohydrates, proteins and small amounts of minerals and vitamins. Conversely, the bran has fiber and B vitamins, while the germ contains healthy fats, protein, many B vitamins, and minerals.

During the refining process, typically the bran and germ are stripped away. That greatly reduces the nutrient profile of the kernel, removing protein and essential nutrients. Some may be restored by enriching refined grains, but refined products can’t compete with the healthy wholesomeness of whole grains.

Whole grains are preferential for a variety of reasons:

· Whole grains contain fiber, which is known to help control blood sugar, lower LDL cholesterol and reduce colon cancer risk. Oats, bulgar and barley have the most fiber.

· Lactic acid, which promotes good bacteria in the large intestines, can be found in whole grains. These bacteria can improve digestion and promote better nutrient absorption, advises Health magazine.

· Whole grains may help a person feel fuller. That can cut down on overeating and help control weight.

· Health experts say that eating whole grains can leave a person with less belly fat, also known as “central adiposity.” This is important for reducing risk of diabetes and other health issues.

These are just some of the reasons to select whole grains over refined, processed ones. Whole grains should provide the majority of grains in a person’s diet.

Best whole-grain bread options:

• 100% Whole Wheat Bread
  Look for “100% whole wheat” as the first ingredient. It provides fiber that supports digestion, heart health, and blood-sugar control.
• Sprouted Grain Bread (such as Ezekiel-style breads)
  Made from sprouted whole grains and legumes, these breads often have higher protein, more bioavailable nutrients, and a lower glycemic impact, according to Harvard T.H. Chan School of Public Health.
• Whole Grain Multigrain Bread
  When all grains listed are whole (not refined), multigrain breads offer a broader range of nutrients and antioxidants.
• Whole Rye Bread
  Rye is rich in fiber and may help improve blood-sugar control and satiety, according to research cited by the American Heart Association.

What to avoid:

• “Wheat bread” that isn’t whole wheat — many are made with refined flour.
• Breads with added sugars, high-fructose corn syrup, or long ingredient lists.
• Very low-fiber breads (less than 3 grams of fiber per slice).

What to look for on the label:

• The words “100% whole grain” or “100% whole wheat”
• At least 3–5 grams of fiber per slice
• Short, recognizable ingredient lists

Bottom line:

Whole-grain breads—especially 100% whole wheat, sprouted grain, and whole rye—are the healthiest options and are consistently linked to better heart health and metabolic outcomes, according to the American Heart Association and Harvard Health Publishing.
