What are the Dietary Guidelines for Americans recommend consuming servings of whole grains per day?

2 min read

Over 80% of Americans do not meet the recommended daily intake of whole grains, despite the well-documented health benefits. So, what are the Dietary Guidelines for Americans recommend consuming servings of whole grains per day to improve these statistics?

Quick Summary

The Dietary Guidelines for Americans recommend making at least half of your total grain intake whole grains. For a 2,000-calorie diet, this translates to at least three ounce-equivalents of whole grains daily. This article explains the recommendations and offers practical tips.

Key Points

  • Daily Recommendation: The Dietary Guidelines for Americans recommend that at least half of your daily grain intake should be whole grains.

  • Ounce-Equivalent: For a 2,000-calorie diet, this equates to a minimum of 3 ounce-equivalents of whole grains per day.

  • Health Benefits: Whole grains lower the risk of heart disease, stroke, type 2 diabetes, and certain cancers.

  • Nutrient Rich: They provide essential nutrients like fiber, B vitamins, iron, and magnesium, which are largely removed from refined grains.

  • Smart Swaps: Easy ways to increase intake include swapping white rice for brown rice or choosing whole wheat bread and pasta.

  • Shopping Made Easy: Look for the Whole Grain Stamp or confirm 'whole grain' is the first ingredient on product labels to make informed choices.

The Dietary Guidelines for Americans (DGAs), including the most recent edition, emphasize the importance of shifting from refined grains to whole grains for optimal health outcomes. For the average healthy American adult following a 2,000-calorie diet, the recommendation is to consume 6 ounce-equivalents of grains daily, with at least half, or 3 ounce-equivalents, coming from whole grains. The guidelines suggest consuming even more whole grains is beneficial.

Understanding Ounce-Equivalents

An ounce-equivalent is a standard measure used by the DGAs. An ounce-equivalent of whole grains is typically the amount of food containing 16 grams of whole-grain ingredients. Examples of one ounce-equivalent include one slice of 100% whole-grain bread or a half-cup of cooked brown rice.

Why Whole Grains Matter for Your Health

Whole grains, containing the bran, germ, and endosperm, offer significant health benefits due to their nutrient content. The fiber in whole grains can help lower blood cholesterol, reducing heart disease and stroke risk. Higher intake is linked to reduced cardiovascular disease mortality. Fiber in whole grains also aids digestion, prevents constipation, and promotes fullness, assisting weight management. Whole grain consumption is linked to lower risks of type 2 diabetes and certain cancers. They are also rich in B vitamins, iron, magnesium, and selenium.

Whole Grains vs. Refined Grains

Refined grains lack the bran and germ, removing vital nutrients.

Feature Whole Grains Refined Grains
Processing Minimally processed; retains all parts. Heavily processed; bran and germ removed.
Nutrients Rich in fiber, B vitamins, antioxidants, minerals. Lower in fiber; some nutrients added back (enriched).
Examples Brown rice, whole wheat flour, oatmeal, barley, quinoa. White rice, white flour, white pasta, many commercial cereals.
Health Impact Lower risk of chronic diseases, better digestive health. Can cause blood sugar spikes; associated with higher risk of some chronic illnesses.

Practical Tips for Increasing Whole Grain Intake

Increasing whole grain intake can be achieved through simple changes. Choose whole wheat over white versions of bread, pasta, and rice. Incorporate quinoa, barley, or bulgur into meals. Start the day with whole grains like oatmeal or whole-grain cereal. Look for the Whole Grain Stamp to identify products with significant whole grain content; the 100% stamp guarantees an ounce-equivalent per serving. Include whole-grain snacks like popcorn. If new to whole grains, mix half whole grain with half refined initially. For more guidance, visit {Link: MyPlate.gov https://www.myplate.gov/myplate-plan}.

Conclusion

The Dietary Guidelines for Americans recommend at least 3 ounce-equivalents of whole grains daily. Understanding ounce-equivalents and the health benefits, and making simple substitutions can help achieve this goal. Prioritizing whole grains supports cardiovascular health, digestion, and reduces chronic disease risk.

Frequently Asked Questions

The Dietary Guidelines recommend that the average adult consuming a 2,000-calorie diet consume a total of 6 ounce-equivalents of grains per day.

An ounce-equivalent is a standard measure for grains. For whole grains, it corresponds to the amount of food that contains 16 grams of whole-grain ingredients. Examples include one slice of whole-grain bread or a half-cup of cooked brown rice.

You can identify whole-grain products by checking the ingredient list; 'whole grain' should be the first ingredient listed. Additionally, look for the Whole Grain Stamp on the packaging, which indicates a minimum amount of whole grains per serving.

Whole grains contain the entire grain kernel—the bran, germ, and endosperm—which retains fiber and essential nutrients. Refined grains have the bran and germ removed, stripping away much of this nutritional value.

Yes, many whole grains are naturally gluten-free. Examples include quinoa, brown rice, millet, buckwheat, and sorghum.

You can add more whole grains by making simple swaps, such as using whole wheat pasta instead of white, eating oatmeal for breakfast, or using brown rice in your meals. Using whole-grain bread for sandwiches is another simple change.

Not consuming enough whole grains, particularly when consuming a lot of refined grains, is associated with an increased risk of heart disease, type 2 diabetes, obesity, and poorer digestive health.
