General Whole Wheat Facts and Statistics

Highly nutritious, fiber-rich whole wheat foods have been a healthy diet staple for a long time due to their ability to lower the risk of many health conditions such as stroke.

Let’s go through some of the essential whole wheat grain nutrition facts and find out what they are and what makes them so beneficial.

1. Whole grains have all three parts of the grain intact.

(Healthline)

Either in their usual or ground form, whole grains consist of the bran (outer layer), germ (embryo), and endosperm (food supply).

Their refined counterparts usually retain less of the nutrients in comparison to whole-grain foods.

2. Whole wheat and whole oats are among the most popular options.

(GoodHouseKeeping)

Other sources include brown rice, whole rye, freekeh, whole-grain barley, buckwheat, bulgur, quinoa, and corn.

3. Whole wheat and whole-grain products differ in terms of ingredients.

(Healthline)

The difference between whole-grain and whole wheat products is the type of grain used during production.

Whole wheat products contain the entire wheat kernels only. On the other hand, whole-grain products also include other types of whole-grain (e.g., corn, millet, barley, sorghum, quinoa, rye, etc.).

4. Whole grains are mostly used for preparing different foods.

(Food Insight)

A wide variety of whole-grain bread, pasta, and other food items are made with whole grains. Foods made with these grains are held as more nutrient-dense than the refined alternatives since they tend to have more trace minerals, vitamins, and fiber.

Whole grains also have additional phytochemicals that are believed to help reduce the risk of diseases.

Whole-Grain Products: Statistics and Facts

Whole-grain products, ranging from whole-grain pasta to whole wheat flour, are highly nutritious. They’re packed with different minerals such as copper, zinc, and iron that give them various health-maintaining properties.

5. The whole-grain pasta market in Italy is huge, with an accumulated sales value of around 21,4 million euros in 2018 only.

(Statista)

When looking at the entire organic whole-grain pasta market by type, there are three primary sources (whole-grain, spelt, kamut).

The first type had the most sales in 2018. However, spelt could accumulate approximately 8.6 million euros, while kamut managed to generate a sales value of a little over 9 million euros.

6. The whole-grain industry is growing, with around 13,000 different products carrying the Whole Grain Stamp in May 2021.

(WholeGrainsCouncil)

According to the Whole Grains Council’s latest statistics, the products are available in 63 countries, and around 28% of them are sold outside the US market.

7. In 2018, the demand for whole-grain pasta in Italy grew by 12%.

(Ansa)

The Italian whole-grain market was also forecasted to see an additional 18% increase in the demand for whole wheat pasta in the forthcoming years, according to expert accounts in Dubai at the 20th World Pasta Day, an event organized by the International Pasta Organization.

8. Whole wheat flour is more susceptible to spoilage.

(NDTV)

The bran in whole wheat flour contains oil which is prone to turning rancid.

To minimize spoilage and increase the shelf life, try storing your whole wheat flour in a dry and cool place in an airtight container. If you intend to store the flour for an extended period of time, it’s best to refrigerate it.

9. Whole-grain pasta packs a significantly larger amount of fiber per serving than its refined counterpart.

(Healthline)

When looking at whole grains vs. refined grains, we can observe a few pretty interesting things. For instance, one cup of cooked whole-wheat spaghetti packs only 174 calories, while refined spaghetti tops that with 220 kcal.

When looking at protein content, whole wheat has a respectable 7.5 grams, while the refined option 8.1. Carbohydrate content is also higher for refined pasta (43 grams and 37 grams for whole wheat).

However, the whole wheat option has six grams of fiber per cup compared to the refined product’s 2.5 grams. The same trend goes for fat content, with the whole wheat pasta having only 0.8 grams of fat, in contrast to the 1.3 grams that the refined pasta packs.

All in all, whole-grain pasta is higher in manganese, selenium, copper, magnesium, and phosphorus, with a lower calorie, fat, carb, and higher overall fiber content. Pasta made from refined grains, on the other hand, had a higher content of iron and B vitamins.

10. Refined grains are whole grains devoid of bran and germ.

(Healthline, The Mayo Clinic Diet)

Refined grains get their smooth fine texture through milling. However, they lose bran, germ, and other nutrients like fiber in the process. White flour, white bread, and white rice are just some of the numerous forms of refined grains.

Here are some more whole grain fun facts. Refined grains are often used to produce processed foods due to their long shelf life.

Whole-Grain Types

Barley, brown rice, buckwheat, and similar whole grains are well-liked established whole grains. But have you heard of teff, farro, or kaniwa? Though less known, they’re equally healthy and beneficial.

Stay with us as we walk you through these and other types of whole-grain varieties you’re likely to encounter.

11. Teff—the ancient grain—has seen a rise in popularity in Europe over the past decade.

(CBI Ministry Of Foreign Affairs)

Europe has seen significant growth when it comes to the market demand in special and niche cereals throughout the last decade.

When it comes to different whole-grain types, teff had seen a rise in import growth from 6,200 tons in 2013 to 7,800 tons in 2017.

12. Quinoa imports have almost tripled in Europe between 2013–2017.

(CBI Ministry Of Foreign Affairs)

As the whole-grain food market managed to break more ground in the old continents, quinoa imports have grown from 9,300 tons to a staggering 27,000 tons in the above period.

13. Farro is the name of a nutritious ancient grain.

(The Spruce Eats)

Ancient grains are typically those types of whole-grain foods that have been cultivated in the same way for hundreds, if not thousands of years.

As you may know, most plants and grains have been selectively bred to become larger, have a better yield, or to become more economical, resist the elements, etc.

By contrast, ancient grains are those that have virtually seen no changes in their cultivation for centuries.

14. Kaniwa is also called “baby quinoa.”

(The Spruce Eats)

Like quinoa, kaniwa is also a seed and technically not a grain, and when it’s dry, it looks like a smaller version of the auburn brown quinoa.

Even though not the same as quinoa, most people refer to it as “baby quinoa.” They are related but aren’t the same thing.

15. Bulgur wheat is loaded with thiamine, which is highly beneficial for the nervous and digestive systems.

(Health Benefits Times)

By now, you’ve probably noticed that the whole-wheat grain nutrition facts are pretty fascinating and favorable for anyone looking to improve their diet.

Bulgur, for instance, is full of different B vitamins, such as niacin and thiamine. The latter is highly beneficial for the nervous and digestive systems, while niacin helps the body digest proteins better.

Bulgur also contains significant amounts of riboflavin, iron, zinc, selenium, and magnesium.

16. One-third of the world eats millet as a core part of their diet.

(The Spruce Eats)

As a matter of fact, when it comes to different whole-grain types, millet is one of the earliest cultivated ones, having more than 6,000 varieties across the globe.

It’s mostly used as the staple ingredient for beer and fermented beverages, porridges, and flatbreads.

In the US, millet is used chiefly for producing gluten-free bread, either solely or together with other gluten-free grains.

17. One cup of freekeh packs 11 grams of dietary fiber.

(Nutritionix)

In terms of its whole-grain nutritional value, freekeh packs quite the punch. Namely, a cup of this cereal has 202 calories, 0.6 grams of fat, 0 cholesterol, 165 mg of potassium, 0.2 gram of sugar, 7.5 grams of protein, and 45 grams of carbohydrates.

18. Barley may help fight coronary heart disease.

(The Spruce Eats, FDA)

The FDA also states that soluble fiber from barley can help lower cholesterol. Apart from that, the grain’s insoluble fiber content can help reduce the risk of developing colon cancer and type 2 diabetes.

A 1-cup serving of the grain has 193 calories, 3.5 grams of protein, and around 6 grams of fiber.

19. Buckwheat production has been fluctuating in the US in recent years.

(Statista)

When looking at the whole-grain industry growth in terms of buckwheat, we face a pretty much stagnant tendency.

To be more precise, according to the latest larger data pools, the US production volume of buckwheat was about 76.36 thousand metric tons. The most significant production volume was achieved in 2009 (86,258 thousand metric tons), and it has shown a roller-coaster-like tendency ever since.

Benefits of Whole Grains

Ever wondered why porridge is the ideal breakfast for many health enthusiasts? The answer is pretty straightforward. Including healthy whole-grain foods like steel-cut oats in your everyday diet improves your overall health due to their immensely nutritious nature.

The following paragraphs discuss all the benefits of whole grains, as well as potential side effects.

27. Whole grains are high in fiber and nutrients.

(Healthline)

When looking at the list of whole-grain foods and their nutritional value, it’s easy to spot the following benefits they carry.

All of them are generally high in fiber, with the bran providing most of it. They are also high in B vitamins, including folate, thiamine, and niacin. They contain many different minerals, too, like magnesium, iron, zinc, and manganese.

Like most grains, they also have a considerable amount of proteins for each serving, and they also have several compounds that act as antioxidants. These include ferulic acid, sulfur compounds, phytic acid, and lignans.

Lastly, they are also known to carry different plant compounds (sterols, stanols, and polyphenols) that can help fight or prevent diseases.

28. Eating more whole-grain foods to lose weight is a good idea.

(NCBI, Healthline)

Fiber-rich foods, in general, can help prevent overeating. As whole-grain foods are high in fiber, they are more filling than their refined counterparts, and research seems to back up the claim that they can lower the risk of obesity.

Over 15 studies suggest that eating at least three servings of whole-grain products can lower the body mass index (BMI).

29. Consuming whole grains may prevent cardiovascular diseases.

(Healthline)

Whole-grain bread, cereals, and bran have explicitly been associated with a decreased heart disease risk. According to whole-grain nutrition, three 1-oz servings of whole grains a day could reduce your risk of heart disease by 22%.

30. Whole grains are good for the digestive system.

(Health)

These foods are also known to boast an array of digestive benefits too. Eating whole wheat has benefits that include regular bowel movements and warding off diverticulosis (pouches that form on the colon wall, causing inflammation, diarrhea, constipation, and pain).

Moreover, these grains contain lactic acid, which promotes the growth of “good bacteria” within the large intestine, aiding digestion and helping the body absorb nutrients better.

31. Eating whole grains can decrease the risk of type 2 diabetes.

(Healthline)

The whole-grain nutrition profile is to thank for this. Whole grains are an excellent source of fiber and magnesium, the two crucial nutrients for type 2 diabetes prevention.

Fiber helps you manage your satiety, keep your weight in check, and prevent obesity—a condition commonly linked with developing type 2 diabetes.

Furthermore, magnesium assists your body in metabolizing carbs and improves insulin sensitivity, thus lowering blood sugar levels. A minimum of two servings of whole grains in your daily diet is enough to keep your blood sugar levels in check.

32. Some types of whole grain may cause allergies.

(Healthline)

Whole grains like barley, wheat, and rye contain gluten. This protein causes allergic reactions in people with celiac disease, gluten sensitivity, and gluten allergy.

Luckily, gluten-free whole grains such as buckwheat, oats, amaranth, and rice are suitable for those with sensitivities.

Whole-Grain Foods: Nutritional Value

Did you know that the germ is a rich source of healthy fats, E and B vitamins, antioxidants, and phytochemicals? Or that the endosperm of the whole grain contains carbohydrates, minerals, and proteins?

Read on to find out more nutritional facts we’ve got in store for you.

33. Half a cup of whole-grain oats packs 150 calories and only 2.5 grams of fat.

(EatThisMuch)

When observing whole-grain oats’ nutrition facts, it’s clear why this food has many health benefits.

Half a cup of whole-grain oats also has 4 grams of fiber, 27 grams of carbohydrates, 6 grams of protein, and 1.8 mg of iron, 23% of the recommended daily intake.

34. Ezekiel bread boasts several types of legumes and grains.

(MedicalNewsToady)

It’s made from sprouted whole grains that may provide extra nutrients compared to other whole-grain bread types.

When it comes to whole-grain bread, the nutrition benefits of one slice (or 45 grams) of Ezekiel bread are as follows:

140 calories
22 grams of carbs
5 grams of protein
4 grams of fiber
2.5 grams of fat

It’s also worth noting that Ezekiel bread may include riboflavin, niacin, iron, and calcium.

35. A serving of brown rice contains 216 calories.

(NutritionData)

When it comes to whole-grain brown rice, the nutrition facts reveal impressive numbers. Namely, a serving of whole-grain brown rice contains 5 grams of protein, 44.8 grams of carbs, 3.5 grams of dietary fiber, 1.8 grams of total fat, 0.2 mg of thiamin, 3 mg of niacin, and 7.6 mcg of folate.

36. Consuming exclusively whole grains may decrease your folate levels.

(Mayo Clinic)

Unlike refined grain foods, healthy whole-grain foods lack folic acid, as they aren’t fortified with it in the production process. Therefore, people who don’t consume other types of grain besides whole grains may require folate supplementation or the inclusion of folate-rich foods.

To maintain a balanced diet and optimum folate levels, especially during pregnancy, include folate-rich foods such as fortified ready-to-eat cereals, legumes, etc.

FAQs

What percentage of grains should be whole?

When it comes to grain consumption, they should account for a rather significant portion of your daily intake, around 30%. However, when it comes to whole grains, experts from the US Department of Agriculture recommend that at least half of that 30% should come from whole grains. For starters, they contain more fiber and are also more abundant in nutrients than the regular-grain options.

(Federal Occupational Health)

How much healthier is whole-grain wheat?

According to experts, whole-grain wheat products pack a wide array of different health benefits compared to their refined-grain counterparts.

First of all, whole grains digest at a slower rate, positively affecting insulin and blood sugar levels.

They are also known to help reduce the risk of developing type 2 diabetes. According to a study, women who ate at least five grams of more whole-grain fiber from cereals had a reduced risk of developing type 2 diabetes, about 30% compared to those who ate only around 2.5 grams of the same fiber sources each day.

One of the many whole-grain benefits includes better weight control. According to a study, those women who ate at least three or more servings of whole-grain sources throughout the day had noticeably lower BMIs (body mass indexes) than those who had less than a serving per day.

Whole-grain sources may help the body fight off the symptoms of metabolic syndrome. The research data currently available reveals that metabolic syndrome was less prevalent in people who ate higher amounts of whole-grain and cereal fiber than those who had a diet low in fibers and whole grains.

(WebMD)

How many grams of whole grain should you eat a day?

According to the Grains & Legumes Nutrition Council, the daily target intake of whole grains should be around 48 grams for adults and children older than nine. For kids aged between 3–9, the daily target intake should be between 32–40 grams, while for children between 1–3 years old, the daily intake should be at or around 24 grams.

To meet the recommended 48 grams for adults and youngsters, GLNC recommends eating two biscuits (whole wheat), which pack around 30 grams of whole-grain and one wholemeal sandwich (40 grams of whole-grain).

A quarter cup of muesli (35 grams) and three whole-grain crispbreads (around 30 grams of whole-grain) should also do the trick.

(Grains & Legumes Nutrition Council)
