According to Gram Research analysis, following the Dutch Wheel of Five food guidelines significantly improves your vitamin and mineral intake, with recommended foods providing 50-75% of needed vitamins and 50-65% of needed minerals. However, foods outside these guidelines supply important nutrients like vitamin A and sodium, meaning a truly healthy diet requires both recommended foods and careful variety beyond the guidelines.
A study of nearly 1,750 Dutch adults found that following the country’s official food recommendations—called the Wheel of Five—helps people get more vitamins and minerals. However, the research also discovered that foods outside these recommendations provide important nutrients too, especially vitamin A and sodium. The study looked at what people ate over two days and measured how much of each vitamin and mineral they consumed. The findings suggest that while sticking to official guidelines is helpful, a varied diet that includes some foods outside the recommendations may be necessary for complete nutrition.
Key Statistics
A 2026 cross-sectional study of 1,747 Dutch adults found that foods within the Wheel of Five guidelines provided 50-75% of recommended vitamin intake and 50-65% of recommended mineral intake.
According to research reviewed by Gram from the Dutch National Food Consumption Survey (2019-2021), foods outside official dietary guidelines supplied more than 70% of sodium intake and 55-60% of vitamin A intake in the study population.
A 2026 analysis of 1,747 adults showed that better adherence to the Wheel of Five recommendations was most strongly associated with improved intake of vitamin D, B vitamins (B3 and B12), vitamin C, selenium, copper, potassium, and phosphorus.
Research from 1,747 Dutch participants revealed that while official food guidelines improve micronutrient intake, no single set of recommended foods provides 100% of all necessary vitamins and minerals.
The Quick Take
- What they studied: Whether following the Dutch Wheel of Five food recommendations helps people get enough vitamins and minerals in their diet
- Who participated: 1,747 Dutch adults between ages 18 and 79 who reported everything they ate over two separate days
- Key finding: Foods recommended by the Wheel of Five provided 50-75% of needed vitamins and 50-65% of needed minerals, but foods outside the guidelines supplied important nutrients like vitamin A and sodium
- What it means for you: Following official food guidelines helps you get better nutrition, but you shouldn’t ignore foods outside these recommendations—a balanced diet needs both types of foods to meet all your nutritional needs
The Research Details
Researchers used information from the Dutch National Food Consumption Survey, which tracked what 1,747 adults ate during 2019-2021. Each person reported everything they consumed over two separate 24-hour periods. The scientists then calculated how much of each vitamin and mineral came from foods that fit the Wheel of Five recommendations versus foods that didn’t.
They measured how well people followed the guidelines and compared this to their actual vitamin and mineral intake. They used special charts called radar graphs to show which nutrients improved most when people ate more recommended foods. This type of study is called cross-sectional because it takes a snapshot of people’s eating habits at one point in time, rather than following them over months or years.
This approach is important because it shows real-world eating patterns from actual people, not just laboratory conditions. By looking at two days of eating for each person, the researchers captured more realistic information than asking people to remember their diet from memory. The study helps us understand whether official food guidelines actually work in practice for helping people get proper nutrition.
The study included a large, representative sample of Dutch adults across different ages. Using two separate 24-hour recalls makes the data more reliable than asking people to remember one day. However, because this is a snapshot study rather than following people over time, we can’t prove that following guidelines causes better nutrition—only that they’re connected. The study was based on real food consumption data from a national survey, which adds credibility.
What the Results Show
The research showed that foods within the Wheel of Five guidelines provided about half to three-quarters of the recommended daily amounts of vitamins and minerals. Specifically, recommended foods supplied 50-65% of needed minerals and 50-75% of needed vitamins. The more closely people followed the Wheel of Five recommendations, the more vitamins and minerals they consumed overall.
The nutrients that improved most when people followed the guidelines were vitamin D, B vitamins (B3 and B12), vitamin C, selenium, copper, potassium, and phosphorus. These nutrients showed the strongest connection to better adherence to the food recommendations.
However, foods outside the Wheel of Five guidelines were crucial for certain nutrients. These foods provided more than 70% of sodium intake and 55-60% of vitamin A intake. This means that while the guidelines are helpful, they don’t tell the whole story about good nutrition.
The study revealed that no single set of recommended foods can provide 100% of all needed nutrients. Different foods contribute different amounts of various vitamins and minerals. Some nutrients like sodium and vitamin A are found more commonly in foods outside the official recommendations, suggesting that dietary variety beyond the guidelines is necessary for complete nutrition.
This research aligns with general nutrition science showing that official dietary guidelines help improve overall nutrient intake. However, it adds an important finding: guidelines alone aren’t sufficient. Previous research has suggested this, but this study provides specific data showing exactly which nutrients come from outside the recommended foods. The finding that 50-75% of vitamins come from recommended foods suggests guidelines are a good foundation but need supplementation with other foods.
This study only captured what people ate on two days, which may not represent their typical eating patterns. People might have eaten differently on those days than they usually do. The study was conducted in the Netherlands, so results may not apply to other countries with different food cultures and different dietary guidelines. Additionally, because this is a cross-sectional study, we can see that following guidelines is connected to better nutrition, but we can’t prove that the guidelines actually cause the improvement—other factors could be involved.
The Bottom Line
Follow the Wheel of Five food recommendations as a foundation for good nutrition—the evidence strongly shows this improves your vitamin and mineral intake. However, don’t limit yourself only to recommended foods. Include a variety of other foods in your diet, especially for nutrients like vitamin A and sodium that come primarily from foods outside the guidelines. This balanced approach gives you the best chance of meeting all your nutritional needs. Confidence level: High for the benefit of following guidelines; Moderate for the specific nutrient gaps identified.
Everyone should care about this research, especially people trying to eat healthier or manage their nutrition. It’s particularly relevant for people following strict diets or those concerned about getting enough vitamins and minerals. Healthcare providers and nutritionists can use this information to counsel patients. However, people with specific medical conditions or nutrient deficiencies should consult a healthcare provider rather than relying solely on general guidelines.
You may notice improved energy levels and general health within a few weeks of improving your diet according to these guidelines. However, some benefits like stronger bones (from better calcium and vitamin D intake) or improved immune function (from better vitamin C intake) may take months to become noticeable. Consistent eating habits over months and years show the most significant health benefits.
Frequently Asked Questions
Do I need to follow food guidelines to get enough vitamins and minerals?
Following food guidelines like the Wheel of Five significantly improves your micronutrient intake, providing 50-75% of needed vitamins. However, you also need foods outside the guidelines for complete nutrition, particularly for vitamin A and sodium. A balanced approach using both recommended and varied foods works best.
What vitamins improve most when I follow dietary guidelines?
Research shows vitamin D, B vitamins (B3 and B12), vitamin C, selenium, copper, potassium, and phosphorus improve most when following the Wheel of Five guidelines. These nutrients show the strongest connection to better adherence to official food recommendations.
Can I get all my nutrients from recommended foods only?
No. While recommended foods provide 50-75% of vitamins and 50-65% of minerals, foods outside guidelines supply crucial nutrients like vitamin A (55-60% of intake) and sodium (over 70% of intake). Dietary variety beyond guidelines is necessary for complete nutrition.
How quickly will I see health benefits from following food guidelines?
You may notice improved energy within weeks of better eating habits. However, benefits like stronger bones or improved immunity typically take months to become noticeable. Consistent healthy eating over months and years produces the most significant health improvements.
Are food guidelines the same in every country?
No. This study examined Dutch guidelines (the Wheel of Five), which may differ from guidelines in other countries. Your country’s dietary guidelines may recommend different foods based on local food availability and nutritional research specific to your population.
