A new Saudi Healthy Eating Index successfully measures diet quality in ways similar to established tools, showing strong agreement with the American Healthy Eating Index (correlation of 0.867), according to a 2026 cross-sectional study of 702 Saudi adults. However, the tool showed weak internal consistency and needs refinement before healthcare providers can rely on it for individual patient assessments.
Researchers in Saudi Arabia created a new tool called the Saudi Healthy Eating Index (SHEI) to measure how well people follow healthy eating guidelines. Scientists tested this tool on 702 adults in two Saudi cities using detailed food records and found it works well for comparing diets to other nutrition standards. However, the tool needs some improvements before doctors can rely on it completely. This research shows promise for helping people understand their eating patterns, but more testing is needed to make sure it’s accurate and consistent.
Key Statistics
A 2026 cross-sectional study of 702 Saudi adults found that the new Saudi Healthy Eating Index correlated strongly with the established American Healthy Eating Index at 0.867, indicating the tools measure similar healthy eating patterns.
The Saudi Healthy Eating Index identified five underlying dietary dimensions in eating patterns that together explained 57.39% of the variation in how Saudi adults eat, according to Gram Research analysis of the 2026 study.
The Saudi Healthy Eating Index showed low internal consistency with a Cronbach’s alpha of only 0.237 in a 2026 study of 702 participants, suggesting the tool needs improvement before being used to assess individual eating habits.
A 2026 study of 702 Saudi adults found that people with higher Saudi Healthy Eating Index scores weighed slightly less, with a weak but statistically significant negative correlation of -0.103 between diet quality and body weight.
The Quick Take
- What they studied: Whether a new Saudi diet-scoring tool accurately measures how well people follow healthy eating recommendations from the Saudi Healthy Plate Guide.
- Who participated: 702 Saudi adults living in Riyadh and Al-Madinah who provided detailed records of everything they ate over 24 hours, along with their height, weight, and basic background information.
- Key finding: The new Saudi diet score matched very closely with an established American diet-scoring system (correlation of 0.867), suggesting it measures similar healthy eating patterns, but the tool showed weak consistency when measuring the same person multiple times.
- What it means for you: This tool could eventually help you track whether you’re eating according to Saudi dietary guidelines, but it needs refinement before healthcare providers should use it as their main measurement tool. It’s a promising start that requires more development.
The Research Details
Scientists conducted a secondary analysis, meaning they used data that had already been collected from 702 Saudi adults. Participants reported everything they ate over a 24-hour period using a detailed interview method called multiple-pass recall, where researchers ask questions multiple times to ensure nothing is forgotten. The researchers also measured each person’s height and weight and collected information about their age, gender, and other background details.
The team then created a scoring system based on the Saudi Healthy Plate Guide 2024, which recommends specific amounts of vegetables, fruits, whole grains, proteins, and dairy. They tested whether this new scoring tool (SHEI) worked properly by comparing it to an established American diet-scoring system (HEI-2015) that has been used successfully for years.
The researchers examined five important qualities: whether the tool measured what it was supposed to measure, whether it gave consistent results, whether it matched other similar tools, and how different food groups related to each other in the scoring system.
Creating a diet-scoring tool specifically for Saudi Arabia is important because people in different countries eat different foods and follow different cultural eating patterns. An American diet-scoring tool might not accurately reflect what healthy eating looks like in Saudi Arabia. This research helps develop tools that are tailored to local eating habits and guidelines, making them more useful for doctors, nutritionists, and public health programs in the region.
The study included a reasonably large sample of 702 people from two major Saudi cities, which is a strength. However, the researchers note that the food database used to create the scoring system had limitations, and the sample may not represent all Saudis equally well. The study’s cross-sectional design means it captured a snapshot in time rather than following people over months or years, which limits what we can conclude about long-term eating patterns.
What the Results Show
The Saudi Healthy Eating Index showed strong agreement with the established American diet-scoring system, with a correlation of 0.867 (on a scale where 1.0 is perfect agreement). This means the two tools identified similar patterns of healthy and unhealthy eating, suggesting the new Saudi tool measures what it’s supposed to measure.
When researchers tested example menus that nutrition experts considered exemplary (very healthy), the SHEI gave them moderate to high scores, which is what you’d expect. The tool also identified five main dietary patterns in the data—like vegetable consumption, fruit intake, whole grain choices, protein sources, and dairy products—which together explained 57.39% of the variation in people’s eating habits.
However, the tool showed a weakness in internal consistency, meaning it didn’t always give reliable results when measuring the same eating patterns. The consistency score (Cronbach’s alpha) was only 0.237, which is considered low. Additionally, the connections between different food groups in the scoring system were weak to moderate, suggesting the components don’t work together as smoothly as they should.
The study found that body weight showed a weak negative relationship with the diet score (r = -0.103), meaning people with higher diet scores tended to weigh slightly less, though this relationship was statistically significant. This makes sense because healthier eating patterns are generally associated with healthier body weights. The five dietary dimensions identified in the analysis suggest that eating habits in Saudi Arabia can be broken down into distinct categories, which could help nutritionists provide more targeted advice.
According to Gram Research analysis, this study builds on existing diet-scoring tools like the Healthy Eating Index used in the United States. The strong correlation with the HEI-2015 suggests that healthy eating principles are similar across cultures, even though specific foods differ. However, the low internal consistency is a concern that distinguishes this tool from more established scoring systems, indicating it needs refinement before widespread use.
The researchers acknowledge several important limitations. The food database used to score the diet may not include all foods commonly eaten in Saudi Arabia, which could affect accuracy. The study only included people from two cities, so results may not apply to all Saudis, particularly those in rural areas or different regions. The cross-sectional design means researchers captured eating habits at only one point in time, so they can’t determine whether the tool accurately tracks changes in diet over weeks or months. Finally, the low internal consistency suggests the tool may need redesign before it can reliably measure individual eating patterns.
The Bottom Line
The Saudi Healthy Eating Index shows promise as a research tool for comparing dietary patterns across groups of people (moderate to high confidence), but it’s not yet ready for individual health assessments (low confidence). Healthcare providers should continue using established tools until the SHEI undergoes further testing and refinement. If you’re interested in tracking your diet against Saudi guidelines, work with a registered dietitian who can provide personalized guidance rather than relying solely on this emerging tool.
Public health researchers in Saudi Arabia and the Middle East should pay attention to this work, as it provides a foundation for developing region-specific diet assessment tools. Nutritionists and dietitians may find it useful for research purposes. Individual consumers should not yet use this tool as their primary method for assessing diet quality, as it needs more development. Healthcare policymakers should consider supporting further research to improve the tool’s reliability.
If the SHEI is refined based on this feedback, it could become a useful tool within 2-3 years. However, meaningful improvements in eating habits typically take 4-12 weeks to show measurable changes in health markers, regardless of which assessment tool is used.
