Nearly 24 years of what Americans' bodies contain, in one document.
For nearly a quarter century, the CDC has been quietly taking the biochemical pulse of a nation — measuring what lives in the blood and urine of Americans from age one onward, translating diet into data. In 2026, that long accumulation resolves into a single landmark report: 131 nutritional biomarkers, 24 years of trends, and a standardized mirror in which policymakers, clinicians, and researchers can finally see the full arc of how America eats and what that eating costs. It is not a verdict, but a vocabulary — the shared reference point from which meaningful questions about nutrition, disparity, and public health can now be asked with precision.
- Micronutrient deficiencies, rising supplement use, and persistent obesity have left public health officials without a unified, long-range nutritional baseline — until now.
- The sheer scale of the release is disorienting in the best sense: over 2,700 tables and 500 figures synthesizing data that previously existed only in fragmented survey cycles.
- For the first time, the report separates supplement users from nonusers, revealing how voluntary nutritional choices are reshaping population-level biomarker profiles.
- Clinicians gain something practical and immediate — standardized reference intervals drawn from nationally representative data, giving real-world context to individual patient lab results.
- The 24-year trend lines expose not just where American nutrition stands today, but how it has shifted across demographic groups, making disparities visible and trackable over time.
For nearly a quarter century, the CDC has been drawing blood and collecting urine samples from Americans across the country, measuring the biochemical evidence of how a nation eats. In June 2026, that effort culminates in a single comprehensive report covering 131 nutritional biomarkers — vitamins, minerals, fatty acids, trace elements, and more — drawn from the National Health and Nutrition Examination Survey between 1999 and August 2023.
NHANES is no ordinary survey. Participants undergo physical exams, detailed health interviews, dietary questionnaires, and biological sampling. The results are nationally representative, and what sets the program apart globally is its ability to link nutritional biomarkers directly to sociodemographic, lifestyle, and medical data — connecting what's in someone's blood to their age, income, and health history in ways few countries can replicate.
Earlier CDC nutrition reports tracked as few as 27 biomarkers over a single survey cycle. This new report synthesizes everything into one document containing more than 2,700 tables and 500 figures. It introduces a combined vitamin B12 status indicator, presents the omega-3 index as a measure of cardiovascular health, tracks 21 individual red blood cell fatty acids, and — for the first time — distinguishes the nutritional profiles of supplement users from those who take none.
The report's deepest value is its longitudinal view: not a snapshot but a 24-year trend line, broken down by age, sex, race, and Hispanic origin. Policymakers can identify where deficiencies are growing and in whom. Clinicians gain standardized reference intervals to interpret patient lab results. Researchers receive what the authors call gold-standard data for validating studies and building guidelines. The report is deliberately descriptive and unadjusted, leaving interpretation open so that different users can extract different truths.
The data arrives as questions about American nutrition remain urgent — obesity rates high, micronutrient gaps persistent, supplement culture expanding. The report will not resolve these tensions on its own, but it gives everyone working on them a common, rigorously constructed place to begin.
For nearly a quarter century, the CDC has been collecting blood and urine samples from Americans in a mobile examination center, measuring what their bodies contain: vitamins, minerals, fatty acids, caffeine metabolites, and dozens of other chemical markers that tell the story of how well the nation is eating. In June 2026, all of that data—nearly 24 years of it, from 1999 through August 2023—will be released in a single standardized report covering 131 distinct nutritional biomarkers across the entire US population aged one year and older.
The National Health and Nutrition Examination Survey, or NHANES, is not a simple questionnaire. Participants answer detailed health interviews, complete questionnaires about what they eat and drink, undergo physical examinations, and provide biological samples. The survey is nationally representative, meaning the results reflect the broader American population. What makes NHANES unusual, even globally, is that it doesn't just measure disease markers like blood glucose or cholesterol. It measures nutrition itself—the actual biochemical evidence of what people are consuming and how their bodies are processing it.
The scope of what the 2026 report will contain is staggering. Earlier CDC nutrition reports tracked 27 biomarkers for 1999 to 2002, then 58 for 2003 to 2006. The most recent single survey cycle, from August 2021 to August 2023, captured 50 biomarkers. But this new report synthesizes all of it into one document containing more than 2,700 tables and 500 figures. It will show vitamin B12 status using a combined indicator that includes methylmalonic acid and homocysteine levels. It will present the omega-3 index—a measure of heart health derived from red blood cell fatty acids. It will break down trace elements like copper and zinc, separate out different forms of folate, and track 21 different red blood cell fatty acids individually. For the first time, it will show how supplement users and nonusers differ in their nutritional status.
The report's real power lies in its presentation of trends. Instead of a snapshot, it offers a 24-year video of American nutrition. The standardized tables and figures will show how biomarker concentrations have shifted across survey cycles, broken down by age, sex, race, and Hispanic origin. Readers will be able to see not just what Americans' nutritional status is, but how it has changed—and where disparities exist between demographic groups.
For policymakers, the utility is direct. If a particular vitamin deficiency is rising in a specific population, the data will show it clearly. For clinicians, the report provides the reference intervals—the normal ranges—that they need to interpret their patients' test results. For researchers, it offers what the authors describe as "gold standard scientific data" that can be used to validate studies, develop guidelines, and explore the connections between nutrition and health outcomes. The report is intentionally descriptive and unadjusted, meaning it presents the raw patterns without imposing interpretation. That flexibility allows different users to extract different insights.
NHANES stands apart globally because relatively few countries conduct national nutrition surveys at all, and fewer still combine detailed nutritional biomarkers with the kind of sociodemographic, lifestyle, and medical history data that NHANES collects. That combination—the ability to link what's in someone's blood to their age, income, medical conditions, and behavior—is what makes the data valuable for identifying not just problems but their roots.
The 2026 report arrives at a moment when questions about American nutrition are urgent. Obesity rates remain high. Micronutrient deficiencies persist in certain populations. Supplement use has grown. The data will not answer these questions by itself, but it will provide the common reference point that policymakers, clinicians, and researchers need to ask them intelligently and to measure whether their answers are working.

La Conversación del Hearth Otra perspectiva de la historia
Why does it matter that this report comes out now, in 2026? What changes about having 24 years instead of, say, 10?
With 24 years, you can see real patterns emerge. A blip in one survey cycle might be noise. But if something has been moving in the same direction for two decades, that's a signal. You can see whether interventions actually worked.
The report has 2,700 tables. Who actually reads that?
Different people read different parts. A cardiologist might pull the omega-3 data. A state health department might look at vitamin D trends in children. A researcher studying health disparities might cross-reference folate levels with race and income. The standardization is what matters—everyone's looking at the same numbers, the same way.
You mentioned this is descriptive, not adjusted. What does that mean in practice?
It means the report shows you what the data shows, without trying to explain it away or control for confounding factors. If one group has lower B12 levels, the report shows that. It doesn't try to say whether that's because of diet, genetics, medication, or something else. That's left to the researcher or clinician to figure out.
Why separate supplement users from nonusers?
Because supplement use changes the picture entirely. If you're taking a multivitamin, your blood vitamin levels look different than someone who isn't. For the first time, this report lets you see both sides clearly. That matters for understanding what's actually happening in people's bodies.
What would a policymaker actually do with this?
They could see that, say, folate deficiency is rising in pregnant women in a particular region, and decide to fund a public health campaign or change food fortification policy. Or they could track whether a program they started five years ago actually moved the needle. It's the evidence base for action.
