Gram Research analysis of a 2026 study found that adults with chronic spinal cord injury reported eating 34% less energy than matched controls, and their nutrient levels were lower overall. After accounting for the smaller calorie intake, nutrient adequacy and diet quality scores were similar. Their main nutritional risk appears to come from eating less, not poorer food choices.
According to research reviewed by Gram, adults with chronic spinal cord injury (SCI) reported eating about 34% less energy than adults without injuries of the same age and sex. Their overall nutrient levels were lower too, and more than 90% of them fell below a recommended threshold for vitamin D and vitamin E. However, once researchers accounted for the smaller calorie intake, the nutrient and diet quality scores of both groups looked similar. This suggests that nutritional risk after a spinal cord injury may come mainly from eating less food overall, not from making poorer food choices. Because the study was small and only looked at one point in time, it cannot prove cause and effect. Still, it points to a practical idea: when calories are limited, each bite should count for more nutrients.
Key Statistics
A 2026 cross-sectional study of 106 adults found that people with chronic spinal cord injury reported 34% lower energy intake than age- and sex-matched controls.
In a 2026 study of 53 adults with chronic spinal cord injury, more than 90% fell below the prespecified nutrient adequacy threshold for vitamin D and vitamin E.
A 2026 study comparing 53 adults with spinal cord injury to 53 matched controls found that nutrient differences disappeared after adjusting for energy intake, with the injured group eating 613.4 kcal per day less at a common resting metabolic rate.
The Quick Take
- What they studied: Researchers wanted to know whether adults with long-term spinal cord injuries get enough nutrients, and whether any shortfall comes from poor food choices or from eating fewer calories.
- Who participated: The study included 53 adults with chronic spinal cord injury and 53 adults without the injury who were matched by age and sex, for 106 people in total. They were recruited through a university-based research center and asked to keep detailed food diaries for three days.
- Key finding: Adults with spinal cord injuries reported eating about 613 calories per day less than the comparison group, even after adjusting for how much energy their bodies burn at rest. Once this lower calorie intake was taken into account, their nutrient levels and diet quality scores were similar to the comparison group.
- What it means for you: If you live with a spinal cord injury or support someone who does, the biggest nutrition challenge may be getting enough nutrients from a smaller amount of food. Choosing nutrient-rich foods, such as vegetables, fish, eggs, and fortified foods, may help fill gaps, but a registered dietitian can give advice tailored to your needs.
The Research Details
This was a cross-sectional study, which means researchers took a snapshot of people’s eating habits and body measurements at one point in time. Each participant with a spinal cord injury was paired with a comparison adult of the same age and sex, which helps make the two groups more fair to compare.
Participants filled out three-day food records, writing down everything they ate and drank. A registered dietitian reviewed these records to check for accuracy and detail. The research team also measured each person’s resting metabolic rate, which is the number of calories the body burns while at rest, and used it as a common reference point.
Using this reference point, researchers could compare nutrient levels fairly, even though people with spinal cord injuries often have lower energy needs. They calculated nutrient adequacy ratios, which show how close someone’s intake comes to recommended levels, and scored overall diet quality using a standard tool called the Healthy Eating Index-2020.
Measuring food intake against resting calorie burn is important because people with spinal cord injuries often burn fewer calories than others. Without this step, it would be hard to tell whether lower nutrient intake reflects poor food choices or simply a smaller amount of food. The comparison also includes diet quality scores, which show how well food choices match general healthy eating patterns, not just how much of each nutrient is eaten.
The study used careful methods, including a matched comparison group, food records reviewed by a dietitian, and measured resting metabolic rate. These strengths make the comparison more trustworthy. However, the study had a modest number of participants, was conducted at one research center, and collected information at only one point in time. Food records also depend on people accurately remembering and reporting what they ate, which can introduce errors. The study has not yet been repeated by other research teams, so its results should be viewed as an early, useful signal rather than a final answer.
What the Results Show
Adults with spinal cord injuries reported eating 34% less energy than the comparison group. On average, this was about 613 calories per day less when both groups were compared at the same resting calorie burn. This large gap suggests that many people with spinal cord injuries are eating considerably less food overall.
Before accounting for this difference, nearly every nutrient was lower in the spinal cord injury group, with vitamin B12 as the only exception. Their overall nutrient adequacy score was also lower. This means that, on paper, people with spinal cord injuries appeared to be getting fewer nutrients than the comparison group.
However, when researchers adjusted the nutrient numbers to account for the smaller calorie intake, the differences disappeared. Both groups had similar nutrient density, meaning the amount of nutrients per 1,000 calories was about the same. Diet quality scores were also similar between the groups, which suggests that the food choices themselves were not clearly worse.
Nutrient gaps were still notable in the spinal cord injury group. More than 90% of participants in that group fell below the study’s threshold for vitamin D and vitamin E. Total diet quality scores in both groups also showed room for improvement, meaning even the comparison group had diets that could be healthier.
Several food groups, such as total fruits, vegetables, or grains, were eaten in smaller amounts by people with spinal cord injuries. When these amounts were measured per 1,000 calories, however, the differences largely disappeared. This points again to smaller overall food volume rather than a clear preference for unhealthy foods.
The study also found that the overall diet quality scores were similar in both groups, and the component scores that make up the total were close as well. This suggests that people with spinal cord injuries may be making reasonable choices within the amount of food they eat, though there is still room to improve nutrient density.
Researchers in nutrition have long noted that people with spinal cord injuries often burn fewer calories and may eat less, which can make it harder to meet nutrient needs. This study adds to that picture by showing that the nutrient gap largely tracks with lower calorie intake rather than with worse overall diet quality. Research shows that adjusting for energy intake is an important step when comparing diets, and this study applies that approach to a group that is often overlooked in nutrition research.
The study included only 53 adults with spinal cord injuries and 53 comparison adults, so the results may not apply to everyone with a spinal cord injury, including people with different injury levels, ages, or living situations. The study was conducted at a single university-based center, which may limit how well the findings generalize to other communities.
Because it was a cross-sectional study, it can show that lower energy intake and lower nutrient levels are linked, but it cannot prove that one causes the other. Food records rely on people remembering and reporting their meals accurately, and three days may not capture typical eating patterns over time. Finally, the study did not measure whether nutrient levels in the blood or body were actually low, so the nutrient adequacy ratios describe intake, not confirmed deficiency.
The Bottom Line
Research shows that adults with chronic spinal cord injuries reported eating far fewer calories than comparable adults, and that their nutrient gaps appear to follow from this lower intake. Based on this study, a reasonable approach is to focus on nutrient-dense foods, which provide many vitamins and minerals per calorie. Because the study was small and cross-sectional, this is a moderate-confidence recommendation supported by early evidence rather than a settled conclusion. Individuals with specific concerns about vitamin D or vitamin E should discuss testing and supplements with a healthcare provider.
This research is most relevant to adults living with chronic spinal cord injuries, their caregivers, and healthcare teams, including dietitians, physicians, and rehabilitation specialists. It may also interest researchers studying nutrition for people with limited mobility. People without spinal cord injuries will find the general message useful, that eating less can make nutrient targets harder to meet, but this study’s specific advice is not designed for them. Anyone with kidney disease, diabetes, or other conditions that affect diet should speak with a clinician before making changes.
Changes to diet quality and nutrient intake can often be noticed within a few weeks of consistent changes, such as adding nutrient-rich foods to meals. Changes in blood levels of nutrients like vitamin D may take several weeks to months to show up on testing. Benefits for energy, digestion, and overall well-being vary from person to person, so setting realistic goals and reviewing progress with a healthcare provider every few months is a good approach.
Frequently Asked Questions
Do adults with spinal cord injuries get enough nutrients?
Many may not. A 2026 study found that adults with chronic spinal cord injury had lower nutrient levels overall, and more than 90% fell below the threshold for vitamin D and vitamin E. Their lower calorie intake appears to be the main reason for these gaps.
Why do people with spinal cord injuries have lower nutrient intake?
Research suggests that people with spinal cord injuries often eat about 34% fewer calories than others. Once that lower energy intake was accounted for, their diet quality and nutrient density looked similar, pointing to smaller food volume as the main factor.
What foods help people with spinal cord injuries get more nutrients from less food?
Nutrient-dense foods such as fatty fish, eggs, fortified cereals, nuts, leafy greens, and fruits provide more vitamins and minerals per calorie. A registered dietitian can help choose options that fit individual needs and preferences.
Is diet quality worse for people with spinal cord injuries?
Not clearly. A 2026 study found that Healthy Eating Index scores were similar between adults with spinal cord injury and matched controls. Both groups showed room for dietary improvement, particularly in nutrient-rich food choices.
Want to Apply This Research?
- Track daily calorie intake and the number of servings from key food groups, such as vegetables, fruits, dairy or fortified alternatives, and protein sources. Also log meals rich in vitamin D and vitamin E, such as fatty fish, fortified foods, nuts, and seeds. Aim to record at least five days per week, and review the weekly totals to spot patterns.
- Use the app to plan smaller meals that are packed with nutrients, such as adding spinach to eggs, choosing fortified cereal, or including a serving of salmon or nuts. Set a reminder to include one nutrient-dense food at each meal, and check the app’s nutrient summary before choosing snacks.
- Review nutrient and calorie trends monthly, and share summaries with a registered dietitian or physician at routine checkups. Repeat a three-day food record every few months to track progress, and consider blood tests for vitamin D and other nutrients when a clinician recommends them. Over time, look for steady improvements in nutrient density rather than focusing only on calorie totals.
This article summarizes a single cross-sectional study with a small sample, which cannot prove cause and effect. It is for general information only and is not medical or nutritional advice. People living with a spinal cord injury should talk with a doctor or registered dietitian before changing their diet, starting supplements, or making decisions about vitamin testing.
