Hospitals can successfully serve plant-based meals that provide adequate protein and taste good, according to a 2025 multidisciplinary study published in the European Journal of Nutrition. Researchers developed 30 plant-based recipes organized into seven daily menus that deliver 90-97 grams of protein per day using soy, lentils, grains, and nuts, costing €10.50 to €12.30 daily. Gram Research analysis confirms these meals are nutritionally complete, palatable, and cost-effective, making them practical for hospital implementation while supporting sustainable food policies.
Hospitals are trying to serve more plant-based meals to help the environment, but they struggled to make them taste good and have enough protein. Researchers worked with hospital staff and food companies to create 30 new plant-based meal recipes that taste great and provide all the protein patients need. The meals use ingredients like soy, lentils, grains, and nuts, and cost between €10.50 and €12.30 per day. According to Gram Research analysis, these meals prove that hospitals can successfully switch to more plant-based options without sacrificing nutrition or taste.
Key Statistics
A 2025 multidisciplinary study published in the European Journal of Nutrition developed 30 plant-based meal recipes that provide 90-97 grams of protein per day, meeting hospital patient nutritional needs at a cost of €10.50 to €12.30 per person daily.
Researchers incorporated pea protein isolate and soy-based drinks into plant-based hospital meals to increase breakfast and lunch protein content without enlarging portion sizes, addressing a key barrier to hospital adoption of plant-based options.
Plant-derived hospital meals developed through co-creative testing with hospital staff and industry partners demonstrated that fully plant-based menus can achieve nutritional adequacy, palatability, and cost-effectiveness suitable for clinical use.
The Quick Take
- What they studied: Can hospitals create plant-based meals that taste good, have enough protein, and fit their budgets?
- Who participated: Hospital staff, food industry partners, and nutrition experts worked together from April to December 2025 to develop and test the meals
- Key finding: Researchers successfully created 30 plant-based meal recipes organized into 7 daily menus that provide 90-97 grams of protein per day—enough for hospital patients—while staying affordable at €10.50 to €12.30 per day
- What it means for you: If you eat hospital meals or care about environmental sustainability, hospitals may soon offer more plant-based options that are just as nutritious and tasty as traditional meals. However, hospitals will need to balance protein quality, taste, cost, and portion sizes when implementing these meals.
The Research Details
This was a collaborative research project where hospital workers, nutrition experts, and food companies worked together to create new meals. The team started by identifying what makes a good hospital meal based on medical guidelines and hospital policies. They then created 30 different plant-based recipes and tested them through cooking and tasting sessions, getting feedback from the people who would actually eat them.
After each tasting session, the recipes were adjusted to improve flavor and texture. The researchers then calculated the nutritional content of each meal using a detailed food database and checked whether the meals provided complete proteins (all the amino acids your body needs). They also tracked the cost of each meal to make sure hospitals could afford to serve them.
The final step was organizing the 30 recipes into seven different daily menus so hospital patients would have variety throughout the week while getting consistent nutrition.
This research approach matters because it involves the actual people who will use these meals—hospital staff and patients—rather than just scientists working in a lab. When real users help design food, the meals are more likely to be eaten and accepted. The study also checks multiple important factors at once: nutrition, taste, cost, and whether hospitals can actually prepare these meals with their existing equipment and staff.
This study has several strengths: it involved multiple experts from different fields (nutrition, cooking, hospital management), it tested meals through actual tasting sessions rather than just computer calculations, and it addressed practical concerns like cost and kitchen feasibility. However, the study doesn’t specify how many people tasted and evaluated the meals, which would help us understand how representative the feedback was. The research was conducted in one country (Netherlands) using local food databases, so results may vary in other regions with different food availability and costs.
What the Results Show
The research team successfully developed 30 plant-based meal recipes that were organized into seven complete daily menus. These menus provided between 90-97 grams of protein per day, which meets the protein needs of most hospital patients. The main protein sources were soy products, lentils, grains (like rice and wheat), and nuts—all plant-based foods that provide complete amino acids.
One key challenge was making sure breakfast and lunch had enough protein without making portions too large. The team solved this by adding pea protein isolate (a concentrated plant protein powder) and soy-based drinks to these meals. This allowed them to increase protein content without requiring patients to eat significantly larger portions.
The daily cost of these plant-based menus ranged from €10.50 to €12.30 per person, which is competitive with traditional hospital meal costs. The meals were designed to be prepared in standard hospital kitchens using equipment that already exists in most hospitals.
The research identified important trade-offs that hospitals need to consider. While the meals met protein requirements, achieving the highest quality protein (with all amino acids in ideal proportions) sometimes required using more expensive ingredients or larger portions. The team found that taste preferences varied, meaning some patients preferred certain plant-based meals over others. The study also showed that using a variety of protein sources—mixing soy, lentils, grains, and nuts—helped create meals that were both nutritionally complete and flavorful.
Previous research has shown that plant-based diets can be healthy, but hospitals have struggled to implement them because of concerns about protein adequacy and patient acceptance. This study builds on that knowledge by actually creating practical meal plans and testing them with real people. Unlike previous studies that focused only on nutrition calculations, this research included taste testing and cost analysis, making it more applicable to real hospital settings. The finding that plant-based hospital meals can be cost-competitive is particularly important, as cost has been a major barrier to adoption.
The study doesn’t clearly report how many people participated in the tasting sessions or how diverse their backgrounds were, which limits our understanding of whether these meals would appeal to all patient populations. The research was conducted in the Netherlands using Dutch food databases and prices, so the costs and available ingredients may differ significantly in other countries. The study doesn’t follow patients over time to see if they actually eat these meals when served in real hospitals or whether they remain satisfied with them long-term. Additionally, the research doesn’t address potential allergies or cultural food preferences that might affect patient acceptance in diverse hospital populations.
The Bottom Line
Hospitals interested in serving more plant-based meals should consider using this research as a blueprint. The evidence strongly supports that plant-based hospital meals can provide adequate protein and be cost-effective. However, hospitals should expect to spend time testing recipes with their own staff and patients, as taste preferences vary. Start by introducing a few plant-based options alongside traditional meals rather than switching completely. Work with your kitchen staff to ensure they’re comfortable preparing these meals, and consider adding protein-rich ingredients like soy drinks or pea protein powder to breakfast and lunch items. (Confidence level: Moderate to High—the research is well-designed but limited to one country and doesn’t include long-term patient follow-up.)
Hospital administrators and nutrition directors should care about this research because it provides a practical roadmap for implementing sustainable food policies. Patients with environmental concerns or those who prefer plant-based diets will benefit from more options. Healthcare workers concerned about the environmental impact of food production should support these initiatives. However, patients with specific protein needs (such as those recovering from surgery) should discuss their individual requirements with their healthcare provider, as hospital meals need to be customized to medical conditions.
Hospitals can implement these meals relatively quickly—within weeks to a few months—since the recipes are already developed and tested. However, expect a transition period of 2-3 months as kitchen staff learn new recipes and patients adjust to different flavors. Benefits like reduced environmental impact would be immediate, while long-term health benefits would depend on individual patient factors and overall diet quality.
