A recent study published in Nutrients reveals that a significant number of plant-based offerings at both omnivore (OMNI) and vegan or vegetarian (VEG) restaurants worldwide are far from healthful. The study, which analyzed restaurant menus across 37 countries, found that many plant-based dishes include unhealthy ingredients such as refined grains, deep-fried foods, and saturated fats—components known to increase the risk of chronic diseases like heart disease and diabetes.
The researchers discovered that 14% to 27% of restaurants did not offer any healthful plant-based main courses at all. Only 2% of the eateries analyzed achieved a perfect health score, meaning nearly all plant-based menus contained at least one unhealthy ingredient. This finding raises concerns about the quality of plant-based dining options and the potential health risks they pose.
Rise in Plant-Based Diets, But Health Concerns Remain
The increasing popularity of plant-based diets is evident, with many individuals choosing to reduce or eliminate animal-based products for health, environmental, or ethical reasons. Projections suggest that the U.S. vegan market will grow by 12% annually until 2030. While dairy and meat alternatives are becoming more accessible, a significant portion of consumers—about 63%—are not fully vegan or vegetarian but are simply incorporating more plant-based foods into their diets.
Despite the growing trend, experts caution that not all plant-based foods are beneficial. Items such as fried foods, sugary snacks, and refined grains, common in many plant-based dishes, can contribute to poor health outcomes. Refined grains, for instance, are linked to an increased risk of coronary heart disease, hypertension, and type 2 diabetes. The American College of Cardiology and the American Heart Association recommend limiting foods high in refined grains, saturated fats, and added sugars—categories that frequently appear in plant-based restaurant offerings.
The Study Methodology
Over three years, the researchers visited 561 eateries in 196 cities across six continents, focusing on those that offered vegan options. These included both OMNI and VEG establishments, with the majority of restaurants located in the U.S. (373), followed by Australia and several European countries. Menus were reviewed for plant-based main courses, and restaurants were classified based on the number of healthful dishes they offered. Dishes were considered healthful if they lacked refined grains, deep-fried ingredients, and saturated fats.
Restaurants were scored on a scale from 0 to 10, with one point awarded for each healthful dish. The analysis found that while U.S. restaurants offered slightly more healthful options than those abroad, the difference was minimal. On average, U.S.-based restaurants featured 6.6 plant-based main courses compared to 6.2 in non-U.S. eateries.
Key Findings
The study revealed concerning trends about the nutritional quality of plant-based offerings:
-
Refined Grains: 40% of OMNI and 38% of VEG meals included refined grains like white rice, white flour, and refined pasta. These ingredients are associated with adverse health outcomes, including increased mortality.
-
Health Scores: Only 2% of restaurants received a perfect score, indicating they offered plant-based dishes free from deep-fried ingredients, saturated fats, and refined grains. Conversely, 26% of OMNI and 14% of VEG restaurants scored zero, largely due to the presence of refined grains and other unhealthy ingredients.
-
Nutritional Transparency: Just 33 restaurants (6%) provided full nutritional details online. These restaurants, most of which were OMNI establishments, adhered to U.S. Food and Drug Administration (FDA) regulations requiring franchises with 20 or more locations to disclose calorie counts, sodium, sugar, and saturated fat content.
-
Menu Variety: OMNI restaurants averaged 4.5 vegan main courses, while VEG restaurants featured 8.4. However, only 59% of VEG eateries and 16% of OMNI eateries offered a full vegan menu, meaning the remaining restaurants typically offered a limited selection of plant-based items.
Conclusions and Recommendations
The study highlights a troubling gap in the availability of truly healthful plant-based options. While VEG restaurants generally offered a higher proportion of healthy dishes, refined grains were the most common issue in both OMNI and VEG establishments. Furthermore, nutritional transparency remains a significant challenge. Only a small number of restaurants provide the necessary information for customers to make informed dietary choices.
Researchers argue that the findings have important policy implications, particularly in light of the strong connection between poor diets and chronic diseases. They suggest that regulatory bodies like the FDA should consider expanding nutritional disclosure requirements to include smaller restaurants and not just large franchises.
Restaurants, while not solely responsible for their customers’ health, can play a crucial role in reducing health risks by limiting the use of harmful ingredients like refined grains, excessive sodium, and unhealthy fats. Encouraging more transparency and promoting healthier menu options could help patrons make better dietary choices and reduce the long-term burden of diet-related diseases.
While this study offers valuable insights into the global state of plant-based restaurant offerings, it also faces limitations. The sample primarily consisted of U.S. and Westernized countries, and assessments were based on online menu descriptions, which may not capture all the nutritional details of the dishes. Despite these limitations, the research underscores the need for greater attention to the nutritional quality of plant-based dining options and the importance of providing consumers with the information they need to make healthier choices.
