While the benefits of consuming fruits and vegetables are widely recognized, there's a growing understanding of the unique advantages of vegetables. Despite this knowledge, vegetable intake often remains low. This article explores effective strategies to increase vegetable consumption and highlights the specific health benefits associated with a vegetable-rich diet.
The Distinct Benefits of Vegetables
Although fruits and vegetables both offer health advantages due to their bioactive compounds like vitamins, minerals, and antioxidants, they differ significantly in their composition and impact. Fruits generally contain more dietary sugars, which can affect health and consumer choices. Vegetables, on the other hand, often have more protein and fiber. The way we process vegetables before eating can also change how our bodies use the nutrients in them, affecting their health benefits.
Studies show that fruits and vegetables have different effects on health. Fruits are usually sweet and eaten raw as snacks or desserts. Vegetables can be bitter, are often cooked, and are eaten as part of meals with other foods. This means that different things affect how much fruit and vegetables people eat. One study found that people didn't eat fruit because it cost too much, they didn't like it, it wasn't good quality, it wasn't available, or it went to waste. They didn't eat vegetables because they didn't like them, they didn't have time, they cost too much, or they didn't like the taste.
Even though people around the world don't eat enough fruits and vegetables, efforts to get them to eat more often focus on fruit and have more success with fruit than with vegetables. This shows that we need different ways to get people to eat more fruits and vegetables, and especially ways to get them to eat more vegetables.
Eating lots of vegetables on their own, not just with fruits, has specific health benefits. Studies have found that it can lower the risk of heart disease, type II diabetes, non-gallstone-related acute pancreatitis, some cancers, and cognitive decline. Reviews of studies have also shown that eating more vegetables is linked to a lower risk of stroke, dementia, cognitive decline, and some cancers. However, the evidence for cancer prevention is not always consistent. Some studies have also linked specific types of vegetables, like dark green leafy vegetables and cruciferous vegetables, to better health results.

Most studies don't look at eating vegetables separately from eating fruits or other foods. Since people often eat fruits and vegetables together, the benefits might be because of eating more produce in general or having a healthier diet and lifestyle, not just from eating vegetables.
Barriers to Vegetable Consumption
Research suggests several reasons why people don't eat enough vegetables. Young children often dislike the bitter taste of vegetables, and they may be afraid to try new foods. Older children continue to avoid vegetables due to taste and appearance, but family habits also play a role. Families with less education and money, parents who don't eat many vegetables, limited availability of vegetables, negative views of vegetables at home, and a lack of support for eating vegetables are less likely to consume them.
Adolescents' vegetable consumption is similarly affected by socioeconomic status, parental habits, and family environment, but their own thoughts and beliefs also become important. Adults who eat more vegetables tend to like the taste of vegetables, value health and healthy eating, have good cooking and food knowledge, eat regular meals, cook at home, and avoid fast food. Since childhood eating habits often continue into adulthood, it's important to encourage vegetable consumption early in life.
Effective Strategies to Increase Vegetable Intake
Given the multifaceted reasons behind low vegetable consumption, a range of strategies is needed to address these barriers. These strategies can be broadly categorized based on the factors they target: hedonic (taste, liking, familiarity), environmental, and cognitive.
Modifying Hedonic Factors
- Taste and Flavor Enhancement: Experiment with different cooking methods (roasting, grilling, sautéing) and seasonings to make vegetables more palatable. Roasting vegetables, for instance, can caramelize their natural sugars, creating a more appealing flavor.
- Pairing with Familiar Foods: Introduce vegetables alongside familiar and liked foods. This can make vegetables more approachable and increase their acceptance.
- Repeated Exposure: Offer vegetables repeatedly, even if they are initially rejected. Repeated exposure can increase familiarity and liking over time. Remy et al. found that repeated exposure to a target vegetable puree, sometimes paired with a sweetener, could influence intake.
- Masking Undesirable Tastes: Use sauces or disguise vegetables in composite dishes to dilute negative tastes and appearances.
Altering Environmental Factors
- Increase Availability and Accessibility: Ensure vegetables are readily available and easily accessible at home, school, and workplaces. Keep pre-cut vegetables in the refrigerator for quick snacks.
- Parental/Caregiver Modeling: Parents and caregivers should model healthy eating habits by consuming vegetables themselves. Children are more likely to eat vegetables if they see their parents enjoying them.
- Create a Supportive Family Environment: Encourage vegetable consumption through positive reinforcement and avoid pressuring children to eat.
- Home Cooking: Prepare home-cooked meals more often to accommodate individual preferences and incorporate more vegetables into dishes.
- Community Gardens: Community garden programs can increase vegetable consumption.
- Reduce Salt and Fat Provision: Bouhlal et al. found that reducing salt and fat provision can impact vegetable consumption.
Addressing Cognitive Factors
- Nutrition Education: Provide education on the health benefits of vegetables and how to prepare them in appealing ways.
- Culinary Skills Training: Teach individuals how to cook and prepare vegetables in a variety of ways.
- Goal Setting: Encourage individuals to set realistic goals for increasing their vegetable intake.
- Action Planning: Help individuals develop specific plans for incorporating more vegetables into their daily meals.
Multi-Component Interventions
Many successful interventions combine strategies targeting multiple factors. For instance, the "High 5 for Kids" program used tailored newsletters, home visits, and materials for parents and children, targeting knowledge, parental modeling, feeding practices, and vegetable availability.
