What's the difference between fruit and vegetables? At a glance, the answer to this question may seem pretty simple. Obvious, even. If it's sweet and juicy like a strawberry, it must be a fruit. And if it's savoury and fibrous like a carrot, it must be a vegetable. But is that how these two food groups are officially defined? Or are there any other aspects that need to be taken into account?
You may have heard that some people consider tomato a fruit. But tomato can sometimes be categorized as a fruit, and sometimes as a vegetable. That's because the exact definitions will depend on whether you're a gardener or a chef, as explained by the European Food Information Council (EUFIC). Moreover, your language and country of origin may also affect how you perceive this issue.
Here, we will explain what constitutes a fruit, and what is considered to be a vegetable, according to different definitions. You may be surprised!
Most people will look at the issue from a culinary standpoint. In that case, fruits and vegetables are separated based on their taste and aroma. According to this definition, fruits are sweet or sour, while vegetables are more mild and savory. These two food groups will also have different culinary uses. Fruits will be predominantly added to desserts, smoothies or juices, while vegetables will form a part of a hearty side dish or the main course.
However, what constitutes fruit and vegetables will look completely different to a botanist. According to the book Postharvest Physiology and Biochemistry of Fruits and Vegetables, fruits are seed-bearing structures that develop from the ovary of a flowering plant.This means that 'vegetables' like tomatoes, cucumbers, peppers, squash, pumpkins, eggplants, corn kernels, and bean and pea pods are actually fruits. Whereas a vegetable is any edible part of a plant that doesn’t happen to be a fruit, as in leaves (spinach, lettuce, cabbage), roots (carrots, beets, turnips), stems (asparagus), tubers (potatoes), bulbs (onions), and flowers (cauliflower and broccoli).
How you perceive fruit and vegetables may also depend on where you're from and the language you speak. In 2011, the journal Public Health Nutrition published a survey that revealed the scope of these cultural differences. According to their findings, rice was considered to be a vegetable by 20% of adult respondents based in the US. When compared with English speakers, Spanish speakers were more likely to call rice a vegetable. On the other hand, Chinese speakers were less likely to do so. Beans, which are often grouped in the vegetable category, also divided opinions. Compared to Spanish speakers, English speakers were more likely to label them as vegetables.
Debate over the difference between fruit and vegetables can sometimes reach such a fever pitch that the law must step in. In the 1893 United States Supreme Court case Nix. v. Hedden, the court ruled unanimously that an imported tomato should be taxed as a vegetable, rather than as a (less taxed) fruit, as described in the Mercer Law Review. The court acknowledged that a tomato is a botanical fruit, but went with what they called the "ordinary" definitions of fruit and vegetable — the ones used in the kitchen.

I hold a BA (Hons) degree in journalism from the University of Stirling and have contributed to various publications, including Cardiff Times magazine, Psychology Now, and science bookazines. Additionally, my interest in the environment extends beyond writing, as I've worked with Operation Wallacea on rainforest and ocean conservation research.
Now, let's delve into the concepts presented in the article about the difference between fruit and vegetables. As an enthusiast with demonstrable knowledge, I'll provide insights into the various perspectives discussed in the article.
1. Culinary Definition: From a culinary standpoint, fruits and vegetables are distinguished by taste and aroma. Fruits, such as strawberries, are sweet or sour, while vegetables like carrots are more mild and savory. The culinary uses also differ, with fruits often added to desserts, smoothies, or juices, while vegetables form part of hearty side dishes or main courses.
2. Botanical Definition: According to botanists, fruits are seed-bearing structures that develop from the ovary of a flowering plant. This botanical definition includes items like tomatoes, cucumbers, peppers, squash, pumpkins, eggplants, corn kernels, and bean and pea pods as fruits. Vegetables, on the other hand, encompass edible parts of a plant that aren't fruits, such as leaves, roots, stems, tubers, bulbs, and flowers.
3. Cultural and Linguistic Influences: Cultural and linguistic factors also play a role in how people perceive fruits and vegetables. A 2011 survey highlighted cultural differences in categorizing foods, with variations among English, Spanish, and Chinese speakers. For instance, rice was considered a vegetable by 20% of adult respondents in the US, showcasing cultural diversity in food classification.
4. Legal Perspective: The article mentions a historical legal case, Nix v. Hedden (1893), where the US Supreme Court ruled that an imported tomato should be taxed as a vegetable, despite its botanical classification as a fruit. This decision reflected the "ordinary" definitions used in kitchens rather than botanical considerations.
These diverse perspectives illustrate the complexity of defining fruits and vegetables, encompassing culinary, botanical, cultural, linguistic, and legal dimensions. Understanding these nuances enhances our appreciation of the multifaceted nature of this seemingly straightforward culinary classification.
