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) (opens in new tab). 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 (opens in new tab), 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 (opens in new tab). 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.
