What we have on our plates can sometimes be quite deceptive. That “vegetable” you’ve been adding to your stir-fry could very well be a fruit in disguise. 

You heard that right! 

The culinary world and science have different take on classifying certain foods. With “18 Fruits That Are Commonly Mistaken for Vegetables,” we aim to debunk some popular misconceptions and provide enlightening insights into these unexpected food categories. But why does this confusion even exist, and how can we differentiate between fruits and vegetables more accurately?

In this blog post, we will demystify these ambiguities and provide you with a list of 18 fruits you’ve likely been identifying as vegetables all this time. The objective is simple: to help you understand the fascinating world of fruits and vegetables better, and maybe even surprise you a bit along the way. After all, aren’t the best learning experiences often filled with unexpected revelations?

What is Technically a Fruit?

In our everyday conversations, we tend to refer to sweet, natural, juicy foods as “fruits”, right? However, a fruit’s technical definition, from a botanical perspective, is quite different. 

Have you ever wondered about this?

Let’s delve into the world of botany for a moment. Technically, a fruit is the mature ovary of a flowering plant, usually containing seeds. This definition might sound complicated, but in simple terms, if it grows from a flower and seed, it’s scientifically classified as a fruit.

Surprised?

Let’s take this one step further. Fruits can be categorized into three main types: simple, aggregate, and multiple. Simple fruits, like peaches or avocados, develop from a single ovary of a single flower. Aggregate fruits, like strawberries, form from many ovaries of a single flower. Finally, multiple fruits, such as pineapples, develop from many ovaries of many flowers. Each of these fruit types exhibits unique characteristics and growth patterns.

But the question lingers, why are some fruits frequently mistaken for vegetables? 

This discrepancy mainly stems from the culinary world. Chefs often classify fruits and vegetables based on flavor profiles and usage in different recipes, rather than botanical properties. Thus, fruits that are less sweet and more versatile in savory dishes—like tomatoes or zucchini—are commonly labeled as vegetables in the kitchen. 

It’s no wonder that many of us get tripped up!

What is Technically a Vegetable?

In the previous section, we highlighted how fruits, from a scientific viewpoint, are defined. Now, let’s pivot and consider their often-confused counterparts – vegetables. 

How do we define a vegetable, and why are there persistent mix-ups between fruits and vegetables?

Botanically a vegetable is generally any vegetative non-reproductive part of a plant that is consumed by humans as food as part of a savory meal. Which is not a mature ovary or a fruit. It includes a wide variety of plant parts, ranging from leaves (like spinach), and roots (like carrots), to stems (like asparagus), and more.

From a culinary perspective, vegetables are typically less sweet than fruits and are used predominantly in savory dishes. Unlike fruits, which are generally determined by a standard botanical definition, vegetables are more loosely classified based on culinary usage and cultural traditions.

But, why are some vegetables often mistaken for fruits? 

This confusion arises when we consider plants that are technically fruits by botanical standards, but due to their flavor profile and culinary usage, are typically considered vegetables. 

Think about tomatoes or bell peppers. They aren’t sweet, are they? 

They lend themselves to salads, stir-fries, and other savory dishes. Therefore, in the kitchen, they’re often treated as vegetables.

Can you imagine stirring diced apples into your pasta sauce or grilling slices of pear on the barbecue alongside your bell peppers? It doesn’t quite fit, does it? 

This culinary context is the root cause of the perplexity surrounding fruits and vegetables.

List of 18 Fruits That You Think Are Vegetables

Now that we’ve uncovered the technical definitions of fruits and vegetables let’s dive into the heart of this discussion. 

Here are 18 fruits that, due to their characteristics and culinary usage, you might have been assuming were vegetables. Brace yourself, some might truly surprise you!

1. Tomatoes

A popularly common ingredient used in different recipes worldwide, the tomato, teeming with vitamins A and C, is technically a fruit with seeds inside them. It’s culinary versatility and savory flavor profile has granted it the status of a vegetable in the kitchen.

Interestingly, in the 1893 U.S. Supreme Court case Nix v. Hedden, tomatoes were legally defined as vegetables, primarily for taxation purposes.

2. Cucumbers

FAQs

Can a fruit be a vegetable at the same time?

While the botanical definition of fruits and vegetables is distinct, in culinary terms, there can be overlap. Many botanical fruits like tomatoes, cucumbers, and peppers are treated as vegetables in the kitchen due to their taste and usage in recipes. So, in a culinary sense, they can be considered both.

Is it true that bananas are berries?

Yes, surprisingly, bananas are technically berries. A berry is a fleshy fruit that comes from a single ovary of a flower and has seeds inside. So, botanically speaking, bananas fit the description of a berry.

Why are some fruits sweet and others not?

The sweetness in fruits comes from natural sugars that develop as the fruit grows and matures. The level of sweetness can vary based on a variety of factors, including the type of fruit, the specific variety, and how ripe the fruit is. Some fruits, like berries and melons, tend to be sweeter, while others, like avocados and tomatoes, are less so.

Are all nuts and seeds fruits?

Not all seeds and nuts are fruits, but many are. Botanically speaking, fruits develop from the ovary of a flower and contain seeds. So, seeds are a part of the fruit, but they aren’t fruits themselves. As for nuts, while culinary nuts like almonds are seeds, true nuts, like acorns, are indeed fruits.

Are mushrooms considered vegetables?

While mushrooms are often found in the produce section and used like vegetables in cooking, they are actually a type of fungi and not classified as either a fruit or vegetable botanically.
