When it comes to Lime, how do you classify them? Is it a ‘true’ fruit or just a vegetable? Here’s a quick answer according to Science Direct and Healthline:
Lime (citrus aurantiifolia)is classified as a fruit because it has seeds inside and grows within the branches of a lime tree. Lime fruits are acidic, juicy, and has an orange color. It’s an edible fruit, providing a variety of health benefits.
Lime is actually the result of growing Citrus aurantifolia, also known as a Key Lime Tree, which produces green globes that are about 2 inches in diameter. They are smaller than common limes and have a stronger flavor.
Limes get their characteristic sour taste from citric acid and can be eaten whole because the juice and flesh contain very few to no seeds at all.
As citric acid does not break down significantly during cooking, most cooked dishes use lemon instead of lime.
Classifying limes

Lemons and limes belong to different taxonomic groups: lemons to the family Rutaceae and limes to the family Rutaceae, so lime is technically a citrus fruit.
However, limes are usually treated as a separate food item from lemons for culinary purposes.
In the United States, limes are widely used in cuisine and beverages as an ingredient or as garnish. The sour flavor of limes complements fish and other seafood better than lemon juice does.
Lime juice is also commonly served with red-colored dishes to enhance their appearance due to the coloring compound found in most types of red fruits which are called lycopene.
Unlike lemons, limes do not tend to react with metal utensils and can be cut into wedges or processed into slices more easily. Lemons on the other hand produce more citric acid compared to limes so they can last longer than limes.
It depends on how the lime is used whether it is considered a fruit or vegetable. While lemons and limes are both members of the citrus family, they are different types of citrus fruit.
Limes tend to be sourer than lemons and can take on other flavors better as well.
Although lemon juice tastes better with certain foods, lime juice has been found to complement seafood dishes much better due to its coloring effects from lycopene.
Are Lemons and Limes in the Same Class?
Lemons and limes belong to two separate classes of fruit but are very closely related genetically.
One does not spoil faster than another, but lemons tend to hold out longer during storage compared to limes because of their higher citric acid content. The reason limes tend to be sourer is because they contain less flesh and pulp than lemons do.
Lemons and limes are both citruses but the fruit is not the same. Limes can be used in a variety of dishes, such as cocktails and seafood recipes, while lemons are generally used for baking or in drinks.

Lemons also hold out longer during storage compared to limes because of their higher citric acid content which helps them last up to two weeks while limes only last about half that time.
Lemons have a stronger taste than limes due to their higher citric acid content so they are better used in cooking while lime juice is more commonly served with red- foods to enhance their color due to their lycopene content.
Limes are better used in cooking while lemons are better for recipes due to their higher citric acid content which helps them last up to two weeks while limes only last about half that time.
It is ambiguous whether limes are considered fruits or vegetables. Limes can be used in a variety of dishes, such as cocktails and seafood recipes, while lemons are generally used for baking or in drinks.
Lemons have a stronger taste than limes so they are better used in cooking while lime juice is more commonly served with red- foods to enhance their color due to their lycopene content.
The correct answer is ambiguous because it depends on how the lime is used whether it is considered a fruit or vegetable.
Although lemons and limes are both members of the citrus family, they are different types of citrus fruit. Limes tend to be sourer than lemons and can take on other flavors better as well.
While lemon juice tastes better with certain foods, lime juice has been found to complement seafood dishes much better due to its coloring effects from lycopene.
Limes grow on a small evergreen tree and have been used as medicine for many years to treat scurvy, an illness caused by a deficiency of vitamin C.
They are also believed to have been used as a cleaning agent in the past as they contain citric acid which can be derived from lime juice, and therefore provides a powerful cleaning solution that is very acidic.
Vegetables can come from plants in several different ways
The plant may bear edible parts such as roots (carrots), stems (celery), tubers (potatoes), leaves (lettuce, spinach), flowers (broccoli, cauliflower), and fruits (tomatoes); Or the edible part may be produced by an accessory organ such as the root crown in carrots or apical meristems in edible palms like coconut.
Some vegetables like onions and garlic grow underground and much of what is eaten comes from storage organs, so they are classified as root vegetables; Although seeds of the plant may be eaten (like peas or green beans), most vegetable consumption is made up of fruits.
Further adding to the evidence when you cut open a lime its flesh will be green in color, indicating it has chlorophyll-producing capabilities. Chlorophyll is commonly associated with vegetables, as most are green in color because of the chlorophyll they contain.
However not all fruit are juicy and have fleshy exteriors. Take lemons for example, their rinds are so thick that you can’t even bite into them properly. Due to this fact, they’re sometimes referred to as “obligate drupes”.
This means they have a tough exterior that resembles bark-like skin around an actual pit/seed inside (unlike other fruits such as limes). Since lemons aren’t fruity enough to be considered fruits, why should we consider limes as one?
We must look at the bigger picture here. In terms of food classifications, our definition should be flexible. If we strictly followed the criteria for fruit/vegetable, then it would mean a lot of common items such as bananas and corn would have to be reclassified. Here’s a brief comparison:
Fruits Vegetables | Juicy exterior | Dry exterior | Small tree-like plant |
Vine-like plant | Seeds inside | Needs pollination | Many seeds inside |
With this in mind, let’s compare limes with lemons again. Despite being less juicy than other citrus fruits, both can be recognized as their own types of fruits due to one huge factor: they’re from different plants. This is extremely important because technically all fruit is developed from plants, even if by very different means.
Even though lemons and limes begin their lives on separate trees, their developmental stages are similar enough to be regarded as fruits (developed from fertilized flowers). For example, both of them contain seeds inside which grow into new plants.
However, since they developed on separate trees, it creates two unique fruit/plants that we may refer to as “lemons” or “limes”. On one hand, you have the lemon tree, which has several types of fruits including limes (and many other “intermediate” variations); all developed separately but related through propagation.
This is why technically speaking you could call either lime or a lemon under the right circumstances. Now I know a lot of this has been rather technical so far, but the real question is whether or not limes should be considered vegetables.
The answer to this question is no. Despite being used as a staple ingredient in many dishes across the world, limes are just as much a fruit as they are a vegetable.
In terms of their usage and origin, lemons and other citrus fruits have more in common with vegetables than actual fruit such as apples and oranges. This distinction may seem minor at first glance but it’s extremely important from a nutritional standpoint for those who eat healthily.
Limes contain essential nutrients which come from sugar and vitamins found within their juices (if you squeeze them open). Vegetables on the other hand, while containing nutrients do not offer any sugars or calories to the human body.
In terms of fruit vs. vegetable, limes fit into the former category rather than the latter because it contains many nutritional benefits that vegetables lack. For example, they contain a decent amount of vitamin C and potassium, which help promote proper health within our bodies.
Ultimately both fruits and vegetables have their own unique benefits to offer so there’s no reason why we should put them in one group or another through a rigid classification system.
By being more flexible with our definition from above, we can properly compare foods such as limes against each other instead of grouping them together arbitrarily. However, just remember that if you plan on eating healthy then you need to choose your fruits and vegetables wisely.

Conclusion
Limes are citrus fruits with many vitamins and minerals. They’ve also been touted for their antioxidant content.
Vegetables can include legumes like peanuts and soybeans, but they’re actually considered to be the fruit of the legume plant.
Some foods that are often considered to be vegetables, such as cucumbers, eggplants, and tomatoes, are botanically fruits because they develop from the ovaries of female flowers.
While there’s no question that limes come from a tree or bush and contain seeds, because much of the lime is eaten in its entirety, they are considered to be fruit.
