What Is Fruit?
According to botany (the study of plants) fruit is a seed-bearing structure that develops from the ovary of a flowering plant. It is usually sweet. Vegetables, on the other hand, are all other plant parts, such as roots, leaves and stems.
In the context of food, certain “vegetables,” like eggplant and bell peppers are actually fruits, and some foods, such as tomatoes, have properties of both fruits and vegetables. For this article, I use the term fruit to describe what you probably think of when someone says the word fruit (berries, apples, papaya, etc.), though technically speaking avocados, cucumbers, and olives are all fruit as well.
Where Does The “Fruit Makes You Fat” Idea Come From?
Many people who believe fruit makes you fat adhere to the principles of “broscience,” which Urban Dictionary accurately defines as “the predominant brand of reasoning in bodybuilding circles where the anecdotal reports of jacked dudes are considered more credible than scientific research.” In this case, while hearing what others have to say is generally a good thing, it’s important to understand that genetically gifted or “assisted” individuals often look the way they do in spite of their approach, not because of it.
Others believe the fructose (a type of sugar found in fruit) causes fat gain. Some studies suggest that fructose ingestion leads to insulin resistance, elevated blood cholesterol levels and increased fat gain, especially in the abdominal area.1Additionally, fructose lowers the amount of insulin released in response to meals. This in turn lowers the circulating levels of the hormone leptin, which is responsible for increasing feelings of fullness and raises the hunger-promoting hormone ghrelin.2 This scenario can lead to excess calorie consumption, which can cause fat gain.
