15 Best Low-Carb Fruits & Vegetables

by John Staughton (BASc, BFA) last updated -

For people looking to improve their overall health, low-carb fruits and vegetables are a great way to cut down on overall carbohydrate intake. They are also known to offer a variety of health benefits. Carbohydrates are the main source of energy required by the body and are considered one of the 3 key areas of our diet, in addition to protein and fat. In fact, most nutrition experts recommend that people consume between 35-65% of your daily calories from carbohydrates.

However, not all carbohydrates are created equal; some are more complex and take more time for the body to digest. Whereas others are simple carbs, which you might get from white bread, fruit and dairy products. When you consume an excess of simple carbohydrates (sugars), the body will begin to store those extra carbs as fat. [1]

There are other side effects of consuming too many carbohydrates, including digestive issues, particularly if the carbohydrates are all fiber-rich. Furthermore, simple carbohydrates lead to spikes in blood sugar, as the body quickly processes them into usable glucose but it can be difficult for the pancreas to create enough insulin in response.

A low-carb diet is also known as a ketogenic diet and has become quite popular in recent years, and low-carb fruits and vegetables are a great way to succeed in this dietary effort. A Harvard Health Publishing report suggests that consuming fewer carbs can also help to curb your hunger pangs, boost cognition, lower your risk of certain cancers and improve your overall cardiovascular health.
