Fruit is often considered a healthy and nutritious part of a well-balanced diet. However, when it comes to the ketogenic diet, or “keto” diet for short, fruit may not be as beneficial as it seems.
One of the main reasons why fruit may not be as healthy as it is perceived to be is its high carbohydrate and sugar content. Half of the sugar found in fruit is fructose, a type of simple sugar that can be harmful to human health in excess.
Fructose is processed by the liver, and when consumed in large amounts, it can lead to a build-up of fat in the liver, leading to non-alcoholic fatty liver disease. Excess fructose consumption has also been linked to an increased risk of developing insulin resistance, a precursor to type 2 diabetes.
While all fruits contain some amount of fructose, some popular options like bananas, apples, and mangos contain higher amounts of carbohydrates and sugar compared to others. For example, a medium-sized banana contains 27 grams of carbs and 14 grams of sugar, while a medium-sized apple contains 25 grams of carbs and 19 grams of sugar. In comparison, a cup of blackberries contains 7 grams of carbs and 4 grams of sugar.
It’s important to note that while ancient humans did consume fruit, it was not in the same quantities as we do today. In the past, fruit was seasonal and not as readily available as it is now. Additionally, the fruit of the past was not genetically modified to be as large and sweet as the fruit we have today.
Berries, such as blueberries and blackberries, are a healthier choice for those following a keto diet due to their lower carbohydrate and sugar content. They are also a good source of vitamins and antioxidants. It’s always a good idea to choose a variety of low-carb fruits to ensure you are getting a diverse range of nutrients.
In conclusion, while fruit is a nutritious addition to any diet, it is important to be mindful of its carbohydrate and sugar content, especially when following a keto diet. Excess fructose consumption has been linked to negative health consequences, and it is important to consume fruit in moderation. Berries, such as blueberries and blackberries, are a healthier choice due to their lower carbohydrate and sugar content and are a good source of vitamins and antioxidants. As with any dietary change, it is important to consult with a healthcare professional before making any significant changes to your diet.
