Is Sugar in Fruit Bad for You?

Fruits are called nature’s candy for a reason: They are our largest source of sugar in minimally processed whole foods. So when the low-carb diet gained popularity, fruit came under scrutiny by scrupulous dieters looking for a nutritional edge. We know fruit is a good source of valuable vitamins and minerals, but many people wonder: Is sugar in fruit bad for you?

In short, no, you probably shouldn’t eliminate that daily banana. Read on to get a better understanding of the sugar in your fruit and whether not it might be a concern for you.

Is Sugar in Fruit the Same as Regular Sugar?

The sticky sweetness you enjoy from a crisp apple comes from fructose, the main (but not the only) sugar in fruits. Fruits contain a combination of sugars — for example, an apple contains 6 percent fructose and 3 percent sucrose by weight. Sucrose is what we commonly know as table sugar, and it’s made up of fructose and glucose units (molecules) joined together.

Once eaten, you can digest both sucrose and fructose into glucose, which your brain uses as fuel — and glucose is what ends up in your bloodstream and raises your blood sugar. While sucrose can quickly be digested into glucose to spike that blood sugar, fructose is more complicated. Pure fructose doesn’t raise blood sugar very much, making it a popular sweetener for diabetics. Of course, that doesn’t give it a free pass.

Can You Eat Too Much Sugar from Fruit?

Researchers like Dr. Robert Lustig associate fructose to “alcohol without the buzz.” The basic argument: Glucose can be used by any tissue in the body, but only the liver is responsible for processing fructose — which, remember, is the main source of sugar in fruit.

When faced with fructose, the liver has two choices: It can convert fructose into glucose to fuel other tissues, or it can convert the fructose into fat and store it. If you regularly eat more than enough calories, guess what choice your liver makes? That’s right; it will store excess fructose as fat. This isn’t good because over time, this fat can accumulate in the liver and drive up your risk for insulin resistance and type 2 diabetes.

 

When Should You Avoid Eating Fruit?

The evidence against fructose collected by well-intentioned researchers like Dr. Lustig is partly why you may encounter sugar-phobic folks. But keep in mind that even Dr. Lustig, who goes on record calling sugar “toxic,” told the New York Times he wouldn’t advise cutting out fruit.

Basically, if you’re concerned about your sugar intake, you may want to consider avoiding fruit when it’s been highly processed — that apple juice isn’t the same as eating an apple, and you may not be getting the same ratio of beneficial fiber compared to the apple. Also, be wary of dried fruit. Dried fruit does contain fiber, but at a much lower volume, which makes overeating a more likely prospect.

Can Eating Fruit Help with Weight Loss?

If you’re a healthy person who wants to lose a few pounds and shape up, don’t ditch fruit from your diet just because it contains sugar. Because fresh fruit is loaded with fiber, eating fruit can help your weight-loss efforts by increasing satiety and balancing blood sugar.

Is Sugar in Fruit Bad for You?

Yes, experts do want you to consume less sugar, but you should strive to slash added sugar, not the naturally occurring sugars from fruit and dairy. Instead of axing fruit, try cutting down on sugary beverages such as sodas, lattes, energy drinks, and sports drinks, as well as refined carbohydrates such as cookies, cakes, and candies. Compared to some of these sugar bombs, fruit’s sugar content doesn’t come close — and it’s real, nutritionally superior food.
