The pervasiveness of added sugar in our diets is linked to an increased risk of obesity, diabetes, heart disease, and stroke. But in the epic rush to avoid sugar, many health-conscious consumers and low-carb dieters are starting to avoid eating fruits because it contains natural sugar. Despite containing sugar, fruits are a part of a healthy diet when eaten in the right portions.
Is the sugar in fruit the same as added sugar?
Superficially, it could make sense; if you were to look at certain fruits’ nutrition labels, they may boast over 20 grams of sugar.
But this sugar isn’t the same as the kind that’s used in candy bars and ice cream. Isabel Smith, MS, RD, CDN, founder of Isabel Smith Nutrition, and New York City-based celebrity dietitian and fitness expert, weighs in: “It’s key to look at added sugars differently than sugar in fruit.”
“In fruit, we’re getting so much more nutrition [compared to refined sugar],” she adds. Fruit also comes with free-radical-fighting antioxidants, vitamins, minerals, phytochemicals, water, and fiber. This total package is what makes eating fruit so good for you.
Is fruit sugar good for you?
Countless studies have found that increased fruit consumption, regardless of the fruit’s sugar content, is tied to lower body weight and a lower risk of obesity-associated diseases.
Experts believe it’s because when you eat whole fruits, you’re also getting plenty of fiber. And this fiber helps you feel full while slowing the digestion of the fruit’s sugar (which keeps your blood sugar from spiking).
On the other hand, refined sugars are just empty carbs that lack these healthy nutrients, which is the reason why they’re metabolized quickly, lack the ability to make you feel full, and contribute to weight gain.
Is too much fruit sugar bad for you?
The old adage is still true: too much of anything isn’t a good thing.While there are many benefits of eating fruit, “we still want to be mindful of how much fruit we’re eating because it does contain sugar,” explains Smith.
It’s not “added sugar,” but the sugar in fruit can still have the same blood-sugar-spiking effect if eaten in excess.
How many servings of fruit should you eat per day?
Smith usually recommends getting in 2-3 servings of fruit per day, and keeping it to a serving at a time.
And yes, that goes for smoothies as well. “Smoothies can be large whacks of carbs and sugar, especially if there’s no protein or healthy fat that acts similarly to fiber to slow digestion and prevent blood sugar from spiking,” she says.
As far as sugary fruits go? You can still eat the exceptionally sweet ones, but Smith recommends you eat these in smaller portions and pair them with extra fiber, a healthy fat like peanut butter, or protein such as a scoop of plant-based protein powder or Greek yogurt to slow digestion and blunt the sugar spike.
5 Lowest-Sugar Fruits
Only five fruits have less than 10 grams of sugar in a one-cup serving.
1. Cranberries: 4.3 g sugar (1 cup, whole)
2. Raspberries: 5.4 g sugar (1 cup, whole)
3. Blackberries: 7.0 g sugar (1 cup, whole)
4. Strawberries: 7.4 g sugar (1 cup, halves)
5. Watermelon: 9.4 g sugar (1 cup, diced)
These low-sugar fruits all have less than 15 grams of sugar per one-cup serving of raw fruit.

Cranberries are so low in sugar that when the FDA proposed requiring food labels to list added sugar as a separate category from sugar, Ocean Spray (the cranberry juice company) wrote a letter requesting exemption because, “cranberries … are naturally low in sugar, giving them a distinctly tart, astringent, and even unpalatable taste.” (And yes, that is a direct quote from their official letter to the FDA.) Yep. Ocean Spray basically said that cranberries need sugar to taste good. But they don’t! Eat them without the sugar in an antioxidant-packed oatmeal bowl. Create a one cup serving of mixed fruits—cranberries, apples, and blueberries. Combine with walnuts and add to a bowl of oatmeal. In an American Chemical Society analysis of the cancer-fighting phenol antioxidant content of 20 fruits, cranberries were found to have the highest amount.

For being so high on our list, you’re probably wondering why watermelon gets a bad rap for being high in sugar. It could partly be because it tastes so sweet, and it’s low in slow-digesting fiber, causing it to rank high on the glycemic index; however, in reality, it has a very small impact on your blood sugar levels because it’s low in total carbs. Good news, because watermelon has some impressive health benefits: Research published in the Journal of Nutritional Biochemistry showed that eating watermelon may improve lipid profiles and lower fat accumulation. We’re looking forward to those summer watermelon-eating contests!

Pears are so sweet that it seems impossible they only contain about 100 calories each, but it’s true. This fall fruit is a good source of vitamin C and contains 6 grams of fiber per medium fruit (24% of your daily value). Pears help keep hunger at bay thanks to pectin, “a soluble fiber that attracts water and turns to gel, slowing down digestion,” says Jennifer Glockner, RDN, “which may help to reduce blood cholesterol and reduce the risk of heart disease and colon cancer.”

Bananas can help you sleep, build lean muscle, and burn fat, but compared to other fruits they’re pretty high in sugar and carbs, so no monkey business: stick to one five-inch portion a day. This ensures you’ll reap all the fruit’s benefits—without expanding your waistline.
Cassie Bjork, RD, LD, says, “I encourage consuming protein and healthy fat with the banana to slow down the absorption of the sugar from the banana into your bloodstream. This is the most effective strategy for keeping blood sugar levels stable, which means consistent energy levels and weight loss (since stable blood sugar levels allow the pancreas to secrete glucagon, the fat-burning hormone!)”

You can thank grapes’ sugar content for that pounding headache you get after downing a couple glasses of wine. And while both red and green grapes are high in sugar, they’re also rich in antioxidants. You may have heard that red wine is touted as a “healthy” alcoholic drink because of its resveratrol content—a plant compound that has been linked to improving heart health, burning fat, and boosting weight loss. But wine contains only a fraction of the resveratrol and other protective phenolic compounds found in grapes, so experts recommend the best way to boost your consumption of polyphenol compounds is by directly increasing fruit consumption.

No wonder pomegranate juice doesn’t need any added sweeteners. It’s sweet enough on its own! But it’s not just sugar pomegranates are high in; their arils (the seeds) are also pretty mighty when it comes to their nutrient content. Pomegranates contain three types of antioxidant polyphenols—including tannins, anthocyanins, and ellagic acid—which all help fight and prevent damage to your body caused by free radicals. One pomegranate also provides about 30 mg of vitamin C, which is important for skin and immune health. They have a fairly high fiber content, so as long as you stick to the serving size, don’t be afraid to pop the arils as a snack, sprinkle them onto salads, yogurt, or even on top of chicken dishes.

While you may only know this sweet fruit from its inclusion in the famous Fig Newton cookies, you’ll have to eat the fruit raw—and without the coating of sugar and flour—to best reap the health-protective benefits such as its high fiber, potassium, calcium, magnesium, and vitamins A, E, and K contents. Figs also contain prebiotics, which help support the pre-existing good bacteria in the gut, improving digestive wellness. But because of their high sugar content, be sure to enjoy by eating only one or two whole ones at a time. Try wrapping figs in prosciutto and adding a dollop of goat cheese. Both the meat and the cheese have extra protein to help fill you up so you don’t feel the need to keep munching.
