The 12 Best Low-Sugar Fruits for Snacking, According to a Dietician

By: Emma Singer
Published: February 22, 2023

It’s news to no one that eating fruit is good for your health. That said, if you’re concerned with your sugar intake—be it because of diabetes or some other reason—not all fruits are created equal. For this reason, we spoke to a registered dietician to get some top picks for low-sugar fruits that won’t spike your blood glucose levels.

Before you start snacking on mother nature’s candy, though, the expert says there are a couple other things to keep in mind—namely that when it comes to blood sugar levels, it’s always best to opt for the whole fruit instead of just drinking its juice, and that even low-sugar fruits can impact glucose levels when consumed as “naked carbs” (i.e., all by their lonesome), which is why you’d be wise to pair fruit with a protein or healthy fat whenever possible.

Meet the Expert

Alyssa Wilson is a registered dietician whose experience includes serving as a nutrition coach at a major gym, leading nutrition programs in corporate wellness and, currently, working as a Metabolic Success Coach with Signos.

How Much Sugar Should You Aim for in a Day?

When it comes to selecting low-sugar foods, a little context in the form of recommended daily intake (RDI) can be very helpful. So how much sugar are you actually supposed to be consuming anyway? Well, friends, the answer is a bit more complicated than you think—namely because the only hard and fast recommendations you’ll find relate to added sugars, which are far worse for your health than the nutritionally beneficial, natural sugars found in whole, raw fruits. 

According to the 2015-2020 Dietary Guidelines for Americans, no more than 10 percent of your daily caloric intake should come from added sugars (so, 200 calories or 50 grams of sugar per day on a 2,000 calorie per day diet). The American Heart Association has more conservative guidelines—recommending an upper limit of 100 calories or 24 grams of added sugar per day for most women.

As previously mentioned, the natural sugars found in fruit are a very different story, and there are no upper limits on their consumption—namely because they are often good sources of dietary fiber and nutrients, and are processed by the body very differently than added sugars. As such, aim to eat natural sugars in place of added sugars whenever you can and know that you needn’t worry about eating fruit because, though it is technically possible to get too much of a good thing, the experts at WebMD say you'd have to try really hard to achieve a problematic level of sugar consumption from fruit alone. 

The takeaway? Steer clear of added sugar, but don’t sweat the natural stuff found in fruits and veggies. And if you have diabetes, remember that the most important thing is to monitor your blood glucose levels according to your doctor’s instructions, because those can be influenced by a variety of foods (including fruit) and they’re a very big deal for your health.

1. Strawberries

Amount of Sugar: 7 grams per cup

In addition to being an excellent low-sugar option, strawberries can raise good cholesterol and reduce blood pressure, and just one cup of the whole fruit provides your recommended daily dose of Vitamin C.

2. Raspberries

Amount of Sugar: 5.4 grams per cup

Wilson tells us that berries are one of the best low-sugar fruits you can eat in general, but if we’re talking about specific types of berries, raspberries have the lowest sugar with a mere 5 grams per cup.

2. Grapefruit

Amount of Sugar: 10.6 grams per half fruit

Grapefruits are known for being tart, so it should come as no surprise that one half of this (quite large) fruit has only roughly 11 grams of sugar. Best of all, grapefruit can help keep insulin levels even, thus reducing the risk of type 2 diabetes.

3. Kiwis

Technically considered a berry, one kiwi—which are easy to find all year—has just about 7 grams of sugar. This fruit is also an excellent source of Vitamin E, which helps protect the skin from sun damage.

4. Avocado

Amount of Sugar:  1 gram per avocado

Avocados are as close to sugar-free as a fruit can be (and yes, they are technically fruits). An entire avocado has only 1 gram of sugar, along with the added benefit of being packed with healthy fats.

6. Peaches

Amount of Sugar: 12.6 grams per fruit

While a perfectly ripe peach does indeed taste quite sweet, the average peach only has about 13 grams of sugar. Peaches are also full of Vitamins C, B2 and A, as well as iron and antioxidants.

7. Plums

Amount of Sugar: 6.6 grams per fruit

With only 30 calories and roughly 7 grams of sugar, plums are the perfect low-sugar fruit to add to salads and desserts for a little sweetness. Plums are also rich in fiber, which helps slow down a blood sugar spike after you eat carbs.

Amount of Sugar: 12.6 grams per cup

Clocking in at just under 13 grams per cup of cubed fruit, cantaloupe is relatively low in sugar and fairly low in carbs, since it is 90 percent water. Cantaloupe is also a great source of Vitamin A.

Amount of Sugar: 13.8 grams per fruit

Known for being high in Vitamin C, a navel orange has around 70 calories and less than 14 grams of sugar. Oranges help your body absorb iron, while also boosting your immune system.

10. Asian Pears

Amount of Sugar: 8.6 grams per fruit

Pears are a tasty fruit composed of mostly water and relatively little sugar. Asian pears are a particularly good choice, since they contain only about 9 grams of sugar, which is less than a regular pear, and boast the satisfying crunch of an apple.

11. Lemons and Limes

Amount of Sugar: 2.1 grams per lemon; 1.1 grams per lime

With only about 2 grams and 1 gram of sugar, respectively, lemons and limes are perfect to add to a glass of water. Plus, both these citrus fruits are loaded with Vitamin C, which can reduce your risk of stroke and heart disease.

12. Cucumbers
