The 15 Best Low-Sugar Fruits for Snacking, According to a Dietician

It shouldn’t be news that eating fruit is good for your health. That said, if you’re concerned with your sugar intake—be it because of diabetes, a low-carb diet or another reason—not all fruits are created equal. For this reason, we spoke to two registered dietitians to get their top picks for low-sugar fruits that won’t spike your blood glucose levels, plus tips for managing your sugar intake.

• 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 health coach with Signos.
• Dr. Felicia Stoler, DCN, is a registered dietitian, nutritionist and exercise physiologist. She’s the author of Living Skinny in Fat Genes: The Healthy Way to Lose Weight and Feel Great and the former host of TLC’s Honey, We’re Killing the Kids.

The TLDR? Berries, apples, citrus fruit, avocado, stone fruit and melons are all fair game. That means apricots, oranges, pears and beyond are all on the menu.

In addition to sugar content, it’s important to take glycemic index—a tool used to manage blood sugar—into account, especially if you have diabetes or are an athlete. According to Harvard Health Publishing, "The glycemic index is a value assigned to foods based on how quickly and how high those foods cause increases in blood glucose levels. Foods low on the glycemic index (GI) scale tend to release glucose slowly and steadily. Foods high on the glycemic index release glucose rapidly." (Stoler adds that the comparative benchmark for glycemic index is a slice of white bread, which has a GI of 100.)

In addition, high GI foods (above 70) help boost energy after a workout, making them good for, say, long-distance runners or marathoners, while low GI foods (55 and under) can inspire weight loss. Also note that a food's glycemic index can change based on how it’s prepared, what it's served with, its ripeness and how it’s been processed.

Before you start snacking on nature’s candy, Wilson 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 drinking its juice, and that even low-sugar fruits can impact glucose levels when consumed as “naked carbs” (meaning all by their lonesome), which is why it’s wise to pair fruit with a protein or healthy fat whenever possible. Stoler stresses the importance of pairing fruit with fiber-rich foods as well; as your body digests soluble fiber, it lowers the GI of other foods.

The answer is a bit complicated, 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 restrictive 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 different story, and there are no upper limits on their consumption—namely because they’re often good sources of dietary fiber and nutrients and processed by the body very differently than added sugars.

The takeaway? Aim to eat natural sugars instead of added refined sugars whenever you can, and know that you needn’t worry about eating fruit because. Though it's technically possible to eat 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.

Of course if you have diabetes, remember that the most important thing is to monitor your blood glucose levels according to your doctor’s instructions, because they can be influenced by a variety of foods, including fruit.
