When you’re managing type 2 diabetes, you’re often told to eat more fruits and vegetables.
That’s great advice, but it can also be confusing. Is all fruit created equal? The short answer is no.
While fruit is a natural and healthy source of vitamins, minerals, and fiber, some types can send your blood sugar on a rollercoaster ride.
This is because fruits contain natural sugars, and some pack a much bigger sugar punch than others.
Navigating the produce aisle doesn’t have to be stressful. The key is understanding which fruits are higher in sugar and how they might affect you.
This guide is here to help you identify some of the potential worst fruits for diabetes type 2, not to ban them forever, but to help you make more informed choices about portion sizes and frequency.
We’ll explore which fruits to be mindful of and, more importantly, how to enjoy fruit as part of a balanced, blood-sugar-friendly diet.
Smart Tools for a Diabetes-Friendly Kitchen
Making mindful choices is much easier when you’re set up for success. Having the right tools and products on hand can empower you to manage your diet effectively and enjoy your food without worry.
Here are some essentials that are incredibly helpful for anyone managing type 2 diabetes.

With these items in your arsenal, you’ll be better equipped to navigate your diabetes diet with confidence and ease. Now, let’s talk about those fruits.
Understanding the “Worst” Fruits for Diabetes Type 2
Before we list the fruits, it’s critical to understand what “worst” means in this context. No fruit is inherently “bad.”
However, some fruits have a higher glycemic index (GI) or are much denser in sugar and carbohydrates than others.
For someone managing type 2 diabetes, eating large portions of these fruits can cause a rapid and significant spike in blood sugar levels.
The key is mindfulness. This list highlights fruits that require extra attention to portion size.
1. Grapes
Grapes are a classic grab-and-go snack, but their small size makes it incredibly easy to overeat them.
You pop one in your mouth, then another, and before you know it, you’ve eaten a whole bunch. While they contain beneficial antioxidants, they are also little globes of sugar.
A single cup of grapes contains around 23 grams of sugar and 27 grams of carbohydrates.
Because they are mostly sugar and water with very little fiber to slow down digestion, they can cause a fast rise in blood glucose.
If you choose to eat grapes, portioning is essential. Don’t eat them straight from the bag. Instead, count out a small serving (about 1/2 cup or 15 grapes) and put the rest away.
A Better Approach:
- Pair a small portion of grapes with a source of protein and fat, like a handful of almonds or a piece of cheese. This combination helps slow the absorption of sugar and prevents a sharp spike.
2. Mangoes
Known as the “king of fruits,” mango is undeniably delicious, with a sweet, tropical, and creamy texture.
Unfortunately, that incredible sweetness comes from a high sugar content. A single cup of sliced mango can pack about 23 grams of sugar and 28 grams of carbs.
Mangoes have a moderate to high glycemic index, depending on their ripeness. The riper the mango, the higher its GI, meaning it will raise your blood sugar more quickly.
If you love mango, you don’t have to give it up entirely, but you must be strict with your portion size.
Stick to a small serving, like a half-cup of diced mango, and be sure to account for it in your daily carbohydrate count.
A Better Approach:
- Enjoy a few small cubes of mango as a topping for plain Greek yogurt. The protein in the yogurt will help buffer the sugar absorption.
- Avoid mango juice at all costs, as it’s a highly concentrated source of sugar without any of the fruit’s natural fiber.
3. Cherries
Cherries are another fruit that’s easy to eat by the handful. They are sweet, juicy, and satisfying, but like grapes, their sugar can add up quickly. A cup of pitted cherries contains roughly 20 grams of sugar.
While they are a good source of potassium and antioxidants like anthocyanins (which give them their deep red color), their sweetness means they need to be consumed with caution.
If you are sitting down with a bowl of cherries, it’s very easy to lose track of how many you’ve had. Always measure your portion first. A serving of about 1/2 cup (around 12-15 cherries) is a more manageable amount for most people with diabetes.
A Better Approach:
- Buy frozen cherries to use in smoothies. This forces you to measure them out and allows you to blend them with protein powder or spinach to create a more balanced meal.
4. Bananas
Bananas are convenient, inexpensive, and packed with potassium, but they are also one of the more carbohydrate-dense fruits. A medium-sized banana contains about 27 grams of carbs and 14 grams of sugar.
The ripeness of a banana also plays a significant role. An under-ripe, slightly green banana has more resistant starch and less sugar, so it has a lower glycemic index.
As a banana ripens and turns yellow with brown spots, the starch converts to sugar, making it sweeter and causing a faster blood sugar response.
If you eat bananas, opt for smaller ones and choose those that are still slightly green.
Eating a whole large, ripe banana can be equivalent to eating a sugary dessert for some individuals. A half-banana is often a more appropriate serving size.
A Better Approach:
- Slice half a small, greenish banana and add it to your oatmeal or pair it with a spoonful of peanut butter. The fat and protein in the peanut butter will help slow down the carb absorption.
5. Pineapple
The sweet, tangy, and tropical flavor of fresh pineapple is hard to resist. However, it’s another fruit that is high in natural sugars.
A cup of pineapple chunks contains over 16 grams of sugar and 22 grams of carbohydrates.
Fresh pineapple has a moderate GI, but canned pineapple, especially in heavy syrup, is one of the worst fruits for diabetes type 2 and should be avoided entirely.
The syrup adds a massive amount of refined sugar.
Even pineapple canned in its own juice is more concentrated in sugar than its fresh counterpart. If you must eat pineapple, stick to a small portion of the fresh fruit.
A Better Approach:
- Try grilling a thin slice of fresh pineapple. The grilling process caramelizes the sugars and brings out a rich flavor, so a small amount feels more satisfying. Serve it alongside grilled chicken or fish.
6. Dried Fruits (Raisins, Dates, Figs)
Dried fruit is perhaps the most deceptive of all. It’s often marketed as a healthy snack, but it is essentially fruit with all the water removed.
This process concentrates the sugar and calories into a much smaller, denser package.
Consider raisins. A cup of grapes has about 23 grams of sugar, but a cup of raisins has over 100 grams!
A small box of raisins, which seems like a tiny snack, can contain 25-30 grams of carbohydrates—the same as a couple of slices of bread.
Dates and dried figs are similarly high in sugar. Because they are so easy to overeat and cause a very rapid blood sugar spike, many nutritionists consider them among the worst fruits for diabetes type 2.
A Better Approach:
- If you must use dried fruit, use it very sparingly as a garnish, not a snack. For example, chop up one or two dates to add a touch of sweetness to a large salad or a bowl of oats.
7. Lychee
Lychees are a sweet, floral, and exotic treat, but they are another fruit high on the sugar scale.
A cup of lychees contains a hefty 29 grams of sugar. Their small size and unique texture make them very easy to eat in large quantities.
Like many of the other fruits on this list, they lack the fiber and protein needed to slow down the absorption of their sugar.
This means they can lead to a quick and significant increase in blood glucose levels, making them a fruit to eat with extreme caution and in very small, measured portions if at all.
A Better Approach:
- Enjoy two or three lychees as a special treat alongside a protein-rich snack. Or, slice one up and add it to a glass of sparkling water with a sprig of mint for a refreshing, low-impact drink.
8. Fruit Juice
While not a whole fruit, fruit juice deserves a special mention as the absolute worst offender.
When you juice a fruit, you strip away all of its beneficial dietary fiber. What’s left is essentially a glass of sugar water that will send your blood sugar soaring faster than almost any other food.
Even 100% pure fruit juice with “no added sugar” is still a highly concentrated source of the fruit’s natural sugar.
A small 8-ounce glass of orange juice can have as much sugar as a can of soda. The lack of fiber means there is nothing to slow down its absorption.
For this reason, all fruit juices should be strictly avoided or treated as a “treat” in a very small quantity.
A Better Approach:
- Eat the whole fruit instead! An entire orange has fiber that will help you feel full and slow down the sugar release. If you’re craving a drink, infuse water with slices of lemon, lime, or a few raspberries.

It’s About Balance, Not Banishment
Seeing this list of the worst fruits for diabetes type 2 might feel discouraging, but it shouldn’t.
The goal is not to eliminate these fruits from your life but to approach them with knowledge and mindfulness. Any fruit can fit into a healthy diabetes diet if the portion is small enough.
The best fruits for people with diabetes are generally those that are high in fiber and lower in sugar, such as berries, apples, and pears. But if you truly love mango or cherries, you can still enjoy them. The key is to:
- Control Your Portions: Use a food scale. A half-cup serving is a good starting point.
- Pair with Protein/Fat: Never eat high-sugar fruit by itself. Always pair it with nuts, seeds, cheese, or yogurt.
- Eat, Don’t Drink: Choose whole fruits over juices and dried fruits.
- Test Your Blood Sugar: See how these fruits affect you personally. Your meter is your best guide.
By making smart, informed choices, you can continue to enjoy the delicious world of fruit while keeping your blood sugar in check.
