What If I Told You You Can Have Unlimited Fruit?
Bananas, mangoes and grapes included. Let’s talk about fruit, blood sugar and finally making peace with your fruit bowl.
For this October newsletter, I’ve decided to let the cat out of the bag. Or, more appropriately, let the banana out of the nutritional interrogation room.
Somewhere along the way, fruit became suspicious.
I see patients who have stopped eating it altogether because “it’s a carb.” Others have insulin resistance, prediabetes or type 2 diabetes and have been told to avoid fruit, or stick exclusively to berries. Meanwhile, whole oranges, orange juice and dried cranberries somehow end up in the same nutritional bucket.
So let’s pull up a chair and untangle this together.
As a Registered Dietitian and Certified Diabetes Educator, I consider the research on carbohydrate digestion and absorption, post-meal glucose responses, insulin sensitivity, appetite regulation, energy balance and body composition. But I also consider something equally practical: how these recommendations fit into your everyday life.
And here is what I want you to know:
You can enjoy fruit. Yes, even a banana.
First, about that word “unlimited”!
Do I mean unlimited quantities, all day, regardless of your appetite, blood sugar or nutritional needs? No.
I mean an unlimited invitation to explore different types of fruit, without a tiny “approved fruit” list.
Peaches. Plums. Mangoes. Cherries. Apples. Pears. Kiwi. Pineapple. Grapes. And, of course, berries.
Having diabetes does not automatically put these foods off limits. Fruit contains carbohydrate, so portions and how you distribute it throughout the day still matter. But carbohydrate content is a reason to personalize your plan, not automatically eliminate fruit.
My practical starting point for many clients is two to three portions of whole fruit across the day, adjusted to their needs. A fist-sized piece or roughly 1 cup of cut fruit can be a useful visual guide.
One important detail: this is a visual guide, not a carbohydrate-counting rule. A cup of grapes and a cup of strawberries contain different amounts of carbohydrate. If you count carbohydrates or use mealtime insulin, your portions need more individual attention.
The goal is nourishment and flexibility. No fruit spreadsheet required.
Why I want more variety in your fruit bowl?
Different fruits bring different combinations of fibre, vitamins, minerals and beneficial plant compounds. Variety gives you more opportunities to enjoy those nutrients, rather than relying on one “perfect” fruit.
There is also the very practical matter of what tastes good, what is available and what fits your budget.
If pears are in season, enjoy pears. If frozen mango is on sale, put it in your cart. If you have been dreaming about a juicy peach, you do not need to negotiate with a raspberry first.
Fresh and unsweetened frozen fruit are both good options. Frozen fruit is especially handy when fresh produce is expensive or your week gets busy.
A positive relationship with food includes room for preference, pleasure and practicality.
Fruit and blood sugar: what the glycemic index actually tells us.
The glycemic index, or GI, compares the blood glucose response to foods containing the same amount of available carbohydrate, usually 50 grams, against a reference food.
The usual categories are:
Low GI: 55 or less
Medium GI: 56–69
High GI: 70 or more
Here is the catch: GI testing does not compare the portions you necessarily eat at home. It also does not give a food a complete nutritional report card.
Glycemic load adds another piece of information by accounting for the amount of carbohydrate in a portion. Both can be useful, but neither replaces looking at your overall meal and individual response.
Yes, there are far more low-GI fruits than berries.
Diabetes Canada’s guide places the following fresh fruits in its low-GI category. This is a practical reference list, rather than an exhaustive list of every tested variety:
Fruit family | Low-GI options in the guide |
Orchard favourites | Apples, pears, peaches, plums, nectarines, fresh apricots and fresh cherries |
Citrus | Oranges, mandarins, grapefruit and pomelo |
Berries | Berries, including strawberries, blueberries, raspberries and blackberries |
Tropical choices | Mango, kiwi, guava, passionfruit, papaya and starfruit |
More variety | Pomegranate, fresh figs, cantaloupe and honeydew |
Bananas | Green or unripe bananas |
Its medium-GI category includes grapes, pineapple, ripe yellow bananas, watermelon, fresh lychee, jackfruit and persimmons. Brown, overripe bananas appear in its high-GI category.
However, a fruit does not have one permanent GI score. Variety, ripeness and testing methods can change the result. The University of Sydney database even includes an overripe banana tested at 57, in the medium range. That is why I would not claim that all overripe bananas are high GI, or that they are the only fruit that can test high.
Make fruit part of something satisfying.
One of my favourite ways to build a satisfying snack is to pair fruit with a protein-rich food, nuts or seeds.
Try:
Cherries and almonds: About a cup of cherries with a small handful of almonds.
Mango and Greek yogurt: Frozen mango with ¾ cup plain Greek yogurt and cinnamon.
Orange and egg: Orange slices alongside a hard-boiled egg.
Pear and cottage cheese: Sweet, creamy and wonderfully simple.
Apple and nut butter: A familiar combination for a reason.
Peaches and yogurt: Fresh or thawed peaches spooned over plain yogurt.
Adding protein or fat can slow digestion and change the timing of the blood glucose response. It may also help a snack keep you satisfied for longer. It does not cancel the carbohydrate or guarantee a flat glucose curve.
And please hear this: you can still eat a piece of fruit on its own. Pairing is a useful option, not another rule you have to follow perfectly.
Before blaming the grapes, look at the rest of your day.
You open the fridge, find the grapes and suddenly realize you have been standing there eating them for ten minutes.
Before putting grapes on trial, get curious:
Did I eat enough today?
Did I skip lunch?
Have I had anything satisfying since breakfast?
Am I hungry, tired, distracted, or simply enjoying something delicious?
In my practice, I often help clients build a predictable eating rhythm. For some, that means eating within one to two hours of waking and planning meals or snacks roughly every three to four hours.
That is a practical strategy we personalize, not a universal metabolic requirement. Your medication, activity, appetite and schedule all matter.
For meals and snacks, the divided plate offers a simple starting point:
½ your plate: Vegetables and / or fruit.
¼ your plate: Protein, such as fish, chicken, tofu, legumes or eggs.
¼ your plate: Starch (optional), such as potatoes, brown rice or quinoa.
Your overall eating pattern deserves more attention than one bowl of pineapple.
Whole fruit versus fruit juice: where fibre enters the conversation!
Let’s talk about a dietitian’s favourite F-word.
Fibre. Obviously.
Whole fruit brings fibre, water and some chewing time. Juice generally contains much less fibre and is easy to drink quickly, which makes it a different experience for fullness and blood glucose.
That does not make 100% fruit juice “just sugar.” It still provides nutrients. But it is not nutritionally interchangeable with eating the whole fruit, and portions matter.
My everyday preference? Eat the orange instead of drinking it.
Blending whole fruit keeps the fibre in the recipe, provided you do not strain it out. Still, a smoothie can pack several portions into one glass. Think about the amount of fruit you add, and build a satisfying combination with foods such as plain Greek yogurt or unsweetened soy milk.
Whole, sliced, mashed or blended: the preparation can vary. The portion and overall combination still count.
Dried fruit: still fruit, just a smaller portion.
Dried fruit deserves some nuance, too.
Removing water makes fruit more concentrated. You can fit much more fruit, carbohydrate and energy into a small handful. But drying fruit does not turn its sugars into starch or make it stop being fruit. It still provides fibre and other nutrients.
My approach is to use smaller portions and check for added sugar.
Enjoy dried cranberries in your salad. You do not automatically have to remove every crouton or spoonful of quinoa. Instead, consider how those carbohydrate foods fit together in the portions you enjoy.
The lesson is portion awareness, not another food "rule".
Our community challenge: bring fruit back to the table.
This month, I would love us to practise something together:
More variety. More nourishment. Less fruit 'worry'.
If it fits your individual nutrition plan, try including two to three portions of whole fruit across your day. Use a fist-sized piece or about 1 cup of cut fruit as a starting visual, adjusting portions when you need to account for carbohydrate.
Try pairing at least one with a protein-rich food, nuts or seeds. Then notice:
Did you enjoy it?
Did you pair it with a protein +/- healthy fat?
How did your energy and hunger feel afterwards?
Show me your fruit. Show me your pairing. Tell me how you felt.

I would love to see your combinations, from a beautifully arranged fruit yogurt bowl to apple slices dipped in cinnamon cottage cheese.
We are building everyday habits here. No food styling required.
And if you have spent years worrying about whether a banana belongs in your day, let this be an invitation to reconsider that rule with kindness.
You deserve a way of eating that supports your health and a positive relationship with food. There is room for both.
Warmly,

Eat the Rainbow Fruit Salad
A little sweet, a little tangy, and a whole lot of colour.
Makes: Approximately 8 cups
Prep time: 25 minutes
Ingredients
1 cup strawberries, hulled
½ cup blackberries
2 kiwis, peeled
2 mandarins, peeled and separated into segments
1 cup peeled mango
1 cup peeled pineapple
1 medium apple, cored, skin left on
1 cup seedless grapes
½ cup pomegranate arils
½ cup blueberries
Lime-honey dressing
3 tablespoons fresh lime juice
1 teaspoon finely grated lime zest
1–2 teaspoons honey, to taste, optional
Instructions
Prep the fruit. Wash and thoroughly dry the fruit. Chop the strawberries, blackberries, kiwis, mandarin segments, mango, pineapple, apple and grapes into small, roughly dime-sized pieces. Halve larger blueberries; leave small blueberries and pomegranate arils whole.
Make the dressing. Whisk together the lime juice, lime zest and honey, if using.
Toss gently. Add all the fruit to a large bowl, pour over the dressing and gently fold until evenly coated.
Serve. Enjoy immediately, or refrigerate for 15–30 minutes before serving so the flavours can mingle.
Make it your own: Swap in finely chopped peaches, nectarines, pears, plums or pitted cherries. Use what is in season, on sale or already in your fridge.
Fridge life: Refrigerate promptly in an airtight container and enjoy within 2 days for the best texture. The fruit will soften and release juice as it sits, so gently stir before serving.
