You’re standing in the produce aisle or maybe looking at a tree in your backyard, staring at a fruit that looks like a cross between a mango and a bloated banana. It’s a pawpaw. Or maybe you're in Australia or the Caribbean, where "pawpaw" is actually what Americans call papaya. This distinction matters. It matters a lot because if we're talking about the glycemic index of pawpaw, we have to first decide which plant is actually on your plate. Most of the global data focuses on the tropical Carica papaya, but the North American Asimina triloba is a different beast entirely.
Sugar is the enemy lately. Everyone’s checking their monitors.
Is this thing going to spike your insulin? Honestly, it’s complicated. The glycemic index of pawpaw (the tropical variety) typically sits around 58 to 60. In the world of nutrition, that puts it firmly in the "medium" category. It’s not a leaf of kale, but it’s certainly not a doughnut either. But GI numbers are often misleading because they don't account for how much you're actually eating in a sitting.
The GI vs. GL Debate: Why 58 Isn't a Scary Number
When you look at the glycemic index of pawpaw, you see that 58. By definition, anything below 55 is "low," and anything above 70 is "high." So, pawpaw is a bit of a middle child. It’s right on the edge. But here is the kicker: the Glycemic Load (GL) of a standard serving of pawpaw is usually around 5 to 9.
The Glycemic Load is what actually impacts your life. While GI tells you how fast the carbs turn into glucose, GL tells you how much glucose you're actually getting per serving. Because pawpaws—especially the tropical papaya types—are mostly water and fiber, the actual "sugar hit" your liver has to deal with is relatively small. You'd have to eat a massive amount of the fruit to cause the kind of metabolic chaos people fear.
If you are looking at the North American pawpaw, the data is scarcer. These are much denser, creamier fruits. They have a custard-like texture that hints at a higher fat and protein content than your average berry. Dr. Kirk Pomper from Kentucky State University, who is basically the leading authority on the Asimina triloba, has noted its rich nutrient profile. While a formal, massive-scale clinical trial for its exact GI hasn't hit the mainstream journals yet, its high fiber and fatty acid content suggest it might actually behave more like a complex carb than a simple sugar bomb.

Fiber: The Brake Pedal for Blood Sugar
Fiber is the hero here.
Without fiber, fruit is just nature’s soda. But the glycemic index of pawpaw stays moderate because of the structural makeup of the fruit. Tropical pawpaw is loaded with papain, an enzyme that helps with digestion, but it's the pectin and cellulose that slow down the absorption of fructose. When you eat the fruit whole, your body has to work. It has to break down those cell walls. This isn't juice.
Think about the texture. It’s slippery. It’s soft. That softness comes from soluble fiber. This type of fiber turns into a gel-like substance in your gut, which basically acts as a physical barrier, preventing sugar molecules from rushing into your bloodstream all at once. It’s the difference between a flood and a leaky faucet.
Real World Factors: Ripeness Changes Everything
A green pawpaw and a mushy, spotted pawpaw are not the same food. This is where people get tripped up. As a fruit ripens, its starches convert into simple sugars.
If you eat a pawpaw that is just barely ripe, the glycemic index of pawpaw will be on the lower end of that medium scale. If you wait until it’s so ripe it’s practically falling apart, those sugars are fully "unlocked." For a diabetic or someone managing insulin resistance, that window of ripeness is the difference between a stable afternoon and a shaky "sugar crash" two hours later.

- Under-ripe: Higher starch, lower GI, firmer texture.
- Perfectly ripe: Balanced sweetness, GI around 58.
- Over-ripe: High sugar concentration, potentially higher GI impact.
Don't let the fruit get too funky if you're watching your levels.
What the Research Actually Says
We should look at the work of researchers like Fiona Atkinson and Jennie Brand-Miller from the University of Sydney. They’ve spent decades cataloging these numbers. In their international tables, "Papaya, raw" (the tropical pawpaw) consistently lands in that 55-60 range.
There's also some interesting evidence regarding the antioxidant properties. A study published in the Journal of Medicinal Food suggested that the fermented version of this fruit could actually improve glycemic control in people with pre-diabetes. Now, that's not an excuse to go eat a pawpaw pie, but it shows that the fruit contains bioactive compounds—like flavonoids and polyphenols—that might help the body process glucose more efficiently. It’s not just about the sugar; it’s about the "packaging" the sugar comes in.
How to Eat Pawpaw Without Spiking Your Sugar
If you’re worried about the glycemic index of pawpaw, don't eat it in isolation. This is the golden rule of metabolic health.
Eat it with a fat or a protein.

Scoop your pawpaw into some full-fat Greek yogurt. Or maybe eat a handful of walnuts right after. The fat and protein further slow down gastric emptying. This means the food stays in your stomach longer, and the sugar enters the small intestine even more slowly. It’s a simple "hack" that turns a medium-GI food into a low-impact snack.
Also, watch the portions. A cup of cubed fruit is plenty. People get into trouble when they treat fruit like an all-you-can-eat buffet. Even low-GI foods will spike your sugar if you eat enough of them. Volume matters.
The "Other" Pawpaw: A Note for Americans
For those in the Eastern U.S. foraging for the North American pawpaw, remember that this fruit is incredibly nutrient-dense. It’s got more iron, magnesium, and copper than apples or grapes. Because it’s so rich—often described as a mix between a banana and a custard apple—you usually feel full much faster than you would eating watery tropical fruit. This "satiety factor" is a natural defense against overeating, which indirectly helps manage your glycemic load.
Actionable Steps for Managing Blood Sugar with Pawpaw
If you want to include this fruit in your diet without sabotaging your health goals, follow these specific strategies:
- Prioritize Texture: Choose fruit that is firm to the touch. If it’s turning into mush, the sugars are at their peak.
- The "Pairing" Rule: Never eat pawpaw on an empty stomach by itself. Always pair it with a source of healthy fat like avocado, nuts, or seeds to flatten the glucose curve.
- Timing Matters: Eat your fruit after a meal containing fiber and protein. The "food order" (veggies first, protein second, carbs last) has been shown in various studies to significantly reduce post-meal glucose spikes.
- Avoid the Juice: Never drink pawpaw juice. Removing the fiber turns a manageable glycemic index of pawpaw into a high-speed sugar delivery system that bypasses your body's natural filters.
- Monitor Your Response: Everyone’s microbiome is different. If you have a continuous glucose monitor (CGM), test how you react to a 100g serving. You might find you handle it better than someone else.
The reality is that pawpaw is a nutrient powerhouse. It's full of Vitamin C, Vitamin A, and folate. Avoiding it entirely because of a "medium" GI score is usually unnecessary for most people. It’s about being smart with the "how" and "when" rather than just the "what." Use the fruit as a dessert replacement or a nutrient-dense breakfast topper, and you'll likely find it fits perfectly into a balanced, health-conscious lifestyle.
Expert Insight: If you are specifically using the tropical variety for digestive help, the papain enzyme is most concentrated in the fruit just before it becomes fully ripe. This is also the point where the glycemic index of pawpaw is at its lowest, making it the "sweet spot" for both gut health and blood sugar management.
