Ripeness level: The riper a fruit is, the more starch it converts to sugar. It’s always best to eat it when it’s just ripe or slightly underripe.
What about watermelon?
The special case: Watermelon has a high glycemic index (GI), but a very low glycemic load (GL) because it contains a lot of water. The real problem is the quantity: it’s difficult to eat just a small portion. If you have self-control, you can eat it; otherwise, it’s best to avoid it.
Tips and recommendations:
Always prioritize whole fruit, never juice.
Respect portion sizes, even with “safe” fruits.
Avoid overripe fruit.
