ELI5: What is actually happening to fruit when it ripens? Does the calorie content increase while the fruit is sitting on the counter getting sweeter?
gpt
As fruit ripens, starch is being converted into glucose (bigger carbohydrate molecules to smaller ones). The more ripe it is, the more conentrated sugars there are(making it taste sweeter of course). So caloric value does not increase as carbohydrates are converted, rather than created.
