I don't have a citation either, but google search reveals the following points:

1) One serving, or one medium apple, provides about 95 calories, 0 gram fat, 1 gram protein, 25 grams carbohydrate, 19 grams sugar (naturally occurring), and 3 grams fiber. 2) Recommended amount of consumed sugar for an adult is 30 grams per day. 3) You can also find a lot of citations how increased sugar consumption increases chances of diabetes.

So two apples already gets you above the recommended amount. An apple is basically 80% sugar in terms of calories: 19 * 4 / 95 = ~80%

Your comment is misleading. About point no. 2, that’s the recommended amount of added sugar, not counting fruits.

There are no studies to my knowledge that show increasing fruit intake increases chances of diabetes. But there are studies that show that the risk of diabetes goes down by increasing fruit intake.

To my understanding, that included fruit sugar, not only added sugar:

https://www.nhs.uk/live-well/eat-well/food-types/how-does-su...

> The government recommends that free sugars – sugars added to food or drinks, and sugars found naturally in honey, syrups, and unsweetened fruit and vegetable juices, smoothies and purées – should not make up more than 5% of the energy (calories) you get from food and drink each day.

But even if the recommendation is added sugar -- what is the real difference between added and "natural" occurring sugar? Does this distinction invalidate my comment above? The point being that it's quite possible and even easy to consume several times, or even order above the reasonable amount of sugar by eating fruits. The apple is not even the sweetest one.
