Fruit Sugar vs Added Sugar: Heart Surgeon Explains Why Whole Fruit Is Different

Fruit contains sugar. Desserts, soft drinks and processed snacks also contain sugar.
So are they really different?
According to cardiovascular surgeon Dr Jeremy London, the sugar molecules found in fruit and added sugar are chemically similar. But the body does not respond to an apple in the same way it responds to a glazed doughnut or sugary drink. (Hindustan Times)
The key difference is not simply the sugar itself.
It is what comes along with it.
“The Difference Is the Packaging”
Whole fruits contain fibre, water, vitamins, antioxidants, polyphenols and other micronutrients.
These components slow digestion and reduce the speed at which sugar enters the bloodstream. As a result, the blood-sugar rise may be slower than when the same amount of sugar is consumed in isolation. (Hindustan Times)
Added sugar in sweets, soft drinks and many processed foods usually comes without the same fibre, water and nutritional value.
That means it can be absorbed more quickly and may be easier to consume in large quantities.
Dr London explained that while an apple and a doughnut both contain sugar, their effect on digestion, fullness and overall metabolism can be very different. (Hindustan Times)
Why Whole Fruit Is Better
Whole fruit is generally more filling because it contains fibre and water.
This makes it harder to consume excessive amounts compared with sweetened drinks or highly processed snacks.
For example, eating several oranges takes time and provides fibre. Drinking a glass of orange juice can deliver the sugar from multiple oranges much more quickly, with far less fibre.
That is why Dr London emphasised the importance of choosing whole fruit rather than assuming every fruit-based product has the same health benefits. (Hindustan Times)
What About Fruit Juice?
Fruit juice may retain some vitamins, but much of the fibre is removed during processing.
Without that fibre, the sugar can be absorbed more rapidly, making juice behave more like a sugary drink than a whole fruit.
Even juices labelled “100% fruit juice” should therefore be consumed in moderation. (Hindustan Times)
What About Dried Fruit?
Dried fruit usually retains fibre, but most of its water has been removed.
This concentrates the sugar and calories into a smaller portion.
Because dried fruit is compact and easy to eat, people may consume much more sugar before feeling full compared with fresh fruit. (Hindustan Times)
The Bottom Line
Sugar is still sugar chemically.
But food cannot be judged by one ingredient alone.
The fibre, water and micronutrients found in whole fruit significantly change how it is digested and how filling it is.
The practical message is clear:
Choose whole fruit most often, limit added sugar and treat fruit juice and dried fruit as more concentrated options.
