Sugar-free is seen as a sign of healthy living. However, fruits,  which used to be seen as healthy, has been unfairly treated like something bad. Now apples, berries, and oranges are looked at with doubt, almost like they’re the same as processed sugary snacks.

According to Harvard trained gastroenterologist Dr Saurabh Sethi, MD MPH, this is one of the most common misconceptions he encounters. “Whole fruit does not count as added sugar,” he explains in his recent Instagram post.

But  many people attempting sugar-free challenges cut out fruit entirely, believing fructose in fruit behaves the same way as refined sugar. “It doesn’t,” Dr Sethi stresses, adding, “That distinction matters more than people realise.”

The confusion, studies say, comes from oversimplifying sugar into a single category. Added sugars, those found in sweets, soft drinks and processed foods, enter the bloodstream quickly and spike insulin levels. Whole fruit, however, arrives packaged with fibre, water and polyphenols, slowing sugar absorption and supporting metabolism. “Same word, very different biology,” Dr Sethi notes.

Dr Sethi shares why fruit is not the problem

Whole fruit works differently in the body

Unlike added sugar, whole fruit contains fibre that slows digestion and prevents sharp glucose spikes. This is why an apple satisfies hunger, while a sugary snack often fuels cravings.

Not all fruit forms are equal

Dr Sethi points out that form matters more than fructose itself. Whole fruits such as apples, berries, citrus and pears support gut health. Fruit juice and dried fruit, however, behave more like sugar due to the loss of fibre and concentrated sweetness.

Sugar-free doesn’t mean nutrient-free

“Eliminating real food to avoid sugar is counterproductive,” says Dr Sethi. Whole fruit provides vitamins, antioxidants and hydration, benefits that added sugar simply doesn’t offer.

Who should be cautious

While fruit is generally safe, some people should monitor portions, including those with severe insulin resistance, uncontrolled diabetes or fatty liver disease with active inflammation. Even then, Dr Sethi emphasises that whole fruit remains preferable to added sugar.

Extreme rules rarely work

According to Dr Sethi, allowing fruit actually improves long-term compliance. “When diets become too rigid, people rebel,” he explains. Including fruit reduces cravings, lowers relapse risk and makes healthier eating sustainable.

“You don’t quit sugar by quitting real food,” Dr Sethi says plainly. In a true sugar-free challenge, whole fruit stays, added sugar goes.
