Oncologist warns restaurant French fries may pose hidden health risks

Restaurant French fries may be a favourite fast-food side, but surgical oncologist Dr Vartika Vishwani urged parents to think twice before serving them to children. In an Instagram video shared on July 10, the doctor explained why she avoids commercially prepared fries for her own child, citing concerns about reused cooking oil, excess salt and their contribution to obesity.

Doctor explains concerns over restaurant French fries

Dr Vishwani said her biggest concern is not the potato itself but the way French fries are prepared in many commercial kitchens. According to her, restaurants often reuse the same frying oil multiple times, which can alter its chemical composition.

She said repeated heating increases trans fats and other harmful compounds in the oil. These substances may contribute to oxidative stress and inflammation in the body when consumed regularly.

Reused oil and excess salt raise health concerns

The oncologist also pointed to the high salt content of restaurant French fries, saying frequent consumption could increase the risk of developing high blood pressure over time.

She added that French fries are energy-dense but low in nutrients, making them easy to overeat without providing lasting fullness. According to Dr Vishwani, this can contribute to weight gain, particularly among children.

Doctor urges parents to limit restaurant fries

While Dr Vishwani advised against regularly buying restaurant French fries, she distinguished them from homemade versions prepared occasionally with fresh oil.

She encouraged parents to reconsider making French fries a default choice when eating out and to be mindful of how often children consume fast-food snacks.
