Are fries healthier than boiled or baked potatoes?

According to a report from Vietnam.vn, fried potatoes would be healthier than boiled or baked potatoes. The source's argument is that frying potatoes preserves certain nutrients better than other cooking methods. It is unclear whether this is based on scientific evidence.
Nutritionists in the West generally advise boiling, steaming, or baking potatoes instead of frying them. This is due to the high fat content and the possible formation of harmful substances during frying. The claim of the Vietnamese source is in stark contrast to these guidelines.
It is unlikely that there will be a consensus soon on the health effects of different ways of preparing potatoes. For now, the advice remains to vary in the kitchen and to enjoy fried dishes in moderation.
