Uwe Knop, a certified nutrition expert, challenges the common categorization of food into 'healthy' and 'unhealthy', a distinction he believes is scientifically unsupported. Knop asserts that the evidence available is too limited to assess foods in black and white terms. Instead, he promotes the idea that eating is a biological process that varies from person to person, suggesting that fries deserve a better reputation than they often receive.

In his reflections, Knop emphasizes that fries primarily consist of two ingredients, potatoes and vegetable oil, with frozen fries typically containing about 96% potatoes and 4% vegetable oil. This composition implies that fries are not as detrimental as commonly portrayed and can be enjoyed as part of a balanced diet when understood in the context of individual dietary needs.

The article frames Knop's opinions as derived from personal experience and expertise, emphasizing the importance of a nuanced perspective on nutrition instead of rigid dietary classifications. His insights suggest a shift in how society perceives certain foods, advocating for a more individualistic approach to eating that recognizes variations in dietary requirements and preferences among people.
