Professor clarifies old saying on feeding a cold and starving a fever

A professor from the University of Southampton, Tom Wilkinson, supports the saying "feed a cold, starve a fever." He explains that a strong immune system requires energy, which comes from nutrient-rich foods, especially during a cold. Wilkinson notes that studies show those who eat during a cold have better immune responses. He advises against dieting when sick, particularly for those with weakened immune systems or malnutrition. Regarding fevers, Wilkinson suggests the phrase may have been misinterpreted. He emphasizes the importance of a balanced diet and hydration for effective immune function.
