Aoife Hearne: My teenage daughter has switched to low-fat milk 

"Consuming enough energy from varied food sources is essential. All the macronutrient groups (carbohydrates, protein, and fat) play an important role in health and sporting performance."

Both high- and low-fat milk are considered part of a healthy, varied eating plan.

My sporty teenage daughter has switched to low-fat milk, saying it keeps her fuller for longer. I would have thought it’s better to stick to the full-fat version as it’s closer to the original. What would you advise?

Teenage athletes engaged in sports have unique nutritional needs. At this age, the food and fluids your daughter consumes are required for growth, maturation, and the energy demands of her sports.
