Which nutrient class is known to protect against cell damage?

The nutrient class that is known to protect against cell damage is vitamins. Many vitamins, particularly those with antioxidant properties, such as vitamins C and E, play a crucial role in neutralizing free radicals—unstable molecules that can cause oxidative stress and cell damage. By mitigating this oxidative damage, vitamins contribute significantly to maintaining cellular integrity and overall health.

Unlike vitamins, minerals also have protective roles in the body but are not classified primarily as antioxidants. Carbohydrates provide energy rather than directly offering protection against oxidative stress, while fats are essential for various bodily functions but can contribute to oxidative damage if not balanced properly within the diet. Hence, vitamins are the primary class of nutrients recognized for their protective effects against cell damage through their antioxidant capabilities.
