Which of the following contribute to a healthy diet?

Vitamin E is important for maintaining healthy skin and eyes, and it has antioxidant properties that protect cells from damage. However, while it is beneficial, it is not as universally recognized as essential for a healthy diet as Vitamin C, which plays a more direct role in various bodily functions.

Vitamin B12 is crucial for nerve function and the production of DNA and red blood cells. Though it is an important nutrient, particularly for those on a vegetarian or vegan diet, it does not contribute to overall dietary health in the same broad and impactful way that Vitamin C does.

Vitamin A is vital for vision, immune function, and skin health. While it is significant for specific bodily functions, it does not encompass the wide-ranging health benefits attributed to Vitamin C, particularly in terms of tissue repair and immune support.
