If eggplant replaces a daily intake of spinach, which key nutrients would likely be lost due to this substitution?

Substantial iron and Vitamin A

When evaluating the merits of daily consumption, it is important to benchmark eggplant against other vegetables to ensure nutritional diversity is maintained. If eggplant, which is relatively low in Vitamin A, replaces spinach in a daily vegetable slot, the individual would miss out on the substantial concentrations of iron and Vitamin A that spinach provides abundantly. Spinach is known for being an excellent source of both these elements. Conversely, while eggplant offers high levels of unique antioxidants like nasunin, substituting it for spinach means foregoing the rich iron and Vitamin A content typical of dark leafy greens, illustrating the need for a varied vegetable intake.
