Like other dark green, leafy vegetables, spinach is a nutritional powerhouse. Because all methods of cooking destroy some nutritional value, the best way to maximize nutrient intake is to eat fresh spinach raw.
When that's not suitable, preserve most of the nutritional value by minimizing the water used to cook spinach and the cooking time. The best way to retain all of the antioxidants, vitamins and minerals when cooking fresh spinach is to steam it on the stove top.
