Spinacia oleracea
Spinach
Owing much of its fame to Popeye's excessive eating of it, spinach has far more benefits than helping you get strong. Native to Asia but popular worldwide, spinach is very popular cooked or even used in some salads or sandwiches.
The three most common varieties of spinach are savoy spinach, flat-spinach, and semi-savoy spinach.
Spinach is another dark leafy green vegetable but its taste separates it from the rest of the pack.
