We should eat vegetables everyday.

In everyday usage, vegetables are certain parts of plants that are consumed by humans as food as part of a savory meal. Originally, the traditional term (still commonly used in biology) included the flowers, fruit, stems, leaves, roots, tubers, bark, seeds, and all other plant matter, although modern-day culinary usage of the term vegetable may exclude food derived from plants such as fruits, nuts, and cereal grains, but include seeds such as pulses; the term vegetable is somewhat arbitrary, and can be largely defined through culinary and cultural tradition.
