Vegetables are great. They give us health through the consumption of minerals, fibre and vitamins. Vegetable actually means the edible part of a plant excluding fruits and seeds, however most people just think of a vegetable as something to buy from the supermarket.
A vegetable can be a root variety like carrots and turnips or a leaf variety like cabbage and spinach or perhaps a bulb like onions. There are other types but really just describe the different parts of plant that are consumed. Vegetables are the most eaten food on the planet and make up the most important part of a healthy diet. Any plant that is eaten really could be thought of as a vegetable so therefore vegetables have been eaten by all herbivores and omnivores through history.
Most health organisations recommend eating 5 portions of fruit or vegetables every day as part of a healthy diet.
