Root Vegetables for Health

Root vegetables are grown underground away from pests and pesticides and are very good source of nutrition and fibers. Although technically root vegetables are confined to tuberous roots like beets, cassava (tapioca), carrots, horseradish, radish, rutabagas, salsify, turnips and parsnips, it is not wrong to extend them to bulbs like onions and garlics, rhizomes like ginger, tumeric and galangal, tubers like potatos and all edibles cultivated underground. Since they retains little pesticides, I would classify them as better alternatives to the above ground fruits and vegetables like stawberries, tomatoes etc which have very high pesticides residues.
