The beetroot is the taproot portion of the beet plant, also known in North America as the table beet, garden beet, red or golden beet, or informally simply as the beet. Its distinctive deep purple color is visible on the roots and on the inside of the beet itself (Wikipedia, nd).
Other than as a food, the beet’s uses include food coloring and as a medicinal plant. The usually deep purple roots of beetroot are eaten either grilled, boiled, or roasted as a cooked vegetable, cold as a salad after cooking and adding oil and vinegar, or raw and shredded, either alone or combined with any salad vegetable (Wikipedia, nd).
