METALS AND MINERALS
Potassium is the major mineral in most root crops while sodium tends to be low.

They also supply some of the key metals and minerals for good health: magnesium, iron, zinc, manganese, calcium and phosphorus requirement of adults.
Here’s what the they do for us, according the Harvard Medical School (Harvard Health Publishing):
Calcium builds bones and teeth; activates enzymes throughout the body; helps regulate blood pressure; and helps muscles to contract, nerves to send messages, and blood to clot.

Chromium helps maintain normal blood sugar levels and helps cells draw energy from blood sugar.
Copper assists with metabolizing fuel, making red blood cells, regulating neurotransmitters, and mopping up free radicals.
Iron helps make hemoglobin (the oxygen-carrying chemical in the body's red blood cells) and myoglobin (a protein in muscle cells). Iron is essential for activating certain enzymes and for making amino acids, collagen, neurotransmitters, and hormones.
Magnesium, like calcium, builds bones and teeth. It also helps to regulate blood pressure and blood sugar and enables muscles to contract, nerves to send messages, blood to clot, and enzymes to work.
Manganese helps form bones and helps metabolize amino acids, cholesterol, and carbohydrates.
Potassium balances fluids in the body, helps to maintain a steady heartbeat and to make muscles contract, and may benefit bones and blood pressure.
Sodium balances fluids in the body, helps send nerve impulses, and helps make muscles contract.
Zinc helps blood clot, helps make proteins and DNA, bolsters the immune system, and helps with wound healing and cell division.
