Iron
Spinach is also rich in iron, which supports energy production and promotes gastrointestinal health. It is advisable to complement foods rich in calcium with those rich in vitamin-C for increased absorption of this nutrient. Iron deficiency may alter how your immune [10] system responds to invaders. Iron helps the growth of white blood cells called lymphocytes, which protect the body from diseases and infections.
Phosphorus
Phosphorus helps increase energy production for high-intensity activities like exercise and speeds up the recovery of muscle tears and soreness post-workout. Phosphorus is necessary for the growth, maintenance and repairment of body tissues and cells. Its deficiency may cause anemia [11] and bone deformities.
