The chief mineral salts in green vegetables are iron and calcium. These minerals are essential for our body to function properly, and they are particularly important for maintaining strong bones and healthy blood cells. Iron is necessary for the formation of hemoglobin, a protein in red blood cells that carries oxygen throughout the body. Calcium is needed for the growth and maintenance of bones and teeth, as well as for proper nerve and muscle function. Green vegetables are a good source of these minerals, as well as other important vitamins and nutrients, making them an important part of a healthy diet. Therefore, including green vegetables in your diet can help you meet your daily recommended intake of iron and calcium, and support overall health and wellness.
