The high amount of vitamin A in spinach also promotes healthy skin by allowing for proper moisture retention in the epidermis, thus fighting psoriasis, keratinization, acne and even wrinkles.
One cup of boiled spinach provides over 1000% of the RDA of vitamin K that can prevent excess activation of osteoclasts (the cells that break down bones), as well as promote the synthesis of osteocalcin, the protein that is essential for maintaining the strength and density of our bones.
Vitamin K is a crucial component of the process called carboxylation, which produces the matrix Gla protein that directly prevents calcium from forming in tissue. Eating one cup of spinach contributes to this process that fights atherosclerosis, cardiovascular disease and stroke.
Brain and Nervous Function
The abundance of vitamin K in spinach contributes greatly to a healthy nervous system and brain function by providing an essential part for the synthesis of sphingolipids, the crucial fat that makes up the Myelin sheath around our nerves.
