Sulfur is present in every cell of the body, and is especially concentrated in the skin, nails, and hair. Most sulfur in the body is obtained as part of the protein intake, as it is an integral part of the sulfur containing amino acids cysteine and methionine. It is also a part of at least three B vitamins; thiamin, pantothenic acid, and biotin. Inorganic forms of the mineral – sulfide, sulfates, and sulfites – are not needed in the diet. Indeed, chemical sulfites, used to preserve the color of dried foods (such as apricots), may trigger asthma attaches in susceptible individuals. In its pure form sulfur acts as an antifungal and antibacterial agent, and is used in creams for treating skin disorders such as acne. Sulfur helps to reduce pain and arthritis conditions. A deficiency of sulfur increases the chance of infections and fungal disorders and promotes bone erosion.
Sulfur is found in cabbage, kale, Brussels sprouts, onions, garlic, and their sprouts.
