Cuts and bruises that heal slowly are commonly linked to low zinc, low vitamin C, or inadequate protein, all essential for tissue repair.

Zinc and vitamin C are required to build new tissue and collagen, so a shortfall slows healing and is more common in older adults and those eating little fresh food. Adequate protein supplies the raw material, and poorly controlled blood sugar also delays healing.
