One of my clients is currently recovering from a major surgery, and that means the body needs to do some serious rebuilding. Collagen is the major building block for connective tissue, and so we want to make sure collagen synthesis is maximized.
There are a few nutrients that you should be particularly concerned with in this case. This is not at the exclusion of other nutrients or a generally healthy dietary pattern. This is icing on the cake - potential marginal improvements. Don't limit calories significantly while trying to recover. Rebuilding tissue is energy demanding - calories are that energy.
Protein - provides necessary amino acids for collagen synthesis
Copper - cofactor for Lysyl Oxidase
Iron - cofactor for procollagen peptidases
Vitamin C - cofactor for collagen hydroxlases
Vitamin A and Manganese - required for glycosylation of hydroxylysine
Zinc and Calcium - cofactors for proteinases
I will be adding this information to my nutrition e-book which I am hoping to finish this month. You guys will be the first to know about that, and will get it for free.
