A maximum of 7 gm. of protein is recommended in the literature from the various PD support groups, but the RDA (Required Daily Allowance) for proteins is about 0.36 gm./lb. of body weight or from 30 to 60 gm. How then is the recommended 7 gm reconciled with the RDA? what does one substitute for protein that is ubiquitous in most food staples? Michel Margosis
