How many grams of protein should a female, 43- be eating daily?

The usual: recommendation of 0.5 - 0.7 grams of protein per pound of body weight. This is the minimum for a healthy adult male or female. So for a normal weight, 145 pound woman, this would be about 70 to 101 grams per day. Many would say to bump this up to 0.8 - 1.0 gms/lb , or 116 gm to 145 gms, for this same woman, when one is trying to build muscle, and perhaps, to lose weight. Hope this helps!
