Mayo dieticians typically recommend 1.2 gr of protein per 1 kg of body weight for older women. I did the math - that is 50-55 grams per 100 pound of body weight. The dietician at our local hospital told me to eat 20% more after surgery to help in rebuilding.

I really think the biggest lesson I ever learned was "all things in moderation" - a yogurt smoothie with fruits and vegetables added sounds like it meets your dietary needs quite nicely. We use the bottles from supplemental protein drinks to portion out our smoothies and freeze them for snacks and light meals (paired with a small handful of nuts) when we travel.
