Body Composition, lifting and nutrition for the over 60's

Is it a waste to take too much protein powder at once because some of it won't get absorbed?

Animal Vs Plant (the norm subject)

Does the literature still show that an additional 30-40% of plant derived protein is required to equate a similar response from animal protein? Isolates and sources such as mucoprotein play a role? How does this increase play out when looking at the viability of plant protein in older populations that exhibit anabolic resistance? Is animal protein really still the gold standard? And required as a "high quality" source, especially when dealing with sarcopenic/ co-morbid individuals, who eat less/ move less etc?
