A June 2019 study by the University of Eastern Finland and Kuopio University Hospital found that, “Adequate intake of protein [defined as at least 1.1 g per kg of body weight] is associated with a reduced risk of frailty and prefrailty in older women.” And, “…the consumption of animal protein was associated with a lower likelihood of frailty.”

“For someone weighting 70kg [this translates as] a minimum intake of 77 g of protein [and by way of illustration] the protein content of a chicken breast per portion is 25 g, one boiled egg is 6g, and two slices of whole grain bread is 6g.”
