Abstract
Aim: Current knowledge of protein intakes of Maori in advanced age is extremely
limited.
Methods: Dietary intakes of 216 Maori men and women aged 80-90 years were
assessed using two 24 hour multiple pass recall dietary recalls. Energy, protein and
nutrient intakes were analysed using FOODfiles 2010. Animal vs. plant protein
intake, protein intake distribution and protein intake from Kai Maori and
contemporary Maori foods protein intakes were examined.
Results: Protein intake and percentage of energy as protein consumed met the
nutrient reference values for both genders. The intake of animal protein (men =
52.?g, women= 36.6g) was higher than for plant protein (men= 19.Sg, women=
18.5g), and the animal: plant ratios for men and women were 2.63 and 1.94,
respectively (p=0.009). Poultry, fish and seafood were the highest contributors of
protein intake and percentage energy of protein in men and women. Protein intake at
breakfast (men= 11.?g, women= 9.?g) and lunch (men= 16.Sg, women= 14.Sg)
were inadequate (<30g protein per meal) and similar between the genders (p>0.05).
Men consumed a larger median amount of protein at dinner than women (34.4g
versus 23.3g, p<0.001). For men and women respectively there was a low
contribution of protein from Kai Maori (median 1.31g and 1.08g) and contemporary
Maori foods (median 3.28g and 2.65).
Conclusion: Advanced age Maori met the total and percentage of energy protein
requirements but protein distribution was inadequate in light of recent evidence.
They had a higher intake of animal compared to plant protein foods. Traditional
Maori foods contributed only a small proportion of protein to the diets of these
advanced age Maori.
