A high risk of type 2 diabetes?

Levels of protein in early field rations were probably excessive, largely due to the reliance on pemmican as a primary constituent of the ration boxes and resulted in protein contents of up to 33% in some expedition field rations (Orr 1965). Carbohydrates are the other important macronutrient component of field rations and it was found during trials on the Australian National Antarctic Research Expedition (A.N.A.R.E) that men developed cravings for sweet things and not fatty things (Law 1957). Sugar was used extensively to satisfy this craving for sweetness and provided a readily absorbed source of energy from carbohydrate (Law 1957).
