The rising food demand is not just a result of the global population growth [although the planet can expect (UN medium variant) an estimated 2.3 billion extra people in 2050 — as no one even mentions the possibility of policy on that front]-- but also of an increasingly decadent
average food consumption pattern, in which (next to globalisation of food production) the rising consumption of animal protein plays a key role.
Also steadily increasing is the
average dietary glycemic index (GI) 9 in the United States (5), with the global
consumption of refined
foods also increasing as more regions of the world adopt westernized dietary
patterns.
