The demand for food will increase by 80% by 2100 due to heavier and taller human
Scientists have warned that suppliers won't be able to keep up with food demands that are predicted by 2100. This increase is due to the human race becoming heavier and taller with a rising BMI.
BMI: the calculation with weight and height of a person which equates to Body Mass Index, is set to rise throughout the world resulting in global calorie requirements. A study from University of Göttingen has indicated that this rise in requirements could increase by 80% between 2010-2100 with 60% of this due to population growth.
Doctural student Lutz Depenbusch has stated; “The developments in these countries are very pronounced,” said Dr Depenbusch, “but they do represent a realistic scenario.”
“This would lead to increased consumption of cheap food, often rich in calories but poor in nutrients,” said Dr Depenbusch.
The effects of this would effective the poor of the world to a greater length due to the increase in prices, while the rich would mostly likely be able to maintain their lifestyles.
What effects have been seen so far?
Over the last century men and women have both experienced an 11cm increase in height, with men now averaging at 5'10 and women 5'3.
Surprisingly, despite Mexico having suffered from malnutrition until the 1980's, they are now second to the USA in the BMI rankings; seven out of ten being obese.
