The demand for food and the overconsumption of food is creating huge problems for the sustainability for food security. This great interactive map shows the percentage of people’s total expenditures spent on food in that country. http://civileats.com/2011/03/29/mapping-global-food-spending-infographic/
I think it pretty succinctly shows a massive problem coming from the USA with the average person spending 7% of their income of food. These low food prices combined with the general lack of knowledge about food, create a huge problem. Post-industrial food systems also add unnecessary calories at all stages (production, processing, distribution, acquisition, preparation, and consumption). This leads to people eating extra calories and in combination with their sedantary lifestyles can negatively impact the health of the individuals. Obesity amongst Americans is estimated at being 2/3 of the population, but on the other hand there is also a huge problem with hunger amongst the poor in the USA. 1
Another problem with the increase in food production to meet this demand is that more food means that more water is used to grow these foods as well as the increased use of pesticides and fertilisers. As someone who is anti-Monsanto, and is a proponent of organic and permaculture gardening techniques. I find it very disheartening to know that the western demand for easily available food in our supermarkets is leading to this incredibly important issue within food security.
Now as a plus size woman I know that I my diet needs to be drastically changed in order to be healthy and for me not to be guilty of this culture of overconsumption. But by using our allotment garden and my husband and I both eating a plant based diet, we are attempting to resolve our dieting problems.
