High Food Prices and the Global Epidemic of Obesity

Today, we know that being overweight or obese are major risk factors for diabetes, cardiovascular diseases, hypertension, and premature death. We are constantly reminded that personal behaviors, influenced by culture and lifestyle, and our metabolic development contribute to being overweight or obese. In the March 2013 Food Price Watch, we wonder how another factor could potentially influence the world’s obesity epidemic: high food prices.

But first, let’s run a quick quiz. Many of us watch our weight routinely and may even have figured out our Body Mass Index—the ratio of body weight in kilograms by the square of body height in meters—to determine whether or not we are overweight. Yet there are some stunning facts about being overweight that you may not know.

Can you answer the questions about being overweight or obese below?  

Questions about being overweight or obese

If you are surprised by some or all of these numbers, here is the most astonishing fact of all: Conservative projections predict that 2.16 billion adults will be overweight and 1.12 billion adults will be obese by 2030!1

An obvious question is how high and volatile food prices affect being overweight. The number of overweight and obese people has doubled since 1980 and accelerated since 2000, which means that the epidemic has spread during periods of both low and high food prices. But as food prices remain high and, arguably, increasingly volatile, unhealthy calories tend to be cheaper than healthy ones. This is the case of junk food in the developed world, but also of less nutritious food substitutes in poor households in developing countries coping with recurrent food (and other) crises.2 So, increasing prices of internationally traded and domestic food and/or increasing volatility augur the continuation of the overweight epidemic in the future.

Domestic policies have only partially addressed the problem. These policies range from doing nothing to punishing overweight people and promoting or compelling healthier behavior through taxes, bans, restrictive legislation on certain foods and ingredients, clearer standards for food labels, and awareness campaigns.

But preventing the global expansion of the overweight epidemic in a more prosperous world with high food prices requires integrated domestic and global collective action. Current multilateral discussions on the post-2015 Millennium Development Goals offer an unprecedented opportunity for combining global and national collective action to fight all forms of malnutrition, from stunting to obesity. Is it yet another global priority to add to the MDG to-do list?

The governments need to focus on meeting the basic necessities: clean water, shelter and clothing. In my opinion, half of issues faced by the developing world stems from inaccesabilty to these to not only people who are below the poverty line, but people bove it also. As long as governments cannot ensure these or teach people to attain self sufficiency though the optimum usage of natural resources, there can be no salvation. Along with infrastructure/agriculture, bank should also focus in this very primary need for remaining changes to follow.

I feel that obesity is a deep issue on the rise. As our economy tends to decline financially , we tend to make that money up by raising prices on our necessities. Obesity leads to many diseases, which is something people don't realize or they do for that matter , but simply cant afford to "realize." We all need to eat and most of us have large families , therefore, focusing more on quantity than quality. I'm sure most don't intentionally choose to eat unhealthy, its just that is what most are able to afford. I feel if prices did get down , especially on the nutritious foods , our obesity problem would start to decrease, which can still benefit America financially. There wouldn't be much of an issue in regards to medical cost, because some of the contributing factors would start to fade away.

I think obesity is still a problem in rich countries. Although not ruled out developing countries have the potential problem of obesity. Government in each country are responsible for the increasing number of junk food. Government shall campaign for healthy food through lifestyle and policy. I think the issue is not the time to add to the MDGs.
