World Food Security under threat due to overweight and obese population

The world food security is in danger due to overweight population. Scientists are ringing alarm bells that if obesity continues to be unabated then the global population is in danger of running out of food. The additional pounds carried on by the fat people may have the same significance that is equivalent to food energy needs/demands of one billion people.

The researchers carried on this study after examining the average weight of the adults across the globe. The authors of the study team were the scientists from the London School of Hygiene and Tropical Medicine that further suggests that confronting the population weight is the need of the hour for food security. As per their study, not only the population growth, a major threat for the worlds’ food security and environmental sustainability but population fatness or obesity is also an important factor in toppling the apple cart of food security. Professor Ian Roberts at the London School of Hygiene and Tropical Medicine or LSHTM has led this research team.

As per the United Nations predictions by the year-2050, the global population will be 2.3 billion people, this increase in population will have additional consequences to worry about, and that includes obesity. As per the study published by the BioMed Central or BMC Journal on public health, the world’s adult population weighs around 287 million out of which 15 million are overweight and another 3.5 million are obese.

Data collected by UN and World Health Organisation shows that during the year-2005, the average global weight per person is 62 kg and Britons weighed 75 kg and in the United States, the average adult weighed about 81 kg. In Europe, the average weight was 70.8kg and in Asia, it was 57.7kg. The data further revealed that more than half of the people living in Europe are overweight when compared with just less than 1/4th of their Asian counterparts. Further about three-quarters of people living in North America were overweight and it is quite ironical that only six percent of the world’s population lives in this continent but 34 percent of the world’s biomass due to obesity exists in these populations.

The other side of the coin is that Asia has 61 percent of the world’s population but only 13 percent of the world’s biomass due to obesity exists. Researchers further opine that if all the global population has the same body mass index or BMI, as Americans then the total biomass would further increase by 58 million tons. United States of America is one of the leading countries with the most obese people and this is one of the major causes of concern to the world’s food security.
