Scientific American’s John Rennie on the 21st century paradox of feast and famine.
Widespread hunger along with widespread overabundance mark these early years of the 21st century.
That’s according to a special Fall 2007 issue of the magazine Scientific American devoted to food and health. Here’s editor-and-chief, John Rennie:
John Rennie: The odd thing is that these days, there’s probably as much obesity and overweight in a lot of the developing world as there is in the industrialized world. At the same time, we still do have 800 million people in the world who are slowly starving because they are not getting enough to eat.
Rennie said that about one in five people on Earth is overweight. There’s an explosion of high-calorie foods, such as sugary beverages, which are now more easily available to people across the globe.
And the report also talks about the spread of unhealthy diets more common to rich parts of the world, now causing a spread of diabetes worldwide. For example, diabetes was almost nonexistant in Mexico 15 years ago, but now it affects one in seven people there
John Rennie: It was a disease of affluence. But these days, it’s one of the fastest rising health problems in the developing world.
