Capitalism is a good thing - or so we believe. The world is getting more obese. Large international companies that produce high-sugar, high-fat products are buying out local distribution firms in developing countries to dominate the market.
More than a Quarter of China's population is obese. Twenty years ago each Chinese person consumed only two teaspoons of sugar a day. Currently, China keeps a sugar bank, The government is terrified that a sugar shortage will lead to social unrest.
Mexico is becoming fatter than any other nation on Earth. Coca Cola practises price segmentation. In cities where income is higher, coke costs more than average. Poor rural regions get coca cola at a much cheaper price. Young children suffer from malnutrition while their parents are overweight.
Sugar and fat consumed regularly is a killer. Diabetes is increasing at a rapid rate. In developing countries medical care is poor, so diabetes goes untreated and people die. There can only be one result from this: countries will legislate to stop the sale of the "wrong" food. Having a coke as a treat is okay, but having coke every time one eats leads to disaster. Getting the younger generation to go back to eating nourishing vegetables is going to be a major problem. You can change a person's behavior temporarily. To change what people feel they have a right to is impossible.
