Diet-related illnesses are causing nearly as many deaths as tobacco-related illnesses, not to mention the impact on quality of life when you start to develop adult-onset diabetes as a child, or all these other diet-related illnesses.

Part of what the food industry does with public relations, just like the chemical industry or the oil industry, is to try to erase their fingerprints from their messaging.

Just in the past couple of years, there's been pushback against some of that marketing, as parents have gotten really upset. Now we're seeing Coke and Pepsi kind of shape-shifting. Instead of doing these very explicit marketing deals, they are getting into schools in much more hidden ways - things like My Coke Rewards, where they encourage schools to push their student body to purchase Coke products, in exchange for points that go toward various products for the school. It's a way for these companies to get in front of kids, presented as a form of charity.

Every time you spend money, you're casting a vote for the kind of world you want.

When people hear about legal restrictions on marketing and advertising, often the response is: Aren't you just being a food nanny? Isn't that government playing too much of a role in our lives? When people have that response, they're forgetting the extent to which what kids are eating and drinking is having as much of an impact on their lives as, say, if they were starting to smoke cigarettes as teenagers. Diet-related illnesses are causing nearly as many deaths as tobacco-related illnesses.

Part of what the food industry does with public relations, just like the chemical industry or the oil industry, is to try to erase their fingerprints from their messaging. So when consumers hear about a recent effort like the "food dialogues" put on by a group called the US Farmers and Ranchers Alliance, do they know necessarily that these "dialogues" are being funded by companies like Monsanto, a large chemical company and the controller of most of the patents on genetically modified seeds? No, they don't.

To argue that we need some technology in order to produce food to tackle hunger is completely blind to the facts on the ground. Actually, what we need is the exact opposite of what GMOs give us. We have to empower farmers to grow food for themselves and plant and grow their own seeds and use practices to deal with weeds and the need for fertility, not from purchased products like a seed or a chemical, but from their own farms, from their own knowledge and skill sets.
