If you want to change the world, change how you eat. If you have any doubt about that, just consider the source of your food.
Supermarkets are not in the business of providing wholesome food from farms. Their business is making profits off whatever can be passed off as food. The pastorial farm so often alluded to in advertisements and on packages has no basis in reality.
If they wanted to give you a real impression of what they sell, most food images would look more like the conglomeration image above. The graphic is composed of actual food industry factories. Kinda hard to see any difference between them and automobile or petroleum or chemical plants, is there? The business of food is, first and foremost, about the business of making profits.
More definitively showing the reality of what’s become of our food production, take a look at the infographic below called ConglomerATE by the Frugal Dad. Did you know that the average man in the US will eat 35 pounds of antibiotics during his lifetime, if he eats supermarket meats and prepared foods?
The moral is simple: If you want to change the world, change how you eat.
