A few weeks ago a friend and I saw the film Food Inc. I've always known that some of the food we eat isn't exactly healthy, but the film illustrated how almost all of the food we eat is all part of a huge system. A really messed up system.
We all know it's expensive to eat healthy; a bag of spinach is more expensive than a pack of Little Debbie's--my number one enemy of all snack foods. The answer lies across the entire midwest-corn and soy production. Because the government subsidizes these crops, they are super-cheap and have found their way into nearly everything we eat. We see "partially hydrogenated soybean oil" on peanut butter and salad dressing, but what is that? Partially hydrogenating the oil causes it to become saturated and harder. In a few years that yummy cream from the inside of your Swiss Roll is going to be some not so yummy buildup in your arteries. Here's what's going into your body...
Sugar, Corn Syrup, Water, Enriched Bleached Flour (Wheat Flour, Niacin, Reduced Iron, Thiamine Mononitrate [Vitamin B1], Riboflavin [Vitamin B2], Folic Acid), Partially Hydrogenated Soybean and Cottonseed Oil with TBHQ to Preserve Flavor (Contributes a Trivial Amount of Trans Fat), Palm and Palm Kernel Oil, Dextrose, cocoa, Eggs, Soybean Oil, Colors (Caramel Color, Red 40), Emulsifiers (Sorbitan Monostearate, Polysorbate 60, Mono- and Diglycerides, Soy Lecithin), Whey (Milk), Leavening (Baking Soda, Sodium Aluminum Phosphate), Salt, Corn Starch, Sorbic Acid (to Retain Freshness), Natural and Artificial Flavors, Egg Whites, Citric Acid.

Above is a map from the USDA that shows where and how much corn is grown. Most of the corn that's grown in America is used for animal feed (even though most of the animals that are eating it should naturally be eating grassy stuff). Because the government subsidizes the corn, it can be sold at super-low prices and exported (about 20% of the corn the US grows is exported). International growers are unable to compete with these prices, so those farmers are put out of business. The low prices also allow American manufacturers to find great places to put corn in--like our juices and even our plastics.
Similarly, soybeans are grown all over the Midwest (the largest protein feed, and second largest source of vegetable oil), and have become cheap substitutes in foods because they easily modified to play a hundred different parts in a hundred different foods. Soybeans and soybean products are second only to corn in production. The most common one that everyone knows is the partially hydrogenated soybean oil, which i mentioned a little about before. We HAVE to stop putting this junk in our bodies.

So...now we know why things that are good for us are more expensive. They are generally less subsidized, so they are grown a lot less. Take a look at how much Americans are growing sweet potatoes (you know how much i love sweet potatoes.):

and peas (not my favorite, but still)...
