The chart below from the Bureau of Labor Statisitics has some intriguing data on what we spend our money on in the grocery store.
A quick glance at this chart may seem like meat consumption has decreased since 1982. This is not true. Instead, the price of meat has decreased, and we are eating about the same amount of it as 30 years ago. So, why did the price drop? Large, factory farms have taken over the market, they feed their animals cheap corn, grow their animals larger than what is natural, and have increased that rate of which they can slaughter.
The best way to combat processed food spending is to buy as much as you can from farmers markets and local producers, or grow your own food in a backyard garden. Choosing meats from a farm you know feeds their animals grass is another step in the right direction. If buying processed food, it is always a good idea to read the ingredients and make a choice from there.
