Since My blood sugar went nutso a few months back we have tried to buy/eat better. We are buying a few organic items (not all that many around here, at least until the farmers markets get up and running) and it ain't easy. When you've eaten for convenience all your life, changing is REAL hard.
We all face the food challenge. Your local Walmart is likely carrying organic foods now. Be sure to ask detailed questions of your suppliers at farm markets. Ask about fertilizer use, etc.
We've all subcomb to the convenience food trap. It's easy to stop at a drive thru on the way home or to order a pizza. This is alright OCCASIONALLY if you chose well (Jason's Delis, Moe's, etc are chains that have healthier options and even "good" options if you discount the hidden calories and processed food component). The idea is to win the war knowing you'll lose a few battles.
We try to have some healthy "easy comfort foods" available at home. This includes a couple of organic frozen pizzas (we use to order them thru Azure Standard but they're now available in most frozen food sections), a box of organic poptarts, etc. These products aren't the normal fare - they are special treats for occasional use.
Many people think they don't have time to eat properly. If anyone is reading this, and feels that way you need to re-evaluate your life. Your priorities are very skewed. Up until the mid 20th century most of a person's time was spent in the pursuit of and preparation of food. Food is the single most important item on your daily agenda. Plan your life around your meals and you'll find a whole new appreciation for life.
