DAIRY: First of all, I try to use minimal dairy. I think we have an overabundance of it in our American diets. But we still go through about a gallon of milk a week and about a bag of shredded cheese. On the weeks I shop at Trader Joe's or MyOrganicMarket(MOMs) for $5.50 a gallon, I purchase organic milk. When I'm at Costco on the alternate weeks, I buy their milk, which is just over $3. I figure organic half the time is a step in the right direction, and it winds up costing as much as buying milk at a regular store every week. But as money becomes available, I do intend to buy more organic dairy products. And even when money is tight, I only buy dairy products which state that the cows are not treated with rBGH. It is inhumane to use on the animals, and may have negative effects on humans who consume them. Cows treated with this hormone require lots of antibiotics(for mastitis) which many believe can lead to antibiotic resistance in humans.

MEAT: After realizing how badly animals are cared for, and how contaminated our meat is, I have become more determined to eat only organic meat. My ideal would be to buy from small local farms! But that is just not in the budget yet. So for now, I am cooking mostly vegetarian dishes, so that I can afford to buy organic chicken breasts. Again, cooking less expensive meals has allowed for the "splurge" of happier chickens. The taste is SO much better too! We almost never eat red meat or pork, and when we do, I buy "natural" but not organic. The only fish we eat right now is canned tuna, and that is not organic, but I'm not convinced that is as much of a problem.
PRODUCE: This year, I made huge efforts to buy only seasonal produce. That means for a large portion of the winter, we did not have fresh fruit. (I make an exception for bananas, cause really, when are they "in season"? and we can never by local for those either!) It was tough, but we saved money, didn't settle for eating something that tasted only slightly better than wax fruit would, and took better care of the planet. Raisins and applesauce saved the day! And I have to say, I've never been more excited about summer fruits and veggies! But back to the point, I always try to buy local (from farmers markets mostly), but not always organic. Even in the summer, organic produce is still pricey, so I need to be wise about what I purchase. Someone has come up with a list called the "dirty dozen", which recommends avoiding produce that is most potentially hazardous. So this summer, I intend to make an effort to buy this "dirty dozen" either organically, or from farmers who use minimal pesticides. I'm not going to buy any other organic produce, at least for now.
