I chose "other" because I feel it is becoming a very nebulous statement to say that one is "eating healthy".
For the most part, my wife and I have joined the Farmer's Market crowd and we get almost 100% of our vegetables and fresh herbs from there, or the CSA share we're splitting with another couple over the winter.
There are at least 3 reasons we're doing this:
1) Small farmers tend to treat their crops better, so we get better product (more nutrients, tastes better, etc)
2) Small farmers are actually pretty inexpensive, especially when you think of the sustainability of the land they are tending compared to mega farms
3) We really like the idea of buying local
The fact that we're getting better food, and thereby eating healthier is a secondary outcome of our choices.
We also try to cook as many of our meals as we can. It's cheaper in the long run because the cost of any additional processing done on the food is offset onto the consumer. e.g. frozen boneless, skinless chicken breasts cost more than a whole frozen chicken, etc.
The less processing done on our food by someone else, the less chance there is to get unwanted products in our food, like the many varieties of processed corn: HFCS, corn starch, dextrose, maltose, maltodextrin, sucrose, mono- and di-glycerides, sorbitol, etc.
This does mean that we have to do a lot of the processing ourselves which is time consuming, but I cannot tell you how satisfying it is to have a can of the spaghetti sauce we made during the summer from fresh tomatoes, zucchini, garlic, onions, green peppers, spinach, celery, rosemary, oregano, thyme, and parsley. I pulled it out of the pantry and looked at it to confirm the ingredients. If the one quart jar is not enough, we can add another can of diced tomatoes, and thicken it with a can of tomato paste when we heat it back up.
I've benefited a lot from my wife's ambition to get into preserving food by dehydrating, canning, and freezing; it's been a lot of fun finding and using recipes, too. We've learned how to make pickles, jams and jellies, and dessert sauces in addition to preserving vegetables and fruits just by themselves.
And so, I feel this is a much different path than deciding to shop at a "natural" grocery rather than a large chain, or buying "healthy" food instead of "junk" food.
