Killer at Large... so what do we eat??

     Last night my husband and I watched a pretty fantastic documentary called Killer at Large about obesity in America. It looked at some of the reasons why so many of us are finding ourselves at war with food and our bodies. Having had an eating disorder I empathized with people's sense of loss, confusion and desperation when it comes to finding a meal and exercise plan that works for real people and it healthy. We're so overwhelmed with choices, flooded with food advertising, battling our biology which is programed to hoard calorie dense foods, coping with stress and the cost of eating nutritionally dense 'health' or whole foods. I would love to shop in the all organic section at Whole Foods, but my budget simply can't support that.
   That being said I have found a way to eat mostly whole foods and some organic foods on a food budget of about $350 a month (for two people), but in evaluating it I'm wondering if it's varied enough. I mean, is it unhealthy to eat 12 to 18 egg whites a day considering that it gives me the protein I need to work out, feel strong and build good muscles and it's not actually killing an animal or messing with my hormones (as in the case with too much soy)? I used to eat lots of soy, but those frozen veggie burgers just seemed to have too many ingredients and too much soy. In the past year I've given up whole milk dairy, white sugar and almost all cereal (mostly because I can't stop eating it once I pour a sad little one cup serving, probably because of the sugar) and I've found a bread replacement that's affordable and has about 4 ingredients and no high fructose corn syrup (something that seems to trigger my brain to eat and keep eating, not mention the whole corn/oil, King Corn controversy). I've replaced all those fillers with more fruit and more greens but I end up buying the same fruits and vegetables every week because I know how to cook them and they fit my budget. I like my current diet because my skin is clear and my body seems to be pretty happy. But, am I supposed to be doing more? And, if so, how much more and just...how?
   My question is, what's your meal plan look like? How do you approach food? How much time to do you have to prepare food? How important is it to rotate your fruits and vegetables?
I'd love to know what the spokespeople for healthy eating are eating. I'd love to have a guideline about meal planning that doesn't come from someone who's trying to sell something; be it a giant food company or a farmer or our government or someone who wrote a book. I still wish that I could afford my own, private vegan chef to take some of the time, money and confusion out of meal planning, at least during the work week. Until then, I'd love to know what you ladies think. Let's simplify it together!
