I am thinking of how many times I have dreamed of living in the country, raising my own crops and living off the land and our own animals for subsistence. I hear you, and understand.
I am disenchanted with all the processed foods that even though we know are not good for us and can cause health problems, we still consume. Let's face it, it is easier to let your kids have a couple pieces of candy than say no, sorry, you can't eat any of this delicious stuff you just collected over the last 3 hours. :)
What I have done is started with baby steps. We try to eat organic and locally grown produce as much as possible (and knowing what is important to get organic is the key)to avoid the pesticides, drinking organic milk, etc. is one thing we have done. Of course, there is a cost involved in this, but we find it worthwhile to know we are eating safer. I use all natural turbanado sugar that I order from Amazon.com because it is cheaper in bulk with free shipping. I use unbleached flour.
I don't deny my daughter commercialized candy within reason. I think that will make it too tempting to hoard and over consume when she gets older. I had friends as a child who were not able to eat sweets in their own home, and when they'd come over to our house it was like they'd o.d. on them. To me it was no big deal so I didn't overdo it.
I'd probably change my tune if my daughter had a rash like yours did, though! Fact is, you never know what reaction can come from foods. Some people are one day not allergic to peanuts, and the next time they have some, their throats close up!
I've also changed our home environment to one that is not full of caustic products, which has made a huge difference in our health. This I have been able to do while saving money, so it makes up for the changes in foods that we buy.
Anyway, don't go to the Amish lifestyle...LOL...just take some baby steps to change what you can change!
