Last week I was diagnosed with some stupid rare syndrome in which my stomach doesn't properly digest simple sugars. So I started a blog about my change in diet.
Sorry to hear that - it must be challenging to suddenly need to make changes in your diet, but at the same point it is good to finally know why you had issues with certain foods in the past.
If you can produce enough food for a family of 4 on an acre, 10 should be fine. Hell, I bet if you found a farm up this way, khoos would come help you tend to it.
