If you've decided to try whole foods cooking, you may at first be overwhelmed by the number of "recommended" gadgets - especially if you read Nourishing Traditions like I did! It's a great book, and I agree with about 95% of it, but after I read it, I thought I had to buy 85 new things and make 300 recipes from scratch every week. In all of this, I don't want anyone to feel like a burden is being put on them. Listen for the Shepherd's voice. We can avoid legalism and be wise stewards of the home and family for which God is entrusting to our care.
We may spend more on equipment or higher-priced health food items. But we may also spend less on the processed food we used to buy. You may decide to make some sacrifices so that you can afford what you need...eating at home more, avoiding that Starbuck's stop, or packing lunches instead of picking something up. If Jesus is calling you to make changes, he will help you see what can be done to make the changes possible. He wouldn't ask you to do something and then make it impossible to do!
I got a little off-topic but maybe someone needed to hear the rambling! Anyway, my personal opinion is that the best gadget to improve your family's health is a grain mill. Most all meals contain grain of some type in them and if it's store-bought (with the exception of the Ezekiel brand), it's probably not healthy. You may be amazed at how far you can stretch a meal by adding a bread product like rolls, breads, or muffins.
You can take the bread recipe here and make it into a hundred different things, so that you can just get in the habit of making bread dough every day or every other day and you will find that you don't have to think so much before meals. I usually make the dough and use half of it for an everyday loaf (sandwiches, toast, etc.) and the other half for pizza dough or rolls or whatever. Pretty soon, it will be as mindless as brushing your teeth.
If you ever want to try mine, let me know. Homemade bread products are my family's favorite part about a whole foods diet!
