Also - pick up a copy of the Vitamin Bible by Earl Mindell. I'm not recommending the supplements, but it covers side effects if you are deficient, as well as natural sources for various vitamins, minerals and herbs. I found depression is probably more often nutrient deficiencies - stress, caffeine, excess sugar, alcohol and cigarettes all destroy the nutrients needed to produce neurotransmitters, leading to depression, trouble sleeping, sexual dysfunction, and much more. As mentioned elsewhere, a nutrient deficiency such as magnesium can have a domino effect.
Wheat farmers started spraying the wheat fields prior to harvest; the wilted plants are easier to cut/harvest and the dying plants kick out a few extra seeds. However the Roundup (glyphosphate) residue contaminates the wheat. Most people are actually reacting to the poison, not necessarily to gluten.
Try ketchup, tomato paste and BBQ sauce - to go with pasta, sandwiches etc. First time I made ketchup I was in heaven!
I pay about $20/pint for organic raw honey. Seriously considering a hive, as bees are in seriously short supply here - last year's garden had trouble, very few cukes, zucchini, squash or tomatoes. Did things to attract pollinators with very little luck - too many big farms in the area, I'm guessing!
If SHTF those bees could come in handy; wax can be used to seal jars of food.
Not enough acreage in many cases for pasture rotation. We have about 8.5 acres - but some is wooded/old stream bed, plus land the house sits on and the workshop. Mares are off hay for the summer, but pasture doesn't produce enough during the winter without supplementing with hay.
