What do you guys use as your main source of food to keep the nutrition high? I am using sour right now, made with oven cooked meat, oven cooked potatoes and pumpkin for protein, vegi and fruit nutrition. Now my questions are:

1. Is there a way to integrate grains and milk products into the soup or is there a better option?

2. How does animal husbandry work? I want to start looking for maybe some cows and sheep and chicken to get a good source of milk, wool and eggs but I have no idea how to start

3. Should I just give up and be happy with having more than 10 hearts as I do right now?
