nostr:npub1t3pjtms82njzz9l8fh22nsrjlkwpnunseyntv6umt63h8ckk572sgqxdwy I spend about $1200/month to feed two adults and 4 boys under 5 years old (The baby is nursing).

We buy a lot of organic food, and a lot of meat, eggs, and milk. 
I think if you didn't want to spend more for healthier food, you could buy cheaper ingredients, cook for yourself and spend ~$7-800 for a family of 4, with not dining out, but of course one parent has to stay home and cook/meal plan.
