Rice and potatoes fine for daily use.
Corn is high in fungal toxins depending on the source. The hulls wreck my gut so I pass.
Peanuts are high in allergenic protein, omega-6 fat, and fungal toxins. Individual reactions vary of course.
CAFO beef is okay but I'd drain the fat.
Stretching protein with starch is good budget sense assuming no (pre)diabetes etc. I'd also make stews with connective cuts (shanks, tails, shoulder chops, hearts, turkey necks) and bulk it up with humble absorbent vegetables like onions, cabbage, carrots, celery, turnips, cauliflower, white mushrooms, and chayote. Dried peas are pretty harmless too. Each bite will taste protein-y.
Some canned seafood like mackerel are amazing protein/dollar too.
Fruit prices fluctuate wildly with the season, watch the promotions.
Check local prices for things like cassava and plantains. They might be more $/lb. than Russets but they're also more dense.
