My eating habits are not terrible but they could be better but I have notice that some healthy alternatives are expensive. I'm looking for some ideas on healthy food choices that are reasonably affordable.
Well, when on a budget. You should prioritize protein. On the cheap, beef is king. Canned tuna is a buck. I mean the term "health food" is very ambiguous if you ask me. Here's an article you can read.
Brown rice, beans (dried is cheapest)
Canned tuna & chicken
Flour is super cheap and you can make seitan, or wheat gluten protein, with just water and some seasoning. Look it up.
Eggs. (i used to fry up onions and whatever veggie i had and put that and fried eggs on top of some brown rice with a lil butter and seasoned salt for two meals a day)
I think it's best to buy healthy foods with a good shelf life. It's great when your check doesn't stretch as far as you'd hope.
Frozen vegetables last longer and are sometimes cheaper than fresh vegetables. I like frozen mixed vegetables because of the taste and versatility.
Apples and citrus fruits are good too. They last a while and are fairly cheap.
I also buy basic wheat bread, pasta, and peanut butter.
Here are some of my favorite lists:
This is a basic list. It's the best list I've found, with over 80 foods.
