Depending on the body of water and the type of fish you are eating, you might need to worry about environmental pollutants. Many jurisdictions publish guidelines about which fish to avoid eating due to accumulated mercury or other chemicals.
It can be a super cheap way to supplement your diet, though. The biggest investment will be your time. Use a second-hand rod or even a cane pole with no reel. For bait, dig up earthworms.
Seconding. I learned recently on a camping trip that the Rio Grande has high mercury levels in some places, so much that more than two fish will typically put you over the danger threshold
