It depends. And i don’t know if there’s enough research about GMO vs organic long term benefits. Grains have been crossbreed for decades naturally, is speeding that up or modifying tomatoes with fish or other dna so they don’t freeze in the refrigerator healthy?
Also many large stores pick fruits and vegetables when they’re not ripe yet before they’re shipped to the stores. They spray them with nitrogen to ripen and look the color they’re supposed to be, but that last stage of growth is where all the nutrition comes from.
If you can’t buy local produce, i supplement my nutrition. If you want to talk more about supplements, i can rant there too.
Local isn’t always more expensive. In season produce is also better IMO.
