Variety is more important than homegrown v store bought. As with eggs, if you buy production breed chickens and you feed those chickens the same stuff the commercial sector do, your eggs will be like commercial sector eggs. If you keep traditional breeds and let them eat traditional foods, you will see and taste the difference between shop bought and home grown eggs.
I have seen the differences in my backyard flock eggs. My chickens get to scratch and peck through chicken compost all day, eating bugs and worms. They also get grass clippings, leftover food, and kitchen scraps. My egg yolks are a darker orange than the pale-yellow yolk store bought eggs.
I can see the difference in the color of the yolks at home. I probably just convince myself the home-grown eggs taste better. The people we sell our excess eggs are convinced they look and taste better than store bought eggs. That's good enough for me.
I don't doubt that big ag will find a way to pretend to be it soon, but I don't think they've got there yet. They have captured the organic label, which is why many truly organic growers have left those schemes.
Maybe that's like "organic" eggs which cost a fortune where I live. Seems like only the big guys can afford that certification. My backyard flock has a good life, outside most of the day in the non-snow months. But I can see a large poultry business keeping their chickens locked in cages and feeding them "organic" feed to get some kind of certification.
The "organic" feed where I live is about 2X the cost of commercial chicken feed. I can't afford that. And, honestly, I don't believe it's necessary. I'm happy with our fresh eggs from our backyard flock.
It depends on who is certifying the food, there is organic and then there is organic, I was shocked when I found out that some "organic certifiers" allow up to 20% petrochemicals and/or GMO's in the food that they are certifying. There are a few good certifiers but unfortunately it is the bad ones that make people say that organic food is just a rip off.
Yeah, I find that shocking as well.
I don't want to say that organic food is a rip off, but I can't say it's really any better either. I rarely pay extra for organic foods. Every once in a while, our local
WalMart will have a sale on excess organic food that they discount to move out before it goes bad. I bought some organic bananas on sale for less than the non-organic bananas.

They tasted the same to me. I'm not convinced they had more nutrition in them and worth the extra money.
