Yes and it’s less tasty too. GMO ruined it.

Very few foods are genetically modified and those modifications have nothing to do with taste or nutrition, but pest and pest control resistance.

Foods have been bred for shelf stability and size which leads to less flavor and nutrition.

This sparks an interest of mine. I want to grow my own garden of fruits and vegetables. I can grab seeds from my local hardware store. But are these genetically the best I can buy? Is there not a genetic strain of seeds that I can buy somewhere else, perhaps online, that produce both the most nutritious and delicious?

I don’t know about “genetically best” but you can check out heirloom seeds from houses like the seed savers exchange (And many others) https://www.seedsavers.org/

Thank you. I think this gets me in the right direction. "heirloom seeds" seems to be what I am looking for. Some online testify that they find heirlooms taste better. I'll have to do some more research and try them myself to see if its true.

National Geographic has really gone to crap.

”One of the largest scientific studies to draw attention to this issue was published in the December 2004 issue of the Journal of the American College of Nutrition.”

And what did that paper conclude?

“Conclusion: We suggest that any real declines are generally most easily explained by changes in cultivated varieties between 1950 and 1999, in which there may be trade-offs between yield and nutrient content.”

Nothing about “loss of mother earth’s soil nutrients”. But that wouldn’t sell ads would it?

They are also more abundant than they used to be and that's a valid tradeoff to consider. Would it be worth it to only have access to seasonal produce local to your region for that produce testing better? Make do with pickles and potatoes instead of fresh fruit and vegetables in late fall through early spring? If not, shelf life, productivity and greenhouse feasibility are relevant metrics in addition to taste and vitamins. Old ways of gardening are still available, but most people will end up using these as a supplement rather than replacement to supermarket food that is at least always there in sufficient amounts.

Earlier quoted context omitted.

My understanding is actually that it was ruined by artificial fertilizer and monoculture, because those nutrients are drawn from the soil, and we only "feed" plants the nutrients required to grow and no other trace minerals. Eventually the soil becomes depleted and this causes them to be less nutritious. Taste is affected similarly because we essentially chemically treat plants to make them take on more water and wat…

Yup this is exactly it. I don't think the issue is that our fruit is larger, but just that the soil is much more degraded. 90-95% of all plant species get the MAJORITY of their nutrients from mycorrhizal associations and some, like many orchids, are even obligate. Plant roots are generally primarily meant for communication and connection with fungi, not to extract nutrients from soil. But when practicing monoculture,…

If I understand correctly this is why aquaponics delivers more nutritious and better tasting veggies, along with less fighting against pests(?)

This article mentions that regenerative agriculture as the solution. There is a lot of concern now about the potential for a global food shortage at the end of this year because of rising fertilizer prices (leading to less planting). Regenerative agriculture can help solve this as well by focusing on restoring the biome of the soil, thereby harnessing nitrogen from the air and minerals from the soil.

not like they had to reach for straws to write that story anyway - there is an interesting, nuanced narrative to be told on the haber-bosch processes influence on food prices and the practices of industrial agriculture, particularly tilling. we used to grow food in soil, now we grow it in dirt.

The issue at the heart of this is soil quality, not the genes of the crops.

Anything you grow in your garden will likely be better out the gate. Doubly so if you compost.
