I’ve also come across indication that beta carotene byproducts can potentially inhibit vitamin A use (also likely connected with personal genetics), throwing another wrench into the works.
Basically I do not recommend naively conflating carotenoid intake with vitamin A intake, especially in regards to populations vulnerable to malnutrition. For me and most of you reading this however the difference is not much of consequence.
I’m obviously fine with genetic modification to plants to create crossbreeds of various types of, say, lettuce, but it seems like we are trying to change out plants instead of trying to change our farming practices.

Edit: since people are likely looking for a citation here, and are likely to down by default (again, I don't think their is anything "wrong" or "unhealthy" about genetically modification), I'll add one of his papers on the subject. Again, the concern is only to do with the effects that significant modification could have on wild species, and not on consumption:

>Genetically Modified Organisms (GMOs) and their risk are currently the subject of debate. Here we argue that they fall squarely under the PP [Precautionary Principle] because their risk is systemic. There are two aspects of systemic risk, the widespread impact on the ecosystem and the widespread impact on health.
>Ecologically, in addition to intentional cultivation, GMOs have the propensity to spread uncontrollably, and thus their risks cannot be localized. The cross-breeding of wild-type plants with genetically modified ones prevents their disentangling, leading to irreversible system-wide effects with unknown downsides. The ecological implications of releasing modified organisms into the wild are not tested empirically before release.
As a fancy product provides a new color in the market and can bring the company a lot of money (I'm not against that as long as is grow accurately) but IMO must be cleaned thoroughly by the consumer.

The best lettuce has 2.5mg of beta-carotene in 47g of lettuce. The best sweet potato has 31mg of beta-carotene in 328g of sweet potato (sweet potatoes are the beta-carotene leader BTW :strong:).
If this modified lettuce can really have 30 times as much beta-carotene, that's a significant amount. I was expecting the numbers to show that lettuce had almost no beta-carotene, and after you times it by 30 it's still almost nothing, but apparently it's more significant than that.
