I thought the mRNA piece was really interesting thinking of the potential of future medical treatments, obviously lots more work needs to be done. I
was also wondering to get to the kind of levels of mRNA concentration required to affect expression consistently, how much rice would the mice have to
eat on a daily basis? What would be the equivalent situation in humans?
Obviously if only one protein isn't transcribed in a cell, that's not a big deal. During fetal development critical development occurs in very small
time windows with very small amounts of hormones... it's definitely an area worth lots more research.
In the case of a busy American's diets full of processed food, the diet will be mostly consisting of Corn / Soy & Canola (the main GMO's).. Try
finding processed products on the supermarket shelves that don't contain these ingredients!
Would these amounts produce significant amounts of mRNA that affect anything, especially during fetal development ?
Apparently the average American consumes over 4lbs on corn per day.
In order of diminishing corniness, this is how the laboratory measured our meal: soda (100% corn), milk shake (78%), salad dressing (65%), chicken
nuggets (56%), cheeseburger (52%) and French fries (23%). What in the eyes of the omnivore looks like a meal of impressive variety turns out, when
viewed through the eyes of the mass spectrometer, to be the meal of a far more specialized kind of eater.
Today, an alarming 60% of the food on America's supermarket shelves contains soy derivatives (i.e. soy flour, textured vegetable protein, partially
hydrogenated soy bean oil, soy protein isolate). When you look at the ingredients list, and really look at the contents of the "Average American
Diet," from snack foods and fast foods to pre-packaged frozen meals, soy plays a major role.
Yes agreed that Organic does better in developing countries due to resource issues for the small farmers, but also due to the environmental conditions
(availability of water for irrigation, the high diversity in slope and soil types ), especially in parts of Africa where commercial monoculture
intensive farming just destroys the soil and has increased costs of agro chemicals. (The Govt's there are far less able to subsidize the way we do).
The other thing to say about Organic farming is it requires greater expertise from the Farmer (experienced farmers in organic studies get much better
yields, sometimes even in excess of conventional techniques) and to be truly sustainable needs to be mixed with animal husbandry. Also given peak oil
production occurred around 2006 we need to wean ourselves aware from petroleum based agriculture.
I personally favor traditional plant / animal husbandry instead of genetic engineering; after all look at the amazing yields of IR8 rice.
Given the rate of population growth has steadily been falling since the 1970's and Human fertility rates are also decreasing steadily I do not think
we are going to have a food issue, unless we keep losing diversity in our food crops and their wild relatives. Yes climate change may force us to grow
different crops but it's not as if we do not have the knowledge of what grows where.
I do think we should keep doing the genetic research to understand the world around us and to only use "commercially" in the larger environment when
we truly know what we are doing. I would feel much happier if we could insert gene's or better still alter existing gene's expression with targeted
precision... but that's just me.
