Is irradiated food as nutritious?
« on: 13/04/2014 02:30:01 »
Rosemary Bunnage <> asked the Naked Scientists:
   
If food has undergone radiation, does it still have the same nutrients as food freshly picked? And for how long? I have been told the jury is still out on this.

Many thanks
RoseB


What do you think?

I don't like it particularly. On the other hand that is a mostly emotional response as I prefer fresh food. But it will probably stop me from buying irradiated food, presuming it is declared to be irradiated, that is :) The food industry seem to have all kinds of tricks hiding what's in ones pre-prepared food those days.

As for the rest of your question? Don't think it will change the chemistry of the food, but I can't be sure, can I? https://en.wikipedia.org/wiki/Food_irradiation

My only concern would be that radiation sterilisation would be used to try and hide the spoiling of food stuffs prior to its use although these should be easily detected.
I feel that its use would be much better than processes such as adding salts or nitrates many of which may well be carcinogenic.
As for nutrition the only doubts that I have are the possible loss of vitamins but this is much less than normal cooking.

The movement of food from North to South or from South to North improves the nutrient availability during in the off season.   

Invasive species, however, are a HUGE problem. 

Perhaps we should look at food irradiation as improving nutritional availability, while protecting or local agriculture.
