Guest Theo Posted November 23, 2013 Report Share Posted November 23, 2013 Does anyone have any solid info on the nutritional quality of non-frozen vegetables bought pre-chopped? One often hears that there is massive nutrient loss, but I'm not sure if this claim has any real scientific validity. I couldn't find anything on PubMed, but I did find this reference to a article published in the Journal of Nutrition. http://nutrition.about.com/od/askyournutritionist/f/cutveg.htm If true, the level of nutrient loss described (at least on this web page) strike me as a pretty reasonable tradeoff for the convenience gained: a 10 to 25% nutrient loss spread out over the time it takes for the vegetables to become basically inedible anyway. On the other hand there's this: http://www.japantoday.com/category/health/view/are-pre-cut-vegetables-doing-our-bodies-more-harm-than-good Which suggests that while buying pre-cut vegetables isn't necessarily a bad, it is important to look at how the "fresh" food may have been chemically treated. Oh, and if anyone has any specific info on this, I would be particularly interested in B-group vitamin loss in pre-choped mushrooms! Link to comment Share on other sites More sharing options...
