A press release today from the Organic Center announces publication of a major study by Brian Halweil examining changes in nutrient levels of farmed crops in the United States. Halweil summarizes evidence that food crops are less nutritious now than they used to be and that organic crops are more nutritious than conventional. While such findings seem intuitively obvious, they are very difficult to prove. For one thing, methods for evaluating the nutritional content of foods were not as accurate 50 years ago as they are now. For another, the samples may not really be comparable. Even so, this report is worth having for addressing the questions in a serious way. Read and enjoy!
I am speaking at the Con Edison Science, Technology, Energy, Environment, and Math (STEEM) Distinguished Lecturer series on “Food Politics 2020: Food Industry Influence on Nutrition Research and Practice.” It’s from 12:15-1:30 pm at the Science Building, C-201. Details are here.
