The Lancet on the nutritional value of organic food
"Those who have criticised the review perhaps do not know enough about what a systematic review is. Because the review set out to look at nutrient content only, it is wrong to point out that it did not include analysis of pesticides, herbicides, or fungicides. Nor did the review attempt to look at taste and freshness, food miles, animal welfare, biodiversity, or sustainability.
If one wants to buy organic food, do so because it might be fresher and taste better, contains far less chemical residues, and is kinder to farmed animals."
