Lambert comments on the depletion of nutrition in fruit and vegetables. High-yielding crops produce more load, more rapidly but they can't make or absorb nutrients at the same pace, so the nutrition is diluted. But the idea that modern agriculture produces crops that are less nourishing remains controversial, and "then and now" nutritional comparisons have been much criticized. The differences found may be down to older, less accurate methods of assessing nutrition, and nutrient levels can vary widely according to the variety of plant, the year of harvest and the time of harvest.
