A reader asks: Does day-old, leftover kale salad have less nutritional value than kale that is fresher?
A reader asked the NYT Food blog whether day-old kale is less nutritious. While the answer is—technically-speaking—yes. The author goes on to note what really matters when it comes to maximizing nutrients: temperature.
Whether the leftover kale is raw or cooked, dressed or not, it’s important to keep it refrigerated. One study found that after six days of refrigeration, leafy vegetables lost only 10 percent of their vitamin C content (versus 20 percent in just two days at room temperature).
Thanks for clearing that up for us, NYT!
