Recounting Calories

In this June 22, 2019 file photo, a shopkeeper weighs California almonds for a customer at a shop in New Delhi, India. Almonds used to have about 170 calories per serving, then researchers said it was really more like 130. A little later, they said the nuts may have even less. The shifting numbers for almonds show how the figures stamped on nutrition labels may not be as precise as they seem. (AP Photo/Altaf Qadri)
