Recently I watched a woman set a carton of Land O' Lakes Fat-Free Half-and-Half on the conveyor belt at a supermarket.
"Can I ask you why you're buying fat-free half-and-half?" I said. Half-and-half is defined by its fat content: about 10 percent, more than milk, less than cream.
"Because it's fat-free?" she responded.
"Do you know what they replace the fat with?" I asked.
"Hmm," she said, then lifted the carton and read the second ingredient on the label after skim milk: "Corn syrup." She frowned at me. Then she set the carton back on the conveyor belt to be scanned along with the rest of her groceries.
The woman apparently hadn't even thought to ask herself that question but instead accepted the common belief that fat, an essential part of our diet, should be avoided whenever possible.
