You're trying to watch your weight, so you always check the calorie count on the Nutrition Facts label. That's a good start, but you could be misled by that number, unless you check the serving size listed for that package.
Jayne Hurley, senior nutritionist with the Center for Science in the Public Interest tells me those serving sizes were developed in the 1970s.
"Unfortunately, those serving sizes don't reflect what people typically eat now," she said.
For example, the FDA says a serving of ice cream is 4 oz., the size of two golf balls. Seriously?
Hurley says smart shoppers need to do check the serving size and do the math.
"See if that matches what you eat," she explained. "If it doesn't, you need to double, triple, quadruple, whatever those numbers are to reflect the service size that you're eating."
Here’s a tip about cereal. The serving size listed on the label for cereals that are dense, such as granola, Grape-nuts or muesli, is much smaller than with flakes – just a 1/2 cup. So watch out for that.
