The Whole Grain Stamp, used throughout the food industry, is a good sign, but it’s not a barometer of a food’s health value. Whole grains lower your risk of heart disease, weight gain, and type 2 diabetes, as compared to refined grains, like white flour, so you should look for foods with whole grains. But when a team of researchers scoured the nutrition labels of 545 whole grain breads, cereals, granola bars and chips, they found that they were higher in fiber and lower in trans fats, compared to foods without the stamp, but had more sugar and calories.
Don’t rely on the stamp! Check the label and go for products with a ratio of total carbs to fiber of 10 to 1 or less.
