Perhaps the biggest change this year could breathe some life into your breakfast habits: The cholesterol in egg yolks is no longer as much of a health concern. The US Dietary Guidelines used to recommend that you eat no more than 300 milligrams of dietary cholesterol a day, or under two large eggs. But this year, the committee has scrapped that advice as new research suggests that the cholesterol you consume in our diets has little to do with your blood cholesterol. Saturated fats and trans fats, on the other hand, could boost your blood cholesterol levels, as could unlucky genes.
