Egg yolks are indeed full of cholesterol. Like most cholesterol-rich foods, they are jam-packed full of important nutrients, especially the fat-soluble vitamins and essential fatty acids. In fact, the slew of nutrients in an egg yolk is so comprehensive that a few a day would offer better insurance than a multi-vitamin.
In the United States, approximately 7% of households are millionaires.[7] A 2010 study argues that millionaires (those in the top 1% of earners) pay approximately 40% of all taxes in the United States.[4] According to the book The Millionaire Next Door, only 20% of millionaires inherited their wealth.
America continues to get heavier. An analysis of data collected from 2007 to 2012 has found that 71 percent of Americans are obese or overweight. The picture is slightly worse for men, three-fourths of whom are overweight or obese. About 67 percent of women fall into one of those two categories. In all, nearly 35 percent of Americans are overweight, meaning that they have a body mass index between 25 and 29.9. This metric is a generally reliable way of estimating body fat percentage, though it can overestimate fat in athletes and those with a particularly muscular build.
