High cholesterol causes cardiovascular disease. Eggs are high in cholesterol; a large egg contains about 210mg of the stuff, which is concentrated in the yolk. The American Heart Association has recommended that people limit their daily cholesterol consumption to less than 300mg to maintain heart health [1]. Thus, it would seem that we should eat fewer eggs, or at least fewer egg yolks, to prevent cardiovascular disease. Right?
Statins, including Pfizer Inc.’s Lipitor, are among the most prescribed drug in the world, and are currently routinely taken by millions of Americans. They are indicated for people with high blood pressure and/or high cholesterol, and have been shown to significantly reduce the risk of heart disease, heart attack, and stroke in this population. Yet the FDA has just issued new warnings concerning potential side effects: elevated blood sugar, which is a risk factor for developing type 2 diabetes, and cognitive impairment such as memory loss. The warnings will not be affixed to the outside of the bottle, but will be included in the package insert that comes with all prescription medications.
According to the USDA, as of March 1, most meat and poultry products in the U.S. will have nutrition labels [1]. The rule applies to ground and chopped meat and poultry, plus the most popular cuts of raw meat and poultry. The aim of the new requirement is to give consumers access to information that aids in making healthy choices.

It’s certainly true that the U.S. has a problem with body fat; according to the U.S. Centers for Disease Control and Prevention (CDC), about two-thirds of adults in the U.S. are overweight, and fully one-third of adults fall into the more serious “obese” category [1]. Still, appropriate amounts of body fat serve valuable roles. These include helping to maintain the immune system and nervous system, protecting body organs and padding areas where the skeleton would otherwise put pressure directly on the skin (such as the soles of the feet).
Too much body fat, however, is associated with a number of negative health effects, including increased risk of heart disease, type 2 diabetes, arthritis, and apnea.
