Eating a healthy diet is important, but do you need to eat only healthy foods at every meal and every single day? Isn't a treat now and then OK? I certainly think so, and the Academy of Nutrition and Dietetics (AND) also supports the idea of eating certain foods in moderation. That means it's okay to eat something that isn't good for you as long as you only eat a small amount and/or not very often.
Visible at the top of the Hoover Dam, this 'bathtub ring' shows the devastating effects of a drought which has seen the level of Lake Mead drop to an historic low. The lake's surface now sits at just over 1,000ft, the lowest point it has been since it started being filled in the early 1930s when the dam was finished.
The recently opened Hoover Dam Bypass Bridge, in background, diverts traffic around the crest of the dam. Physically, Hoover Dam is a massive, concrete arch-gravity dam, 660 feet thick at its base and wide enough at its crest that traffic on old U.S. 93 coursed right over its top.
