By the numbers: The massive toll of the Animas River spill

Image

Three million gallons of heavy-metal filled waste water spilled into the EPA spill turns Animas River orangeAnimas River as the result of a leak during the treatment of contaminated water in Gold King mine in southern Colorado. The EPA has taken full responsibility for the spill. The spill, which caused the river to turn yellow, crossed multiple state lines. A water sample taken briefly after the accident noted that lead levels in the water were 12,000 times higher than normal, and contained very high levels of arsenic, cadmium, beryllium and mercury as well.

The states most affected by the spill are Colorado, New Mexico, and Utah. Attorney generals of those states have suggested they might pursue litigation individually or collectively, though it is too early to determine whether it is appropriate. More>>

A Few Tweaks to Amp Up Your Workout

Change up your exercise routineSpringtime is a great time to revitalize your workout to get the health results you have been aiming for. When it comes to maximizing your work out, variation is key.

This ultimately makes losing weight and maintaining fitness more difficult. A study from the University of Florida also indicates that people who do the same work out are less likely to continue exercising. The same study indicates that to alleviate mental fatigue and boredom, workouts should be modified every two weeks. This change allows people to remain interested in their exercise routine and are thus more likely to follow through with their fitness goals.

Ways to change up your workout include incorporating strength training, changing location, and the intensity of your workout. More >>

Dietary Cholesterol Not “A Nutrient of Concern”

The Dietary Guidelines Advisory Committee reports thatsix-eggs-in-carton dietary cholesterol is not a source of concern for overconsumption. Dietary cholesterol – found in foods such as eggs, shrimp, and butter – was placed in the “foods and food components to reduce” category in the 2010 guidelines. Current recommendations advise consuming less than 300mg per day; a single egg contains about 164mg. Should the suggestions be adopted by the USDA and the US Department of Human Services, it could radically change the way Americans perceived their dietary choices.

Research indicates that the dietary cholesterol in food has little to do with cholesterol levels in the blood. The evidence linking heart health and saturated and trans fats is much stronger, as well as the cholesterol reducing effects of eating whole grains. More>>
