A new study shows that formula-fed babies had higher arsenic levels in their systems than those who were breastfed.

Researchers at Dartmouth College measured arsenic in tap water, in breast milk and in the urine from dozens of 6-week-old infants. They found that arsenic in the urine of breast-fed infants was seven times lower than in formula-fed infants.

They say tap water used to mix formula was mostly to blame. But the powder also contributed to the levels.

The study's authors say that in large doses, arsenic can lead to serious health problems.

Eat well, eat soon

To get more bang out of your breakfast, experts say eat within an hour of waking up.

That allows your body to take full advantage of its fat-burning potential.

Breakfast should include good protein such as eggs and Greek yogurt. And a banana to help burn fat for energy.

Super bug lawsuits filed

The first lawsuit related to "superbug" infections at UCLA Hospital was filed this week.

The suit is against the manufacturer of endoscopic equipment, not the hospital.

Nearly 200 people were exposed to the antibiotic-resistant bacteria CRE through endoscopic tubes. Seven people were infected, two of whom died.
