Another Study Suggests Too Much Fish Oil Could Trigger A-Fib

A new study confirms that fish oil supplements may raise the risk of a common heart-rhythm disorder -- particularly when doses top 1 gram per day.

Omega-3s From Fish Might Curb Asthma in Kids, But Genes Matter

Consuming greater amounts of certain omega-3 fatty acids found in fish may reduce the risk of asthma in kids -- but only those with a common gene variant, British researchers say.

"Asthma is the most common chronic cond...

High-Dose Vitamin D Won't Prevent Seniors' Falls: Study

High doses of vitamin D may increase seniors' risk of falls, rather than reduce it, according to a new study.
