Ah, a Breath of Lemon-Fresh Air

Does a flight of stairs leave you winded and a little worried about your lungs?
Try squeezing a lemon.
A cold glass of lemonade may protect your lungs against a potentially serious condition: adult asthma.

In fact, adding all things citrus -- grapefruit, oranges, lemons, limes -- to your shopping list may help reduce your risk of developing this respiratory bane, regardless of how active or how old you are.

Like most fruit, citrus is packed with nutrients that can help keep you healthy in general.

And the ample amount of vitamin C in citrus fruit may have a particular benefit: reduced risk of asthma.

In a recent study, adults who ate little or no fruit and shunned citrus were significantly more likely to have the wheezing, gasping symptoms of asthma. So don't skip your morning OJ.
