Food Fact:
Why drink water?


Your body is 60% water -- and not drinking enough can wreak havoc from head to toe. Up to half of all Americans suffer chronic mild dehydration that can cause fatigue, headache, loss of appetite, dry eyes and mouth. As we age, thirst becomes a less sensitive indicator of dehydration, so don't wait until you're thirsty to grab a glass. If you work out, drink more during intense physical activity, when dehydration is a real threat -- your body rapidly loses water through sweat and vapor in exhaled air. A rapid water loss of 5% of body weight can reduce muscular work by 20 - 30%.

Fitness Tip of the day:
Walk it off.


Who needs special training or fancy gear to tone up your body and perk up your frame of mind? All it takes is your own two feet. Research shows that just 20 minutes a day of brisk walking will lower your risk of serious diseases -- that's just four five-minute walks a day! A half-hour a day is even healthier. Walk 45 minutes a day, and watch your waistline shrink.

FAQ of the day:
What is "good" and "bad" cholesterol?


There are two kinds of cholesterol carriers in the blood: HDLs (high-density lipoproteins) and LDLs (low-density lipoproteins). They are also commonly referred to as "good" and "bad" cholesterol -- to remember which is which, think "H" for Healthy and "L" for Lousy. Another tip: Keep the bad LDLs "Low," because their cholesterol ends up in arterial plaques, while you want the good HDLs "High," because they carry cholesterol away from arteries. A desirable level for LDL cholesterol is less than 130 mg/dL. For HDL, a level below 40 mg/dL increases risk, while 60 mg/dL or higher protects against heart disease.
