Keep your liver healthy

A healthy liver plays a vital role in digesting the food you eat and the nutrients you absorb and rids your body of toxic substances. It is important to take steps to protect this vital organ as you age.

Here are few tips:

1) Take medications sparingly Use prescription and over-the-counter drugs only when you need them and take only the recommended doses. Too many medications can be damaging to the liver.

2) Don't mix meds and alcohol Certain drugs, such as acetaminophen, can be toxic to the liver when consumed with alcohol.

3) Keep weight in check Obesity can cause a condition called nonalcoholic fatty liver disease. Experts say the most effective diet is rich in fiber and low in calories and saturated fat.

4) You are what you eat Remember all the food and beverages you are consuming pass through your liver, so the healthier the food, the healthier your liver will be. Strive to eat several servings of fruits and vegetables daily.

If you feel fatigue or have a dull pain in your upper right abdomen, it could be an early sign of liver disease. Consult your doctor for proper screening.
