When you hear about living a healthy lifestyle, you may hear a lot about heart health. However, the organ less advertised for its importance is the liver. The liver is important since it filters toxins from your body to protect it from harm. A diseased liver, which can be caused by excess weight, alcohol abuse, or viruses like hepatitis, can cause many serious health problems. Therefore, it is key to keep your liver healthy by maintaining a healthy weight and avoiding substances such as alcohol and drugs.
