This process allows the digestive system to better break down fats into smaller, more easily absorbed molecules.As I read through my newspaper this morning, I came across an

But there's good news! VietNam and South Korea are both moving to eliminate the harvest of bear bile. Hopefully, the Chinese government will follow their lead.
