Core Tip

Core tip: Over and above a low calorie diet to assist with weight loss, specific foods may modify the course of Non-alcoholic fatty liver disease. Two or more serves of oily fish per week has a beneficial effect on lipids and may reduce hepatic steatosis, regular filtered unsweetened coffee is associated with reduced fibrosis severity in non-alcoholic steatohepatitis and a handful of nuts per day improves liver function tests. Addition of avocado and olive oil to the diet is associated with weight loss and improved liver tests while moderate consumption of tea and red wine appears safe.
