Because the liver is a digestive organ, diet plays a major role in its health. A healthy, balanced diet and a healthy body weight are conducive to liver health, and unbalanced, hypercaloric diets (especially ones that increase risk of metabolic syndrome) are not. Fat intake may influence the risk of nonalcoholic fatty liver disease, but fat type and total calorie intake matter.[1] Also, limited evidence has found an association between increased consumption of coffee and nuts and reduced liver disease.[2]
