Nonalcoholic Fatty Liver Disease Nutrition Therapy
What is nonalcoholic fatty liver disease?
Nonalcoholic fatty liver disease (NAFLD) or "fatty liver" is a liver disease that progresses slowly over time. It starts when fat builds up inside the liver. Over time, too much fat stays in the liver and may result in more severe conditions, such as cirrhosis. NAFLD usually develops in children and teenagers who are overweight or gain too much weight. Most of the time, fatty liver occurs with other health problems such as pre- diabetes, insulin resistance or high triglycerides.
How is NAFLD diagnosed?
- Blood tests (liver enzymes) to see if there is liver damage and to rule out other causes of your child's liver problems
- Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) are both common liver enzymes. When there is damage or inflammation in the liver, these numbers usually go up.
- AST and ALT are not specific to one disease and can be high from many different types of liver problems. More testing is usually needed to figure out what caused the elevation in the liver enzymes.
- Ultrasound of liver to look for fat or other abnormalities in the liver
How is NAFLD treated?
Children with NAFLD benefit the most from stopping their weight gain. We encourage children and their families to follow key health behaviors:
- Avoid sugary drinks and other sugary/sweet snacks, chips, etc.
- Drink mostly water and some low-fat milk
- Aim for at least 60 minutes of physical activity every day
- Limit TV and screen time to one hour or less per day
- Make half your plate vegetables at mealtimes
- Eat breakfast every day
- Add more lean protein to each meal
- Lower intake of carbohydrate-heavy food items (bread, rice, pasta, tortillas, etc.) by keeping portions small and opting for whole grain versions
What can I do to help my child?
Work together as a family to improve your healthy habits. Small changes can make a big difference over time.

- Continue to add healthy changes over the coming weeks and months
