Drinks to Avoid with Fatty Liver: 7 to Limit

With fatty liver, avoid alcohol and limit sugar-sweetened soda and sweetened energy drinks.

Other drinks with substantial amounts of sugar can also make it harder to manage fatty liver, particularly when they are consumed regularly. The right choice depends on what is in the drink, how much you have and your overall health. For alternatives, see the best drinks for fatty liver.

The evidence linking specific drinks to fatty liver is limited. Much of the research below concerns children or dietary patterns rather than trials showing that avoiding one particular drink improves fatty liver in adults.

Which 7 drinks should you avoid or limit with fatty liver?

1. Alcoholic drinks

Alcohol can injure liver cells and contribute to liver inflammation and scarring. It can also worsen liver disease when fatty liver is already present, regardless of whether the drink is beer, wine or spirits.

Avoiding alcohol is the safest choice for fatty liver, especially if you have advanced liver scarring or cirrhosis. Ask your clinician for advice based on your diagnosis and drinking history. If you drink heavily or every day, seek medical advice before stopping abruptly: alcohol withdrawal can be dangerous.

The two reviews we found focus on sweetened beverages, not alcohol treatment trials. The advice to avoid alcohol is a precaution based on its established potential to harm the liver, not a claim that these reviews tested alcohol avoidance.

2. Sugar-sweetened soda

Regular soda can supply a substantial amount of added sugar without much nutritional value. Frequently consuming excess calories can contribute to weight gain and liver fat, while the liver's processing of fructose is one possible pathway linking high sugar intake with fatty liver.

Limit regular soda, including flavored varieties and sweetened fizzy drinks. Check the added sugars in grams on the label and the number of servings in the container; the sugar listed for one serving may not describe the whole bottle.

A 2016 review of beverages and fatty liver in children identified high sugar and calorie consumption as concerns and recommended reducing soft drinks. It does not establish how much soda causes fatty liver in an individual or prove that avoiding it alone reverses the condition.

3. Sweetened energy drinks

Sweetened energy drinks can add both sugar and calories to the diet. Their caffeine content is a separate concern, particularly for children and people sensitive to caffeine; it should not be confused with the sugar-related concern for fatty liver.

Check the label rather than assuming that an energy drink is sugar-free. Limit sweetened versions, and discuss energy drink use with a clinician if you have a health condition or take medication. Children and adolescents should avoid energy drinks.

The 2016 pediatric review included energy drinks among the beverages it recommended reducing. It noted that separating the effects of their different ingredients is difficult, so it does not prove that a particular energy drink ingredient independently causes fatty liver.

4. Sweetened fruit drinks and large amounts of fruit juice

Fruit drinks, punches and juice cocktails may contain added sugar, even when their packaging highlights fruit. Drinking them often can add calories without making it obvious how much sugar you are consuming.

Limit sweetened fruit drinks and compare labels for added sugars and serving sizes. 100% fruit juice is different: it contains naturally occurring fruit sugar and does not necessarily contain added sugar, but it can still provide considerable sugar and calories, so portion size matters. Whole fruit provides fiber and is generally a more filling choice.

The supplied reviews raise concerns about high sugar intake but do not establish that a particular amount of 100% fruit juice worsens fatty liver. The advice to limit large amounts is therefore cautious, not a claim that juice and sweetened fruit drinks have identical effects.

5. Sweetened sports drinks

Sports drinks are designed for situations where fluid and electrolyte replacement may be needed, but many also contain added sugar. When used as an everyday beverage, their sugar and calories can add up without providing a clear benefit for fatty liver.

Limit sweetened sports drinks unless a clinician has advised a particular product for a medical or activity-related need. Read the nutrition label, since formulations vary and some products contain little or no sugar.

The studies we found do not include a trial testing sports drinks in people with fatty liver. The concern is based on their possible added sugar and calorie content, rather than proof that every sports drink has the same effect on the liver.

6. Sweetened coffee and tea drinks

Coffee and tea can become high-sugar drinks when prepared with sweetened syrups, flavored powders or large amounts of sugar. Bottled versions may also contain added sugar that is easy to overlook.

Limit heavily sweetened versions and check the added sugars on packaged drinks. For drinks made to order, ask what sweeteners are included and request less or none if you prefer. The relevant issue here is the added sugar, not a claim that plain coffee or tea causes fatty liver.

The supplied reviews do not provide a direct comparison of sweetened coffee or tea with other drinks in adults with fatty liver. Their discussion of sugary beverages supports reducing added sugar, but it does not establish a benefit from changing these drinks alone.

7. Sweetened smoothies and milkshakes

Smoothies and milkshakes vary widely. Those made with sweetened ingredients, syrups or added sugar can contribute substantial calories, particularly when the serving is large or the drink is consumed alongside a meal.

Check the ingredient list and nutrition information when available, and limit versions with substantial added sugar. A fruit-based smoothie is not identical to a milkshake or a sweetened fruit drink; its ingredients and portion size matter more than its name.

The studies we found do not directly test these drinks as treatments or causes of fatty liver. Limiting highly sweetened versions follows the broader concern about excess sugar and calories, not evidence that every smoothie or milkshake must be avoided.

What should you look for when limiting drinks?

Start with the drinks you have most often. Replacing a frequently consumed sugary drink may be more practical than focusing on an occasional one, and water is a straightforward alternative. A drink does not need a detox label to be useful: the liver and kidneys do most of the body's detoxification, while the lungs and gut also help eliminate waste.

Read the nutrition label and ingredient list together. Compare added sugars in grams per serving, then check how many servings are in the container. A fruit picture, an organic label or a claim that a product is natural does not tell you whether it contains added sugar.

A 2019 review of sweeteners and pediatric fatty liver disease recommended counseling to avoid sugar-sweetened beverages but also highlighted gaps in knowledge about noncaloric sweeteners. Sugar-free labels can help identify drinks without added sugar; they do not mean a product treats fatty liver.

Who should be careful, and when should you see a doctor?

If you have fatty liver, ask a clinician about assessing its cause and the possibility of liver scarring. People with cirrhosis, diabetes or other health conditions may need an individualized plan; do not stop or change prescribed medication because of a drink choice. If you are pregnant or planning pregnancy, avoid alcohol and discuss dietary changes with your pregnancy care clinician.

Children with suspected or diagnosed fatty liver should be assessed by their pediatric clinician rather than placed on a restrictive diet without guidance. Anyone who drinks heavily or daily should ask for medical help before stopping alcohol abruptly, particularly if they have had withdrawal symptoms before.

Seek emergency care for vomiting blood, black tarry stools, severe confusion or seizures. Get urgent medical assessment for new yellowing of the eyes or skin. These signs can have several causes and should not be managed by changing drinks at home.
