- Drinking coffee is linked with a lower risk of liver scarring: each extra 2 cups a day was tied to about 44% lower risk of cirrhosis.
- Alcohol and metabolic fatty liver add up. Drinking 140–350 g a week (women) or 210–420 g (men) with MASLD is now called MetALD.
- Guidelines advise people with MASLD to keep alcohol to a minimum or avoid it, and to stop completely if there is advanced scarring.
- Plain tea is a fine choice; energy drinks and green tea extract supplements call for caution.
Few questions come up more often after a fatty liver diagnosis than “Can I still have my coffee?” and “What about a drink at the weekend?” The answers are, happily, yes to the first and “less is better” for the second. This article looks at what the research says about coffee, alcohol, tea and energy drinks for people with metabolic dysfunction-associated steatotic liver disease (MASLD). For the basics of the condition, see Fatty Liver (MASLD) Explained.
Coffee: a surprising friend to the liver
Many studies have found that people who drink coffee regularly are less likely to develop liver scarring (fibrosis), cirrhosis and liver cancer. A 2016 meta-analysis pooled nine studies with more than 430,000 people.
Kennedy et al., Aliment Pharmacol Ther 2016 (5 cohort and 4 case-control studies, 432,133 participants). These are observational links, not proof that coffee causes the benefit.
Researchers think compounds in coffee, including caffeine and plant polyphenols such as chlorogenic acids, may calm inflammation and slow the build-up of scar tissue. Because the evidence is observational, doctors do not prescribe coffee as a treatment. But if you enjoy it, there is no need to give it up.
- Filter coffee, instant coffee and South Indian filter coffee all count.
- Keep sugar low; heavily sweetened coffee drinks add fructose your liver does not need. See Sugar, Fructose and Fatty Liver.
- Most healthy adults can have up to about 3–4 cups a day. Cut back if coffee affects your sleep, heart rhythm or stomach.
- Pregnant women should keep caffeine lower; ask your doctor or midwife.
Alcohol and fatty liver: the new names
In 2023, international liver societies agreed new names for fatty liver disease. MASLD describes fatty liver linked with metabolic risk factors such as a large waist, high blood sugar, high blood pressure or abnormal cholesterol. When someone has MASLD and also drinks a moderate-to-high amount of alcohol, the new category is MetALD. Above that range, alcohol is considered the main driver.
Weekly alcohol and how liver disease is labeled (grams of pure alcohol)
Rinella et al., J Hepatol 2023 (multisociety nomenclature). In daily terms, MetALD is about 20–50 g a day for women and 30–60 g a day for men.
Why does alcohol matter so much when the liver is already fatty? The liver is the main organ that breaks down alcohol. Along the way it produces toxic byproducts, makes more fat and slows the burning of fat it already holds. In a liver that is already stressed by insulin resistance and excess fat, this extra load can tip the balance toward inflammation and scarring. Alcohol also adds calories, raises triglycerides and blood pressure, and can loosen your resolve around food.
These cut-offs are labels for doctors, not safe limits. The key message is that alcohol and metabolic risk factors add to each other. Fat, inflammation and scarring can progress faster when both are present. That is why the AASLD 2023 guidance and the EASL-EASD-EASO 2024 guideline advise people with MASLD to cut alcohol to a minimum or avoid it, and to stop drinking completely if there is significant scarring or cirrhosis.
How much is a standard drink?
Countries define a “standard drink” differently. In the US it contains 14 g of pure alcohol; a UK unit is 8 g; many other countries, including those following WHO guidance, use 10 g. India has no single official standard, and home pours of spirits are often larger than a bar peg.
| Drink | Typical serving | Pure alcohol |
|---|---|---|
| Regular beer (5%) | 330 ml bottle or can | about 13 g |
| Strong beer (8%) | 650 ml bottle | about 41 g |
| Wine (12%) | 150 ml glass | about 14 g |
| Whisky, rum, vodka (40%) | 30 ml small peg | about 9 g |
| Whisky, rum, vodka (40%) | 60 ml large peg | about 19 g |
Grams of alcohol = volume in ml × strength (%) × 0.789 ÷ 100. NIAAA, What is a standard drink?
So two large pegs of whisky a night adds up to more than 260 g a week, well into the MetALD range for men. Even for the general population, a large study of about 600,000 drinkers found the lowest risk of death at around 100 g a week or less.
Tea and energy drinks
Black and green tea are fine choices. Evidence for a liver benefit is weaker than for coffee. Go easy on sugar and full-cream milk in chai.
Concentrated extracts, often sold for weight loss, have been linked with liver injury. Drinking the tea is different from taking high-dose capsules.
Often high in sugar and caffeine, and sometimes mixed with alcohol. Best avoided or kept occasional; choose sugar-free if you have one.

Get medical advice before stopping if you drink heavily every day, as sudden withdrawal can be dangerous. See a doctor urgently if you notice yellow eyes or skin, a swollen belly, vomiting blood or black stools, or confusion. Also ask before combining alcohol with medicines such as paracetamol taken regularly.
MythA little red wine is good for a fatty liver.
FactNo guideline recommends starting to drink for liver or heart health. With MASLD, the safest amount of alcohol is as little as possible.
Common questions
Does decaf coffee help too?
Some studies suggest decaffeinated coffee is also linked with lower liver risk, but the evidence is thinner. If caffeine bothers you, decaf is a reasonable choice.
Is it safe to drink occasionally with MASLD?
For people without significant scarring, guidelines advise keeping alcohol to a minimum. Your doctor can tell you whether your liver tests or scans mean you should avoid it entirely. See Fatty Liver Tests and FIB-4.
Can coffee cancel out the harm from alcohol?
No. Coffee drinkers who drink heavily still face high liver risk. Coffee is not a license to drink more.
- Regular coffee is linked with lower risk of liver scarring and cirrhosis; keep it low in sugar.
- MASLD plus 140–350 g of alcohol a week (women) or 210–420 g (men) is called MetALD.
- With MASLD, keep alcohol to a minimum or avoid it; stop completely with significant scarring.
- Know your drink sizes: a large peg of spirits holds about 19 g of alcohol.
