Coffee is the single most studied beverage for fatty liver, and the evidence strongly favors drinking it. But your overall drink choices matter just as much as adding one helpful option. What you stop drinking, particularly sugary beverages, may have a bigger impact than anything you add. Here’s what the research says about the best and worst drinks for a fatty liver.
Coffee: The Strongest Evidence
Coffee consistently shows protective effects against liver fat buildup and the scarring (fibrosis) that can follow. In a study of 347 people, drinking three or more cups per day was linked to less liver fibrosis. Compared to people who drank fewer than two cups daily, those who had more than three cups had a lower risk of developing fatty liver disease in the first place.
The benefits come from multiple angles. Coffee contains antioxidants that protect liver cells from damage, and a natural compound called kahweol that helps reduce liver inflammation. At a deeper level, coffee appears to quiet the cells responsible for producing scar tissue in the liver and activates your body’s built-in antioxidant defense system. These effects apply to both caffeinated and, to a lesser extent, decaffeinated coffee, since some of the protective compounds aren’t caffeine itself.
Three cups a day is the threshold most studies point to, though researchers note that the exact “dose” still needs confirmation in larger trials. Black coffee or coffee with minimal added sugar is the goal. Loading it with flavored syrups or whipped cream works against you.
Water: Simple but Effective
Plain water doesn’t contain any magic ingredient for your liver, but higher water intake is independently linked to lower rates of newly diagnosed fatty liver disease, at least in men. The mechanism is indirect but meaningful: drinking more water tends to lower total calorie intake, reduce body weight, and increase fat burning. Since excess body fat is the primary driver of fatty liver, those effects add up. If you’re currently drinking juice, soda, or sweetened tea throughout the day, swapping those for water removes a source of liver-damaging sugar while keeping you hydrated.
Green Tea
Green tea contains catechins, a group of antioxidants that have shown liver-protective properties in lab and animal studies. The most studied of these is EGCG, which appears to reduce fat accumulation in liver cells and lower markers of inflammation. Clinical evidence in humans is less robust than for coffee, but green tea is a reasonable addition to your routine. Stick to brewed tea rather than concentrated green tea extract supplements, which have been linked to liver injury at high doses.
Beetroot Juice: A Promising Option
Beetroot juice has gained attention for fatty liver specifically. It’s rich in dietary nitrates, which your body converts into nitric oxide, a molecule that reduces liver inflammation and improves blood flow. Beetroot also contains betaine and antioxidants that help the liver process and eliminate fat.
In a clinical trial comparing beetroot juice to a Mediterranean diet in people with fatty liver disease, both groups saw reduced liver fat on ultrasound. The beetroot juice group actually showed a more significant reduction in liver fat than the diet-only group. The combination of beetroot juice plus a Mediterranean diet performed best of all. This is one of the few beverages beyond coffee with direct trial evidence showing measurable improvement in liver fat.
Low-Fat Dairy and Plant Milks
Not all dairy affects your liver the same way. In a large cohort study, people who consumed higher amounts of low-fat, low-sugar dairy products had 58% lower odds of developing or retaining fatty liver disease compared to those who consumed less. High-fat dairy, on the other hand, was associated with greater odds of fatty liver onset or persistence. If you drink milk, choosing skim or low-fat versions appears to be the better option. Neither low-fat nor high-fat dairy was linked to worsening fibrosis, so the concern is specifically about fat accumulation in the liver rather than scarring.
Animal studies comparing milk fat to soybean oil found similar weight gain and liver fat with both types of high-fat diets, so plant-based milks aren’t automatically better. The key variable is total fat content, not the source. Unsweetened almond, oat, or soy milk are all reasonable choices as long as you check the label for added sugars.
Herbal Teas With Liver-Supporting Ingredients
A randomized, placebo-controlled trial tested a liquid formula containing extracts of turmeric, dandelion, milk thistle, and ginger taken twice daily for six months. Participants showed significantly greater improvements in all four major liver enzymes compared to placebo. These are commonly available as individual herbal teas, and while the trial used a concentrated formula rather than a casual cup of tea, the results suggest these herbs have real effects on liver function markers. Milk thistle and turmeric teas are widely available and safe for most people at normal dietary amounts.
What to Stop Drinking
Sugary Beverages
Sugar-sweetened drinks are one of the most direct contributors to fatty liver. Fructose, the primary sugar in soda, fruit punch, and many sweetened teas, is processed almost entirely by the liver. When you consume it in liquid form, it arrives quickly and in high concentrations, triggering your liver to convert it directly into fat through a process called de novo lipogenesis.
In one study, drinking fructose-sweetened beverages that provided 25% of daily calories for 10 weeks significantly increased both liver fat production and visceral belly fat. Another trial found that drinking about three small sugar-sweetened sodas per day (roughly 80 grams of sugar) for just six weeks was enough to ramp up the liver’s fat-making machinery. On the flip side, when children with obesity who normally consumed more than 50 grams of fructose daily had their fructose intake restricted, their liver fat production dropped measurably. Cutting sugary drinks is one of the highest-impact changes you can make.
Diet Soda
Diet soda gets a neutral verdict. A six-year study from the Framingham Heart Study found no association between diet soda consumption and liver fat or new fatty liver diagnoses. Increasing or decreasing diet soda intake didn’t change the odds either way. Artificial sweeteners like sucralose and aspartame don’t appear to raise blood sugar or trigger the same metabolic cascade as real sugar. One animal study even suggested that rebaudioside, a stevia-derived sweetener, may have mild liver-protective effects. Diet soda isn’t beneficial, but if it helps you stop drinking regular soda, the trade is worth it.
Alcohol
If you already have fatty liver, alcohol accelerates damage. European clinical guidelines for fatty liver management explicitly recommend discouraging alcohol consumption alongside dietary changes and weight loss. Even low-to-moderate drinking (as few as 5 to 9 drinks per week) is associated with increased liver fibrosis in people who already have metabolic fatty liver disease. There is no safe threshold that has been established for people with existing liver fat. The cleanest approach is to avoid alcohol entirely while working to reverse the condition.
Putting It All Together
Your daily drink lineup for fatty liver should center on coffee (up to three or more cups, ideally black or lightly sweetened), plenty of water, and green or herbal tea. Beetroot juice a few times a week adds a proven liver-fat-reducing boost. Low-fat milk is fine; high-fat dairy drinks are not ideal. The single most important change for many people will be eliminating sugary drinks entirely, since liquid fructose is one of the fastest routes to increased liver fat. Alcohol should be minimized or, better yet, avoided altogether if you already have a fatty liver diagnosis.
