Are Beans Good for Fatty Liver? Fiber, Protein and Canned Beans

TL;DR

• Beans are a good food for fatty liver: high in fiber and plant protein, with almost no saturated fat, and a staple of the Mediterranean-style diet liver guidelines recommend.
• Research on beans alone is limited, but a large UK study linked swapping red and processed meat for legumes to a slightly lower rate of fatty liver.
• Watch the sodium in canned beans and the sugar in baked beans, and add beans gradually if they give you gas.

Yes, beans are good for fatty liver. Black, kidney, pinto and navy beans are rich in fiber and plant protein, contain almost no saturated fat, and are part of the Mediterranean-style diet recommended for MASLD (formerly NAFLD).

The research on beans by themselves is limited, so their biggest benefit is as a swap: a bowl of beans in place of processed or fatty red meat. Sodium in canned beans and gas are the two practical hurdles, and both are easy to manage.

Why are beans good for a fatty liver diet?

Beans line up with nearly everything liver guidelines ask for:

• Fiber. The AASLD’s 2023 guidance encourages diets “enriched with high fiber and unsaturated fats (eg, Mediterranean diet).” Half a cup of cooked beans has about 6 to 10 g of fiber, a fifth to a third of the 28 g Daily Value.
• Plant protein with almost no saturated fat. Half a cup has about 7.5 g of protein and roughly 0.1 g of saturated fat, which makes beans an easy way to cut back on fatty meat.
• A Mediterranean staple. The 2024 European guideline describes the Mediterranean diet as high in “olive oil, vegetables, fruits, nuts and seeds, legumes, whole grains, fish, and seafood,” and lists legumes among the minimally processed foods to build meals around.
• Filling for few calories. Weight loss is the main treatment for fatty liver. Guidelines aim for at least 5% of body weight to reduce liver fat, 7 to 10% to improve inflammation and 10% or more to improve fibrosis, and fiber-rich, protein-rich foods help you eat less without feeling deprived.

How do beans compare? Nutrition per ½ cup

Here’s what half a cup of beans cooked from dried, without salt, provides:

Per ½ cup cooked	Calories	Protein	Fiber	Carbs	Potassium
Black beans	114	7.6 g	7.5 g	20.4 g	305 mg
Kidney beans	112	7.7 g	5.7 g	20.2 g	358 mg
Pinto beans	122	7.7 g	7.7 g	22.4 g	373 mg
Navy beans	127	7.5 g	9.6 g	23.7 g	354 mg

Source: USDA FoodData Central (SR Legacy).

All four are close. Navy beans lead on fiber, and all have about 0.1 g of saturated fat and almost no sodium when cooked from dried without salt. Beans do contain carbohydrate, so if you have diabetes, count them toward your carbs like any other starchy food. Lentils and chickpeas are legumes too, with similar fiber and protein.

What does research say about beans and fatty liver?

The evidence is observational and fairly thin, but it leans in a helpful direction:

• A 2020 meta-analysis in the British Journal of Nutrition pooled three cross-sectional studies and found no significant link between legume intake and fatty liver. The one case-control study it included found lower odds.
• That case-control study, from Tehran, compared 196 adults newly diagnosed with fatty liver with 803 people without it. Higher intake of legumes, including beans, was linked to lower odds of fatty liver.
• A UK Biobank substitution study followed 124,546 adults for a median of about 10.5 years. Replacing 80 g a week of red and processed meat with legumes was linked to a 4% lower rate of fatty liver, and replacing poultry was linked to a 3% lower rate. Swapping fish for legumes showed no link.

These are modest associations, not proof that beans treat fatty liver. The clearest takeaway is about substitution: beans are a better regular choice than the red and processed meats more consistently linked to fatty liver. Our guide to pork and fatty liver covers that side of the research.

Canned or dried beans: what about the sodium?

Canned beans are just as nutritious as dried in most ways. Salt is the main difference:

Per ½ cup	Sodium
Black beans, cooked from dried without salt	1 mg
Kidney beans, cooked from dried with salt	211 mg
Black beans, canned, low sodium	166 mg
Black beans, canned, regular	461 mg
Refried beans, canned, traditional style	440 mg
Baked beans, canned, plain or vegetarian	436 mg

Source: USDA FoodData Central (SR Legacy). Canned values include the liquid.

Ways to cut the salt:

• Buy “no salt added” or “low sodium” cans.
• Drain and rinse. In a University of Tennessee study, draining canned beans cut sodium by about 36%, and draining plus rinsing cut it by about 41%.
• Cook a big batch from dried and freeze it in 1½-cup portions, about the amount in a can.
• Season with spices, such as cumin, smoked paprika, garlic and chili, instead of salt pork or bouillon. See is salt bad for fatty liver for more on sodium.

One safety note for dried kidney beans: raw or undercooked kidney beans contain a natural toxin, and the FDA says as few as four or five raw beans can trigger symptoms, starting with extreme nausea and vomiting. Soak dried kidney beans for at least 5 hours, pour off the water and boil them in fresh water for at least 30 minutes. Don’t cook dried kidney beans from raw in a slow cooker, which may not get hot enough. Canned beans are already cooked.

How can you eat more beans without the gas?

Gas is a common reason people avoid beans, and for many people it eases with time. In three feeding studies where adults ate half a cup of beans daily for 8 to 12 weeks, fewer than half reported more gas from pinto or baked beans in the first week. By the second week of the two crossover trials, 6% reported more gas from pinto beans and 24% from baked beans. In the longer pinto bean trial, reports fell more slowly, with 15% to 23% still noticing more gas in weeks 6 to 12.

What helps:

• Start small. Begin with a quarter cup and build up over a couple of weeks.
• Soak dried beans and discard the water. Soaking removes some of the raffinose-type sugars that gut bacteria turn into gas.
• Rinse canned beans, which also lowers the sodium.
• Try different beans. People react differently to different types.
• Consider an enzyme. In a small 1994 crossover trial of 19 people, published in the Journal of Family Practice, an over-the-counter alpha-galactosidase product taken with a meatless chili meal reduced gas. Check with your pharmacist or doctor before starting any supplement.

Easy ways to eat beans with fatty liver

• Black bean tacos with salsa, cabbage and avocado instead of ground beef
• Chili made with half the usual meat and twice the beans
• White bean and tuna salad with lemon and olive oil; see is tuna good for fatty liver
• Bean and vegetable soup in place of a ham-based soup
• Burrito bowls with pinto beans, a modest scoop of brown rice and lots of vegetables; our guide to rice and fatty liver covers the grain side
• Mashed beans as a sandwich spread instead of cheese

Watch what goes on top. Cheese, sour cream, lard-based refried beans and bacon in baked beans add the saturated fat beans don’t have. If you log meals in an app like Liverly, you can see how a bean-based dinner changes your fiber and saturated fat totals compared with a meat-heavy one.

If you have cirrhosis, beans can be a useful protein source, but ask your care team about portions, the sodium in canned beans if you have ascites, and potassium if you take certain diuretics. See our cirrhosis diet guide.

The Bottom Line

Beans are good for fatty liver. They are high in fiber and plant protein, almost free of saturated fat, filling and cheap, and they are a staple of the Mediterranean-style diet liver guidelines recommend. The research on beans alone is limited, but swapping red and processed meat for legumes is linked to a slightly lower rate of fatty liver.

Aim for a half cup to a cup several times a week, choose low-sodium canned beans or cook your own, rinse canned beans, go easy on sweet baked beans and cheesy toppings, and add them gradually if gas is a problem.
