Are Potatoes Bad for Fatty Liver Disease 2024

Fatty liver disease affects nearly 30% of people globally. With its prevalence on the rise, many wonder, if diet changes like limiting potato intake, can help improve fatty liver. This article will explore the link between potatoes and fatty liver disease and provide diet tips for managing this condition.

How Fatty Liver Disease Develops

Fatty liver disease, also called hepatic steatosis, occurs when too much fat builds up in the liver cells. Normally, the liver contains some fat. But when fat accounts for more than 5-10% of the liver’s weight, it gets diagnosed as fatty liver.

The most common causes include:

  • Excess alcohol consumption– Drinking heavily for many years can lead to alcoholic fatty liver disease. This damages liver cells and promotes fat deposition.
  • Obesity– Being overweight or obese increases the risk of developing nonalcoholic fatty liver disease (NAFLD). Insulin resistance promotes fat accumulation in the liver.
  • Poor diet– Eating lots of processed foods high in sugar and refined carbs is linked to NAFLD. The Western diet full of red and processed meats, fried foods, and sugary items contributes to obesity and liver fat buildup.
  • Metabolic syndrome– High blood pressure, blood sugar, and triglycerides as seen in metabolic syndrome increase NAFLD risk.

If left unchecked, fatty liver can progress to liver inflammation (steatohepatitis), scarring (fibrosis), and eventually permanent liver damage.

Are Potatoes Good or Bad for Fatty Liver?

Potatoes are starchy, high-carb vegetables. But are they harmful or helpful for fatty liver disease?

Some aspects of potato nutrition seem beneficial:

  • Potatoes contain antioxidants like flavonoids, carotenoids, and vitamin C. These can help reduce liver inflammation.
  • They provide vitamin B6, niacin, and folate. B vitamins help metabolize and break down fats.
  • Potatoes have potassium, a mineral that helps manage blood pressure. High blood pressure is linked to fatty liver risk.

However, potatoes have some downsides:

  • They are high in carbohydrates with a medium-to-high glycemic index. This can increase blood sugar and insulin, promoting fat storage.
  • The carbs in potatoes can contribute to weight gain and obesity, both fatty liver risk factors.
  • Potatoes contain acrylamide, a chemical compound generated when potatoes are fried, roasted, or baked at high temperatures. Acrylamide is a potential carcinogen and neurotoxin.
  • Fried potato dishes add extra fat and calories that can overload the liver.

Overall, potatoes eaten in moderation as part of a healthy diet are unlikely to directly harm your liver. However relying too heavily on potatoes, especially fried potatoes, could promote liver fat deposition indirectly through weight gain and other mechanisms.

Why are potatoes good when the liver is fatty?

Despite their high carb content, potatoes do have some redeeming qualities that make them a better choice compared to other high-glycemic foods when you have fatty liver disease:

  1. Nutrient density – Potatoes with the skin on provide lots of vitamins, minerals, and antioxidants. Per calorie, they are more nutritious than refined grains like white rice or bread.
  2. Fiber – The fiber in potato skins helps slow digestion, preventing blood sugar spikes. Fiber also promotes satiety and weight management.
  3. Low in fat – Potatoes themselves contain little fat, especially when not fried in oil. Choosing baked, boiled, or roasted potatoes avoids adding unnecessary fats.
  4. Aid digestion – Potatoes contain carbohydrates that help promote a healthy gut microbiome. The fiber in potatoes also aids digestion and bowel regularity.
  5. Lower glycemic index – Potatoes have a moderate glycemic index of around 70 when boiled or baked. Higher GI foods like rice noodles (up to 150) would spike blood sugar more sharply.
  6. Versatile – Potatoes can be prepared in many ways – baked, mashed, roasted, sautéed, etc. This allows modifying recipes to be healthier for the liver by using less fat, salt, and sugar.

So while they should be enjoyed in moderation, the nutrients, fiber, and glycemic profile of potatoes can make them a better choice than other high-carb options when you have fatty liver disease. The key is avoiding heavy frying or high-fat toppings.

Tips for Managing Fatty Liver Disease

If you have been diagnosed with fatty liver, focus on making diet and lifestyle changes to help reduce liver fat and prevent progression to more advanced disease. Here are some tips:

  1. Lose weight – Losing even 5-10% of body weight can significantly improve fatty liver if you are overweight. Reduce calories slightly and slowly to promote safe, sustainable weight loss.
  2. Reduce high-glycemic carbs – Limit sugar, sweets, refined grains, and starchy foods like rice, pasta, and potatoes. Focus on low-glycemic whole foods instead like vegetables, legumes, nuts, and seeds.
  3. Increase fiber – Aim for 25-30g of fiber daily from fruits, vegetables, whole grains, legumes, etc. The fiber helps regulate blood sugar and cholesterol.
  4. Choose healthier fats – Swap out saturated fats from red meat and butter for monounsaturated fats in olive oil, avocados, and nuts. Omega-3s from fish and plants are also beneficial.
  5. Exercise more – Get at least 150 minutes of moderate exercise per week to improve insulin sensitivity and help lose weight through calorie burn. Try brisk walking, cycling, and swimming.
  6. Reduce alcohol – Avoid drinking alcohol altogether if you have alcoholic fatty liver disease. Limit to 1 drink per day maximum if you have NAFLD.
  7. Manage metabolic diseases – Get high blood pressure, diabetes, and high cholesterol under control through medication and lifestyle changes. This helps lower secondary risk factors for fatty liver.
  8. Try liver-friendly supplements – Ask your doctor about supplements shown to help fatty liver such as vitamin E, milk thistle, curcumin, probiotics, and omega-3s.

Making dietary changes like limiting potatoes and reducing high-glycemic carbs can help provide symptom relief and stop fatty liver from getting worse. But overall, focus on achieving long-term improvements through sustainable healthy eating, regular exercise, and weight management.

Common Questions about Potatoes and Fatty Liver Disease

Are white potatoes bad for fatty liver?

White potatoes are high glycemic and can contribute to fatty liver indirectly by promoting weight gain and insulin resistance. Enjoy potatoes in moderation, avoid frying, and always eat the skins to get fiber, nutrients, and slower carb absorption. Sweet potatoes have a lower glycemic index and more nutrients like vitamin A, so they are a healthier choice.

What kind of potatoes are worst for fatty liver?

French fries, tater tots, hash browns, potato chips, and other fried potato products are worst for fatty liver. The high heat creates acrylamide, and frying adds a lot of unhealthy fats. Mashed potatoes made with butter and whole milk are also high in saturated fat. Stick to baked, roasted, or boiled potatoes for the healthiest options.

Can you reverse fatty liver by avoiding potatoes?

Avoiding potatoes alone won’t reverse fatty liver. You need a comprehensive diet and lifestyle change to lose weight, improve insulin resistance, increase activity, avoid alcohol, and follow an overall liver-healthy eating plan. Limit potatoes and other refined carbs, but be sure to get enough calories from healthy fats, lean protein, fruits, and vegetables each day.

What happens if I eat potatoes every day with fatty liver?

Eating potatoes daily could contribute to weight gain, higher triglycerides, and insulin resistance – all of which promote fat deposition in the liver. The fiber, antioxidants, and potassium may provide some benefits, but the carb and calorie load could outweigh that. Enjoy potatoes in moderation as part of an overall healthy diet for best results.

Are sweet potatoes good for fatty liver?

Sweet potatoes are nutrient-dense and have a lower glycemic index than white potatoes. Enjoying them baked, roasted, or mashed with minimal added fat is a healthier choice compared to white potatoes when you have fatty liver disease. But still limit portion sizes, as overeating any concentrated carb can contribute to high blood sugar.

Should I avoid potato chips and French fries?

Yes, potato chips and French fries are very unhealthy with fatty liver disease. They are high in fat from frying, provide empty carbs with no nutrition, and often contain unhealthy additives. The starch, fat, salt, and preservatives are a perfect storm for encouraging inflammation, insulin resistance, obesity, and liver damage.

What potatoes are the lowest in carbs?

Small, new potatoes have slightly fewer carbs than large mature potatoes – but all varieties still have a high carb content. Per half cup cooked, red potatoes have the lowest carbs at 15g compared to 17g in new potatoes and 19g in russet. Sweet potatoes also rate lower with 17g carbs per half cup. But focus more on portion control than finding “low-carb” potatoes.


While not as detrimental as sugary foods or refined carbs, potatoes do contain a high amount of starch that can contribute to fatty liver disease progression. Enjoy potatoes in moderation as part of an overall healthy, liver-friendly diet. Limit portion sizes to 1/2 – 1 cup per meal and avoid fried preparations. Choose nutritious sweet potatoes or small red new potatoes when possible, and always eat the skins for fiber, antioxidants, and slower digestion. Focus more on increasing fiber, reducing processed carbs, managing your weight, and following an anti-inflammatory diet and lifestyle to control fatty liver disease.
