Your liver does a great deal for your body. It gets rid of many substances that could be bad for you and makes new proteins, fats, sugars, and digestive enzymes, among other important jobs. In other words, you’re in big trouble if something hurts your liver and it can’t do its job.
Fatty liver disease, also known as nonalcoholic fatty liver disease (NAFLD), affects nearly 25% of people globally It involves fat accumulation in liver cells, which can progress to inflammation, scarring, and serious liver damage if left untreated. Making dietary and lifestyle changes is key to managing this condition. But can something as simple as canned tuna provide benefits? Let’s find out
An Overview of Fatty Liver Disease
Fatty liver occurs when too much fat builds up in the liver. There are two main types
- Non-alcoholic fatty liver (NAFL) – fat in the liver with little or no inflammation/damage
- Nonalcoholic steatohepatitis (NASH) – liver inflammation and damage along with excess fat
Often there are no symptoms, but they may include:
- Fatigue
- Abdominal discomfort
- Enlarged liver
- Yellowing skin and eyes
Without intervention, NASH can lead to cirrhosis, liver failure, and liver cancer. Risk factors include obesity, diabetes, high cholesterol, and metabolic syndrome.
Doctors recommend weight loss through diet and exercise as first-line treatment. But what foods can also help reverse fatty liver?
The Role of Omega-3s for Fatty Liver
Omega-3 fatty acids have emerged as a key nutrient for managing NAFLD. Studies show getting enough omega-3s from fish and fish oil can:
- Lower liver fat and inflammation
- Reduce fibrosis and progression to NASH/cirrhosis
- Improve fat metabolism and insulin sensitivity
- Enhance cardiovascular health
The anti-inflammatory effects and triglyceride lowering properties explain the benefits. The main omega-3s involved are:
- ALA – Found in plants like flaxseeds, chia seeds, walnuts
- EPA – Found in fatty fish and fish oil
- DHA – Found in fatty fish and fish oil
For reducing liver fat, EPA and DHA seem most effective. Experts recommend 250-500 mg daily of EPA/DHA for optimal liver health.
How Does Canned Tuna Stack Up?
Canned tuna is a convenient source of omega-3s. But how does it compare to fresh tuna in supporting liver health?
Nutrition Profile
A 3 ounce (85g) serving of canned light tuna provides:
- 20-25g protein
- 1-2g fat
- 50-80mg combined EPA/DHA
- 150-200 calories
It’s also a good source of selenium, niacin, vitamin B12, and potassium. However, it can be high in sodium. Rinsing before eating can reduce the sodium content.
Overall, canned tuna is high in protein, low in fat/calories, and delivers a moderate amount of anti-inflammatory omega-3s.
Benefits for Fatty Liver
As an omega-3 source, tuna can benefit NAFLD. The omega-3s in one 3 ounce serving provide 20-30% of the recommended daily intake. Consuming tuna 1-2 times per week helps meet omega-3 needs to lower liver fat over time. Combining tuna with other omega-3 foods like salmon, walnuts, and chia seeds optimizes these effects.
Beyond omega-3s, the high-quality protein in tuna helps maintain muscle mass when losing weight to treat NAFLD. And the B12 supports healthy fat metabolism.
Potential Downsides
A few potential downsides to note:
- Higher mercury levels than some fish – limit to 2-3 servings per week
- High sodium if not rinsed before eating
- Not as high in omega-3s as salmon or sardines
- Lacks nutrients found in fresh fish
But the convenience, nutrition profile, and low cost still make canned tuna a good choice for NAFLD – though fresh fish is ideal when possible.
Incorporating Canned Tuna into a Fatty Liver Diet
If you have fatty liver disease, here are tips for fitting canned tuna into an overall NAFLD diet and lifestyle:
- Choose tuna in water over oil
- Look for low sodium or no salt added
- Rinse to remove some sodium
- Limit to 2-3 servings weekly due to mercury
- Balance with other omega-3 foods like salmon, walnuts, chia seeds
- Eat more fruits, vegetables, whole grains, beans, healthy fats
- Reduce sugar, refined carbs, saturated fat, fried foods
- Aim for 7-10% weight loss if overweight
- Get regular exercise – cardio and strength training
- Address related conditions like diabetes and high cholesterol
- Discuss omega-3 supplements with your doctor if needed
- Get regular blood tests and imaging to monitor liver health
Focusing on a balanced, liver-friendly diet with tuna in moderation provides the best opportunity for reversing fatty liver disease. Partner with your doctor for a customized nutrition and lifestyle plan.
Other Liver-Supporting Foods
While canned tuna has some clear benefits for NAFLD, emphasize a variety of healthy foods like:
- Oily fish: Salmon and sardines contain more omega-3s than tuna
- Nuts/seeds: Walnuts, chia seeds, flaxseeds provide anti-inflammatory omega-3s
- Olive oil: Provides beneficial monounsaturated fats to lower liver fat
- Avocados: Supply monounsaturated fats and fiber
- Leafy greens: Provide vitamins, minerals, and fiber
- Berries: Contain antioxidants and polyphenols to protect the liver
- Green tea: May reduce fatty liver risk thanks to antioxidants
- Cruciferous vegetables: Support liver detox
The Bottom Line
However, fresh fish like salmon contain more omega-3s than canned tuna. And tuna has some potential downsides, including high sodium if not rinsed. Still, for an affordable, convenient source of protein and omega-3s, tuna remains a smart choice.
Focus on moderation and variety by balancing tuna with other nutritious foods. Most importantly, make the necessary lifestyle changes like weight loss, exercise, and alcohol avoidance to manage and reverse fatty liver disease.
How Are Diet And Liver Health Related?
If NAFLD isn’t caused by alcohol, then what are its causes? Are any of them dietary?
As we discussed earlier, dietary sugars—especially refined sugars, fructose, and HFCS—pose the biggest threat to your liver. 5 That’s why a high-sugar diet is so closely associated with the onset of NAFLD. 5.
This means that cutting back on sugary foods can help prevent NAFLD. Yes! Studies show that if you eat and drink less sugary things, it may stop fat from building up in your liver, which can protect you from NAFLD. 5.
How can you cut down on sugar in general? There are many ways that hidden or added sugars can get into your food. We’ve already mentioned fruit and honey. Many people disregard their sugar content because they’re natural and less processed. However, these foods are primary sources of fructose.
Another common category to watch out for is canned foods. It is important to always read food labels to find out how many grams of sugar are in 100 grams of food. e. , the percentage sugar). For instance, if a serving size is 555 grams and there are 2015 grams of sugar in each serving, then that food is 227 grams of sugar (15 divided by 55 and multiplied by 100). That’s pretty high! To protect yourself from NAFLD, you should choose foods that have less than 5% sugar.
Your Liver Needs Nutrition To Stay Healthy
Your liver needs nutrients just like all other organs in your body. Eating the right foods can support your liver in performing its functions. Certain nutrients are particularly good for liver health. But before we can figure out why these nutrients can help or protect the liver, we need to know what can go wrong with it.
