Fatty liver disease, also known as NAFLD, is a condition where fat builds up in the liver. Some studies have suggested that eating nuts might help lower the risk of developing NAFLD.

In this review, the team collected information from different studies to find out if there is a link between nut consumption and NAFLD.

What is NAFLD?

NAFLD is a liver condition where too much fat accumulates in the liver cells. This can happen when a person’s diet includes a lot of unhealthy foods or when they don’t exercise enough.

NAFLD can lead to serious health problems, so finding ways to prevent it is important.

Finding the Right Studies

To learn if eating nuts can help prevent NAFLD, the team looked at different scientific studies. They searched for articles published in scientific databases like PubMed and Web of Science up until April 2023.

They selected studies that examined the relationship between nut consumption and NAFLD.

Results of the Studies

The team found a total of 11 studies that met our criteria. These studies included different types of research, such as prospective cohort studies, cross-sectional studies, and case-control studies.

They looked at how eating nuts might affect the risk of developing NAFLD.

The Relationship Between Nuts and NAFLD

When the team analyzed the data from these studies, they found that there was a significant relationship between eating nuts and a lower risk of NAFLD.

The studies showed that people who ate more nuts had a lower chance of developing NAFLD compared to those who ate fewer nuts.

The Importance of Subgroup Analysis

The team also looked at the data based on different groups of people. In subgroup analysis, they found that the protective effect of nuts on NAFLD was more significant in females.

This means that females who ate more nuts had an even lower risk of developing NAFLD compared to males.

What Does This Mean?

Based on the evidence we reviewed, it seems that including nuts in your diet may help reduce the risk of NAFLD.

Nuts contain healthy fats and other beneficial nutrients that could have a protective effect on the liver.

However, it’s important to remember that this is just one piece of the puzzle. Other factors like overall diet and physical activity also play a role in preventing NAFLD.

Further Research

While these findings are promising, more research is needed to fully understand the relationship between nuts and NAFLD.

Scientists can conduct studies to explore the effects of different types of nuts, portion sizes, and combinations with other healthy foods.

By studying these factors, we can learn more about how to prevent NAFLD and promote liver health.


The studies the team reviewed suggest that eating nuts may help lower the risk of developing NAFLD. Nuts can be a healthy addition to your diet, but they should be consumed as part of an overall balanced and nutritious eating plan.

Remember to always consult with a healthcare professional or a dietitian before making any major changes to your diet.

By making healthy choices and maintaining an active lifestyle, you can take steps to keep your liver and your body healthy.
