Consuming high-fat dairy products, such as whole milk, cream, frozen yoghurt, butter, and ghee, may significantly elevate the risk of developing fatty liver disease, according to a recent study.
The research, presented in the esteemed Journal of Hepatology Reports, highlighted the benefits of opting for low to medium-fat dairy alternatives, including skimmed milk, cottage cheese, and low-fat cheese, which could serve as protective options against Metabolic dysfunction-associated steatotic liver disease (MASLD).
To explore this critical issue further, a dedicated team of researchers from the Hebrew University of Jerusalem, Israel, embarked on a dual approach, conducting experimental studies involving mice alongside an observational study involving human participants.
They discovered that low-medium fat, low-sugar dairy products offer greater protection against liver disease compared to their high-fat counterparts, underscoring the potential dangers associated with high-fat dietary intake.
“It would be advisable to prefer low-fat low-sugar dairy products and minimise intake of high-fat dairy products; however, additional evidence is needed to allow generalisability of our findings,” the researchers remarked, emphasizing the need for further research in this area.
In their animal study, 6-week-old male mice were subjected to a high-fat diet (HFD) composed of lard, soybean oil, and milk fat for a duration of 12 weeks, allowing the team to closely monitor the effects of high-fat consumption.
All subjects on the high-fat diet exhibited comparable weight gain and steatosis, yet did not display any significant changes in liver enzyme levels. Interestingly, milk fat was found to elevate serum cholesterol and advanced glycation end-products (AGEs) levels to a greater extent than lard or soybean oil, raising concerns over its impact on health.
Furthermore, in a clinical study involving 316 patients, researchers observed that a high intake of low-medium fat, low-sugar dairy products correlated with a notably reduced risk of MASLD incidence, suggesting a protective dietary approach could be beneficial.
**Interview with Dr. Emily Carter, Hepatologist and Nutrition Specialist**
**Interviewer:** Thank you for joining us today, Dr. Carter. There’s new research suggesting that consuming high-fat dairy products can increase the risk of Nonalcoholic Fatty Liver Disease (NAFLD). Can you explain why this is concerning?
**Dr. Carter:** Absolutely. The study published in the Journal of Hepatology Reports underscores a significant link between high-fat dairy consumption and the development of NAFLD. The liver is essential for fat metabolism, and when excess saturated fats, commonly found in high-fat dairy products, are consumed, they can accumulate in liver cells, leading to fatty liver disease. This can progress to more severe liver conditions if not managed.
**Interviewer:** So, what are some alternatives that you would recommend for those looking to maintain liver health?
**Dr. Carter:** I advise incorporating low to medium-fat dairy options into your diet. Choices like skimmed milk, cottage cheese, and low-fat cheeses not only provide essential nutrients without the added saturated fats but also support overall metabolic health. These alternatives can be just as satisfying while minimizing the risk for NAFLD.
**Interviewer:** It sounds like making small dietary changes can have a significant impact. Are there other lifestyle modifications that can help reduce the risk of NAFLD?
**Dr. Carter:** Definitely. In addition to choosing healthier dairy options, maintaining a balanced diet rich in fruits, vegetables, whole grains, and lean proteins is key. Regular physical activity is equally important in managing weight and preventing liver fat accumulation. Limiting sugar and refined carbohydrates can also be beneficial.
**Interviewer:** Thank you, Dr. Carter. This information is vital for those looking to protect their liver health and reduce the risk of NAFLD.
**Dr. Carter:** Thank you for having me; it’s important to spread awareness about these lifestyle changes. Every small step counts towards better liver health!
