Response: Higher body mass index and alcohol intake have been shown to increase the risk of liver disease. Some studies have looked at their combined effect by comparing the risk of liver disease between individuals with both high BMI and high alcohol intake and individuals with low BMI and low alcohol intake. However, these studies have produced mixed results. Some possible reasons for that are errors in self-reported BMI and alcohol intake, other factors confounding the association of BMI & alcohol intake with liver disease risk and changes in lifestyle that individuals with ill health may have been advised to adopt.

One way to overcome these limitations is to use a technique called Mendelian randomisation. This method uses genetic differences between individuals that influence their characteristics (e.g. their body mass and how much alcohol they drink) to help understand whether these characteristics are causally related to diseases.

Our study used this method to explore the joint effects of BMI and alcohol consumption on liver disease and biomarkers of liver injury.  Continue reading

Medical Research: What is the background for this study?

Response: Our laboratory has been interested for quite some time in the relationship that natural, plant-derived compounds have on various tissues in the body. Both bone and adipocytes are derived from the same progenitor cell, mesenchymal stem cells. Thus, if a drug or compound affects one type of cell, it may affect both. When women transition through menopause, and see a reduction in their female sex hormones like estrogen, they can see adverse changes in both how much fat they store and their bone density. Thus our lab is interested in compounds that can be used to prevent the bone loss and visceral adipogenesis that menopausal women often experience. Previous work both in vivo and in vitro has shown that phytochemicals have synergistic effects and thus can ultimately work together to reduce the dosages needed to promote overall health. Through this work we have identified a combination of genistein, resveratrol, quercetin and Vitamin D that improve bone density in addition to promoting apoptosis of adipocytes. However, the health of the liver had never been addressed with our phytochemical blend. We know that supplements are sometimes toxic to the liver for many different reasons. Thus, it was very important for us to address the toxicity and potential risk of non-alcoholic fatty liver disease with our phytochemical blend in a menopausal rat model.
