Clinical Trials on Kohlrabi
The first clinical trial on kohlrabi was conducted by researchers from the University of Padova in Italy and published in the journal Nutrients in 2016. The study found that kohlrabi may have a beneficial effect on lipid metabolism and cardiovascular health. Specifically, the researchers found that a diet containing kohlrabi significantly reduced levels of total cholesterol, LDL cholesterol, and triglycerides. They also found that kohlrabi was able to reduce the oxidation of low-density lipoprotein (LDL) cholesterol and increase levels of high-density lipoprotein (HDL) cholesterol.
Another clinical trial, this one conducted by researchers from the University of Pisa in Italy, was published in the journal BMC Complementary and Alternative Medicine in 2017. This study investigated the effects of kohlrabi on inflammation and oxidative stress. The researchers found that consuming kohlrabi significantly reduced markers of inflammation and oxidative stress, including C-reactive protein (CRP) and lipid hydroperoxide (LPO) levels.
The most recent clinical trial on kohlrabi was conducted by researchers from the University of Milan in Italy and published in the journal Phytotherapy Research in 2019. This study evaluated the effects of kohlrabi juice on metabolic and cardiovascular health in type 2 diabetic patients. The researchers found that consuming kohlrabi juice for three months significantly reduced levels of fasting glucose and HbA1c, as well as total cholesterol, LDL cholesterol, and triglycerides. They also observed a significant increase in HDL cholesterol.
