Metabolic syndrome is a combination of abnormal body functions that increase the risk of cardiovascular disease and diabetes. Typically signs such as excessive weight, higher than normal triglyceride levels, lower than normal HDL cholesterol, higher than normal blood pressure, and higher than normal fasting blood sugar are indicators of having metabolic syndrome.
A recent study, after controlling for all other factors, found that adults with metabolic syndrome consistently had lower concentrations of carotenoids from serum antioxidants than those without metabolic syndrome. Serum antioxidants that were included were retinol, retinyl esters, carotenoids(a-carotene, B-carotene, B-cryptoxanthin, lutein+zeaxanthin, total lycopene), vitamin E, and vitamin C.
While vitamin E did not show a significant relationship with metabolic syndrome, there was an inverse relationship of retinol and retinyl esters among men only. Also, vitamin C showed a similar pattern to carotenoids as it had an inverse linear association with metabolic syndrome.
The study helps to give support to the argument of using nutrition to fight metabolic syndrome, diabetes, and cardiovascular disease.
