Mixed carotenoids include nutrients such as beta-carotene, lutein, lycopene, and others. Found in many fruits and vegetables, these nutrients are potent anti-oxidants; they protect DNA from oxidative damage which may lead to potentially cancer-causing mutations (Davidson, 1992).
A deficiency in carotenoids in the body can play a role in development of cervical dysplasia and HPV (Palan, 1992). Having higher levels is correlated with having a lower risk of HPV (Nagata, 1999).
A study of 235 women done in 2006 (Palan, 1996), compared healthy women to those with cervical cancer. It was found that women with cervical cancer had much lower levels of carotenoids in their blood. Carotenoids appear to be protective against HPV.
Making sure that you get an adequate amount of mixed carotenoids is very important to help prevent cervical dysplasia. It is also important to ensure that carotenoids are mixed (a variety of different carotenoids together), since taking a high dose of an individual carotene, especially beta carotene, may have negative effects (Cancer Prevention Study Group).
