Cervical Health

A healthful diet, rich in a variety of vegetables and fruits, is important for cervical health and maintaining a healthy immune system. Cruciferous vegetables, such as broccoli, cabbage, and cauliflower, may be especially beneficial.1 Cooked tomatoes, rich in the potent antioxidant lycopene, are also thought to be helpful.2

Recent studies have shown that higher intake of certain vitamins and antioxidants may reduce the risk of cervical dysplasia or cervical cancer. Specifically, increased consumption of folic acid, riboflavin, thiamin, and vitamins C, E, beta-carotene, and B12 from both food and supplements, may help decrease the risk of cervical dysplasia.3,4

A recent combined analysis of several studies reported that higher intakes or blood levels of beta-carotene, folate, lycopene, and vitamins C, E, and B12 were linked to a lower risk of cervical dysplasia. In women with proven HPV infection, lycopene and vitamins C, E, and B12 were associated with decreased risk of developing dysplasia.5

Several other studies link diets low in B vitamins, especially vitamin B12 and folate, with increased risk for cervical abnormalities.6-8 It is important to take a daily multivitamin supplement with these nutrients, along with eating a healthful diet rich in vegetables, fruits, whole grains, and low-fat meats and dairy.

Green tea polyphenols
Green tea contains disease-fighting antioxidants called catechin polyphenols (EGCG and others), which may play a role in the prevention of certain cancers. The levels of these polyphenols are higher in green tea than black tea, and instant iced tea contains only negligible amounts. Bottled teas have fewer polyphenols than freshly brewed teas.

Emerging research suggests that green tea extracts that are rich in EGCG may have a protective effect on the cervix. In a study of 90 women with preexisting cervical dysplasia, 69% of women taking green tea saw their cervical abnormalities improve, compared with only 10% of the women who did not. Researchers concluded that green tea extract was effective in improving cervical dysplasia.9

Indole-3-carbinol (I3C)
I3C is a nutrient found in cruciferous vegetables (broccoli, cabbage, cauliflower, Brussels sprouts, collard greens, and kale). I3C has been studied for its potential role in cancer prevention. Results of clinical trials in humans suggest that I3C supplementation may help treat cervical dysplasia. In one study, 50% of women taking 200 mg of I3C had complete regression of their cervical lesions after 12 weeks compared with none of the women taking a placebo supplement.10
