BETA-CAROTENE FOODS PROTECT BEST AGAINST OVARIAN CANCER
A study published in The American Journal of Epidemiology (September 1989, pp. 497-502) reports that high dietary intake of beta-carotene conferred greater protection against ovarian cancer development than did vitamins A,C, or fiber in a population-based, case-control study of 85 primary ovarian cancer cases and 492 controls, after adjustment for age, number of pregnancies and body mass index. Cases (20-79year old residents of Salt Lake, Davis, Weber or Utah counties diagnosed between May 31,1987 and August 1, 1989 (with tissue-exam-confirmed ovarian cancer) were identified within six weeks of diagnosis. Controls (those with no identified cancer) age 20 or older were identified through random digit-dialing and Health Care Finance Administration records.
