It also induces glutathione production (21) ; enhances macrophage function and natural killer (NK) cell cytotoxicity; and increases T-helper lymphocyte counts. A randomized, placebo-controlled clinical trial of beta-carotene and retinol was conducted with 755 former asbestos workers as study subjects. The targeted endpoint for the intervention study was a reduction in the incidence and prevalence of sputum atypia. The dosage of 50 mg beta-carotene/d and 25,000 IU Later: no effect on risk of dying from gastric cancer. Alpha-Tocopherol/Beta-Carotene Cancer Background: The Beta-Carotene and Retinol Efficacy Trial (CARET) tested the effect of daily β-carotene (30 mg) and retinyl palmitate (25 000 IU) on the incidence of lung cancer, other cancers, and death in 18 314 participants who were at high risk for lung cancer because of a history of smoking or asbestos exposure.

The objective was to review the effect of beta‐carotene supplementation on cancer incidence in randomized trials by cancer site, beta‐carotene supplementation characteristics and study population. 2017-09-20 · Physicians’ Health Study. The Physicians’ Health Study randomly assigned 22,071 male physicians aged 40 to 94 living in the United States to receive beta-Carotene (50 mg every 2 days) or Among the subjects who received beta carotene, the relative risk of death from any cause was 1.08 in the ATBC Cancer Prevention Study (3570 deaths), 1.01 in the Physicians' Health Study (1947 The results are highly consistent with those found for β-carotene in the Alpha-Tocopherol Beta-Carotene Cancer Prevention Study in 29 133 male smokers in Finland. Implications : Individuals at high risk of developing lung cancer, i.e., current smokers and asbestos-exposed workers, should be discouraged from taking supplemental β-carotene (and the combination of β-carotene with vitamin A). Abstract. Background: Epidemiologic studies have suggested that vitamin E and β-carotene may each influence the development of prostate cancer.

CARET was stopped ahead of schedule in January 1996 because participants who were randomly assigned to receive the active intervention were found to have a 28% increase in The ATBC Study is uniquely positioned to investigate the relationship between mtDNA copy number and pancreatic cancer risk because of the population’s exposure to oxidative stress due to smoking, their exposure to the beta-carotene and alpha-tocopherol study intervention, and the collection of biomarkers (beta-carotene, alpha-tocopherol, and retinol measured at baseline and after the study intervention), all of which can potentially modify mtDNA copy number. Men with the lowest blood levels of beta-carotene at the start of the study who took supplements had a 32% reduction in risk of prostate cancer. Beta-carotene supplements did not affect the risk of Use of beta-carotene has been associated with an increased risk of lung cancer in people who smoke or who have been exposed to asbestos. One study of 29,000 male smokers found an 18% increase in lung cancer in the group receiving 20 mg of beta-carotene a day for 5 to 8 years. Nutrient/compound Mode of action Site of action Sources vitamin A (retinol, retinal, retinoic acid and its carotenoid precursors) The most convincing evidence that vitamin A and its precursors, the carotenoids, prevent human cancer comes from prospective and retrospective epidemiologic studies associating low intakes of fruits and vegetables The conflicting evidence of the relation between β-carotene and lung cancer in humans serves as a poignant case study with respect to what types of evidence are sufficient to support or change a nutrition recommendation.
