  • dietary Acrylamide intake and risk of premenopausal breast cancer
    American Journal of Epidemiology, 2009
    Co-Authors: Kathryn M. Wilson, Lorelei A Mucci, David J Hunter, Wendy Y Chen, Walter C. Willett
    Abstract:

    Acrylamide, a probable human carcinogen, is formed during high-temperature cooking of many commonly consumed foods. It is widespread; approximately 30% of calories consumed in the United States are from foods containing Acrylamide. In animal studies, Acrylamide causes mammary tumors, but it is unknown whether the level of Acrylamide in foods affects human breast cancer risk. The authors studied the association between Acrylamide intake and breast cancer risk among 90,628 premenopausal women in the Nurses' Health Study II. They calculated Acrylamide intake from food frequency questionnaires in 1991, 1995, 1999, and 2003. From 1991 through 2005, they documented 1,179 cases of invasive breast cancer. They used Cox proportional hazards models to assess the association between Acrylamide and breast cancer risk. The multivariable-adjusted relative risk of premenopausal breast cancer was 0.92 (95% confidence interval: 0.76, 1.11) for the highest versus the lowest quintile of Acrylamide intake (Ptrend = 0.61). Results were similar regardless of smoking status or estrogen and progesterone receptor status of the tumors. The authors found no associations between intakes of foods high in Acrylamide, including French fries, coffee, cereal, potato chips, potatoes, and baked goods, and breast cancer risk. They found no evidence that Acrylamide intake, within the range of US diets, is associated with increased risk of premenopausal breast cancer.

  • Validation of a food frequency questionnaire measurement of dietary Acrylamide intake using hemoglobin adducts of Acrylamide and glycidamide
    Cancer Causes & Control, 2009
    Co-Authors: Kathryn M. Wilson, Hubert W Vesper, Margareta Törnqvist, Paula Tocco, Laura Sampson, Johan Rosén, Karl-erik Hellenäs, Walter C. Willett
    Abstract:

    Objective Acrylamide, a probable human carcinogen, is formed during high-heat cooking of many common foods. The validity of food frequency questionnaire (FFQ) measures of Acrylamide intake has not been established. We assessed the validity of Acrylamide intake calculated from an FFQ using a biomarker of Acrylamide exposure. Methods We calculated Acrylamide intake from an FFQ in the Nurses’ Health Study II. We measured hemoglobin adducts of Acrylamide and its metabolite, glycidamide, in a random sample of 342 women. Correlation and regression analyses were used to assess the relationship between Acrylamide intakes and adducts. Results The correlation between Acrylamide intake and the sum of Acrylamide and glycidamide adducts was 0.31 (95% CI: 0.20–0.41), adjusted for laboratory batch, energy intake, and age. Further adjustment for BMI, alcohol intake, and correction for random within-person measurement error in adducts gave a correlation of 0.34 (CI: 0.23–0.45). The intraclass correlation coefficient for the sum of adducts was 0.77 in blood samples collected 1–3 years apart in a subset of 45 women. Intake of several foods significantly predicted adducts in multiple regression. Conclusions Acrylamide intake and hemoglobin adducts of Acrylamide and glycidamide were moderately correlated. Within-person consistency in adducts was high over time.

  • Acrylamide in Potato Products
    Advances in Potato Chemistry and Technology, 2016
    Co-Authors: Bruno De Meulenaer, Raquel Medeiros, Frédéric Mestdagh
    Abstract:

    Abstract Acrylamide is proven to be carcinogenic in rodents and a “probable” human carcinogen, with increasing evidence of positive associations with human cancers. Thus, authorities and industry are asking for solutions for Acrylamide formation, while no legal limits have yet been established for Acrylamide in foods. Most of the Acrylamide dietary exposure results from potato products, coffee, bakery products, and chocolate. Acrylamide is formed in potato products during industrial processing, retail, catering, and home preparation. This review summarizes the research as of this writing on Acrylamide levels, mechanisms of formation, assessment of Acrylamide intake and health risk, regulatory status, and possible mitigation strategies from farm to fork in fried potato products. Furthermore, relevant issues regarding the implementation of mitigation strategies on an industrial scale are discussed and options for risk management summarized. In conclusion, “lab-scale studies” in Acrylamide mitigation research should be interpreted with utmost care. This leads to the pertinent question “What is the next step to reduce Acrylamide exposure while maintaining the expected product quality for the consumer?”

  • Assessing Human Exposure To Acrylamide
    2005
    Co-Authors: Hubert W Vesper, Tunde Meyers, Maria Ospina, Antoinette Smith, Leigha Ingham, G. Gray, Gary L. Myers
    Abstract:

    Acrylamide is considered as probably carcinogenic to humans. The International Agency for Research on Cancer (IARC) rates it as a Group 2A reagent. Therefore, human exposure to Acrylamide in occupational settings has been of concern for a long time. Until recently, tobacco smoke was assumed to be the only major source of Acrylamide exposure in the general population. Now, it is well established that Acrylamide is formed in food during processing or cooking at high temperatures. Surveys showed that Acrylamide can be found in most types of food, with highest amounts measured in French fries and potato chips. The concentrations found in some foods exceed the concentrations found for other environmental contaminants, such as pesticides. The Division of Laboratory Sciences at CDC’s National Center for Environmental Health, through a biomonitoring program project, is assessing people’s exposure to this chemical. The goal is to better assess the magnitude and distribution of human exposure to Acrylamide and risks associated with this exposure in the general population. Project researchers are measuring biomarkers of exposure such as hemoglobin adducts of Acrylamide and its primary metabolite glycidamide. First assessments show that biomarker levels mainly range between 27 pmol/g globin and 148 pmol/g globin for Acrylamide and glycidamide adducts, respectively. Biomarker values in smokers are about 3 to 4 times higher than in non-smokers. An initial study looked at the effects of Acrylamide in food on biomarkers of Acrylamide exposure. Results indicate that Acrylamide consumed through food has a more profound effect on glycidamide adduct levels than on Acrylamide adduct levels. The Acrylamide biomarker concentrations determined so far are within the range reported by other investigators. Smoking appears to be an important contributor to the background exposure found in people.

  • pilot study on the impact of potato chips consumption on biomarkers of Acrylamide exposure
    Advances in Experimental Medicine and Biology, 2005
    Co-Authors: Hubert W Vesper, Hermes Liceaperez, Tunde Meyers, Maria Ospina, Gary L. Myers
    Abstract:

    Food is assumed to be one major source of Acrylamide exposure in the general population. Acrylamide exposure is usually assessed by measuring hemoglobin adducts of Acrylamide and its primary metabolite glycidamide as biomarkers. Little is known about the impact of Acrylamide in food on biomarkers of Acrylamide exposure. Therefore, CDC is conducting a feeding study to investigate the effect of consumption of endogenous Acrylamide in food on biomarkers of Acrylamide exposure. As part of this study, we performed a pilot study to obtain further information on the magnitude of the changes in biomarker levels after consumption of high amounts of potato chips (21 ounces) over a short period of time (1 week) in non-smokers. After 1 week, biomarkers levels increased up to 46% for Acrylamide adducts and 79% for glycidamide adducts. The results indicate that changes in biomarker levels due to consumption of potato chips can be detected. However, because of the design of this pilot study, the observed magnitude of change cannot be generalized and needs to be confirmed in the main study.
