Am J Clin Nutr. 2004;80:862-7. De Bacquer D, Clays E, Delanghe J, De Backer G. Epidemiological evidence for an association between habitual tea consumption and markers of chronic inflammation.

2 Background Inflammation is important to the development of cardiovascular disease (CVD). The effect of coffee consumption on the cardiovascular system is conflicting. Inflammation is important to the development of cardiovascular disease (CVD). The effect of coffee consumption on the cardiovascular system is conflicting. Tea consumption has been inversely related to the risk of CVD. In vitro and animal model studies suggest an anti- oxidative and/or anti-inflammatory role of tea.

4 Coffee drinking Design: 1514 men and 1528 women. No history of CVD. Blood consentrations of APPs. Design: 1514 men and 1528 women. No history of CVD. Blood consentrations of APPs. Results: Coffee drinkers (>200 ml/d) vs. nondrin. Results: Coffee drinkers (>200 ml/d) vs. nondrin. C-reactive protein (CRP) higher (p<0.05) C-reactive protein (CRP) higher (p<0.05) serum amyloid-A (SAA) higher (p<0.05) serum amyloid-A (SAA) higher (p<0.05) The findings were significant after control of age, sex, smoking, body mass index, physical activity status, and other covariates The findings were significant after control of age, sex, smoking, body mass index, physical activity status, and other covariates Conclusions: A relation exists between moderate- to-high coffee consumption and increased inflammation process. This relation could explain, the effect of increased coffee intake on the CVD Conclusions: A relation exists between moderate- to-high coffee consumption and increased inflammation process. This relation could explain, the effect of increased coffee intake on the CVD

5 Tea drinking Design: 1031 healthy men in a larger cross- sectional study. Blood APPs concentrations. Design: 1031 healthy men in a larger cross- sectional study. Blood APPs concentrations. Results: Tea drinkers were less obese, smoked less and drank less alcohol and coffee. Results: Tea drinkers were less obese, smoked less and drank less alcohol and coffee. CRP, SAA and haptoglobin were significantly negatively associated with tea consumption. CRP, SAA and haptoglobin were significantly negatively associated with tea consumption. Multivariate analysis did confirm the independence of the observed beneficial role of tea drinking. Multivariate analysis did confirm the independence of the observed beneficial role of tea drinking. Coffee drinking unrelated to inflammation. Coffee drinking unrelated to inflammation. Conclusion: Tea drinking might be of interest in reducing the inflammatory process underlying cardiovascular disease.

7 Bovine respiratory disease complex - BRD BRD is a multifactorial disease complex, caused by a variety of etiological agents which acts synergistically (viruses, bacteria, mycoplasmas).

Environmental and husbandry factors as Environmental and husbandry factors as well as impaired resistance of calves to infections are involved as predisposing factors
