충치는 식품의 당질과 치아 플라그의 세균 사이의 상호작용의 결과이다. 플라그의 세균은 설탕과 같은 발효 가능한 당질을 유기산으로 분해한다. 이러한 산생성은 플라그의 pH를 저하시켜 충치가 시작되는데, pH 5.7 이상에서 치아는 안전하고 그 이하에서는 충치가 발생할 수 있다. 치즈는 다른 식품과 비교해서 충치효과의 가능성이 가장 적었다. 치즈가 충치효과가 적을 뿐 아니라 충치를 예방할 수 있는 가능성이 충분히 있다. 치즈에 풍부하게 존재하는 칼슘과 인이 이 과정에 작용하여 치아 건강에 탁월한 식품으로서 기능을 수행한다.

Background: The relative importance of body composition, lifestyle factors, bone turn-over and hormonal factors in determining bone mineral density (BMD) is unknown. Westudied younger postmenopausal women to determine whether modifiable or non-modifiable risk factors for osteoporosis have stronger associations with BMD. Methods: In multivariable linear regression models, we tested associations betweennon-bone body composition measures, self-reported measures of physical activity anddietary intake, urinary N-telopeptide (NTx), sex hormone concentrations, and BMD in109 postmenopausal women aged 50 to 64 years, adjusting for current hormone thera-py use and clinical risk factors for low BMD. Lean mass, fat mass and areal BMD (aBMD)at the lumbar spine, femoral neck, total hip and distal radius were measured using dualenergy X-ray absorptiometry. Results: Higher body weight and self-reported nonwhite race were independently asso-ciated with higher aBMD at the lumbar spine, femoral neck, total hip and distal radius. Lean and fat mass were not independently associated with aBMD. Older age and higherurinary NTx were independently associated with lower aBMD at the distal radius but notat weight-bearing sites. Sensitivity analyses demonstrated lack of an independent asso-ciation between total daily protein or calorie intake and BMD. Conclusions: BMD, weight and race were the most important determinants of aBMD atall sites. Older age and higher bone turnover were independently associated with loweraBMD at the distal radius. In a limited analysis, self-reported physical activity, dietaryprotein and calorie intake were not associated with aBMD after adjustment for the othervariables.
