Introduction:
Several epidemiological studies have reported inconsistent findings on the association between carotenoid intake and fracture risk. This study aimed to determine the association between individual carotenoid intake and fracture risk.
Methods:
A cross-sectional study based on data from the National Health and Nutrition Examination Survey (NHANES), 2013-2018. This study identified elderly individuals with valid and complete data on carotenoid intake and fracture risk. The average dietary intakes of α-carotene, β-carotene, β-cryptoxanthin, lycopene, and lutein + zeaxanthin was taken based on the two 24-hour recall interviews. Matching was done based on age, sex, and body mass index (BMI). Logistic regression models were used to test the associations between carotenoids and fracture risk. All analyses were performed by using R (version 3.4.3; R Foundation for Statistical Computing, Vienna, Austria).
Results:
A total of 5491 (1140 cases and 4351 control) subjects were included in this study. The average age of the subjects was 55.62 ± 14.84 years old. In the adjusted model, the risk of osteoporotic fracture was decreased by 6.2% (odd ratio (OR): 0.938; 95% confidence interval (CI): 0.699 to 0.989) and 1.4% (OR 0.986; 95% CI: 0.975 to 0.997) for dietary intake of beta-carotene and lycopene, respectively.
Conclusions:
Dietary intakes of beta-carotene and lycopene have significantly reduced the risk of osteoporotic fracture among the elderly population in the United States of America.

01:25Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
