Abstract:
In lifestyle-related common diseases, Diabetes mellitus is known to cause not only atherosclerosis and cardiovascular events but also bone fragility and high fracture risk. Advanced glycation endproducts (AGEs), which are deeply involved in diabetes pathogenesis, experimentally induce the calcification of aortic smooth muscle, while suppressing the osteoblastic differentiation and calcification of marrow stromal cells. AGEs also clinically and adversely affect fracture risk in diabetic patients. In contrast, bone deterioration is positively linked to the aggravation of lifestyle-related common diseases by diminishing in osteoblast-specific osteoclacin and Wnt signal, which increases blood glucose and triglyceride levels, and aggravates atherosclerosis.

Bone 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...
Essential Minerals for Bone Health
Calcium and Phosphorus
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...
Role 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...
