Skin aging and calcium
The human epidermal provides a very effective barrier function against chemical, physical and microbiology result from the environment. This is only possible as the epidermis renews itself constantly, which forms a derma epidermal junction, provides an almost inexhaustible source of keratinocytes that differentiate and die during their journey to the surface.
Despite the continuous renewal of the epidermis is never the less succumbs to aging as the turnover rate of keratinocytes is slowing down dramatically. Aging is associated with such hallmarks as thinning of the epidermis, elasticity, loss of melanin cytes associated with an increased paleness and lucency of the skin, and a decrease barrier function.
Calcium is an essential nutrient that is necessary for many functions in human health. Calcium is the most abundant mineral in the body with 99% found in teeth and bone and only 1% found in serum. Calcium involves nutrients like protein, vitamin D, and phosphorus. Bone formation is a lifelong process. Early attention to the strong bone in childhood and adulthood will provide more stable bone mass during the aging years. Research has shown that adequate calcium intake and reduces the risk of fracture, osteoporosis, and diabetes in some populations.
The dietary requirement of calcium and other collaborative nutrients varies slightly around the world. Lactose intolerance due to lactase deficiency is a common cause of low calcium intake.
The three organ systems are the kidney, the intestine, and the bone.
The kidney is the primary mechanism for rapid release or absorption of calcium through the filtration and wine excretion functions.
Approx. 200 mg per day is typically excreted by others through the kidneys via urine but varies by diet and serum parameters.
The second organ system, the intestine is slower in response. Daily dietary intake of 1000 mg of calcium would potentially result in 800mg available for tissues nutrient and 200 to maintain serum calcium levels. The extraintestinal calcium can be processed through the kidneys and removed from the body through urine excretion.
In the third system, calcium can move both into and from the bone matrix. The flexible bone pool varies by body size and bone density, typically has available calcium of approximately 150 to 200 gram, if more is required, actually bone calcium must be released from the bone Matrix and used to maintain serum calcium. Replacement of borrowed calcium does not always ensure your similar bone composition.
