Calorie restriction skin benefits
Aged refed mice in that study healed at rates similar to the young AL fed mice. In the present experiments and in an earlier study, similar UV-B influences were observed; dietary alterations seemed to modify many of these UV-B—mediated responses affecting different components of the mouse skin. Table 2 summarizes the qualitative grading based on the quantitative results. Lane et al. For processing consistency, all skin samples from each group were embedded in the same paraffin block before microscopic morphometry. The results achieved in the RF group suggest that increasing nutrition, i. Intact control and obesity control animals had almost identical percentages of elastic fibers. Toward a unified theory of caloric restriction and longevity regulation. J Nutr. Is there any dietary influence on UV-B—induced changes in skin histological features?
Caloric restriction diets have been associated with health benefits, but their effects on the skin have not been previously demonstrated. One of the first studies to explore the effects of calorie restriction on humans showed that cutting caloric intake by 15% for 2 years slowed aging. "There is a lot of evidence to support the benefits of a restricted-calorie diet in rats Societal impact aside, Delaney suggests the benefit of calorie restriction is.
Other mouse studies have shown UV-induced damage to mature collagen in the upper dermis or a loss of collagen.
Also, a dramatic loss in body weight seen herein in UV-B—exposed Cr mice, which may be a stress response from metabolic or endocrine modifications, is comparable to the findings in some published reports on rodents as described below.
Obesity diet influence was predominantly noted on epidermal thickness and epidermal PCNA index. Methodological details have been described in another article. Main Outcomes and Measures Histomorphometric analysis was performed on paraffin-embedded skin sections stained by histological and immunohistochemical methods for estimation of epidermal thickness, epidermal proliferating cell nuclear antigen index, collagen I, elastic fibers, fibroblasts, mast cells, dermal cellularity, and adipose layer ratio.

Sidebar: For More Information - Caloric Restriction's Benefits Caloric restriction ( CR) of aging called pentosidine, a chemical compound found in skin collagen. Caloric restriction results in a longer and healthier life, but is it possible to counteract the aging process of the skin the same way?
The first evidence indicating the benefits of CR date back to the s in studies conducted.
ScienceDaily, 22 March Skin aging changes in animal models: a histological perspective. Table 1 summarizes the results of the F ratio, the level of significance, and comparison of relevant groups.
Control animals were fed a normal diet that was nutritionally complete and purified TD ; Harlan Laboratories. Life span extension and food restriction.
