简要总结
Goal is to investigate the differences in skin condition and body composition among women with different dietary habits aged 30-45 years. Study will be focused onto sub-groups of female subjects following omnivorous, vegetarian or vegan diet.
详细描述
Investigators will investigate differences among female subjects aged 30-45 years following one of the following diet for at least 3 years:
- vegan
- vegetarian
- omnivorous
Study will focus into the differences in dermal protein density and dermal thickness, skin hydration and trans-epidermal water loss. Study will focus also into body composition, specifically into % of body fat and % of lean body weight.
