Food is the only medicine that the average healthy individual requires on a daily basis Indeed, more than 2000 years ago, Hippocrates is said to have offered: Let food be your medicine, and let medicine be your food 1 It is from such a perspective that good nutrition is a fundamental building block of good general health and healthy skin that this discussion proceeds Specifically, this chapter will focus on some of the key chemical components of a healthy diet that have been shown to confer benefits to the skin In the process, cutaneous effects will be discussed in the context of vegetarianism, as well as the skin types of the Baumann Skin Typing System Attention will first be focused on the effects of diet on acne, the most common dermatologic condition, and, finally, on oral supplementation There is copious research underway now on the direct effects on health from the consumption or supplementation of various nutrients A significant proportion of such work focuses specifically on the potential benefits conferred to the skin through the intake of certain foods or supplements For instance, in 2003, a cross-sectional study of 302 healthy men and women collected data on serum concentrations of nutrients, dietary consumption of nutrients, as well as various cutaneous measurements (including hydration, sebum content, and surface pH), revealing statistically significant relationships between serum vitamin A and cutaneous sebum content as well as surface pH as well as between skin hydration and dietary consumption of total fat, saturated fat, and monosaturated fat The investigators concluded that such findings are evidence that the condition of the skin can be influenced by alterations in baseline nutritional status2 recently, estimates of acne prevalence and incidence in Western populations, while remaining high, have come closer to 17 million in the United States4,5 (see 15) Interestingly, recent epidemiologic studies in non-Westernized populations (ie, Inuit, Okinawan Islanders, Ache hunter-gatherers, and Kitavan Islanders) in which acne is rare, indicate that dietary factors, including glycemic load, may play a role in the development of this condition, particularly since incidence of acne has risen in these communities in association with the adoption of Western lifestyles6 9 Accordingly, Cordain, has argued persuasively for abandoning the traditional belief espoused in the dermatology community since the early 1970s that diet does not contribute to the pathophysiology of acne In particular, he asserts that the dogma claiming that diet and acne are unrelated has been based on two fundamentally flawed studies from 1969 by Fulton et al and 1971 by Anderson that lacked control groups, statistical data treatment, as well as blinding and/or placebos and were characterized by inadequate sample sizes and insufficient or absent baseline diet data, among other deficiencies6,10,11 Furthermore, Cordain contends that substantial evidence has been amassed since these two influential studies revealing that alterations in hormonal and cytokine homeostasis engendered by diet have emerged as the leading candidates for exogenous influences on acne development Among such data is a study suggesting that the regular, longterm consumption of high glycemic meals, which raise insulin concentrations, may induce chronic hyperinsulinemia and insulin resistance, increasing levels of insulin-like growth factor 1 (IGF-1) and decreasing levels of insulinlike growth factor binding protein 3 (IGFBP-3), fostering keratinocyte proliferation and corneocyte apoptosis6,12,13 Other proximate causes of acne, such as androgen-mediated sebum production levels as well as inflammation, are also affected by diet Cordain notes that insulin and IGF-1 incite the synthesis of androgens as well as sebum and inhibit the hepatic production of sex hormonebinding globulin, resulting in higher levels of circulating androgens6 In 2007, Smith et al investigated the effects of a low-glycemic-load diet on acne lesion counts in 43 males between the ages of 15 and 25 years The experimental diet, over the 12-week, parallel design study with investigator-blinded skin evaluations, included 25% energy from protein and 45% from lowglycemic-index carbohydrates and the control group diet focused on carbohydrate-rich foods without regard to the glycemic index The low-glycemic-load participants experienced larger reductions in the number of acne lesions, weight, and body mass index and a greater improvement in insulin sensitivity than the subjects consuming the control diet14 In the same cohort of patients, Smith et al also compared the impacts from an experimental lowglycemic-load diet with those from a conventional high-glycemic-load diet on acne Subjects following the intervention diet, which included recommendations to eat more fish, exhibited lower lesion counts than the high-glycemic control group after 12 weeks, and experienced greater reductions in weight and free androgen index in addition to elevated insulin-like growth factor binding protein-1 as compared to controls While calling for additional research, the investigators concluded that these findings reflect an active role in acne etiology of nutritional choices15 While accepting this overarching argument by Smith and colleagues, Logan suggested in response that aspects other than a low-glycemic index in the experimental diet, particularly its status as being lower in saturated fats as well as much higher in polyunsaturated fats and fiber, may account for hormonal alterations and inflammation that affect acne16 He added that greater consumption of fish, which contains anti-inflammatory omega-3 fatty acids, may have rendered the intervention diet higher in polyunsaturated fats and had a mitigating effect on acne To further this work by Smith et al, Logan recommended research using high-fiber, high-omega-3 fatty acid, and low saturated-fat diets Such concerns were at least partially answered by a more recent report by Smith et al An investigation using data on the same patients revealed a correlation between an elevated ratio of saturated to monounsaturated fatty acids of skin surface triglycerides and decreased acne lesion counts in the low-glycemicload diet group as compared to controls after 12 weeks An increase in monounsaturated fatty acids in sebum was also associated with greater sebum secretions The authors concluded that desaturase
