“…In conclusion, the present 13 C and 15 N analyses in Inuit and Danes are by and large in accordance with the dietary patterns assessed by dietary surveys (Haraldsdó ttir et al, 1987;Deutch et al, 2007). Our results show that Inuit showed considerable variation in the ratio between the consumption of marine-terrestrial diet.…”

“…This finding is consistent with the fact that the elderly Inuit population during their lifetime consume more of the traditional Greenlandic diet (hunters food) than the younger urbanized Inuit population who consumes a western-style diet (Deutch et al, 2007). Men showed a significantly higher d 13 C value in the cellular fraction than women, probably because of a higher consumption of marine food.…”

“…Our results show that Inuit showed considerable variation in the ratio between the consumption of marine-terrestrial diet. This variation reflects a vanishing hunter culture where elderly Inuit still adhere to the traditional Greenlandic hunters food with a high content of food of marine origin, whereas the younger urbanized Inuit population during the past four decades to an increasingly extent consume western fare with a low content of marine and a high content of terrestrial food (Deutch et al, 2007). Danes consumed food of almost exclusively terrestrial origin.…”

“…In the marine milieu, the connecting links to the human food chain are marine fish, marine mammals (seal, walrus and whale) and marine birds, which constitute the main components in the traditional hunters food in Greenland (Buchardt et al, 2007;Deutch et al, 2007).…”

Background/Objectives: The content of 13 C and 15 N isotopes is higher in marine than in terrestrial food. 13 C and 15 N in human tissue therefore reflects the relative proportions of marine and terrestrial food consumed by the individual. The objective of this study was to measure 13 C and 15 N in liver tissue from Greenlandic Inuit and Danes. Subjects/Methods: Normal liver tissue was obtained at autopsy in 1992-1994 from 60 Inuit with a median age of 61 years (range 25-83) and in 1986 from 15 ethnic Danes with a median age of 84 years (range 66-93). By sieving, liver tissue was separated in a 'cellular fraction' and a 'connective tissue fraction'. 13 C and 15 N in dry liver tissue was measured on a mass spectrometer. d 13 C indicates the 13 C content relative to the IAEA-CH-6 reference standard. d 15 N indicates 15 N content relative to the atmospheric nitrogen reference standard. Results: Inuit: median d 13 C was À21.2% in cellular and À20.0% in connective tissue fractions (P ¼ 0.001). Median d 15 N was 10.6% in both cellular and connective tissue fractions. Body mass index was negatively correlated with d 13 C in the connective tissue fraction (r s ¼ À0.42, P ¼ 0.057). Danes: median d 13 C was À27.0% in cellular and À24.3% in connective tissue fractions (P ¼ 0.11). Median d 15 N was 9.5% in cellular and 8.9% in connective tissue fractions (P ¼ 0.5). Inuit had higher d 13 C than Danes in both cellular and connective tissue fractions (Po0.001) as well as higher d 15 N in the cellular fraction (P ¼ 0.01). Conclusions: Inuit showed considerable variation in the ratio between marine and terrestrial food consumption, reflecting a vanishing hunter culture where elderly Inuit still adhere to the traditional hunters food with a high content of marine food, whereas the younger urbanized Inuit population consume food with a lower content of marine food and a higher content of terrestrial food. Danes consumed food of almost exclusively terrestrial origin. The present 13 C and 15 N analyses are in accordance with the dietary patterns obtained by dietary surveys.

We carried out an exhaustive review regarding human skin color variation and how much it may be related to vitamin D metabolism and other photosensitive molecules. We discuss evolutionary contexts that modulate this variability and hypotheses postulated to explain them; for example, a small amount of melanin in the skin facilitates vitamin D production, making it advantageous to have fair skin in an environment with little radiation incidence. In contrast, more melanin protects folate from degradation in an environment with a high incidence of radiation. Some Native American populations have a skin color at odds with what would be expected for the amount of radiation in the environment in which they live, a finding challenging the so‐called “vitamin D–folate hypothesis.” Since food is also a source of vitamin D, dietary habits should also be considered. Here we argue that a gene network approach provides tools to explain this phenomenon since it indicates potential alleles co‐evolving in a compensatory way. We identified alleles of the vitamin D metabolism and pigmentation pathways segregated together, but in different proportions, in agriculturalists and hunter‐gatherers. Finally, we highlight how an evolutionary approach can be useful to understand current topics of medical interest.
