“…Given the overall differences in diet, it is remarkable that there were no differences in serum lipids. Earlier studies have reported that Sami have higher plasma total cholesterol levels (5,32), and lower systolic blood pressure compared to local non-Sami controls (6,33). The BMI for all groups did not differ, which is in contrast to many Indigenous Arctic populations that are in transition from traditional to modern lifestyles, including the Sami as some previous studies have shown (5,32).…”

“…RS also had a lower intake of calcium, which would indicate a lower intake of dairy products, though we found no difference in the total intake of dairy products. Laitinen et al (6) reported that RS in Finland had a higher intake of reindeer meat and lower intake of dairy products, probably due to a traditional lack of access to dairy products. Patterns of nutrient intake in this study were not directly reflected in differences in the intake of different food groups, indicating that differences in choices of specific foods were a key factor in determining differences in nutrient intake.…”

“…A number of studies on the risk of lifestyle-related diseases suggest that Sami have or have had a lower risk of disease when compared to other Fennoscandian populations, including cardiovascular disease (4)(5)(6)(7)(8) and some cancers (4,(9)(10)(11). More recent data suggest that the risk of heart disease and some cancers among Sami is similar or even higher (for Sami women) compared to other local populations (12)(13)(14).…”

“…The consumption of reindeer meat is traditionally relatively high among Sami reindeer herders compared with people of Swedish, Finnish, and Norwegian origin living in the same areas (49,50). Reindeer meat FA composition is suggested to influence the n-6/n-3 ratio and the intake of LCPUFA and thereby affect health.…”

Our aim was to compare the effects of two pelleted diets containing differing FA composition with natural lichen pasture on reindeer's meat FA composition. In addition we wanted to increase the knowledge about reindeer FA metabolism and the effect of animal sex and age on FA composition in reindeer muscle. The trial included five reindeer groups: three grazing, consisting of adult males, adult females, and calves; and two groups of calves fed conventional pellets (CPD) and pellets containing crushed linseed (LPD), respectively, for two months before slaughter. Differences between male and female animals were mainly found in the neutral lipid fraction and related to fatness. Calves differed significantly from adult males and females in FA and lipid class composition. CPD led to a higher ratio of n-6 to n-3 FA compared with grazing. The ratio n-6/n-3 in the polar lipid (PL) fraction of the animals fed LPD was slightly, but not significantly, higher than that in the grazing reindeer. LPD-fed animals had lower proportions of long-chain polyunsaturated FA (LCPUFA), namely 20:4n-6, 22:5n-3, and 22:6n-3, in the PL fraction compared with the grazing animals due to the content of these FA in the natural feed. The animals seemed unable to elongate dietary FA in significant amounts. We conclude that by adding crushed linseed to the pellets it was possible to keep the favorable FA composition of meat from grazing reindeer with regard to the n-6/n-3 ratio but not in LCPUFA.

“…The subjects visited a nurse's office every 2 months at 0900-1100 h. On these occasions blood and urine samples were taken and body weight was measured. A 24 h recall diet interview (Laitinen et al 1996) was also taken by the nurses. Blood samples were centrifuged and stored at 20 C. First-voided urine in the morning of the day of the visit was measured in a graduated cylinder, acidified with 0·1 M HCl and stored in 10 ml portions at 20 C. Blood and urine samples were taken in April (no urine samples), June, August, October, December, February and again in April.…”

In order to evaluate the effects of climatic factors on the secretion of thyroid hormones and TSH in a high latitude population, we have taken serum and urine samples from 20 healthy men from northern Finland (67 -68 N) every 2 months for a period of 14 months. Serum free triiodothyronine (T 3 ) levels were lower in February than in August (3·9 vs 4·4 pmol/l, P<0·05) and TSH levels were higher in December than during other months (2·1 vs 1·5-1·7 mU/l, P<0·01). Serum total and free thyroxine (T 4 ), total T 3 and reverse T 3 levels and urinary T 4 levels were unchanged. Urinary T 3 levels were significantly higher in winter than in summer. Serum free T 3 correlated highly significantly with the outdoor temperature integrated backwards weekly for 7-56 days (r=0·26 for 1-56 days) from the day when the blood samples were taken. Serum TSH did not show any significant correlation with the thyroid hormones or with the integrated temperature of the previous days, but it did show an inverse and significant correlation (r= 0·31) with the ambient luminosity integrated backwards for 7 days from the day when the blood sample was taken. The gradually increasing correlation between outdoor temperatures and serum free T 3 suggests that the disposal of thyroid hormones is accelerated in winter, leading to low serum free T 3 levels and a high urinary free T 3 excretion. Since there was no correlation between thyroid hormones and serum TSH, the feedback mechanism between TSH and thyroid hormones may not be the only contributing factor, and other factors such as ambient luminosity may at least partly determine serum TSH in these conditions. Also urinary free T 3 appears to be a novel and non-invasive indicator for thyroid physiology.
