<p>The aim was to investigate the effects of increased water or dairy intake on total intake of energy, nutrients, foods and dietary patterns in overweight adolescents in the Milk Components and Metabolic Syndrome (MoMS) study (<i>n</i>=â173). Participants were randomly assigned to consume 1l/d of skim milk, whey, casein or water for 12 weeks. A decrease in the dietary pattern called Convenience Food, identified by principal component analysis, was observed during the intervention both in the water and dairy groups. Total energy intake decreased by 990.9âkJ/d (236.8âkcal/d) in the water group but was unchanged in the dairy group during intervention. To conclude, an extra intake of fluid seems to favourably affect the rest of the diet by decreasing the intake of convenience foods, including sugar-sweetened beverages. A low energy drink, such as water, seems advantageous considering the total energy intake in these overweight adolescents. This study is registered at clinicaltrials.gov (NCT00785499).</p
Vitamin Dâvitamin K interaction: effect of vitamin D supplementation on serum percentage undercarboxylated osteocalcin, a sensitive measure of vitamin K status, in Danish girls
There is some evidence for a nutritional interaction between vitamin D and vitamin K status. We have recently reported that serum percentage
undercarboxylated osteocalcin (%ucOC; a marker of vitamin K status) was inversely correlated with serum 25-hydroxyvitamin D (25(OH)D)
concentration (reflective of vitamin D status) in healthy Danish girls (aged 11â12 years), in line with a similar relationship reported in elderly
women. While the causal nature of the relationship between vitamin D status and serum %ucOC has been tested in studies of elderly women,
it has not been investigated in children. The objective of the present study was to test the hypothesis that improving vitamin D status significantly
lowers serum %ucOC. Serum samples from sixty-seven healthy Danish girls (aged 11â12 years), who participated in a 12-month double-blind,
placebo-controlled, vitamin D3 intervention trial were used for the present study. These girls were a subset of subjects which began and finished the
intervention during wintertime, thus avoiding the influence of seasonality on vitamin D status. A total of thirty-three and thirty-four of the girls had
been randomised to treatment with 10 mg vitamin D3 per d and placebo, respectively, for 12 months. Total osteocalcin and the fraction of ucOC in
serum (via enzyme-immunoassay) as well as serum 25(OH)D (via HPLC) were assessed at baseline and end-point. Vitamin D3 supplementation
significantly increased serum 25(OH)D (21¡6 %; P,0¡002) but had no effect on serum %ucOC (P.0¡8). In conclusion, the findings of the present
intervention study in young girls suggest that vitamin D supplementation does not affect serum %ucOC, a marker of vitamin K status
Serum percentage undercarboxylated osteocalcin, a sensitive measure of vitamin K status, and its relationship to bone health indices in Danish girls
Recent cross-sectional data suggest that better vitamin K status in young girls (aged 3â16 years) is associated with decreased bone turnover, even though it is not associated with bone mineral content (BMC). The objective of the present study was to investigate the relationship between serum percentage of undercarboxylated osteocalcin (%ucOC), as an index of vitamin K status, and BMC and biochemical indices of bone turnover in peri-pubertal Danish girls. This peri-pubertal stage is a dynamic period of bone development, and as such, may represent an important window of opportunity for vitamin K status to modulate childhood bone health. Serum %ucOC and serum 25-hydroxyvitamin D (25 (OH) D) were measured at baseline in a study of 223 healthy girls aged 11â12 years. Urinary pyridinium crosslinks of collagen and serum total osteocalcin as markers of bone resorption and formation, respectively, as well as BMC (total body and lumbar spine) were also measured. Serum %ucOC (median 21¡9 %) was not associated with markers of bone resorption or with total osteocalcin. Serum %ucOC was inversely correlated with serum 25 (OH) D (r â 0¡143; P < 0¡05). Serum %ucOC was negatively associated with BMC of the total body (β â 0¡045; P < 0¡001) and lumbar spine (β â 0¡055; P < 0¡05), after adjustment for potential confounders including vitamin D status. Better vitamin K status was associated with increased BMC, but not bone turnover, in healthy peri-pubertal Danish girls. There is a need for well-designed, randomized phylloquinone supplementation trials in children and adolescents to confirm epidemiological findings of an association between vitamin K status and bone health
