- AimTo evaluate the effect of the daily intake of a fruit & vegetable soup with high in vitro bioaccessibility of carotenoids on β-carotene and lycopene serum concentrations.MethodsFourteen healthy young men (24 ± 1 years) received 300 mL/day of a carrot, tomato, and broccoli soup, containing 3.9 mg β-carotene and 4 mg lycopene, for 4 weeks followed by a 4-week washout period. The serum carotenoid response and oxidative markers were analyzed after 3 and 4 weeks of soup consumption and after a 4-week washout.ResultsThe in vitro bioaccessibility of β-carotene and lycopene was 55 and 43%, respectively, in the soup. Serum β-carotene concentrations were significantly higher than baseline (0.33 ± 0.05 μmol/L) after 3 weeks (0.69 ± 0.06 μmol/L) and 4 weeks (0.78 ± 0.10 μmol/L) of soup consumption (P

- The maintenance of an obtained lower weight level is often found to be difficult. The aim of this study was to determine weight maintenance after an initial weight loss by consumption of a meal replacement with a vegetable-oil emulsion associated with prolonged satiety. After a 6-week weight loss period with very low calorie diet (VLCD), subjects with > 5% body weight (BW) loss were randomized to a 12-week weight maintenance follow-up period, comparing a partial meal replacement diet containing a vegetable-oil emulsion (test) or dairy fat (control). Anthropometric data and safety variables were collected at baseline and after 4, 8 and 12 weeks. A significant weight loss was observed during the 12-week weight maintenance diet in the test and control group, respectively; 1.0 +/- A 2.1 kg (p < 0.05) versus 1.3 +/- A 2.1 kg (p < 0.05) with no significant difference between the groups. Body fat mass (BFM) decreased significantly (p < 0.05) in the test group (-1.7%) compared to the control group (-0.8%). Addition of a vegetable-oil emulsion to a meal replacement weight maintenance program after an initial weight loss using VLCD was associated with decreased BFM by 0.9% without any change in BW between the two groups.

- Objectives: The aim of the present study was to investigate whether the following four markers; Vitamin B12, selenium, vitamin D, and parvalbumin may be used as compliance markers for fish intake. Methods: Blood samples from a randomized cross-over herring intervention study (n=32) were analyzed by HPLC and immunochemistry. The criteria were that plasma or serum concentrations of candidate compliance markers after the herring diet should increase significantly compared to starting concentrations. In addition, the reference meat diet should not yield an increase in plasma concentration of the candidate marker. Results: Vitamin B12 and selenium met the set criteria for indicating a correlation between the marker and fish intake with significant increases in serum concentrations at 8.9% (p=0.008) and 4.6% (p=0.02) respectively after a 6-week herring intervention (5 meals a week). Parvalbumin and 25-hydroxy vitamin D3 levels did not increase significantly during the herring interventions. Conclusions: Vitamin B12 may be suitable as a compliance marker for fish intake. Although selenium also met the criteria, the change in selenium serum concentrations was small compared to the change in vitamin B12 levels.

Is a daily supplementation with 40 microgram vitamin D(3) sufficient? A randomised controlled trial

- Purpose The effect of 40 μg (1,600 IU) per day of vitamin D3 on serum 25-hydroxyvitamin D (25(OH)D) and markers of bone and mineral metabolism was evaluated. Methods This intervention study was designed as a double-blind randomised controlled trial. Forty-five community-dwelling subjects (32 females), age 55–84 years, at 58° North latitude were supplemented for 1 year with 40 μg vitamin D3 plus 1,000 mg calcium per day, or with 1,000 mg calcium per day for controls. Safety parameters and 25(OH)D, intact parathyroid hormone (PTH), ionized calcium, bone-specific alkaline phosphatase (BALP), and tartrate-resistant acid phosphatase isoform 5b (TRACP5b) were measured over the study period. Results All subjects supplemented with vitamin D3 reached a 25(OH)D level above 50 nmol/L. Mean (SD) serum 25(OH)D increased from 50.4 (13.5) nmol/L to 84.2 (17.5) nmol/L, range 55.0–125.0 nmol/L in the vitamin D3 supplemented group and the corresponding levels for the control group were 47.3 (14.1) nmol/L and 45.7 (13.4) nmol/L, range 26.0–73.0 nmol/L. No serious adverse event was recorded and the highest 25(OH)D level reached, 125.0 nmol/L, is well below toxic levels. BALP and TRACP5b did not change significantly over the study period. Conclusions This trial suggests that a daily supplementation with 40 μg vitamin D3 is sufficient to secure a 25(OH)D level of 50 nmol/L. No side effects were observed in the study group.

- PURPOSE:To evaluate how long-term dietary intake of long-chain n-3 polyunsaturated fatty acids (LCn-3 PUFAs), estimated by repeated food frequency questionnaires (FFQs) over 15 years, is correlated with LCn-3 PUFAs in adipose tissue (AT).METHODS:Subcutaneous adipose tissue was obtained in 2003-2004 (AT-03) from 239 randomly selected women, aged 55-75 years, after completion of a 96-item FFQ (FFQ-03). All participants had previously returned an identical FFQ in 1997 (FFQ-97) and a 67-item version in 1987-1990 (FFQ-87). Pearson product-moment correlations were used to evaluate associations between intake of total and individual LCn-3 PUFAs as estimated by the three FFQ assessments and AT-03 content (% of total fatty acids).RESULTS:FFQ-estimated mean relative intake of LCn-3 PUFAs (% of total fat intake) increased between all three assessments (FFQ-87, 0.55 ± 0.34; FFQ-97, 0.74 ± 0.64; FFQ-03, 0.88 ± 0.56). Validity, in terms of Pearson correlations between FFQ-03 estimates and AT-03 content, was 0.41 (95 % CI 0.30-0.51) for total LCn-3 PUFA and ranged from 0.29 to 0.48 for individual fatty acids; lower correlation was observed among participants with higher percentage body fat. With regard to long-term intake estimates, past dietary intake was also correlated with AT-03 content, with correlation coefficients in the range of 0.21-0.33 and 0.21-0.34 for FFQ-97 and FFQ-87, respectively. The correlations were improved by using average estimates from two or more FFQ assessments. Exclusion of fish oil supplement users (14 %) did not alter the correlations.CONCLUSION:These data indicate reasonable validity of FFQ-based estimates of long-term (up to 15 years) LCn-3 PUFA intake, justifying their use in studies of diet-disease associations.

- Cord serum (CS) phospholipid fatty acid composition is associated with maternal diet during foetal life, and maternal intake of linoleic acid (LA, C18:2 omega-6) and alpha-linolenic acid (LNA, C18:3 omega-3) has been shown to influence the LA and LNA levels in CS. A possible connection between the increased incidence of atopic diseases and increased intake of LA and decreased intake of LNA in the Western world has been proposed. less thanbrgreater than less thanbrgreater thanThe aim of this study was to explore phospholipid fatty acid proportions and total IgE levels in CS from Swedish children, collected from 1985 to 2005, a period with increasing frequency of allergic diseases in Sweden, and reveal possible changes over time. less thanbrgreater than less thanbrgreater thanPhospholipid fatty acids and total IgE antibodies were analysed with gas chromatography and UniCAP(A (R)) technology, respectively, in 300 CS samples. less thanbrgreater than less thanbrgreater thanThe proportions of LA and LNA decreased significantly from 1985 to 2005 (p andlt; 0.001 for both).
