入选标准
- •18 - 30 years of age
- •Healthy or diagnosed with familial hypercholesterolemia (FH) (mutation in gene coding for LDL-receptor). FH subjects can be included if they are:
- •Treated with low dose statin (<20 mg atorvastatin, <10-20 mg simvastatin or <5-10 mg rosuvastatin)
- •Treated with high dose statin and willing to use low dose statin during the last 4 weeks prior to both study visits (total 8 week period)
- •Treated with high dose statins and willing to discontinue statin treatment during the last 4 weeks prior to both study visits (total 8 week period)
- •BMI 18.5 - 30 kg/m2
- •Stabile weight the last three months prior to the first study visit (weight change less than ± 5 % of body weight)
排除标准
- •CRP >10 mg/L
- •TG >4 mmol/L
- •Comorbidities including diabetes type I and II, coronary heart disease, haemophilia, anaemia, gastro intestinal disease, renal failure and hyperthyroidism
- •Pregnant or lactating
- •Allergic or intolerant to gluten or egg
- •Not willing to stop using n-3 fatty acid supplements during the last 4 weeks prior to both study visits
- •Using medications affecting lipid metabolism or inflammation, except statins for FH subjects
- •Hormone treatment (except contraception and thyroxin (stabile dose last 3 months))
- •Donating blood 2 months within or during study period
- •Tobacco smoking
- •Large alcohol consumption (>40g daily)

- Changes in markers of lipid- and glucose metabolism(Measured at baseline and 2,4 and 6 hours after intake of test meal)
- Changes in PBMC Whole genome transcriptomics(Measured at baseline and 4 and 6 hours after intake of test meal)
- Check DNA for single nuclear polymorphisms(Measured at baseline and 2,4 and 6 hours after intake of test meal)
- Changes in circulating levels of inflammatory markers(Measured at baseline and 2,4 and 6 hours after intake of test meal)
- Changes in lipid classes and lipoprotein size(Measured at baseline and 2,4 and 6 hours after intake of test meal)
- Changes in plasma and urine metabolomics(Measured in plasma at baseline and 2,4 and 6 hours after intake of test meal. Measured in urine at fasting state and during the 6 hour postprandial phase.)
