Description
Inclusion Criteria:
- 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:
- Untreated
- 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)
Exclusion Criteria:
- 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)
