    • BACKGROUND: The response of serum cholesterol to diet may be affected by the apolipoprotein E (APOE) epsilon2/epsilon3/epsilon4 polymorphism, which also is a significant predictor of variation in the risk of coronary heart disease (CHD) and CHD death. Here, we test the hypothesis that the APOE polymorphism may modulate the cholesterol-raising effect of coffee. OBJECTIVE: We determined the effect of a coffee abstention period and a daily intake of 600 mL coffee on serum cholesterol and triglycerides with respect to the APOE polymorphism. DESIGN: 121 healthy, non-smoking men (22%) and women (78%) aged 29-65 years, took part in a study with four intervention periods: 1 and 3) a coffee free period of three weeks, 2 and 4) 600 mL coffee/day for four weeks. RESULTS: APOE epsilon2 positive individuals had significantly lower total cholesterol concentration at baseline (4.68 mmol/L and 5.28 mmol/L, respectively, p = 0.01), but the cholesterol-raising effect of coffee was not influenced significantly by APOE allele carrier status. CONCLUSIONS: The APOE epsilon 2 allele is associated with lower serum cholesterol concentration. However, the APOE polymorphism does not seem to influence the cholesterol-raising effect of coffee.

    • Some methylenetetrahydrofolate reductase (MTHFR) gene polymorphisms are associated with hyperhomocysteinemia. Trials have shown a plasma homocysteine raising effect of coffee. We determined the effect of a daily intake of 600 ml coffee and a supplementation of 200 microg folic acid or placebo on plasma homocysteine (tHcy) with respect to the MTHFR C677T and A1298C polymorphisms. One hundred and twenty healthy, non-smoking men (22%) and women (78%) aged 29-65 years, took part in a controlled, randomized, blinded study with two intervention periods: i) a coffee-free period of three weeks, ii) 600 ml coffee/day and a supplement of 200 microg folic acid/d or placebo for four weeks. The results showed that tHcy at baseline was significantly higher for the 677TT genotype group compared to the 677CC genotype group (p=0.0045) and that this group responded with significantly larger increase in tHcy upon coffee exposure than the 677CC and 677CT genotype groups (p=0.0045 and p=0.0041, respectively). Supplementation with 200 microg folic acid compared to placebo reduced the tHcy increasing effect of coffee in the 677TT genotype group. The A1298C polymorphism did not affect tHcy concentration significantly at any stage in the study. In conclusion, the homocysteine increasing effect of coffee is particularly seen in individuals with the homozygous 677TT genotype. Supplementation with 200 microg folic acid/d decreases this tHcy increment.
