Health and happiness among homosexual couples in Europe.

Data from five waves (2002-10) of the European Social Survey were examined to see the extent to which heterosexual and homosexual couples differ in their health and happiness. Homosexual people had lower levels of self-rated health and happiness. We suggest that those who experience discrimination are more strongly integrated in their gay community, which, in turn, may bring positive effects in terms of happiness due to a sense of belonging, but may be accompanied by the specific health risks associated with this community.

Validity of dual-label stable isotopic protocols and urinary excretion ratios to determine folate bioavailability from food.

We tested the hypothesis that some cereal-product vehicles may reduce fortificant bioavailability below 85% and examined the feasibility of using single dose, dual-label, non-saturation protocols for studying bioavailability based on urinary excretion ratios (UER; % oral 13C6 isotope dose excreted in intact folate/% i.v. 2H4 isotope dose excreted).
