宇宙など微小重力環境における人体への健康状態への影響に赤ワインの成分が効果があることが明らかになったそうだ (Discovery News、本家 /. 記事より) 。 人間は微小重力環境におかれると骨量減少、免疫力低下、筋肉量の減少や脱水症状、また循環系機能の低下などを引き起こすという。フランスの研究チームはこの度レスベラトロルという赤ワインに含まれる抗酸化成分がこれらの微小重力下独特の症状に効くことを突き止めたという。この成分は悪玉コレステロール値を下げたり、血栓が形成されるのを防いだりする効果があることが分かっていたが、微小重力環境を模倣したマウスを使った実験で骨量減少や筋萎縮も防ぐことが明らかになったとのこと。なお、微小重力環境はマウスを尻尾で逆さまにつり下げることで実現したとのことだ。 ただし、効果を期待するには大量の赤ワインを飲む必要があるとのことで、実際にはサプリメント形式での
