Beer boosts blood concentrations of vitamin B6, a new study finds. This vitamin is required for the processing of amino acids and formation of chemicals essential for brain function. It also can break down homocysteine, an amino acid metabolite that has been identified as a heart-disease risk factor.
Dutch researchers tracked vitamin B6 concentrations in 11 men over 12 weeks. For 3-week periods, each man consumed with dinner four servings of either red wine, beer, gin, or mineral water. The regimens were switched every 3 weeks. The four beer servings totaled one liter. The researchers provided the volunteers a diet that didn't vary during the study.
