章节摘录
插图:Vitamins are important for good health. These complex organic substances help to carry out chemical changes within cells. If we do not get enough of the vitamins we need in our food, we are at risk of developing a number of diseases.Some shrinkage of the brain is thought to happen normally as people grow older. Yet studies have shown a link between a larger shrinkage and Alzheimer's disease.The Oxford researchers tested one hundred and sixty-eight people over twenty-four months. All of those tested were over age seventy. One group in the study took B vitamins every day. They swallowed tablets containing folic acid, vitamin B-6 and vitamin B-12. A second group took placebos——harmless substances that did not contain the vitamins or folic acid.Two years later, the researchers used magnetic resonance imaging tests to study both groups. They also tested the thought processes of each person. Those taking the vitamins had up to fifty percent less brain shrinkage than those taking the placebos.Professor Smith says the researchers chose B vitamins for the study because they control homocysteine, an amino acid in the blood. Earlier studies have linked high homocysteine levels to a greater risk of Alzheimer's.The Oxford researchers say about one in six people over age seventy has problems with mental operations. They say half of these people develop serious loss of mental ability, as in Alzheimer's disease. Over time, the disease robs people of their memories. Finally, it takes away their ability to care for themselves.
