最近,在英国国家食品工艺学院举行的由化学家、生化学家以及临床学家等参加的会议上明确指出:维生素 C 的大剂量应用(每天至少1克)对人体并无危害。维生素 C 的有效作用可能包括:减少普通感冒和流感的罹病率;降低血液胆固醇水平;避免由于亚硝胺引起的癌症;增进免疫反应以及晚近发现的提高精神活动的机敏性(boost-ing mental alertness)。 Recently, at a conference attended by chemists, biochemists and clinicians held at the National Institute of Food Technology in the United Kingdom, it was clearly stated that the high dose of vitamin C (at least 1 gram per day) is not harmful to the human body. The effective effects of vitamin C may include: reducing the prevalence of common cold and flu; lowering blood cholesterol levels; avoiding cancers caused by nitrosamines; enhancing immune responses and the recently-discovered mental alertness ).
