Sales of health supplements have soared in recent years. It’s such a huge market that manufacturers spend around £40 million a year just telling us about their products. As supplements are either made from natural substances or mimic substances produced by our bodies, many people assume they cannot do any harm. But we’re wrong, say health professionals. They point out that the health supplement industry is unregulated, which means manufacturers are not required to list potential side-effects – nor do their products have to go through costly clinical trials. “Health supplements can produce ill effects,” warns Anna, from the British Dietetic Association. 保健品的销售量在近几年大幅飙升。这真是一个巨大的市场，厂家每年花费4000万仅为了宣传他们的产品。补品要么是天然物质制造的，要么是来自我们身体的变种物，所以许多人认为它们不会造成任何伤害。但健康专家说我们错了。他们指出保健品产业是未调节的，也就是说生产商不需提供产品的潜在负面信息，也不需经过昂贵的临床试验。“保健品可能造成不良影响。”来自英国饮食协会的安娜说。 |
