A 46-year-old salaried man bought canned essence of clam to drink in the hope of strengthening his liver, which he believed had been weakened by frequent overtime at work.
Unexpectedly, things turned out much worse after he took the concentrated drink every day for a week. His gout deteriorated, making his toes and ankles painful and swollen. He suspected the drink was the source of his troubles.
When this news broke last month, it sent shock waves through the burgeoning essence of clam market and triggered public concern about whether the product was really as safe as the producers had claimed.
On the Web site of the state-run Taiwan Sugar Corp (Taisugar,
"Whether it's suitable or not suitable [for certain people] is not a question," it said, meaning the company believes that everyone, regardless of age and health, can benefit from it.
The statement, however, is not entirely correct.
Chen Shih-yang (陳峙仰), chief of the gout center at Taipei's Country Hospital, advised gout sufferers to stay away from this kind of concentrated drink as the volume of purine in essence of clam is more than 100 times that contained in normal food and beverages.
"For healthy people who metabolize purine normally to form uric acid, it's OK to drink clam essence following the manufacturers' recommendations. But gout patients should stay away from these products," Chen said.
The Taiwan branch of Cerebos International Health Ltd, which distributes essence of chicken in the local market, also introduced its essence of clam to local consumers in June last year.
The company were more cautious than Taisugar in regard to health warnings, and had added a statement to the product packaging saying: "People allergic to seafood, pregnant women and those about to have surgery or with fresh wounds should consult professionals."
Some have criticized the manufacturers' failings in exposing possible hazards, saying they are only interested in making a profit. The businesses, however, reiterated that they have done their best to provide detailed nutritional information on their packaging, and that printing a warning for gout sufferers or people with liver complaints is not practicable until scientific proof is made available.
"What we don't know is whether the man who complained about deteriorating gout last month had an excess of essence of clam or whether his eating habits were to blame, as people with his condition naturally would have to pay more attention to the intake of protein and calorific capacity," said Charlene Chou (周湘琳), public relations supervisor at Cerebos.
She said the firm's products clearly show the ingredients for consumers' reference. For instance, a 60ml can of essence of clam contains 0.33g of protein, far lower than the maximum amount of 40g a seriously ill patient should take, she said.
"By following our recommendations, drinking one to two cans a day is OK. But some people might drink five cans a day thinking it will help them regain physical strength, which is beyond our recommendation," Chou said.
Since its essence of clam was launched last year, Cerebos has secured sales of over NT$100 million (US$3.03 million) as of last month, taking a 15 percent to 20 percent share of the market.
