For Melody Fong, chlorella, a fresh water algae, is something she must take every day. Available in pill form, Melody says it gets rid of toxins from your body and anyone can take it. 'We are all exposed to pollution from the air, from pesticides in foods, additives and preservatives,' she says. 'Chlorella detoxifies the body.' So health-conscious is Melody that she has opened her own health food shop in Central called Nutrihealth Centre which, apart from chlorella, also sells dietary supplements, vitamins and herbal supplements. 'I have always been sports orientated and believe that eating the right foods and having a healthy lifestyle will give you optimum health,' says 28-year-old Melody who competes in triathlons and climbs rocks. 'If there is one thing people here need to do more it is exercise. It would make them feel less stress.' A picture of health herself, Melody does not eat much red meat. She prefers lots of vegetables, fish and chicken but enjoys a glass of wine occasionally.
