Carotenoids have been shown to have beneficial health effects such as pro-vitamin A activity, immune response modulation and anti carcinogenic activity. People consuming diets rich in carotenoids from natural foods, such as fruits and vegetables, are healthier and have lower mortality from a number of chronic illnesses. (cite: Functional food science and defence against reactive oxidative species, British Journal of Nutrition 1998, 80, Suppl. 1, S77–S112). Fucoxanthin is a major marine carotenoid found in edible seaweeds such as Undaria pinnatifida, commonly known as Wakame. Fucoxanthin also has anti-carcinogenic effects, apoptotic effects in cancer cells, anti-inflammatory effects and radical scavenging activity.
