If taken continuously, the foodstuff has prophylactic and/or curative effects and is therefore suitable for the prevention and/or cure of civilisation-induced diseases, especially cardiovascular diseases and cancer. It is preferably provided in the form of a drink based on fruit and/or vegetable juice preferably containing eicosapentaenoic acid and/or docosahexaenoic acid or their esters as the omega-3-fatty acid. The vitamin component is preferably made up of beta-carotene, vitamin C and vitamin E. The fatty and fat-soluble components are preferably used in the form of a dry powder in making the foodstuff. The foodstuff is distinguished by its agreeable flavour, pleasant odour, attractive appearance and good shelf life and its effects and the aforementioned qualities therefor remain unchanged even after several months' storage.
