The composition and dental properties of eight different soft drinks, representing some of the most popular types used in the UK, were examined. Demineralization experiments were conducted on hydroxylapatite, the basic component of dental enamel, determining calcium dissolving by atomic absorption spectroscopy and phosphorus by u.v. visual spectrophotometry. The titratable acid content of the d...

BACKGROUND Intake of free sugars in the population exceeds recommendations, with the largest source in the diet being sugar-sweetened beverages (SSBs). SSB consumption is linked to adverse health consequences and contributes to health inequalities, given greater consumption amongst the most deprived. One possible intervention is to reduce the available sizes of SSB packaging but there is an abs...

UNLABELLED Iron has been suggested to reduce the erosive potential of cola drinks in vitro. OBJECTIVE The aim of this study was to evaluate in situ the effect of ferrous sulfate supplementation on the inhibition of the erosion caused by a cola drink. MATERIAL AND METHODS Ten adult volunteers participated in a crossover protocol conducted in two phases of 5 days, separated by a washout perio...

AIM Using scanning electron and light microscopy, this study qualitatively evaluated the erosive potential of carbonated cola beverages as well as sports and high-energy drinks on enamel surface substrate. METHODS AND MATERIALS Beverages used in this study included: Coca Cola Classic, Diet Coke, Gatorade sports drink, Red Bull high-energy drink, and tap water (control). Extracted human perman...

Caffeine is one of the main substances inculpated in the production of soft drinks. A variety of compounds are also used to preserve soft drinks; benzoic acid happens to be one of the preservatives. Caffeine and benzoic acid were isolated from four selected soft drinks – Coca Cola, Pepsi Cola, Mirinda and Fanta cocktail – using methylene chloride. For caffeine, the average absorbance obtained w...

The consumption of soft drinks has increased considerably during the last decades. Among them, the cola-based preparations are possibly the refreshments with the largest sales worldwide. During the previous years, important concerns have been raised about the effects of colas on human health. In this review, we introduce the cola effects on reproduction including pregnancy miscarriages, ovulato...

W investigate the impact of rivals’ product innovation and new advertising on a firm’s financial market value in mature product markets. Our test bed is the carbonated soft drink market between 1999 and 2003, a period characterized by a near duopoly between Coca-Cola and Pespi. Empirically, we focus on new product announcements as a proxy of product innovation and on filed trademarks as a measu...
