is considered a toxic metal, competing with iron, copper, zinc, manganese and selenium for ligands in biological systems, and is one of the most effective elements capable of decreasing intestinal absorption of iron in the human body. Once absorbed, it accumulates in the kidneys, having a mean life of 1830 years. Concentrations of cadmium ion greater than 200 ig g damage the kidney irreversibly. Cadmium is found in many foods, especially in cereals and seafood, but cocoa appears to be high in...

Biological or Psychological Phenomenon David Benton Chocolate is a uniquely attractive substance that has an appeal unmatched by any other food item. Large sections of the population will readily admit to craving chocolate some will even claim to be addicted 1 , although this is lay self-diagnosis rather than an accurate or medically justifiable description. Articles in the media and popular books have speculated that chocolate's appeal can be explained in terms of the influence that it has on...

Those who crave chocolate tend to do so when they are emotionally distressed. A second consideration is whether feelings of guilt are associated with the consumption of chocolate. There are two major explanations of chocolate craving. First, it results from a pleasant taste. Second, it reflects physiological mechanisms. It has been suggested that these may include increased serotonin production, the release of endorphins, the actions of methylxanthines, phenylethylamine and the supply of...

materials have protective effects against many of these diseases. At the same time, it has become increasingly appreciated that certain constituents in plants have antioxidant properties. It is therefore not surprising that there is a widespread presumption that at least some of the protective effects of plants depend upon these antioxidant compounds. It may be speculated that plant materials that are rich in antioxidants are also beneficial to human health. However, various pieces in this...

Early writers such as Morris 6 identified two broad botanical groups Criollo and Forastero in the species T. cacao which are still valid today. Later another group was added 7 , which is a cross between the other two and is called Trinitario. The characteristics of these groups are shown in Table 2.2 and in Fig. 2.3. The Criollo types ferment quickly and in earlier times were considered to have a highly regarded, but usually weak, chocolate flavour. These types were probably domesticated by the...

However, the physiological effects from theobromine are generally weak to moderate in strength. In addition, the physiological effects of the methylxanthines are greatly reduced when consumed as constituents of cocoa products compared to pure compounds or solutions 25 . The difference is partially attributed to reduced gastrointestinal absorption of methylxanthines due to the polyphenol or fat content. As a result of these factors, consumption of cocoa and chocolate foods does not result in any...

The main phytochemicals are listed in Tables 8.1, 8.2 and 8.3, together with estimates of concentration where available. A problem with the published information is that starting materials may vary between unfermented beans, fermented beans, beans or cocoa mass after roasting, and, in rare instances, cocoa powder or chocolate....
