Definitions

  • the invention relates to a food composition according to the preamble of claim 1 and a method according to the preamble of claim 23 for the preparation of such a food composition.
  • the invention also relates to a method according to the preamble of claim 32 to reduce or remove the acetaldehyde contained in a foodstuff from the foodstuff, a composition according to the preamble of claim 33 , which is added to the foodstuff, and the use of compounds containing acetaldehyde according to the preamble of claim 35 to prepare the food composition.
  • the first metabolite of alcohol is acetaldehyde. It has been shown to be carcinogenic both to test animals and humans (Salaspuro, M. Crit Rev Clin Lab Sci (2003) 40: 183-208). Alcohol is evenly distributed in the liquid phase of the organs. Hence, after enjoying alcohol and as long as there is alcohol in the organs, the alcohol content in blood, saliva, gastric juice and the contents of the intestine is the same. In that case, the microbes in the digestive tract are capable of oxidizing the alcohol to acetaldehyde. As the aldehyde dehydrogenase enzyme of the liver removes the acetaldehyde thus generated, no alcohol can accumulate in the liver, where the metabolism of alcohol mainly takes place.
  • Asian heavy drinkers who have a familial low-activity modification of the aldehyde dehydrogenase-2 (ALDH2) enzyme, have both an increased risk of developing a cancer of the mouth, the pharynx and the digestive tract, and an increased acetaldehyde content of the saliva after consuming alcohol (Väkeväinen et al. (2000) Alcohol Clin Exp Res 24:873-877). Even more common is the ADH3*1 gene/allele (ADH1C at present), which predisposes the heavy drinkers, who have this gene, to the upper digestive tract cancers because of increased local acetaldehyde contents. (Visa journal J-P et al. Gut. 2004 June; 53(6):871-6.)
  • acetaldehyde is thus formed from alcohol as a consequence of the hepatic metabolism and, locally, in the digestive tract via microbial alcohol dehydrogenase and that of mucous membrane cells (Salaspuro et al, (1996) Ann Med 28:195-200).
  • ethanol 0.5 g/kg
  • high acetaldehyde contents of a microbial origin (18-143 ⁇ M) have been found in human saliva; in other words, acetaldehyde mainly builds up in saliva as an intermediate product of the microbial metabolism; in addition, it is also produced by the mucous membrane cells and salivary glands (Homann et al, Carcinogenesis (1997) 18:1739-1743).
  • acetaldehyde also builds up in the stomach in the case, where the stomach is free from acid or has been made acid-free by medication (Väkeväinen et al, (2000) Alimentary Pharmacology Ther 14:1511-1518). It has also been shown that acetaldehyde builds up in the large intestine, as its bacteria that represent the normal flora are capable of converting ethanol into acetaldehyde (Jokelainen et al, (1996) Gut 39:100- 104).
  • endogenous ethanol can also be found, i.e. ethanol that is formed in the intestines in oxygen-free conditions under the effect of microbes. Acetaldehyde is formed, when this ethanol comes into contact with oxygen near the mucous membrane, for example.
  • microbes For atrophic gastritis patients, microbes produce high acetaldehyde contents from ethanol in the stomach, possibly leading to an enhanced gastric cancer risk among atrophic gastritis patients (Väkeväinen et al, Scand J Gastroenterol 2002 (6):648-655).
  • Acetaldehyde is formed in the mouth, the pharynx and the upper respiratory ducts also as a consequence of smoking and exposure to air contamination (passive smoking, fumes, exhaust gases, etc.). It has been proven that chronic smoking increases the acetaldehyde production of a microbial origin in saliva. Salaspuro et al. (2004) Int J Cancer, 2004 Sep. 10; 111(4):480-3) have proven that the average in vivo acetaldehyde concentration in saliva is about two times higher for smokers than for non-smokers after enjoying ethanol, the control time being 160 minutes.
  • the in vivo acetaldehyde in saliva was increased to ten-fold from the level it was after enjoying ethanol only.
