Gastric cancer asian
Since that time, new data have become available, these have been incorporated into the Monograph, and taken into consideration in the present evaluation. Exposure Data 1. Types and ethanol content of alcoholic beverages 1.
Types of alcoholic beverages The predominant types of commercially produced alcoholic beverages are beer, wine and spirits. Basic ingredients for beer are malted barley, water, hops and yeast.
Wheat may be used. Nearly all wine is produced from grapes, although wine can be also made from other fruits and berries.
Spirits are frequently produced from cereals e. Main beverage types i. In addition to commercialized products, in many developing countries different types of home- or locally produced alcoholic beverages such gastric cancer asian sorghum beer, palm wine or sugarcane spirits are consumed WHO, Home- or locally produced alcoholic beverages are produced through fermentation of seed, grains, fruit, vegetables or parts of palm trees, by a fairly simple production process.
Alcohol content differs according to the main beverage type and may also vary by country. However, lower or higher ethanol content in alcoholic beverages is also possible.

The ethanol content in beer can range from 2. There is a trend in recent years towards higher To calculate the amount of ethanol contained in a specific drink, the amount e. Chemical composition The main components of most alcoholic beverages are ethanol and water.
Services Reg. Volatile compounds include aliphatic carbonyl compounds, alcohols, monocarboxylic acids and their esters, nitrogen- and sulfur-containing compounds, hydrocarbons, terpenic compounds, and heterocyclic and aromatic compounds. Non-volatile extracts of alcoholic beverages comprise unfermented sugars, di- and tribasic carboxylic acids, colouring substances, tannic and polyphenolic substances and inorganic salts IARC, Occasionally, gastric cancer asian additives, that are not permitted for use in commercial production have gastric cancer asian identified in alcoholic beverages.
These include methanol, diethylene glycol used as sweetener and chloroacetic acid or its bromine analogue, sodium azide and salicylic acid, which are used as fungicides or gastric cancer asian Ough, Contaminants may also be present in alcoholic beverages. Contaminants are defined as substances that are not intentionally added but are present in alcoholic beverages due to production, manufacture, processing, preparation, treatment, packing, packaging, transport or holding, or as a result of environmental contamination.
Personal Habits and Indoor Combustions.
Contaminants and toxins gastric cancer asian in alcoholic beverages are nitrosamines, mycotoxins, ethyl carbamate, pesticides, thermal processing contaminants, benzene, and inorganic contaminants such as lead, cadmium, arsenic, copper, chromium, inorganic anions, and organometals IARC, In view of the potential carcinogenicity of acetaldehyde and its known toxic properties, recent studies attempted to estimate exposure to acetaldehyde from alcoholic beverages outside ethanol metabolism at known levels of alcohol exposure.
Trends in consumption of alcoholic beverages Volume, pattern and quality of consumed alcohol are included in the description of differential exposure to gastric cancer asian.
In —09, WHO gastric cancer asian the Global Survey on Alcohol and Health, collecting data on alcohol consumption, alcohol-related harm and policy responses from its Member States. Total adult per capita consumption gastric cancer asian litres of pure gastric cancer asian is defined as the total amount of alcohol consumed per person, taking into account recorded consumption i. Recorded adult per capita consumption is calculated from production, export and import data, or sales data.
Unrecorded consumption is computed from representative surveys, specific empirical investigations or expert opinion.
Overall, there is a wide variation in the volume of alcohol consumed across countries. As presented in Table 1. Apart from some countries in Africa and a few countries in other parts of the world, alcohol consumption in the other regions is generally lower. Table 1. Gastric cancer asian, men consume more alcohol than women.
This is reflected in the differences in the number of lifetime abstainers, past year abstainers and former drinkers Table 1. A former drinker is a person who did not consume any alcohol during the past como detectar papiloma en la boca. Generally, gastric cancer asian percentage of lifetime and past year abstainers is higher in women than in men.
The prevalence of lifetime, past-year abstainers, and former drinkers are calculated gastric cancer asian large representative surveys.
Alcohol consumption remains low in the Eastern Mediterranean Region. Cancer in Humans 2. Description of cohort studies 2.
Studies in the gastric cancer asian population Cohort studies are classified by the country in which gastric cancer asian study was conducted Table 2. Since the previous IARC Monograph IARC,data on the association between alcohol consumption and risk of cancer have been published from several cohorts, including updates of cohorts described previously Bongaerts et al.
Studies in special populations This group of studies is characterized by the assumption that the study subjects have a pattern of consumption of alcoholic beverages that is different from that of the general population, e.
