Beer culture

Overview:

Beer production has a history of 5000 years, at present in the world per capita beer 22 l, 160 l the Czech relaoteblic, Germany, Britain and the United States developed countries 80 l. Since reform and opening up in China, the annual outlaotet has been increased by 20 55 times, is expected by the end of 2004 to 24.5 million litres. But the amount per capita is 17.5 L, below the world average.

 Second, the basic ingredients of beer (in 1 l beer) :

(a) carbohydrates:

1, 50 grams of carbohydrate substances (such as glucose, maltose, malt trisaccharide, etc.); 2, 3.5 grams of protein and its hydrolysate (e.g., peptide, amino acids), the proportion of carbohydrates and proteins in beer about 15:1, the most accord with human body balanced; 3, 35 grams of ethanol, drinks alcohol content in liquor is the lowest one kind of alcoholic beverages, moderation can help ward off cardiovascular disease, especially can be washed in the blood vessels of the formation of blood clots; 4, 50 g of CO2 and CO2 can help people gastric bowel movement, also is good for the body to quench.

(2) of the inorganic ions in beer: 1, 20 milligrams of sodium, beer for the low sodium drink, will not lead to high blood pressure because of the high sodium; 2, 80-100 mg of potassium, sodium and potassium ratio of 1-5, the proportion was the most help to keep the balance of osmotic pressure inside and outside the cell, but also to quench thirst diuresis; 3, 40 mg calcium, calcium is human body bone growth and development necessary ingredients; 4, 100 mg magnesium, magnesium is one of the important auxiliary enzyme action in the system of human body metabolization substance; 5, 0.2 0.4 mg/zinc, zinc and enzyme action in the system of human body metabolization important auxiliary material, zinc ions in the beer and complexing state, is conducive to the absorption of human body. 1 liter of beer in the zinc magnesium ions enough human daily requirement; 6, silicon 50-150 mg, a certain amount of silicon is beneficial to keep bones healthy, modern people is very pay attention to the intake of silicon, some mineral water because of containing metasilicate and loved by the people; 7, phosphorus, phosphorus is human body cell growth essential ions, the 1 liter of beer of phosphorus content enough to meet the nutritional needs of the human body a day; 8, PH 4.1 to 4.4, beer slightly acidic helps regulate the body's acid-base balance.

(3) of the vitamins in beer: 1, 0.15 mg, vitamin B10.1 - B20.5-0.13 mg, B60.5-1.5 mg, H0.02 mg; 2, niacinamide 5-20 mg, 0.5 1.2 mg pantothenic acid, choline, 100-200 mg; 3, 0.1 to 0.2 mg of folic acid, folic acid in beer helps reduce cysteine content in blood of human body, and the high cysteine content in the blood can cause heart disease.

(4) the anti-aging substances in beer: modern medical research proof: metabolites in the body - super oxygen ions and the accumulation of oxygen free radicals, can cause the human cardiovascular disease, cancer and accelerated aging. The antioxidant compounds in beer - from malt hop polyphenols and flavonoids, formed in the process of brewing reduction of ketones, melanoidin and yeast secretory glutathione etc., is one of the best reducing agents reduce oxygen free radicals. Especially the polyphenols in phenolic acid, vanillic acid and ferulic acid, can avoid the beneficial to human body low density lipid (LDL) oxidation, prevent cardiovascular disease. Glutathione has an active hydrophobic, can eliminate oxygen free radicals of mankind, is an effective material for human anti-aging. Yeast can secrete glutathione normally 10 to 15 mg/l, some new development of anti-aging beer yeast glutathione production can be as high as 35-56 mg, it is very beneficial to human body health.

Three, possible harmful substances in beer misunderstanding: 60 s, as a result of the limitation of production conditions, some materials processing method is undeserved, leading to contain carcinogenic nitrosamines and aflatoxin in beer. After 80 s, with the improvement of production technology, no longer exists the substances in beer. "Beer belly" is the problem that some fear, in fact, the main reason is because when drinking beer at the same time, the cause of the high fat, high protein intake.

Experts initiative: the nutrition, anti-aging substance concentration in beer is fresh beer, drink fresh beer is the most healthy!
