Many people turn to a pint of beer after a busy day at work to unwind and blow off steam, but little do they realise that they might be making their brain healthier in the process. According to scientists, a pint of beer has a host of health benefits to offer - apparently, it has brain-boosting vitamin B6, providing about 15 per cent of your daily requirement. Most of the ingredients used in beer are barley, yeast, and wheat, and these ingredients are sources of vitamin B6. However, just because of some benefits, one must not go on a mindless drinking spree.Is beer good for your brain?The study, published in the Journal of Agricultural and Food Chemistry, found some health benefits of beer that deserve recognition and credit, but it did not completely overlook the drawbacks. In fact, the drawbacks outweigh the benefits of drinking beer - beer belly and high blood pressure, for instance. In this study, however, researchers dug deeper into the potential benefits of drinking beer. Some of the key benefits of drinking beer are:Healthy immune systemGood for the brainHelps obtain energy from carbohydrates and proteins in foodHelps the body make haemoglobinWhat are the dietary sources of vitamin B6?Vitamin B6 is found in some foods, and in supermarkets, you can also buy foods fortified with vitamin B6. Some of the best dietary sources of vitamin B6 are:TurkeyPorkChickenSome types of fishBananasMilkOatsPeanutsWhich type of beer has high vitamin B6 levels?The study found that bock beer has the highest levels of vitamin B6 because of its high alcohol content. Following this are wheat beer and other dark beers. Non-alcoholic beers, on the other hand, have ethanol removed after full fermentation and provide higher vitamin B6 levels than those that are made with yeasts that produce less ethanol.How much vitamin B6 do you need in a day?Researchers noted that men need about 1.4 mg of vitamin B6 per day and women need 1.2 mg. An average lager can provide 20 per cent of the daily requirement, while a non-alcoholic version can provide about 59 per cent. The research further found that one litre of beer can contain 0.3 to 1 mg of vitamin B6. The study findings, therefore, are only beneficial for people looking to optimise their vitamin B6 intake. Researchers also said that because vitamin B6 is found in abundance in food sources, there is almost no need for one to turn to beer for this purpose.Especially for people dealing with certain health issues, such as chronic kidney disease or alcoholism, beer must not be relied upon to increase vitamin intake. Instead, it is important to focus on other sources of B vitamins like B12 or B2, which are found in abundance in animal foods and dairy products. These foods can also help you absorb energy better from food and play a role in metabolism. People who are vegan can opt for other fortified substitutes to meet their nutritional requirements.
