Guinness Beer: Carcinogen Concerns And Consumption

Alcoholic beverages have been classified as carcinogenic to humans, with the National Toxicology Program of the US Department of Health and Human Services listing consumption of alcoholic beverages as a known human carcinogen. Blogger Vani Hari, also known as the Food Babe, has investigated the ingredients of mainstream beers and found GMOs and carcinogens in a variety of popular beer beverages, including Guinness. While Guinness is known for its iconic taste and texture, it is important to examine the potential presence of carcinogens and their impact on health.

Guinness contains carcinogens, but so do other beers

Alcoholic beverages have been classified as carcinogenic to humans, and beer is no exception. A variety of carcinogenic compounds can be found in beer, and Guinness contains some of these, including ethanol and ethyl carbamate. However, it is important to note that the levels of these carcinogens in beer are typically low, and the risk of cancer increases with higher consumption. Other beers may also contain carcinogens, and the specific ingredients and processes used can vary between different beer manufacturers.

Guinness, with its iconic advertising campaigns, has long been associated with strength and health. While it does provide some nutritional benefits, such as antioxidants, B vitamins, and fibre, it is not significantly healthier than other beers. In fact, when it comes to calorie count, Guinness is only 15 calories more than Bud Light for a 12 oz pour. Additionally, the notion that Guinness is good for breastfeeding mothers is mostly a myth, as alcohol is not recommended for those who are nursing.

The link between alcohol consumption and cancer has been well-established. According to research, the more alcohol a person consumes, especially over an extended period, the higher their risk of developing an alcohol-associated cancer. This risk is further elevated for those who engage in binge drinking or combine alcohol with tobacco use. Moderate to heavy alcohol consumption has been linked to an increased risk of head and neck cancers, esophageal cancer, liver cancer, breast cancer, and colorectal cancer.

While Guinness and other beers may contain carcinogens, it is important to understand that the risk of cancer is associated with the amount consumed. Moderate consumption, defined as one drink per day for women and two drinks per day for men, is generally considered safe by health organizations. However, it is important to note that these guidelines do not encourage non-drinkers to start consuming alcohol, as the optimal number of drinks per day to minimise overall health risks is zero.

Carcinogenic compounds in alcoholic drinks include acetaldehyde, acrylamide, and arsenic

Alcoholic drinks have been classified as carcinogenic to humans by the International Agency for Research on Cancer (IARC) since 1988. Ethanol, the major constituent of alcoholic drinks, and its metabolite acetaldehyde were also classified as carcinogenic to humans in 2010. In addition to these two compounds, alcoholic drinks may contain other known or suspected carcinogens as constituents or contaminants. These include acrylamide, arsenic, and several other chemicals.

Acetaldehyde is a toxic chemical and a probable human carcinogen. It is a metabolite of ethanol, produced when the body breaks down alcohol. It can also be generated by microorganisms in the gastrointestinal tract or originate from salivary glands during alcohol consumption.

Acrylamide is a human carcinogen classified as Group 2A by the World Health Organization (WHO). It is often found in coffee products and is also present in some alcoholic drinks.

Arsenic is a known human carcinogen and is one of the contaminants that can be found in alcoholic beverages. It poses a potential risk to the drinker, although it is typically found in low concentrations.

The presence of these carcinogenic compounds in alcoholic drinks, including Guinness beer, underscores the importance of consuming such beverages in moderation or abstaining altogether to minimize health risks.

Alcohol is linked to a higher risk of mouth, pharynx, larynx, and oesophageal cancers

Alcohol is a known carcinogen, and drinking it is linked to a higher risk of several types of cancer. This includes cancers of the mouth, pharynx, larynx, and oesophagus. The evidence shows that the more alcohol a person consumes, the higher their risk of developing these cancers. Even light or moderate drinking can increase the risk, with heavy drinking significantly increasing the likelihood of developing these cancers.

The link between alcohol consumption and mouth, pharynx, larynx, and oesophageal cancers is well-established. Moderate drinkers have a significantly higher risk of oral cavity and pharynx cancers than non-drinkers, with heavy drinkers having an even higher risk. The risk of larynx cancer is also elevated for moderate and heavy drinkers. The combination of alcohol and tobacco use further increases the risk of these cancers, with a synergistic effect observed when alcohol and tobacco are used together.

Alcohol is metabolised by the body into acetaldehyde, a toxic chemical and probable human carcinogen. Acetaldehyde can damage DNA and proteins and is formed when ethanol is metabolised by enzymes such as alcohol dehydrogenase (ADH) and cytochrome P-450 2E1 (CYP2E1). CYP2E1 activity also produces reactive oxygen species (ROS), which can cause oxidative stress and further damage DNA.

In addition to the direct effects of alcohol on cancer risk, it can also impact the absorption of nutrients like folate, which is important for DNA methylation and synthesis. Alcohol can also increase oestrogen levels, which may be linked to an increased risk of certain cancers, such as breast cancer.

The mechanisms by which alcohol contributes to the development of mouth, pharynx, larynx, and oesophageal cancers are complex and interrelated. The damage caused by alcohol can lead to DNA changes, oxidative stress, and inflammation, all of which are factors in the development of these cancers. While the exact mechanisms are not fully understood, the evidence consistently shows a link between alcohol consumption and an increased risk of these cancers.

Beer is made with barley, a whole grain that provides some nutritional benefits

It is true that alcoholic beverages have been classified as carcinogenic to humans. A study by the National Cancer Institute found that the more alcohol a person drinks, the higher their risk of developing an alcohol-associated cancer. Even those who have no more than one drink per day have a modestly increased risk of some cancers.

However, beer is made with barley, a whole grain that provides some nutritional benefits. Barley is a good source of nutrients such as thiamine, riboflavin, niacin, vitamin B6, folate, iron, magnesium, phosphorus, potassium, zinc, copper, manganese, and selenium. It is also a source of beta-glucan, a type of fiber that has been linked to lower cholesterol and improved blood sugar control.

In addition to its fiber content, barley contains antioxidants such as vitamin E, beta-carotene, lutein, and zeaxanthin, which help protect against and repair cell damage caused by oxidative stress.

Studies have also shown that eating whole grains, such as barley, may reduce the risk of developing type 2 diabetes and obesity. A large study in over 360,000 people found that those with the highest consumption of whole grains had a 17% lower risk of death from all causes, including cancer and diabetes, compared to those with the lowest whole-grain intake.

While beer may contain carcinogens, it is important to note that the specific type of beer and the amount consumed can affect the level of risk. Additionally, the nutritional benefits of barley, a key ingredient in beer, can provide some health benefits when consumed in moderation.

Guinness is lower in calories than most popular lager beers

While Guinness is not a health drink, it does contain fewer calories than many other popular beers. A single 12-ounce serving of Guinness draught has 125 calories, which is fewer than Budweiser (145), Coors (147), Corona Extra (148), Heineken (142), and Sam Adams Boston Lager (175). Even when served in a 20-ounce pint glass, Guinness only has 210 calories. This is still lower than many other beers, such as premium lagers, which can contain as much as 160 calories per pint.

The reason for Guinness's lower calorie count compared to other beers may be due to its slightly lower alcohol content. Guinness has an alcohol by volume (ABV) of 4.1% to 4.3%, while other beers often have a higher ABV. Additionally, Guinness sources most of its calories from alcohol, with 78 out of 125 calories in a serving coming solely from alcohol.

It is worth noting that the number of calories in a beer depends on its alcohol levels and sugar or carbohydrate content. Alcohol has a more significant impact on the calorie count due to the higher number of calories per gram in alcohol compared to carbs. Therefore, while Guinness has fewer calories than many lager beers, it is not a "low-calorie" drink.

When it comes to health, it is important to remember that alcohol consumption has been linked to an increased risk of certain types of cancer. According to the National Toxicology Program of the US Department of Health and Human Services, alcohol consumption is listed as a known human carcinogen. The more alcohol a person drinks, especially over an extended period, the higher their risk of developing an alcohol-associated cancer.
