Beer is one of the most popular alcoholic beverages worldwide, but few people stop to consider what they’re really consuming—especially when it comes in a can. While the convenience of canned beer may be appealing, the dangers lurking inside go far beyond the alcohol content. The lining of most beer cans is coated with bisphenol A (BPA), a toxic chemical known to disrupt hormones and increase the risk of various diseases. Worse yet, most commercial beers are loaded with glyphosate, a harmful herbicide that has been linked to cancer and other chronic health conditions. If you enjoy an occasional beer, it’s crucial to know the risks and choose safer options.
BPA-Lined Cans: A Hormonal Hazard
Beer cans are lined with BPA-based epoxy to prevent the metal from corroding and affecting the taste of the beverage. However, BPA is a well-documented endocrine disruptor that mimics estrogen in the body, potentially leading to reproductive issues, hormone imbalances, and increased cancer risk. Studies have shown that even low levels of BPA exposure can contribute to infertility, metabolic disorders, and immune dysfunction. When beer sits in a can for extended periods, BPA can leach into the liquid, exposing consumers to harmful amounts with every sip. This risk is heightened when the can is stored in warm environments or subjected to temperature fluctuations, as heat accelerates the release of BPA.
Leaching
Beer possesses a natural acidity, with a pH level generally falling between 4.0 and 5.0. This acidic characteristic can promote the leaching of metals from its storage container. When beer is kept in aluminum cans, the acidity gradually deteriorates the thin protective coating within the can, resulting in aluminum leaching into the beverage. Exposure to aluminum has been associated with various health issues, such as neurological disorders, cognitive decline, and an elevated risk of Alzheimer’s disease. Regular consumption of beer from aluminum cans may lead to a gradual accumulation of aluminum in the body, potentially disrupting cellular functions and contributing to long-term toxicity. The interplay of acidity and aluminum exposure presents a possible concealed health risk when consuming beer from cans.
Glyphosate: A Toxic Ingredient in Most Beers
Even if you choose beer from a bottle to avoid BPA exposure, you may still be ingesting a dangerous toxin—glyphosate. Glyphosate is the active ingredient in Monsanto’s Roundup, the most widely used herbicide in the world. Unfortunately, glyphosate has made its way into the food and beverage supply, including beer. A study conducted by the U.S. Public Interest Research Group (PIRG) found that 19 out of 20 popular beers contained measurable levels of glyphosate. Since glyphosate is heavily used on grains like barley and wheat, which are primary ingredients in beer, contamination is nearly unavoidable in conventional brewing processes.
The Health Risks of Glyphosate in Beer
Glyphosate has been classified as a “probable human carcinogen” by the International Agency for Research on Cancer (IARC). Chronic exposure to glyphosate has been linked to an increased risk of non-Hodgkin’s lymphoma, liver damage, and endocrine disruption. Consuming even small amounts of glyphosate over time can also contribute to gut dysbiosis, leading to inflammation and compromised immunity. Since beer is often consumed regularly by many people, the cumulative exposure to glyphosate through beer consumption could pose a significant long-term health risk.
Bottles Aren’t Perfect, But They’re Safer Than Cans
When it comes to choosing between cans and bottles, glass bottles are the lesser evil. Glass is inert and does not leach harmful chemicals into the beer, making it a safer vessel for beverages. However, the glyphosate contamination remains an issue regardless of packaging. The only way to reduce your exposure to harmful chemicals in beer is to opt for organic, glyphosate-free options that are brewed using clean, non-GMO ingredients. Choosing bottled beer from brands that are transparent about their sourcing and production methods is a safer bet for your health.
The Healthiest Beers to Choose
If you’re looking for safer alternatives, organic beers are your best option. Organic beers are brewed with grains that are grown without the use of synthetic pesticides, herbicides, or GMOs, which eliminates the risk of glyphosate contamination. Some of the best organic beer brands include:
• Samuel Smith’s Organic Lager (UK): Made from certified organic malted barley and hops.
• Bison Organic Beer (USA): A leader in organic brewing with a commitment to sustainable practices.
• Peak Organic Brewing Company (USA): Known for its wide range of organic, craft-brewed beers.
German and Belgian Beers: A Safer Choice
Another safer option is choosing beers brewed in Germany and Belgium, where strict purity laws (such as the German Reinheitsgebot) mandate that only water, malt, hops, and yeast can be used in brewing. These regulations drastically reduce the likelihood of harmful additives and pesticide contamination. Beers such as Weihenstephaner, Ayinger, and Duvel offer a safer alternative for those looking to enjoy beer without the toxic load.
If you’re going to indulge in an occasional beer, it’s essential to make informed choices to protect your health. Avoid drinking beer from cans to prevent BPA exposure and opt for organic or European brands that are less likely to contain glyphosate and other harmful additives.
