Breast Milk And Guinness Beer: Any Connection?

For centuries, women have been told that drinking Guinness, a dark, Irish beer, can boost their breast milk production. The idea that beer increases lactation is not new, with records from as far back as 2000 BC showing that the Sumerian people prescribed beer to aid breastfeeding. While the barley in beer can boost prolactin, a hormone necessary for milk production, the alcohol in beer decreases milk production and inhibits the milk ejection reflex. So, while non-alcoholic beer may be a good option for breastfeeding mothers, drinking Guinness to increase breast milk production is probably not the best course of action.

The history of beer and breastfeeding

In the past, beer was full of grains and herbs thought to increase the flow of a mother's milk, known as galactagogues. Traditional beers were also lower in alcohol content and higher in nutritional value, which may have contributed to their perceived effectiveness in enhancing milk supply. The alcohol in beer was also believed to have a relaxing effect on nursing mothers, which may have indirectly supported lactation.

In the early 1900s, beer companies capitalized on this association and began marketing low-alcoholic beers or "tonics" specifically to lactating women, claiming that they would stimulate appetite, increase strength, and enhance milk yield. The marketing campaign for Guinness, in particular, emphasized its health benefits, including its high iron content. This helped solidify the drink's original slogan: "Guinness is good for you." Nursing mothers were encouraged to drink Guinness to boost their milk production.

However, despite the deep roots of this belief in history and across cultures, modern research suggests that alcohol interferes with the release of oxytocin, which affects the let-down of breast milk. Studies have shown that babies consume less milk after their mothers drink alcoholic beverages, and chronic alcohol use may lead to a decrease in overall milk supply.

While non-alcoholic beer, especially those rich in barley or hops, may have some lactogenic effects due to their ability to stimulate prolactin secretion, alcoholic beers are more likely to reduce milk supply if consumed regularly.

The science behind the myth

The idea that drinking Guinness beer increases breast milk has been around for centuries. As far back as 2000 B.C., records show that the Sumerian people prescribed beer as an aid for breastfeeding. Along with many other foods—like anise, fenugreek, and oatmeal—beer developed a reputation as a galactagogue, a food thought to stimulate lactation.

This reputation was bolstered by the early 1900s marketing campaign for Guinness, which positioned the beer as a "healthful" beverage due to its high iron content. Nursing mothers were encouraged to drink Guinness as a milk-boosting tonic.

While the claim that Guinness increases breast milk supply may have been overstated, there is some scientific truth to the idea that beer can boost breast milk production. Beer contains a polysaccharide, a type of carbohydrate present in barley hops, which has been linked to an increase in prolactin, the hormone that aids milk production.

However, the alcohol in beer can obscure these potential benefits. Studies have shown that when mothers consume alcohol and breastfeed, it can alter the flavor of their milk, causing infants to feed less. Additionally, alcohol inhibits the production of oxytocin, a hormone that triggers the "letdown" reflex, which is necessary for milk ejection. As a result, babies may consume less breast milk after their mothers have consumed alcohol.

So, while the belief that drinking Guinness increases breast milk supply may have some basis in the presence of galactagogues in beer, the overall effect of alcohol is more likely to suppress milk production and breastfeeding. Therefore, alcohol-free beers that contain barley may be a better option for boosting breast milk supply.

The best beers for breastfeeding

It's long been believed that beer can help breastfeeding mothers increase their milk supply. The idea has roots deep in history, with records showing that the Sumerian people prescribed beer as an aid for breastfeeding as far back as 2000 B.C.

Beer contains barley, which has a polysaccharide that stimulates the secretion of prolactin, the hormone necessary for milk production. However, it's important to note that alcohol, a component of beer, decreases milk production and inhibits the milk ejection reflex.

So, what's the verdict? According to experts, non-alcoholic beer is the best option for breastfeeding mothers. These beers provide the galactagogue (milk supply-enhancing) benefits of barley without the negative effects of alcohol.

• Erdinger Weissbier German Wheatbeer Non-Alcoholic Beer: This German beer is brewed in Bavaria, Germany, using a 110-year-old tradition. It's free of chemical additives and is brewed under strict purity laws using malt, water, hops, and yeast. It has less than 0.5% alcohol content.
• Beck's Non-Alcoholic Beer: This classic German beer has a distinctive full-bodied taste with a slightly fruity but firm crispness and a fresh 'hoppy' bouquet. It has 0.5% alcohol content and it's recommended to wait for at least 2 hours after drinking before breastfeeding or pumping.
• Guinness Stout/Guinness Draught: With an ABV of 4.3% and 4.2% respectively, these Irish beers have a lower alcohol content than most beers. It's recommended to drink only one bottle and wait for about 2 hours before breastfeeding or pumping.
• Karamalz Classic (Non-Alcoholic Malt Beverage): This German non-alcoholic malt beverage provides healthy carbohydrates, vitamins, minerals, and trace elements. It's made with pure water, hops, malt, and caramelized sugar, and is low in calories.
• Big Drop Chocolate Milk Stout: This beer has an alcohol content of less than 0.5% ABV, keeping the taste of beer intact. It has a lovely coffee-toasted taste and a malt nose, with a warmth uncommon to ordinary beers.

The effects of alcohol on breast milk

A long-standing belief

For centuries, beer has been used by breastfeeding mothers to increase milk production. This belief stems from the composition of beer, which has a high concentration of barley. Barley contains a polysaccharide that stimulates the secretion of prolactin, the hormone necessary for milk production.

The science behind it

While there is some truth to the idea that beer boosts breast milk, the amount of research on this topic is quite limited. Some studies have found a link between the polysaccharide in barley hops and an increase in prolactin. However, it is important to note that alcohol can decrease milk production and inhibit the milk ejection reflex, known as "let-down".

The impact on babies

According to research, nursing infants consumed approximately 20% less breast milk during the first four hours after their mothers consumed alcohol, even though they spent a similar amount of time on the breast. This reduction in milk intake can have negative effects on the baby, including increased REM sleep, decreased weight gain, and potential impairment of cognitive development.

Recommendations

The Centers for Disease Control and Prevention (CDC) recommends that the safest option while breastfeeding is to avoid consuming alcohol altogether. However, if a breastfeeding mother chooses to drink alcohol, it is important to drink in moderation and wait at least two hours after consuming one standard drink before breastfeeding or pumping.

Alternatives

Instead of alcoholic beer, breastfeeding mothers can opt for non-alcoholic beer, which provides the potential milk-boosting benefits of barley without the negative effects of alcohol. Maintaining a balanced diet and destressing can also help with milk production.

Advice for breastfeeding mothers

There is a long-held belief that drinking Guinness can increase breast milk supply. This idea has been passed down for centuries, with records from as far back as 2000 B.C. suggesting that beer was prescribed as a milk-boosting agent. However, it's important to separate fact from fiction.

The role of barley

The belief that beer increases breast milk supply is not entirely unfounded. Beer contains barley, which has a polysaccharide that stimulates the secretion of prolactin—the hormone necessary for milk production. However, it's important to note that alcohol, a component of regular beer, decreases milk production and inhibits the milk ejection reflex.

The verdict

So, what's the verdict on drinking Guinness to increase breast milk supply? While the barley in beer may provide some benefits, the presence of alcohol counteracts these benefits by suppressing milk production and inhibiting the milk ejection reflex. Therefore, drinking Guinness is not likely to be an effective solution for increasing breast milk supply.

Recommendations

If you are looking for ways to increase your breast milk supply, there are a few recommendations to consider:

• Consume galactagogues: Galactagogues are substances that can help increase milk supply. Examples include oatmeal, almonds, salmon, beans, and spinach.
• Drain your breasts frequently: Regularly emptying your breasts stimulates milk production.
• Get plenty of sleep and reduce stress: Adequate rest and stress reduction can positively impact milk production.
• Seek professional help: If you continue to experience low milk supply, consider consulting a healthcare professional or a lactation consultant. They can help identify the underlying cause and provide personalized advice.

Remember, while an occasional beer is generally considered safe for breastfeeding mothers, it's important to drink in moderation and ensure adequate time has passed before breastfeeding or pumping.
