Dark Beer And Breast Milk: Does Drinking Help Or Hinder?

Drinking dark beer to increase milk supply is a common recommendation in mom groups on Facebook. While the idea of drinking beer to boost milk supply sounds too good to be true, there may be some science behind it. The grains used to make dark or stout beers like Guinness contain phytoestrogens and a polysaccharide that can increase prolactin, the hormone responsible for lactation. However, the alcohol in beer can decrease milk production and inhibit the milk ejection reflex. So, does drinking dark beer actually increase milk supply? The scientific evidence supporting this claim is inconclusive, with some studies showing a potential boost in milk supply while others showing a decrease.

The barley in dark beer can boost prolactin production

However, it is important to note that the alcohol in beer may negatively impact milk production. Alcohol inhibits the milk ejection reflex, which can lead to a reduced amount of milk for the baby. Additionally, excessive alcohol consumption can affect a baby's sleep patterns and growth/development. Therefore, it is generally recommended to avoid alcohol consumption during the early stages of breastfeeding.

If you are looking to increase your milk supply, there are other ways to do so. Adequate hydration is essential, so drinking plenty of fluids, including water, is important. A well-balanced diet rich in whole unprocessed grains, fruits, and vegetables is also beneficial for overall health and milk production. Including galactagogues, such as oatmeal, fenugreek, and fennel, in your diet may also support lactation. Lastly, getting enough rest and practicing self-care can positively impact your milk supply.

Alcohol in beer can reduce milk supply

While some people believe that drinking beer can boost lactation, the scientific evidence supporting this claim is inconclusive. Studies examining the effect of beer on milk production and milk supply have yielded conflicting results.

The belief that beer increases milk supply may be due to the idea that ingredients used in brewing dark beers or "stout" beers like Guinness contain phytoestrogens. The grains used to make stout beer also contain a polysaccharide that is known to increase prolactin, a hormone associated with lactation. However, the alcohol component of beer decreases milk production and inhibits the milk ejection reflex, resulting in the baby receiving less milk.

The alcohol in beer has a diuretic effect, increasing urine output and fluid loss, which can lead to dehydration and a subsequent drop in milk supply. Additionally, chronic alcohol use is associated with early weaning and can impact the baby's sleeping schedule. Therefore, it is important for breastfeeding mothers to be cautious and consult with healthcare professionals before consuming alcohol.

Non-alcoholic beer can be a better alternative for breastfeeding mothers as it provides the potential milk supply-enhancing benefits of barley without the negative effects of alcohol.

Drinking non-alcoholic beer can be a good way to get the benefits of barley without the negative effects of alcohol

While the research is inconclusive, it is believed that the grains used in brewing dark beers contain a polysaccharide that increases prolactin, a hormone associated with lactation. However, the alcohol in beer may negatively impact milk production and inhibit the milk ejection reflex.

Non-alcoholic beer provides the benefits of hops and barley without the alcohol. It is a good way to get the potential benefits of barley without the negative effects of alcohol on milk production.

The yeast in beer is believed to be a natural galactagogue

The yeast in beer, especially dark beer, is believed to be a natural galactagogue or, in other words, a substance that increases milk production. This belief has persisted for decades, with records showing that beer has been prescribed as a milk-boosting agent as far back as 2000 BC.

The idea that yeast increases milk supply may be due to the presence of phytoestrogens in the grains used to make stout beer. Phytoestrogens are plant compounds that resemble the female hormone estrogen and have been historically used to help women increase their milk supply. Additionally, beer contains a polysaccharide derived from barley, which is known to increase prolactin, a hormone associated with lactation.

However, it is important to note that the scientific evidence supporting the claim that beer increases milk supply is inconclusive. Studies examining the connection between phytoestrogens and milk production have yielded inconsistent findings, and there is a lack of systematic studies evaluating the clinical effects of beer on lactogenesis.

Furthermore, while the barley in beer may have potential milk supply-enhancing benefits, the alcohol component of beer can decrease milk production and inhibit the milk ejection reflex, leading to reduced milk intake by infants. As such, non-alcoholic beer may be a better option for mothers looking to boost their milk supply, as it provides the potential benefits of barley without the negative effects of alcohol.

In conclusion, while the yeast in beer is believed to be a natural galactagogue, the scientific evidence supporting this claim is limited, and the potential benefits of beer consumption for increasing milk supply should be weighed against the potential negative effects of alcohol on milk production and infant health.

Studies on the effects of beer on milk production have yielded conflicting results

The belief that beer, especially dark beer, increases milk supply may stem from the idea that ingredients used in brewing dark beers or “stout” beers like Guinness, contain phytoestrogens. The grains used to make stout beer also contain a polysaccharide that is known to increase prolactin, a hormone associated with lactation. Phytoestrogens are plant compounds that resemble the female hormone estrogen and have been suggested to impact lactation and have even been used historically to help women increase milk supply.

However, studies examining the connection between these phytoestrogens and milk production have not provided consistent findings. While beer may contain certain components that could potentially positively influence milk production, such as barley or hops, the alcohol in beer may negatively impact human milk production, depending on the amount consumed.

Research has shown that not only does alcohol not stimulate milk production, but it may actually inhibit the let-down reflex and reduce the amount of milk the baby receives. According to a 2001 study, babies consumed approximately 20% less breast milk during the first 4 hours after alcohol had been consumed, despite spending a similar amount of time on the breast.

On the other hand, there are clear indications that beer can stimulate prolactin secretion, which may enhance lactogenesis in non-lactating humans and experimental animals. The component in beer responsible for the effect on prolactin secretion is not the alcohol content but a polysaccharide from barley, which explains why non-alcoholic beer has the same effect.

While the belief that beer increases milk supply persists, the scientific evidence supporting this claim is lacking.
