Protein And Beer: Mixing, Myths, And Health

Drinking beer after consuming protein is a topic of debate, especially for fitness enthusiasts. While some advocate for the health benefits of beer, such as its nutrient content and stress reduction properties, others argue that alcohol can negatively impact muscle growth and recovery. The human body treats alcohol as a toxin, which can take precedence in metabolism, potentially hindering protein synthesis and fat-burning processes. Additionally, alcohol's diuretic nature can lead to dehydration, counteracting the rehydration needed after a workout. However, moderation is key, and an occasional beer after exercise may not significantly hinder progress, especially when paired with a balanced diet and adequate refuelling.

Can you drink beer after drinking protein?

Beer has nutrients like selenium, B vitamins, phosphorus, and niacin

Beer is often viewed as a source of empty calories, but it does contain some nutrients, including selenium, B vitamins, phosphorus, and niacin.

Selenium is an antioxidant that can help protect the body's cells from damage caused by free radicals and may provide other health benefits such as a reduced risk of certain types of cancer. B vitamins are essential water-soluble nutrients that play a crucial role in energy production, nervous system health, and the maintenance of red blood cells. Phosphorus is important for maintaining strong bones and teeth, while niacin, also known as vitamin B3, is important for energy metabolism and may have beneficial effects on cholesterol levels.

In addition to these nutrients, beer also contains other beneficial compounds such as protein, fiber, and silicon. The protein content in beer, although not as high as in dedicated protein sources, can still provide a good amount of this essential macronutrient. Fiber is important for digestive health and regular bowel movements, while silicon has been linked to the prevention of osteoporosis, helping to maintain strong bones.

While beer does contain these beneficial nutrients and compounds, it is important to remember that it is not a significant source of these compared to whole foods like fruits and vegetables. The positive effects of these nutrients can be outweighed by the negative consequences of excessive alcohol consumption, which can include an increased risk of weight gain, liver disease, depression, and certain types of cancer. Therefore, moderation is key when it comes to drinking beer, and it should not be relied upon as a primary source of nutrients.

Alcohol is considered a toxin by the body

While beer has been suggested as a post-workout drink, offering some nutritional benefits, it is important to remember that alcohol is considered a toxin by the body.

The human body treats alcohol as a toxin, and as a result, the process of metabolising it can take priority over other important functions, such as muscle-building and fat-burning. Professor Louise Burke, the Australian Institute of Sport's chief of nutrition strategy, explains that because our bodies view alcohol as a toxin, we need to process it as quickly as possible. This means that it takes over our metabolism and may interfere with other processes that we would like to occur post-exercise, such as protein synthesis and fat-burning.

Alcohol is a toxic substance that has been classified as a Group 1 carcinogen, the highest-risk group, by the International Agency for Research on Cancer. This classification puts it alongside asbestos, radiation, and tobacco. Alcohol is linked to an increased risk of developing at least seven types of cancer, including common types such as bowel cancer and female breast cancer. The carcinogenic effects of alcohol are caused by its breakdown in the body, specifically the production of the carcinogen acetaldehyde, which damages DNA. This damage to DNA can lead to the growth of cancer.

The negative impact of alcohol on the body's ability to repair and recover after a workout is further supported by a 2014 study published in PLOS One. This study found that consuming alcohol after a strenuous workout, even when paired with a protein shake, negatively impacted the body's repair process and adaptation to training.

In addition to interfering with muscle-building and fat-burning, alcohol consumption can also lead to dehydration, which is counterproductive after a workout when the body needs to replenish lost fluids. Alcohol's diuretic properties can promote dehydration, which is a particular concern with drinks that have higher concentrations of alcohol. Furthermore, alcohol consumption can impact cognitive function, leading to poor decisions, such as making unhealthy food choices that can undermine fitness and health goals.

While moderate consumption of beer or other alcoholic beverages may offer some nutritional benefits, it is important to remember that alcohol is considered a toxin by the body. The negative impact of alcohol on muscle-building, fat-burning, and the body's repair processes, coupled with its dehydrating effects and potential cognitive consequences, should be carefully considered when deciding whether to include alcoholic drinks in one's routine, especially after physical exercise.

Alcohol can slow down muscle growth and recovery

Additionally, alcohol is considered a toxin by the body, which prioritizes removing it as quickly as possible. This shift in metabolism can interfere with other important post-exercise processes, such as protein synthesis and fat burning. The body's focus on metabolizing alcohol can slow down the natural process of burning fat stores, leading to potential weight gain and a decrease in overall fitness levels.

Furthermore, alcohol negatively impacts sleep quality. Sleep is crucial for muscle recovery and tissue repair, and alcohol disrupts the body's restorative rapid eye movement (REM) sleep. This can result in daytime drowsiness, fatigue, and poor concentration, hindering the body's ability to recover optimally.

While moderate alcohol consumption may not have a significant impact on muscle growth and recovery, excessive drinking or binge drinking can lead to more severe negative consequences. For individuals focused on fitness goals, optimal nutrition, and overall health, reducing alcohol intake or choosing non-alcoholic alternatives is advisable.

Alcohol disturbs protein synthesis

Alcohol, or ethanol, is a chemical found in beer, wine, and liquor. It is not a macronutrient, but it does provide calories. When we consume alcohol, our body uses it as fuel before burning other energy sources. This can negatively impact fat-burning and muscle-building processes.

The human body treats alcohol as a toxin, and in the rush to get rid of it, muscle-building and fat-burning may be put on hold. Alcohol can also disrupt protein synthesis, which is how our muscles recover and grow. One study found that consuming alcohol after a workout negatively impacted the body's repair process and adaptation to training, even when consumed with a protein shake.

Alcohol can also affect the phosphorylation of mTOR, a protein that plays a crucial role in muscle protein synthesis. In addition, alcohol consumption can lead to increased levels of cortisol, a stress hormone that can interfere with testosterone production and muscle growth.

Overall, while moderate alcohol consumption may not completely derail your fitness goals, habitual consumption, especially in high amounts, will likely hinder muscle growth and recovery.

Beer has calories and should be consumed in moderation

Beer is often viewed as empty calories, but it does contain some vitamins and minerals. These include B vitamins, selenium, phosphorus, niacin, potassium, calcium, thiamine, iron, and zinc. Beer also contains a small amount of protein and fibre. However, it is important to note that the number of calories and carbohydrates in beer varies depending on the type and amount consumed. For example, a 12-ounce can of ale, lager, porter, premium beer, or stout typically has more than 12 grams of carbohydrates, while a light beer has only about one-fourth of that amount.

While drinking beer in moderation (no more than two drinks per day or 14 drinks per week for men, and no more than one drink per day or seven drinks per week for women) can be part of a healthy diet, excessive consumption can lead to various health risks. These risks include injuries, certain cancers, weight gain, liver disease, depression, and alcohol dependence. Additionally, as beer is a diuretic, consuming it after a workout can promote dehydration, which is not ideal when the body needs to replace lost fluids.

Furthermore, while beer has been linked to potential health benefits such as improved heart health, blood sugar control, stronger bones, and reduced dementia risk, these benefits are only associated with light to moderate intake. Heavy and binge drinking have been shown to counter these benefits and increase the risk of negative health consequences.

In conclusion, while beer does contain some calories and nutrients, it should be consumed in moderation as part of a balanced diet. Excessive consumption can lead to various health risks, and there are alternative whole food sources that can provide the same nutrients without the negative side effects.
