What You'll Learn
Coffee may help protect muscles as you age
Coffee may help protect your muscles as you age, according to a few recent studies. Researchers found that coffee drinkers had a higher muscle mass than non-coffee drinkers. The study, published in Frontiers in Nutrition, suggests that drinking coffee may help prevent sarcopenia, a musculoskeletal disease that compromises strength, muscle mass, and performance in the process of aging. People who drank coffee every day had an 11%-13% higher muscle mass, while decaffeinated coffee showed no significant association.
However, this association didn't hold true for everyone in the study. The relationship between coffee consumption and higher muscle mass disappeared in people with a body mass index (BMI) over 30. Additionally, the study didn't explain why coffee consumption may be associated with higher muscle mass. Experts stressed that while there is an association between coffee consumption and higher muscle mass, there is no evidence suggesting that coffee definitely improves muscle mass.
One theory suggests that coffee may help maintain autophagy, a process that helps "recycle" aging cells. Coffee contains multiple anti-inflammatory compounds, and it is known that inflammation is associated with decreased muscle mass. If drinking coffee can lower inflammation in the body, it can also lower "catabolic pathways," which happen when the body "eats its own muscle."
The benefits of coffee don't stop with muscles. Research suggests coffee may also protect against type 2 diabetes, cancer, and dementia. Coffee drinkers tend to have a more diverse range of microbes living in their guts, which may be because coffee is high in fibre, containing around 1.5g per cup. The polyphenols in coffee are also thought to support gut health.

Coffee may prevent sarcopenia, a muscle-wasting disease
Coffee consumption has been linked to higher muscle mass in older adults, according to recent studies. This is particularly significant in preventing or slowing the progression of sarcopenia, a muscle-wasting disease characterized by the age-related loss of muscle mass and strength. Sarcopenia affects mobility, frailty, and independence in older individuals and is associated with adverse health outcomes such as metabolic diseases, falls, fractures, and increased mortality.
While the exact mechanism is not yet fully understood, coffee's anti-inflammatory and antioxidant properties are believed to play a crucial role in mitigating the effects of sarcopenia. Coffee contains multiple anti-inflammatory compounds, and inflammation is known to contribute to decreased muscle mass through catabolic pathways, where the body breaks down its own muscle tissue. By reducing inflammation, coffee may help suppress these catabolic pathways and preserve muscle mass.
Additionally, coffee has been shown to induce autophagy, a process that recycles aging cells, further contributing to muscle health. The relationship between coffee consumption and muscle mass appears to be dose-dependent, with increased coffee intake correlating with higher muscle mass. However, this association was not observed in individuals with a body mass index (BMI) over 30.
It is worth noting that while coffee consumption may be beneficial for muscle health, it is not a standalone solution for preventing or treating sarcopenia. Physical exercise and nutritional supplementation remain the core management strategies, and further research is needed to fully understand the role of coffee in muscle health and determine the optimal amount of coffee intake to maximize potential benefits.
In conclusion, while more research is required, current evidence suggests that coffee may play a protective role against sarcopenia by maintaining healthy muscle mass as individuals age. This discovery could have significant implications for improving the quality of life and health outcomes in older adults susceptible to this muscle-wasting disease.

Coffee drinkers tend to have a more diverse range of gut microbes
Coffee consumption has been linked to muscle health in several ways. Some studies suggest that drinking coffee may be associated with higher muscle mass as one ages. Coffee contains anti-inflammatory compounds, and inflammation is associated with decreased muscle mass. Coffee may also help maintain autophagy, a process that helps recycle ageing cells. However, the relationship between coffee consumption and muscle mass is not conclusive, and more research is needed to understand the exact nature of this association.
Turning to the impact of coffee on the gut microbiome, recent studies have found a strong link between coffee consumption and the presence of certain microbes in the gut. Coffee drinkers tend to have a more diverse range of gut microbes, specifically, a higher prevalence of Lawsonibacter asaccharolyticus, a specific strain of bacteria. This microbe was 6 to 8 times more abundant in coffee drinkers than in non-coffee drinkers, and its presence was positively correlated with the amount of coffee consumed. The study, which analysed data from over 22,000 people, also found that coffee drinkers had higher levels of hippurate, a marker of metabolic and gut health.
The link between coffee consumption and the gut microbiome was observed across multiple cohorts from different countries and cultural backgrounds, making it less likely that the association is due to other dietary or lifestyle factors. Coffee is widely consumed worldwide, and its drinkers tend to accurately report their consumption, making it a useful variable for studying the gut microbiome. The study also found that coffee-related compounds, such as quinic acid, were present at higher levels in the blood of coffee drinkers carrying L. asaccharolyticus.
The gut microbiome is incredibly complex, consisting of trillions of microorganisms, including bacteria, viruses, and fungi. The interplay between specific foods and the microbial community structure in the gut is still not fully understood. However, the study suggests that the presence of chlorogenic acid, a polyphenol found in coffee, may stimulate the growth of L. asaccharolyticus. This was supported by in vitro experiments, which showed that coffee stimulated the growth of this bacteria.

Coffee may lower inflammation in the body
Coffee may not be the first drink that comes to mind when considering ways to improve muscle health, but recent studies have suggested that it may have a positive impact in this area. While the evidence is not yet conclusive, research indicates that coffee consumption may be linked to higher muscle mass, particularly as we age. This is significant because maintaining healthy muscle mass can reduce the likelihood of falls and injuries in older adults, keeping them mobile for longer.
One study, which examined the association between coffee consumption and low muscle mass prevalence, found that compared to those who drank less than one cup of coffee per week, the odds of low muscle mass prevalence decreased as coffee consumption increased. Specifically, the multivariable-adjusted odds ratio for low muscle mass prevalence was 0.62 for 1-3 cups of coffee per week, 0.53 for 4-6 cups per week or 1 cup per day, and 0.28 for 2 or more cups per day.
Another study, which looked at data on coffee intake and muscle mass among over 8,000 US adults, found that those who consumed at least two mugs of coffee per day had around a tenth more muscle mass compared to those who drank none. This effect is attributed to a potential reduction in frailty and improved muscle strength and metabolic health, which could also reduce the tendency towards type 2 diabetes. However, it is important to note that this study did not prove that coffee directly causes higher muscle mass, and larger studies are needed to confirm the link.
So, how does coffee affect muscle mass? One theory is that coffee contains anti-inflammatory compounds, and inflammation is associated with decreased muscle mass. By lowering inflammation in the body, coffee can also reduce "catabolic pathways," where the body breaks down its own muscle tissue. Additionally, coffee may help maintain autophagy, a process that recycles aging cells, which is vital for muscle maintenance.
While the exact mechanism remains unclear, the studies consistently show an association between coffee consumption and higher muscle mass. However, it is worth noting that the relationship between coffee consumption and muscle mass disappeared in individuals with a body mass index (BMI) over 30. As with any dietary choice, it is important to consider individual health needs and consult with a healthcare professional before making significant changes.

Coffee may not be beneficial for people with a BMI over 30
Coffee may have some benefits for muscle mass and weight loss, but it is important to note that these effects may not apply to individuals with a high body mass index (BMI). While coffee has been linked to higher muscle mass and a potential reduction in adiposity, these associations are not consistent across all populations.
Several studies have examined the relationship between coffee consumption and muscle mass, with conflicting results. Some research suggests that drinking coffee may be associated with higher muscle mass as we age, while others found no significant link. A study by Waseda University found that compared to those who drank less than one cup of coffee per week, people who drank more had a lower prevalence of low muscle mass. However, this study also noted that the association between coffee consumption and muscle mass did not hold true for everyone.
Additionally, coffee's potential benefits for muscle mass and weight loss may be influenced by other factors, such as BMI. According to Luke Kim, a geriatrician at Cleveland Clinic, the relationship between coffee consumption and higher muscle mass disappeared in individuals with a BMI over 30. This suggests that coffee's impact on muscle mass may be dependent on a person's BMI.
Furthermore, while some studies suggest that coffee may aid in weight loss, it is important to consider the potential negative impacts on weight as well. Coffee contains caffeine, which can interfere with sleep patterns and lead to increased sugar cravings, both of which can contribute to weight gain. Additionally, many coffee beverages are high in added sugars and calories, which can counteract any potential weight loss benefits. Therefore, it is essential to consider the overall diet and lifestyle habits when evaluating the potential benefits or drawbacks of coffee consumption for individuals with a BMI over 30.
In conclusion, while coffee may offer some benefits for muscle mass and weight loss, these effects may not extend to individuals with a BMI over 30. The relationship between coffee consumption and muscle mass is complex and influenced by various factors. More research is needed to fully understand the interplay between coffee, muscle mass, and BMI, as well as the potential mechanisms involved.
