Drinking Coffee in Moderation Every Day: The Unexpected Benefits

Coffee is well-known for its ability to boost alertness and prevent drowsiness. However, numerous studies have confirmed that moderate coffee consumption also offers various health benefits, such as reducing the risk of cancer and cardiovascular diseases, alleviating depression, and even slowing memory decline. Compared to those who rarely drink coffee, how does long-term coffee consumption impact the body?  

Coffee Effectively Reduces Facial Skin Aging Risks  

Scientists conducted a study on 16,000 individuals aged between 45 and 65, analyzing their consumption of coffee, tea, alcohol, and sugary drinks in relation to skin aging. The findings revealed that coffee was the only beverage among the four that significantly reduced the risk of facial skin aging, while no similar correlations were found with the other drinks. This suggests that coffee stands out for its potential to improve skin's resistance to aging.  

Health Benefits of Drinking Coffee  

Helps Prevent Colitis and Colon Cancer  

In November 2024, Harvard researchers published a study in *Nature Microbiology* involving tens of thousands of participants. The study found that regular coffee drinkers exhibited significant changes in their gut microbiota. Compared to those who consumed less than three cups of coffee monthly, individuals who drank three cups daily had 4.5–8 times higher levels of *L. asaccharolyticus*, a beneficial gut bacterium. This bacterium aids in the production of butyrate, which supports gut barrier function and helps prevent colitis and colon cancer.  

Supports Liver Health  

Coffee enhances liver function, similar to bolstering the body’s defense against external harm. Compared to non-coffee drinkers, regular coffee consumers are at a significantly lower risk of developing fatty liver disease. For individuals already diagnosed with fatty liver, coffee consumption can reduce the incidence of liver fibrosis by 33%. This may be due to active compounds in coffee, such as caffeine, chlorogenic acid, and kahweol, which help regulate fat metabolism, thereby preventing fatty liver and liver fibrosis.  

May Extend Lifespan  

Coffee, derived from coffee beans, contains a variety of bioactive substances, including polyphenols, caffeine, and tannic acid. These compounds neutralize free radicals generated during cellular metabolism. By eliminating these harmful free radicals, cells maintain higher biological activity, potentially extending lifespan and promoting skin health.  

Provides Cardiovascular Protection  

Coffee benefits heart health primarily due to caffeine and its bioactive compounds. Caffeine stimulates the central nervous system, increasing heart rate and blood pressure, which enhances blood flow to the heart. Numerous studies have confirmed that moderate coffee consumption significantly lowers the risk of coronary heart disease, arrhythmias, and other cardiovascular conditions.  

Reduces the Risk of Cardiovascular Disease  

A 2022 study published in the *European Journal of Preventive Cardiology* revealed that drinking 0.5–3 cups of coffee daily was associated with a 12% reduction in all-cause mortality and a 17% reduction in cardiovascular disease mortality. The study highlighted that coffee contains bioactive compounds like caffeine and polyphenols. Caffeine improves alertness and metabolism, while polyphenols offer antioxidant and anti-inflammatory benefits, protecting cells from free radical damage and maintaining organ function, particularly in the cardiovascular system.  

Enhances Athletic Performance  

Coffee boosts aerobic capacity before exercise and alleviates muscle soreness afterward.  
Note: Health is influenced by a combination of internal and external factors, including balanced nutrition, regular exercise, and other lifestyle choices. While coffee offers specific benefits, it should not be seen as a cure-all for health issues.  

Who Should Avoid Coffee  

People with Gastrointestinal Diseases  

Individuals with gastric ulcers, intestinal ulcers, or ulcerative colitis may experience worsened symptoms from coffee consumption.  

Those Recovering from Surgery or Serious Illness  

Caffeine and theobromine in coffee may overstimulate these individuals, making coffee unsuitable during recovery.  

People with Specific Medical Conditions  

Those with severe hypertension or cardiovascular diseases may experience worsened symptoms due to coffee’s stimulation of vascular constriction and sympathetic nervous system activity. Symptoms like heart palpitations and trembling may occur.  

Note: People prone to insomnia should be cautious about the timing of coffee consumption. Coffee’s half-life is approximately 5–7 hours, so it is advisable to drink it in the morning or early afternoon to avoid sleep disturbances.  

Drink Coffee in Moderation  

It is recommended to limit coffee consumption to no more than five cups per day. For healthy adults, 3–5 cups daily (120–140 milliliters per cup) is considered appropriate, amounting to a maximum caffeine intake of 210–400 milligrams.
