Coffee: the magical companion for health and fitness

Coffee: the magical companion for health and fitness

Coffee almost firmly holds the throne as the most popular beverage worldwide. For many people, a cup of coffee in the morning is an essential ritual to start a wonderful day. The rich aroma and the energy boost and mental excitement brought by caffeine are irresistible. People from different cultural backgrounds are fond of coffee for various reasons such as social interaction, daily habits, or seeking stimulation. It can even be said that a morning without coffee companionship can make people feel at a loss. Fortunately, coffee is not just an addictive beverage. Numerous studies have shown that it is highly beneficial for our health.

Coffee helps with fitness and enhances athletic performance

Many people enjoy a cup of espresso before exercising, hoping to gain an additional advantage. Caffeine can indeed assist in exercise through various mechanisms, such as reducing perception of effort and fatigue, increasing muscle strength and explosiveness, and benefiting endurance and strength training. However, obtaining the optimal dosage for improving athletic performance from coffee is not an easy task. The recommended exercise regimen for research is to consume 3 to 6 milligrams of caffeine per kilogram of body weight. For example, for a person weighing 180 pounds, they need to consume 240 to 490 milligrams of caffeine, which may require drinking a whole pot of coffee. The caffeine content of brewed coffee fluctuates between 60 and 180 milligrams due to factors such as the type of coffee beans, preparation method, and cup size. For example, the caffeine content per ounce of espresso is higher than that of regular coffee, and the caffeine content of coffee brewed from different brands also varies greatly. This makes it difficult to accurately know the amount of caffeine ingested from coffee, and it may require drinking coffee far beyond imagination to achieve the recommended dose. Drinking 4 cups of coffee before exercising is not a good strategy if you don’t want to frequently use the restroom. Although a low caffeine level in a cup of coffee can provide some boost, the effect is far less than when consumed in high doses. In addition, people who are frequently exposed to caffeine may need to consume high-end doses of caffeine in order to experience the benefits of exercise enhancement. Therefore, some people will use supplements such as caffeine pills, chewing gum, and chewable tablets to obtain more controllable doses before important exercise, while others will combine brewed coffee with supplements to achieve the necessary level of caffeine.

Moderate consumption of coffee to avoid adverse effects

Although coffee is good, there is a situation of diminishing returns. Research has found that over 300000 adults who regularly drink 6 or more cups of coffee per day have higher levels of blood lipids, including Apo-B and low-density lipoprotein cholesterol, which are associated with a higher risk of heart disease. The New England Journal of Medicine reports that drinking two to five cups of coffee per day can reduce the risk of certain chronic diseases, but consuming more caffeine than this amount may lead to adverse consequences such as anxiety, insomnia, or psychomotor agitation. Researchers have pointed out that frequent high intake of caffeine (400 milligrams or more per day, possibly from other sources such as energy drinks) can lead to elevated blood pressure and heart rate due to its impact on the autonomic nervous system, even in healthy individuals. So, it is recommended that most people limit their caffeine intake to 400 milligrams per day, which is approximately twice the daily intake of a typical American male. Most people convert 70% to 80% of their caffeine intake into the alkaloid compound hypoxanthine, which has no significant toxic effects at reasonable doses. However, it is still important to note that excessive caffeine intake can have serious toxicological effects, including death. On the whole, it is recommended that most people should not consume more than 400 mg of caffeine per day. Pregnant women, people with anxiety, arrhythmia, hypertension, heart disease or diabetes should reduce their intake.

Reject sweet temptation and enjoy pure coffee

It is very important to develop the habit of drinking coffee without sugar. Nowadays, coffee has quietly become a carrier for adding sugar to the diet. Starbucks latte may add 40 grams or even more of extra sugar, which can offset the health benefits of drinking coffee. A 2024 study in the American Journal of Clinical Nutrition found that people who drink unsweetened coffee (regular or decaffeinated) are less likely to gain weight compared to those who drink sweetened coffee. A study in the Journal of the Society of Nutrition and Dietetics suggests that drinking coffee can prevent hypertension, but adding sugar to coffee does not have this effect. The 2024 American Journal of Clinical Nutrition report also pointed out that drinking coffee has a certain protective effect on brain diseases such as dementia, but it is not suitable for sweetened coffee. The issues related to sweetened coffee are partly due to the additional calories it provides and the impact of long-term consumption on metabolic health. An analysis by the University of Illinois shows that people who drink black coffee consume an average of about 69 fewer calories per day than those who add sugar and/or dairy products, with over 60% of calories coming from sugar and the majority from fat. In addition, data suggests that caffeine can affect the perception of sweetness, making sugary drinks and foods taste less sweet, theoretically increasing their consumption. So, if you want to reduce your sugar intake, it’s best to avoid pairing caffeinated coffee with sugary foods and drinks.

Understanding caffeine metabolism, drinking varies from person to person

There are conflicting results regarding the health effects of drinking coffee, especially in large quantities, which are related to an individual’s metabolism of caffeine. Fast metabolizers with genetic variations in CYP1A2 enzyme can accelerate caffeine breakdown. Drinking one to three cups of coffee per day seems to lower the risk of heart disease, possibly due to the antioxidants in coffee, which can quickly eliminate caffeine from the body and have a positive impact. Slow metabolizers with genetic variations in CYP1A2 enzymes may have a higher risk of heart disease if they drink two or more cups of coffee per day, as caffeine stays in their bodies for longer periods of time and negative effects dominate. Identifying which metabolic type one belongs to can help adjust caffeine intake and optimize overall health. Although it can be understood through some genetic testing, it may not necessarily be done by a doctor. Generally speaking, if one is sensitive to the stimulating effects of caffeine at lower intake levels, and side effects such as palpitations, anxiety, insomnia, and gastrointestinal problems persist for a long time after moderate coffee intake, it may be a slow metabolizer of caffeine, and it is best to drink less concentrated coffee. However, slow metabolizers may gain many health benefits from drinking decaffeinated coffee.

Coffee contains many secrets and advantages in health and fitness. From regulating bodily functions to enhancing athletic performance, as long as consumed properly, it can become a powerful assistant for us to improve our quality of life and maintain health and vitality.
