Coffee: Healthy or Harmful?

Early studies suggested that coffee could lead to helath problems, however recent research provide strong evidence that drinking coffee in moderate quantity actually has a variety of health benefits. This article focus on those health benefits and, on the other hand, consider some health penalty that coffee can bring.

Coffee Production & Coffee Types

Coffee is one of the most widely consumed beverages in the world, known for its rich flavor and stimulating effects. It is made from the roasted seeds of the Coffea plant, which belongs to the Rubiaceae family. The two most commercially cultivated species of coffee are Coffea arabica and Coffea canephora, also known as Arabica and Robusta.

Coffee beans are the seeds found inside the fruit of the Coffea plant. These beans are then dried, sorted, and roasted to various degrees, resulting in the characteristic flavors and aromas associated with coffee.

What Are the Differences between Arabica and Robusta?

Taste: Arabica coffee is generally considered to have a more desirable taste profile compared to Robusta. Arabica beans often exhibit a wide range of flavors, including floral, fruity, and acidic notes. On the other hand, Robusta beans tend to have a stronger, more bitter taste with earthy or nutty undertones.

Coffaine content: Robusta coffee contains almost double the amount of caffeine

compared to Arabica. Robusta beans have around 2.7% caffeine content, while Arabica beans typically contain 1.2-1.5% caffeine. The higher caffeine content in Robusta contributes to its stronger and more stimulating effect when consumed.

Market value: Arabica coffee is generally considered to be of higher quality and is associated with a higher market value. It is in higher demand due to its superior taste and more nuanced flavors. Arabica beans are often used in specialty coffee and gourmet blends. Robusta, on the other hand, is more commonly used in instant coffee, espresso blends, and as a filler in commercial coffee products due to its lower cost and higher caffeine content.

Health Benefits of Drinking Coffee

• Antioxidants: Coffee is a significant source of antioxidants, such as chlorogenic acid and polyphenols. These compounds have been associated with various health benefits, including reducing inflammation and protecting against oxidative stress.

• Mental alertness and cognitive function: The caffeine in coffee can improve alertness, concentration, and reaction time. It may also enhance cognitive function, memory, and mood in the short term.

• Liver health: Several studies suggest that coffee consumption may have a protective effect on the liver. Regular moderate coffee intake has been associated with a reduced risk of liver diseases, including liver cirrhosis, liver cancer, and non-alcoholic fatty liver disease.

It's important to note that individual responses to coffee can vary. Some people may be more sensitive to caffeine and experience adverse effects even with moderate consumption. Additionally, certain medical conditions or medications may require individuals to limit or avoid coffee intake.

The Pitfalls to Consider

• Sleep Disturbance: The stimulating effects of caffeine can interfere with sleep, especially when consumed in the evening or by individuals sensitive to its effects. It can disrupt sleep patterns, leading to difficulties falling asleep or poor sleep quality. It is advisable to limit coffee consumption in the later hours of the day to ensure restful sleep.

• Gastrointestinal Discomfort: Coffee can stimulate the production of stomach acid, leading to acid reflux, heartburn, or stomach discomfort, particularly in individuals with sensitive digestive systems. It may also have a mild diuretic effect, increasing urine production and potentially causing dehydration if not balanced with adequate hydration.

• Impact on Heart Health: While moderate coffee consumption is generally safe for most individuals, excessive intake may temporarily increase heart rate and blood pressure due to caffeine's stimulatory effects. Individuals with pre-existing heart conditions or hypertension should monitor their coffee intake and consult with their healthcare provider if necessary.

• Individual Sensitivities: Each person's response to coffee can vary. Some individuals may be more sensitive to caffeine and experience side effects such as jitteriness, anxiety, or rapid heartbeat even with moderate consumption. It's important to listen to your body and adjust coffee intake accordingly.

Why Instant Coffee Is not Beneficial for Our Body?

Instant coffee generally contains fewer nutrients compared to freshly brewed coffee. During the manufacturing process, the coffee beans are roasted, ground, and then brewed under high pressure to extract the coffee concentrate. This concentrate is then freeze-dried or spray-dried to produce instant coffee. This process may lead to some loss of antioxidants and other beneficial compounds found in freshly brewed coffee.

Instant coffee often contains additives and processing aids to enhance its flavor, solubility, and appearance. Some brands may include additional ingredients like sugar, creamers, and artificial flavors. These additives can increase the calorie content, introduce artificial elements, and reduce the overall quality of the beverage.
