Health Benefits of Coffee

Some of the most impressive health benefits of coffee include its ability to improve cognitive health, protect the cardiovascular system, reduce the chances of developing diabetes, aid in weight loss efforts, boost energy levels, maximize fitness efforts, increase liver protection, optimize the metabolism, and protect against certain types of cancer.

Coffee
Known around the world for its wide variety of taste and stimulating nature, coffee is one of the most popular beverages on the planet, with 100 million daily drinkers in the United States alone. Billions of cups of coffee are drunk every day around the world; estimates put the total at 500 billion cups every year. When something is that universally celebrated and enjoyed, there must be something besides an energy boost and a well-blended flavor. Coffee is not typically thought of as a healthy drink, but it actually has some surprising side effects, many of which are due to its chemical components and nutrients. Coffee itself comes from coffee beans, derived from the coffee plant. Coffea arabica is the most commonly used bean, but there are many different varieties depending on the region of the world you are drinking coffee in, or on where you are importing the beans from.

Coffee represents the top agricultural export for 12 countries of the world, and despite its slightly acidic and addictive nature, it continues to be demanded from Japan to New Jersey in massive quantities. Historically, coffee was first recorded as a drink just over 500 years ago, beginning on the Arabian peninsula, but there is speculation that its use as a stimulating beverage stretches back more than 1,000 years in various ancient and indigenous cultures. Now, coffee is drunk in nearly every country of the world, and the cultivation and processing of coffee is the prime source of income for more than 100 million people around the world.

Nutritional Value of Coffee
Although most people think of coffee as nothing but hot water and coffee grounds, people forget that coffee beans for have important organic compounds and nutrients, including a range of B-family vitamins, including riboflavin, pantothenic acid, and niacin, as well as potassium, manganese, and magnesium. Perhaps most importantly, coffee contains caffeine, which has a wide range of health benefits when consumed in moderation and at right times during the day.

Health Benefits of Coffee

Cognitive Health: It is widely known that coffee helps to sharpen focus and increase attention by stimulating the brain with caffeine. While this can sometimes result in a mental crash if too much coffee is consumed, the regular process of drinking caffeinated coffee has been shown to protect cognitive health and prevent mental degradation as we age. In fact, studies have shown that elderly people who consume coffee on a regular, moderate basis are 60% less likely to develop Alzheimer’s and dementia. Keeping those synapses firing with some caffeine isn’t a bad idea!

Cardiovascular Health: Although too much caffeine can put strain on your cardiovascular system, research has revealed that regular coffee drinkers can actually reduce their risk of having a stroke, and in females, coffee seems to decrease the risk of heart disease. While coffee can increase blood pressure, that is more of a temporary side effect, rather than a permanent effect, and temporarily raised blood pressure does not mean that a stroke or heart disease is inevitable. It can often work to clear out the system and keep your cardiovascular system functioning at a high level.

Diabetes Prevention: This is a relatively new benefit learned about coffee, but in recent years, studies have shown that people who regularly consume coffee have a 23-50% lower chance of developing diabetes. The study covered nearly half a million people, and returned some very interesting results. This could be due to the appetite suppressing effects of coffee, or the fact that it simply makes you more energized and active, helping to reduce your risk factors for diabetes.

Metabolic Health: One of the most essential roles of B vitamins in our body is to regulate and guide our metabolic activity. The significant levels of niacin, pantothenic acid, and riboflavin mean that coffee helps us optimize our metabolic efficiency so we use nutrients efficiently, maintain balanced hormone levels, and generally keep our body running smoothly.

Weight Loss Efforts: An overlooked benefit of coffee is that it energizes people to move around, get active, and burn calories faster. The actual stimulant nature of caffeine speeds up the body’s metabolism briefly and increases calorie burning when coffee is drunk. Furthermore, coffee acts as an appetite suppressant, so you can calm cravings and remain firm in your dieting goals with a cup of joe on your side!

Maximize Fitness Goals: Many people who regularly work out or train in a gym use coffee as a final burst of energy so they can get the most of their workout. That burst of caffeine acts as instant energy, allowing people to push themselves a bit longer and a bit harder to really begin seeing results from their exercise regimen.

Liver Protection: Although this is still an area that is being heavily researched, coffee consumption has been linked to liver health, particularly in the prevention of cirrhosis, hepatitis, and fatty liver disease. One study showed that regular coffee consumption resulted in an 80% reduced chance of developing cirrhosis of the liver.

Cancer Prevention: It seems that everyone is always looking for the magical anti-cancer cure, as the disease is one of the most deadly and widespread on the planet. Coffee is not traditionally thought of as anti-carcinogenic, but it has been linked specifically to two types of cancer prevention – liver and colorectal cancer, which are the 3rd and 4th deadliest forms of cancer, respectively.

Depression and Mood: The natural effects of coffee are to energize and activate the mind and body. This can do wonders for someone suffering from depression, and has even been connected to a reduced occurrence of suicidal tendencies. However, coffee has been connected to anxiety and mood swings if consumed in excess, because the classic caffeine crash can be quite severe as the chemical’s effect runs out. Remember – everything in moderation!

Arabica and Robusta Coffee Plant

Coffee Plant Overview

The coffee plant is a woody perennial evergreen dicotyledon that belongs to the Rubiaceae family. Because it grows to a relatively large height, it is more accurately described as a coffee tree. It has a main vertical trunk (orthotropic) and primary, secondary, and tertiary horizontal branches (plagiotropic). 

The Difference Between Arabica and Robusta Coffee Beans

While there are several different coffee species, two main species of coffee are cultivated today.  Coffea arabica, known as Arabica coffee, accounts for 75-80 percent of the world's production.  Coffea canephora, known as Robusta coffee, accounts for about 20 percent and differs from the Arabica coffees in terms of taste. While Robusta coffee beans are more robust than the Arabica plants, but produces an inferior tasting beverage with a higher caffeine content.  Both the Robusta and Arabica coffee plant can grow to heights of 10 meters if not pruned, but producing countries will maintain the coffee plant at a height reasonable for easy harvesting.
 
Coffee Plant Growth and Development
Three to four years after the coffee is planted, sweetly smelling flowers grow in clusters in the axils of the coffee leaves.  Fruit is produced only in the new tissue.  The Coffea Arabica coffee plant is self-pollinating, whereas the Robusta coffee plant depends on cross pollination.  About 6-8 weeks after each coffee flower is fertilized, cell division occurs and the coffee fruit remains as a pin head for a period that is dependent upon the climate.  The ovaries will then develop into drupes in a rapid growth period that takes about 15 weeks after flowering.  During this time the integument takes on the shape of the final coffee bean.  After the rapid growth period the integument and parchment are fully grown and will not increase in size.  The endosperm remains small until about 12 weeks after flowering.  At this time it will suppress, consume, and replace the integument.  The remnants of the integument are what make up the silverskin.  The endosperm will have completely filled the cavity made by the integument nineteen weeks after flowing.  The endosperm is now white and moist, but will gain dry matter during the next several months.  During this time the endosperm attracts more than seventy percent of the total photsynthesates produced by the tree.  The mesocarps will expand to form the sweet pulp that surrounds the coffee bean.  The coffee cherry will change color from green to red about thirty to thirty-five weeks after flowing.  See Flash movie on Coffee Bean Development.
 
Coffee Plant Root System
The roots of the coffee tree can extend 20-25 km in total length (Malavolta, 195) and the absorbing surface of a tree ranges from 400 to 500 m2 (Nutman).  There are main vertical roots, tap roots, and lateral roots which grow parallel to the ground.  The tap roots extend no further than 30-45 cm below the soil surface.  Four to eight axial roots may be encountered which often originate horizontally but point downward.  The lateral roots can extend 2 m from the trunk.  About 80-90% of the feeder root is in the first 20 cm of soil and is 60-90 cm away from the trunk of the coffee tree (Mavolta, 195-196).  However, Nutman states that the greatest root concentration is in the 30 to 60 cm depth.  The roots systems are heavily affected by the type of soil and the mineral content of the soil.  To be thick and strong, the coffee roots need an extensive supply of nitrogen, calcium and magnesium. During planting the main vertical roots are often clipped to promote growth of the the horizontal roots, which then have better access to water and added nutrients in the top soil.
 
Coffee Leaves
The elliptical leaves of the coffee tree are shiny, dark green, and waxy.  The coffee bean leaf area index is between 7 and 8 for a high-yielding coffee (Malavolta, 195).  The coffee plant has become a major source of oxygen in much of the world.  Each hectare of coffee produces 86 lbs of oxygen per day, which is about half the production of the same area in a rain forest (source: Anacafe).

What’s the Difference Between Robusta and Arabica Coffee?



   
It’s time to put on your learning caps and brew yourself a fresh cup of coffee—it’s time for some bean knowledge!  Coffee aficionados of all levels have without a doubt heard the words “Robusta” or “Arabica”. If you aren’t familiar with either, these two terms describe the two different species of beans grown commercially. They are the same in that when harvested, roasted and eventually brewed to become that magical thing we call coffee. However, that’s where the similarities end. Robusta and Arabica differ when it comes to taste, growing environments and quality:

Taste
Robusta has a neutral to harsh taste range and is often likened to having an “oatmeal-like” taste. When unroasted, the smell of Robusta beans is described as raw-peanutty.
Arabicas, on the other hand, have a very wide taste range (depending on its varietal). The range differs from sweet-soft to sharp-tangy. When unroasted, Arabica beans smell like blueberries. Their roasted smell is described as perfumey with notes of fruit and sugar tones.

Growing environments
Robusta coffee beans come from a resilient plant that is able to be grown in low altitudes of 200-800 meters. Robusta beans aren’t very susceptible to damage done by pests. Additionally, they produce more finished product per acre and require fairly low production costs.
Contrariwise, Arabica coffee beans are fragile and must grow in cool, subtropical climates.  Arabica beans also need a lot of moisture, rich soil, shade and sun. Because of their fragility, Arabica beans are vulnerable to attack from various pests and can be damaged by cold temperatures or poor handling. This type of bean also needs to be grown at a higher elevation (600-2000 meters).

Which bean is better? 
No contest!  If you had to choose between an Arabica bean and a Robusta bean, it’s important to always choose Arabica.
Robusta fosters use mono-cropping, the practice of growing the same plant every year in one place. It yields more space since it involves clear-cutting the forest for the crop. Because Robusta is more a resilient plant than the delicate Arabica, it can be grown in more places. Large coffee companies buy huge amounts of rainforest, clear-cut the land and plant Robusta beans. Robusta is often mixed with Arabica,  allowing the coffee companies to save a pretty penny and serve you a crappy cup. Not to mention, mono-cropping, when done excessively, also erodes soil and demolishes nutrients making the soil nearly unusable.
