How Healthy is your COFFEE?

What is better to begin the day with a fresh cup of coffee in the morning? Whether at home or whilst on the move or at work.

In the past, doctors told us to reduce consumption of drinks containing high caffeine leve. Nowadays, researches found that 1-2 cups of coffee a day is actually good to health. Coffee can lower the risk of diabetes, Parkinson's disease, and colon cancer, also can lift your mood and treat headaches, and lower your risk of cavities.

According to Harvard Medical Research, a few cups a day—coffee is a safe beverage that may even offer some health benefits.

What is caffeine?

Caffeine is an alkaloid that acts as a stimulant and a mild diuretic. Caffeine is called guaranine when found in guarana, mateine when found in mate, and theine when found in tea; all of these names are synonyms for the same chemical compound.

Caffeine has the effect of temporarily warding off drowsiness and restoring alertness. Humans have been consuming plants containing caffeine since the beginning of time — it occurs naturally in many plants besides coffee and tea, even though coffee and tea get the most publicity for it.

Caffeine is added to soft drinks, especially cola-type soft drinks. I won't go into detail about it since I could spend a day on that topic alone.

Despite the negativity surrounding caffeine, caffeine continues to play a vital role in the health of people all around the world. Again, it's a topic all in itself and I won't go into detail here.

Antioxidants and Flavonoids

Both coffee and tea are high in antioxidants. An antioxidant is a molecule capable of slowing or preventing the oxidation of other molecules. Oxidation is a chemical reaction that transfers electrons from a substance to an oxidizing agent. Oxidation reactions can produce free radicals, which start chain reactions that damage cells.

Flavonoids are known as antioxidants, but they have other significant properties that I can't explain without writing a textbook or plagiarizing someone else. Green tea is higher in flavonoids than other teas, and the amount of flavonoids in coffee is questionable depending on what kind of coffee we're dealing with.

Health Benefits

Antioxidants have been proven to have anti-allergic, anti-inflammatory, anti-microbial and anti-cancer properties. Only a small amount of flavonoids are required, as antioxidants, to show immediate health benefits.

It makes sense to include coffee and tea, if you don't dislike the taste, as part of your diet. It's not known if caffeine-free versions are as effective as those containing caffeine, but it's worth trying if you're on a caffeine-restrictive diet.

Green tea has been called the green tea fat burner recently because of what it does to your metabolism and the anti-fat and anti-carcinogenic effects it has on your system.
