Coffee, the mayor nature source of caffeine, is a wonderful natural energy drink with lots of physiological and pharmacological properties. Either if you are a coffee lover or you are under a muscle building or weight loss program, perhaps you should consider to empower your day by adding a caffeinated drink to your daily routines.
Tip: the average cup of filter coffee contains 140mg of caffeine compared with 100mg in instant coffee and only 75mg in tea. Caffeine is absorbed in the small intestine, metabolised in the liver cell and distributed to body tissues within 45 minutes of ingestion.
Though coffee has a long history of being blamed for many ills, recent research indicates that coffee may not be so bad at all.
What are the benefits of coffee?
The power of coffee
- Coffee increase lipolysis and energy expenditure thus being a perfect partner for weight loss or body sculpture plans.
- Increase body resistance and performance. Caffeine competitively inhibits phosphodiesterase, the enzyme that degrades cyclic AMP (the energy molecule), thus increasing cyclic AMP (the every molecule of the cell). In addition, it stimulates the release of hormones. In particular: epinephrine (adrenaline), making the body more active. Studies show that people who ingested a drink containing 179mg of caffeine one hour before training, were able to complete significantly more repetitions to failure than those who ingested a placebo. The study covered a variety of resistance exercises, including the bench press, dead-lift and back squat.
Many controlled trials in humans show that coffee improves brain function including memory, mood, vigilance, energy levels, reaction times and general cognitive function.
- Coffee contains essential nutrients such as Riboflavin (Vitamin B2), Pantothenic Acid (Vitamin B5), Manganese and Potassium, Magnesium and Niacin (B3).
- Coffee has a high content of antioxidants (with beneficial roles in disease prevention and treatment).
- Furthermore coffee may protects you against diseases, such as Cardiovascular disease, Parkinson's disease, Alzheimer and Dementia, Type 2 Diabetes, Liver Cirrhosis, and Liver and Colorectal Cancer. Recent studies did not found any connection between coffee and an increased risk of cancer or heart disease like previously thought. The reason being because earlier studies didn't always take into account known high-risk behaviours. For example, smoking and physical inactivity, tended to be more common among heavy coffee drinkers.
- Since drinking coffee make us less prone to disease, coffee can also make us live longer with a lower propensity to develop depression.
All these reasons make of coffee "the perfect life partner"
but ... any buts?
However, although coffee may not be very harmful, it usually goes with cream and sugar which add fat and calories to your diet. Furthermore, hight caffeine intake (4-8 cups of coffee a day) can cause problems such as restlessness, anxiety, irritability and sleeplessness, particularly in susceptible individuals, and might even give a positive result on a doping test due to cyclic AMP release, so like everything else …
