caffeine in coffee

Can’t do without your daily espresso? Hooked on caffeine? Well, the answer may lie in genes you inherited!

The time taken by your body to break down caffeine is determined by a gene called CYP1A2. Your liver is likely to clear caffeine faster from your body, if both your parents pass down the “fast” form of the gene. However, it is the opposite in case one or both parents pass on the “slow” form. The time taken by the liver to process the caffeine is four times longer in the latter situation.

Medical studies by Mayo Clinic, the Erasmus Medical Center, etc, show that your genes play a major role in determining the impact of coffee on your body. Its effect is based on the metabolism of your body.  If drinking normal, filtered 8-ounce cup of coffee within an hour doesn’t lead to a headache, abnormal heartbeats, anxiety, gastric upset, then you have a fast metabolism.

The fast metabolizers are likely to get a calm sense of heightened focus, if they drink two to three cups of brewed coffee. On the other hand, just one cup of it can make the people with slow metabolism stressed out or nervous. It can also lead to a headache or palpitations.

Coffee consists of a plant nutrient which is healthy for the heart. It also helps in opening the blood vessels due to the presence of caffeine in it. Thus, the risk of heart attack is decreased by drinking one to three cups a day for fast metabolizers. On the other hand, the heart attack risk increases for the people with slow metabolism. Similarly, the risk of hypertension is reduced by drinking coffee for fast metabolizers but increases for the slow metabolizers.

Caffeine is widely known for its use in boosting the athletic performance. As a matter of fact, a higher increase in endurance of the muscles is experienced by the fast metabolizers. A survey conducted on male cyclists highlighted that time of fast metabolizers was improved by 4.9 perfect. In contrast to this, the time of slow metabolizers was improved just by 1.8 percent.

Coffee offers a number of benefits and is of great help in the digestion process. The gastric acid is stimulated by it which helps in breaking down the proteins in food. It is also effective in reducing the risks of type 2 diabetes, many cancers, Alzheimer’s disease, and Parkinson’s disease.

The antioxidants and beneficial nutrients present in coffee are of great help in improving your overall health. Apart from increasing the energy and adrenaline levels, coffee blocks an inhibitory neurotransmitter called Adenosine in the brain, due to the presence of caffeine. It helps in improving various aspects of the brain like memory, mood, vigilance, energy levels, reaction times and general cognitive function.

Medical studies show that caffeine helps in burning the body’s fat and boosts the metabolic rate. It breaks down the body fat and releases them into the blood as free fatty acids. Coffee also brings about a significant improvement in the overall physical performance of the body.

Clearly, the risks associated with coffee are outweighed by the extensive benefits offered by it.
