Coffee beverage
Stuffs that during brewing dissolve in water to create the drink which are classified as nonvolatile taste components (comprises of caffeine, trigonelline, phenolic acids, chlorogenic acid, carbohydrates, amino acids and other minerals) and volatile aroma components comprise of organic acids, aldehydes, ketones, esters, amines and mercaptans.
A cup of coffee, depending on its strength might contain some 10-100mg of caffeine. Some types of coffee might as well contain important amounts of the B-vitamin niacin, even though this nutrient is of course with pleasure accessible from other foods as well.
Caffeine-containing tablets or medications need not be taken as well as cups of coffee or tea, as this would again increase the true value of dosage. The effects of caffeine differ from person to person; some individuals may drink several cups of coffee in an hour and may also have zero effects, while other person may feel a strong effect after just one serving.
Caffeine is actually a drug, which has been widely used for centuries. Its main effect is that it is a soft stimulant of central nervous system (CNS), assisting to decrease feelings of tiredness and fatigue. However, usual use might lead to “habituation”; that is, no net advantage from use but, rather, a negative effect if the drug is not actually taken.
Besides the above mentioned CNS stimulant outcome, caffeine as well temporarily increases heartbeat, increases the blood pressure, and further stimulates the action of the lungs; increases basal metabolic rate (BMR), and help to promotes urine production; and it also relaxes smooth muscles, particularly the bronchial muscle.
Caffeine is well used in treating migraine disease, either alone or in combination. It enhances the action of the ergot alkaloids, which is used for the treatment of this problem, and further increase the potency of analgesics such as aspirin. It could to some extent relieve asthma attacks by dilating the bronchial airways.
Caution and Warning
Too much of caffeine could also produce restlessness, nausea, headache, tense muscles, cardiac arrhythmias (irregular heartbeats) and sleep disturbances. Because caffeine increases the production of stomach acid it might even worsen ulcer symptoms or cause acid reflux (heartburn). Consuming coffee in evening might disrupt sleep and may cause insomnia.
Caffeine needs to be used with caution by people with heart disease and people with high blood pressure (hypertension), and also by those people who are suffering from eye disease glaucoma.
Caffeine medications must not be generally taken by children. Many children are already drinking huge amounts of caffeine in drinks and food. In this connection, a nutritional concern is that children might select fizzy drinks in preference to milk, thus getting zero calories at the expense of valuable nutrients.
