Coffee contains many substances that help normal functions of our organisms. Among them the potassium helps the contraction of the muscles, preventing cramps, sprains, etc. As a consequence helps the most important muscle: the heart.
The magnesium carries on a fundamental part in the nervous system and the calcium, as you know, nourishes and makes bones and teeth strong. The manganese and the chrome favour the metabolism of carbohydrates and the enzyme activities inside the cells.
A cup of coffee a day is deprived of energy-giving value (2 calories only), and so it doesn't fatten like many people think, for this reason the W.H.O. (World Health Organization) doesn't consider it a nourishment, the coffee fournishes with vitamins such as E (antioxiding) and the PP maintaining integral the tissues and the nervous system.
As you know, also thanks to the already cited substances, an usual and moderate consumption is an excellent stimulant for the central nervous system and develops a very good cardiotonic action, helping so the cardiovascular system. Of course, in peculiar cases of cardiopathies or however in the presence of stressing situations for the heart, it's necessary to set a limit to the consumption. Coffee isn't a doping substance; it contributes to the glycogen formation in the blood, the favourite "petrol" for the muscles, during the resistance works.
It's not true that coffee keeps the high pressure! In case –if it's drunk occasionally- causes a negligible and temporary raising of the usual values, it can be useful in hypotension cases and sudden faints. It must be avoided in cases of kidney origin hypertension.
It's not true that coffee is carcinogenic, on the contrary its beneficent functions on the intestinal functions prevent the colon and rectum cancers. Moreover the beans contain several anticancer agents remaining intact after roasting: studies about animals have revealed a decrease by 60% in arising of mammary cancers and by 90% in oral ones.
It's not true that the coffee-cup increases the cholesterol: in fact, once filtrated, the boiled coffee doesn't present those fats that could increase the values.
Its not true coffee brings on arrhythmies and extrasystoles: their cause must be looked for in something else. Like any excitant causes heart-throbs increases in relation to the ingested quantity, but surely we aren't in pathologies field!
If you suffer from hemicrania, the consumption of coffee increases the pain-relieving medicine effects.
If you suffer from asthma three coffee- cups every day keep away the fits; in fact the caffeine, once ingested, resolves in theophylline, this substance is prescribed for the asthma treatment.
It's showed scientifically that the caffeine favours the production of
saliva and gastric juices, and then it favours the digestion, it helps
the biliary secretion and, as already said, the functions intestinal
generally. It even acts on the diuresis, inhibiting the Adh, antidiuretic
hormone.
At last the coffee helps the thermogenesis, that is the self-regulation
skill of bodily temperature and, moreover, attenuates the pangs of hunger,
very precious function during the slimming diets.
