Caffeine acts as a stimulant and helps in burning fats

Caffeine acts as a stimulant and helps in burning fats

Legend has it that a long time ago a shepherd named Kaldi realized that his sheep got more agitated when they ate the fruits of a coffee tree that had in their yard. When the pastor experienced these fruits, he also felt a sense of liveliness. Legend or not, since the fourth century BC the first reports on coffee have appeared and it is currently estimated that in Brazil its consumption comes close to 710 thousand tons or 20 million bags a year. Perhaps all this success is due to a substance present in coffee and a well-known name: caffeine.

Biochemically speaking, caffeine is classified as an alkaloid, a group of xanthines, a group also formed by theophylline and theobromine, found in chocolate. Several plants have caffeine in their composition, not being exclusive to coffee (Coffea arabica), being: mate mate (Ilex paraguariensis), guaraná (Paullinia cupana), cocoa (Theobroma cacao), tea (Camellia sinensis) and cola (Cola acuminata ).

The effects of caffeine within our body are now better understood by science. The benefits or losses will depend on one detail: the dose. Depending on the amount may be a "holy remedy," how to prevent Parkinson's disease and diabetes, according to recent studies, or its excess turn into "poison", leading to cardiac arrhythmias often fatal. The dose can be lethal close to 10,000 milligrams, but calm down as a 240-ml cup of coffee may have 90 to 200 milligrams.

The Benefits of Caffeine

Caffeine acts on the central nervous system as a stimulant direct by inhibiting the action of adenosine, being this substance a participant in the braking system of the brain, functioning as a discreet soothing. By reducing the effects of adenosine, caffeine makes our brain alert and more alert and focused, and also lessens mental fatigue.

It is possible that caffeine also stimulates the brain's production of neurotransmitters such as serotonin and dopamine, thus functioning. as a mild antidepressant. But remember: it all depends on the dose. These beneficial brain effects of caffeine occur at doses that do not exceed 300 mg / day. Above this, it can cause irritability, insomnia and even hinder concentration. In fact, people who sleep poorly due to insomnia should avoid using coffee for at least 12 hours before bedtime.

Another known effect of caffeine is to cause a dilation of the pulmonary bronchi, thus optimizing respiratory capacity. Not surprisingly, studies show that one of the reasons for athletes' better performance with prior caffeine intake before physical activity is to improve respiratory capacity with better oxygenation of muscles, thus improving their performance. Moreover, in addition to this benefit, caffeine decreases the perception of fatigue in the athlete's brain, causing it to take a little longer to achieve exhaustion. It is also known that caffeine stimulates lipolysis by inhibiting an enzyme called phosphodiesterase. What is lipolysis? I assure that it is what all chubby and also the marumbados desire: to use the fat cells (adipocytes) stored in our body to generate fuel for burning during the moments that the body needs an extra energy to maintain the muscular activities that are being required. This is the famous thermogenic effect of caffeine, that is, by turning fat into energy source there is heat generation and elevation of body temperature (thermogenesis).

How to consume

With so many known effects of caffeine inside the body important to know how to use it safely. In its natural form as found in plants (coffee, tea, chocolate, cola, mate herb) your intake is safer, but not so we should exceed the recommended dose. The suggestion of studies is that we should not eat more than 300 mg per day of caffeine (some studies suggest a maximum of 200 mg / day). Want some practical examples of this amount in food? See below:

  • 30 ml of espresso coffee: 40 to 75 mg
  • 1 xic. of 240 ml of coarse coffee: 95 to 200 mg
  • 1 xic. of 240 ml of maté tea: 27 mg
  • 1 xic. of 240 ml of green tea: 24 to 40 mg
  • 350 ml of glue-based refrigerant: 30 to 35 mg
  • 240 ml of energy drinks: 36 to 80 mg
  • 25 grams of bitter chocolate: 17 to 23 mg
  • Analgesics that have caffeine in their formula: up to 50 mg.

In the form of supplements (in capsules or similar) their use should only be done after medical evaluation. In fact, there is no official recommendation for the prescription of caffeine in medicinal doses within allopathic medicine. There are some analgesics that contain caffeine in its formula, since it potentiates the effect of the analgesic and also increases the rapidity of its absorption in the intestine. There are risks and contraindications to its use, as listed below:

  • Elderly, children and pregnant women and nursing mothers
  • Hypertension, Coronary Artery Disease and Acute Myocardial Infarction
  • Cardiac Arrhythmias
  • Hyperthyroidism
  • Generalized Anxiety Disorder or Panic Syndrome
  • Insomnia
  • Irritability
  • Gastrites (caffeine stimulates the production of gastric juice)
  • Osteoporosis (caffeine in excess increases calcium excretion in the kidneys)
  • Repeated abortion (some studies have reported an increased risk of discontinuing pregnancy with excessive caffeine intake).

Caffeine and dependence

I should also warn of the risk of developing caffeine dependence. Frequent caffeine intake with an abrupt stop can cause withdrawal symptoms such as headache, nausea, and irritability. In these cases, the decrease in your intake should be gradual, gradually and with medical guidance.

Anyway, once again the old and always accurate common sense in nutrition: everything can be weighted and in adequate doses. Respecting the contraindications save our good coffee from day to day! Or does anyone disagree?
