7 Myths About Coffee That Most People Believe
It turns out coffee isn’t as bad as people think! There are more myths about coffee than we realize.
What are coffee and caffeine? Caffeine is an alkaloid that activates our nervous system, fills us with energy, and accelerates our metabolism and blood circulation. Caffeine is also contained in tea leaves, cocoa, mate, and guarana. A coffee bean contains more than 30 different organic acids including malic, citric, acetic, essential fatty acids, vitamins, antioxidants, and flavonoids. The popularity of coffee has led to countless myths about this drink that most people still believe. Let’s review them and separate myth from truth.
1) Coffee consumption leads to insomnia
How each person metabolizes coffee is different, but it doesn’t mean that coffee leads to insomnia. In coffee lovers, the genotype of caffeine-processing enzymes changes over time. As a result, their favorite drink loses its tonic effect. At the biochemical level, caffeine doesn’t activate the body but blocks the signal of fatigue.
2) Coffee leads to weight loss
Caffeine is the most frequently consumed psychoactive substance in the world. Coffee actually gives us a burst of energy and can speed up our metabolism. But if you drink coffee often, then your body has already adapted to it and its effect on your metabolism is minimal.
3) Coffee stains teeth
The tannin found in tea is a much stronger coloring agent than caffeine. A couple of cups of coffee per day effects only a thin layer of bacteria that covers the teeth and gums and doesn’t actually penetrate the enamel itself. Good whitening toothpaste can easily handle this small downside. But if you love drinking your cup of coffee along with a cigarette, teeth-whitening toothpaste won’t be as effective.
4) Coffee leaches the body’s calcium
If you consume a lot of caffeine (more than 744 mg per day which is equivalent to about 12 standard cups of espresso), this can impair the intestinal absorption of calcium. However, studies show that it’s enough to add 1 to 2 tablespoons of milk to your coffee to offset this negative effect of excess caffeine.
Nevertheless, older people should be careful since coffee consumption has some effect on hip fractures. There is an assumption that caffeine has a more powerful effect on body calcium loss in old people.
5) Coffee leads to cancer
None of the numerous studies have established a relationship between caffeine consumption and the development of any type of cancer. There are actually valid reasons to assume that coffee may even reduce the risk of certain types of cancer.
6) Coffee causes constipation
Some people believe that long-term coffee consumption increases the risk of constipation because it dehydrates the body and provokes hard stool. However, this isn’t entirely true. Coffee stimulates the secretory and motor activity of the gastrointestinal tract.
7) Coffee dehydrates
Caffeine has a mild diuretic effect and it doesn’t lead to dehydration. But if you drink 2 to 3 cups of strong coffee in a row, the diuretic effect may become more pronounced. However, such an increase in the urge to use the toilet is observed only in those people who practically didn’t drink coffee before.
