But too much coffee can be harmful



According to a study led by researchers from the US-based Northwest University and QIMR Berghofer Medical Research Institute in Australia, love for tea or coffee in our genetic condition for bitter taste. It may be that bitterness acts as a natural warning system to protect us from harmful substances. The study, published in the journal Scientific Reports, examined reactions to three bitter substances – caffeine, quinine and propylthiuracil (PROP) – to understand how they affect people's preferences for drinking tea, coffee and alcohol. The results showed that people who were more sensitive to caffeine and drank a lot of coffee consumed low amounts of tea. In other words, people who have an increased ability to taste the bitterness of coffee – and especially the caffeine's clear bitter taste – teach "good things about it".

"You can expect people who are particularly sensitive to the bitter taste of caffeine to drink less coffee. The opposite results of our study suggest that coffee consumers get a taste or ability to detect caffeine due to the learned positive boost (stimulation) induced by caffeine. "said Marilyn Cornelis, deputy professor of preventive medicine at Northwest University Feinberg School of Medicine. The study also found that people who are sensitive to the bitter tastes of kinin and of PROP – a synthetic taste that are related to the compounds in cruciferous vegetables – avoid coffee. "The findings suggest our perception of bitter taste, informed of our genetics, contributes to the preference for coffee, tea and alcohol," says Cornelis.

Researchers applied Mendel randomization – a technique commonly used in disease epidemiology – to test the causal link between bitter taste and beverage consumption in more than 4,00,000 men and women in Britain.

Coffee and tea are known for being healthy drinks. Too much caffeine can also be harmful to our health. here is why:

  • Anxiety: Consuming caffeine in low to moderate dose can increase alertness, but having it in larger amounts can lead to anxiety or edginess. Monitor your own response to determine how much you can tolerate.
  • Insomnia: Caffeine helps you stay awake and awake during the day; However, it may adversely affect your sleep quality and quantity. Do not consume caffeine after early afternoon to avoid sleep problems.
  • Digestive Issues: According to health experts, small to moderate amounts of coffee or tea can improve tube motility. However, larger amounts can lead to loose stools. Reducing the intake of your coffee or teal can be useful.
  • Hypertension: Caffeine is known to raise blood pressure when consumed in high doses or before exercise, as well as in people who rarely consume it. However, this effect may only be temporary, so it is best to monitor your response.

Easy to moderate intake of caffeine can provide many impressive health benefits. However, very high doses can lead to side effects that interfere with daily life and may even cause serious health problems.
