How Much Caffeine In A Day Is Good For You? Experts Explain Possible Side Effects Of Increased Intake


Are you one of those who cannot start their day without a hot cuppa? Do you want caffeine to stay up and about? Is the first response to a stressful day at work only coffee? If your answer to these three questions is a Yes, then this article is certainly for you to read. 

Little do we know that coffee, like any other foods that we restrict for weight loss, should also be consumed in moderation. And, it is not just coffee that has caffeine but plenty of other easily available options that are loaded with this component, including your chocolate bars and aerated drinks, shared Nutritionist Tanvi Jiwani from Samyog Health Foods. “Commonly when we talk about caffeine, we think coffee is the only source of caffeine consumption which is not true. Cocoa, tea, soft drinks, energy drinks, chewing gum and even chocolate contain caffeine,” she explained.  

How Much Caffeine Is Good For You? 

Caffeine

According to a report by the US Food and Drug Administration (FDA), one cup of coffee contains around 80-100 milligrams of caffeine. A 350 ml bottle of a soft drink carries 30-40 milligrams of caffeine and some 240 ml of energy drink contains 40-250 milligrams of caffeine. 

The report also states that 400 milligrams of caffeine generally does not have dangerous, negative effects on healthy adults. But again, it differs from person to person. It depends on how sensitive people are to the effects of caffeine and how fast they metabolise it. However, the FDA has not set a level of caffeine consumption for children, although paediatrics discourage the idea of kids consuming caffeine in any form.

Effects Of Caffeine On the Body

In a conversation with Only My Health, Psychiatrist, Doctor Sadeq Qureshi of Prerna Hospital, talked about the effects of caffeine. When asked why and how one feels energised after a cup of coffee, Dr Qureshi said, “The reason we feel energetic after a cup of coffee is because of the stimulatory action of caffeine on CNS (Central nervous system). It acts as a CNS stimulant by antagonising adenosine receptors in the brain. Caffeine also increases dopamine release in the nucleus accumbens thus resulting in an addiction potential.”

Withdrawal symptoms include headache, fatigue, lack of concentration, irritability or dysphoric mood, nausea, vomiting & muscle stiffness.”

Dr Qureshi also mentioned other disorders like decreased desire to socialize, lesser motivation to work, decreased self confidence, disturbed sleep cycle & impairment in behavioural and cognitive performance.
