  • by

In this week’s video we are talking about one of the most popular beverages in the world – coffee. Is coffee good for you? What effects does it have on your body? And the biggest question, does it have any health benefits? This week, we talk about it all.

Hi folks welcome back to coffee with ravi today i thought i’d do a little uh fun topic which is about coffee is coffee good for your health and what does caffeine do to the body coffee and tea are among the most popular beverages in the world a variety of plants which start with coffee tea cocoa beans from which chocolate comes from and yerba mate and guarana

Berries which are other products that can have caffeine caffeine of course is added to certain other artificial drinks like monster or red bull and energy shots and tablets the caffeine content is variable in various beverages the important thing that i want to point out is that coffee has certain other biological active substances like chlorogenic acid alkaline

Trigonally and there’s also a specific substance called melanoidin which is produced during the roasting of coffee these seem to have some beneficial effects because they’re in they have certain other uh biological activity on the human body which may be of some benefit as we’ll get into a common question that i get asked is what’s the common caffeine content in

Each cup that we consume of coffee the a 12 ounce cup of coffee that’s brewed the standard way such as in a coffee shop has about 235 milligrams of caffeine in it a shot of espresso has 63 milligrams energy shots can range anywhere from 80 to 100 some some of the over-the-counter drugs for alertness have about 200 milligrams and headache medicine with caffeine has

65 milligrams with it so there’s a whole range of it coffee is normally absorbed within 45 minutes of taking coffee and peaks shortly after that and lasts for about two hours the thing to realize is that as coffee is metabolized some people metabolize it faster and some people metabolize it slower in fact there’s some genetic tests available to check with that

Smoking seems to accelerate it in other words if one smokes and drinks coffee the caffeine is metabolized out of the system faster pregnancy on the other hand seems to slow down the metabolism of caffeine there are certain drugs like ciprofloxacin some cardiovascular drugs albuterol type inhalers etc that can actually increase the level of caffeine because

They slow the metabolism down the next slide which looks at caffeine intake on different organ systems and i’ll go through it because i think this is really the meat of the talk caffeine on the brain we all know increases the mental performance and alertness however if taken later as we know in the day it can cause insomnia and high doses and some people can

Cause anxiety it’s been shown to reduce the risk of depression and can be added have additive effect on the effects of nsaids on headaches there is some suggestion of data that it may slow the risk of parkinson’s developing parkinson’s disease so those are the effects on the brain caffeine has been used in the medical field to treat apnea or breath holding in

Premature infants it seems to be a slight improvement in the ways that lungs function with caffeine on the liver it seems to decrease the risk of liver scarring cirrhosis and cancer on the kidney tract we all know that the more coffee we drink the more times we go to the bathroom because that causes the body to push out more water on the heart on the short term

It raises the blood pressure but doesn’t seem to have any long-term side effects patients people who drink coffee on the long term the blood pressure it doesn’t have an effect on the endocrine system it helps overall not helps but rather initially slows down the effect on how the insulin acts on the muscle but i think that’s a very transitory side effect and

Goes away so in other words it’s a wash as it relates to the endocrine system on the reproductive system especially in females there’s a little risk of slowing fetal growth and increasing the risk of pregnancy loss so that’s something to think about during pregnancy can you get coffee poisoning rare but can happen in the following scenario in general you need

One needs to get down about 75 to 100 cups of coffee standard coffee over a very short period which is very hard to do but can happen with energy drinks or tablets especially energy drinks with alcohol there’s been some suggestion that of case reports where people get admitted with cardiovascular heart related side effects so the habit of a red bull with vodka

Or those kind of combinations need to be avoided on chronic disease there’s really no bad effect on the heart system there seems to be a slight effect in raising good cholesterol there’s a small effect of if one consumes about three cups of coffee per day of decreasing the risk of stroke and it seems to increase the way your body processes food in other words

It raises the metabolism there’s a decreased risk of melanoma skin cancers and non-melanoma skin cancers as well as breast cancer and prostate cancer if you look at it as a group these are small trends the thing to understand about literature with coffee is that sometimes it’s hard to study these are retrospective in the sense that people need to remember how

Much they drink so it’s really not very accurate data but within the realm of interpreting data these are the trends so in other words these are trends don’t take it to the bank in conclusion i think based on this review that coffee is safe and can perhaps reduce the risk of several chronic diseases safe limits seem to be up to about 400 milligrams in adults

And 200 milligrams for pregnancy uh and lactating women so if you’re enjoying a cup of coffee go ahead do it without guilt but watch the effects it has on you thank you for joining us today
