Posted December 06, 2018 03:12:31 The caffeine you drink has a big impact on your health, but the same thing is not true of your brain, according to a new study from the University of Wisconsin-Madison.
Researchers used a new imaging technique called fMRI to study how the brain processes caffeine in the brain and the caffeine in coffee, which they say has similar effects on your body.
A team of UW-Madison researchers used fMRI scans to study the effects of caffeine on brain function and brain metabolism in rats.
The results are published in the journal NeuroImage.
The team used fMRIs to show how the two substances interact with the brain, and how caffeine alters brain chemistry in a way that is different from that of regular coffee.
“Caffeine is one of the most commonly consumed drugs in the world,” said senior author Tanya L. Deutsch, a UW-Milwaukee associate professor of physiology and neuroscience.
“It is also very important to keep in mind that it affects the brain in quite different ways than coffee, because it doesn’t have the same effect on the brain as it does on the coffee itself.”
Deutsch said the team’s findings are significant because they shed light on the role that caffeine plays in our health.
“The caffeine in a cup of coffee, if it is metabolized to caffeine in that coffee, may not have the similar effect on brain chemistry as the caffeine that is metabolizing into caffeine in regular coffee,” she said.
“But the brain metabolizes caffeine differently, so it does affect the brain differently, and that’s where the difference between regular and caffeinated coffee comes from.”
A cup of regular joe has about 60 percent of the caffeine you need to feel full, but about 10 percent of it is absorbed in the stomach, which is why people tend to take in more caffeine than they need to drink.
Regular joe is usually brewed with roasted coffee beans, while coffee brewed with hot water has a lower concentration of caffeine.
Coffee has also been shown to boost blood flow to the brain.
But the brain has different effects when caffeine is consumed in regular and hot water, Deutsch explained.
Studies have shown that when caffeine levels are high, the brain gets smaller and has a less effective sense of how much it needs to absorb.
So a smaller brain also can’t take in as much caffeine.
So the brain is also more sensitive to the effects that caffeine has on its metabolism, she said, so that caffeine in drinking can have a bigger impact on the body.
“When you take in a lot of caffeine, the body uses more energy than it needs, so the brain will be slower to get the energy it needs and will take in less of it, and then it will have a more sluggish metabolism,” Deutsch added.
Because the body has a much larger capacity for metabolizing caffeine, when caffeine in drinks is consumed with a higher concentration of it in the bloodstream, the amount of energy released from the body is increased, she added.
And that makes it difficult for the brain to absorb caffeine and use it as fuel.
When caffeine is metabolised to caffeine and the brain does not get enough of the substance to be metabolised, the activity of certain proteins in the blood vessels is suppressed.
That’s why the brain uses so much of its energy, so much more energy to use up what’s left of the energy in the body, she explained.
“So when you’re drinking a lot, the metabolism of caffeine in drink is much higher than the metabolism in the water, which means it takes more energy, and it also has a larger capacity to absorb that energy,” Deuchses said.
“It’s not just that you’re consuming a lot more energy because you’re having to drink more energy in a single drink, but you’re also consuming more of it than you’re using.”
Caffeinated coffee is not considered a healthful drink because of its caffeine content, but Deutsch says it does have benefits.
There is a big difference between drinking coffee with and without caffeine, she noted.
For example, caffeine in normal-sized cups of regular drinking is not the same as caffeine in hot water.
Even though the amount you consume depends on the amount and type of caffeine that you drink, it’s still important to drink with a small amount of caffeine if you’re going to be drinking coffee, Deuchs said.
This means that it’s important to have a low intake of caffeine for optimal health, she suggested.
However, if you are not a coffee drinker, Deuches said, you may want to consider consuming a little more of the beverage.
She recommends drinking coffee while you’re eating, not just drinking a few cups before bed.
“I don’t know of any studies that really show that caffeine is better than coffee in terms of preventing or reducing chronic diseases,” she added,
