Your daily coffee habit may be quietly reshaping your gut and mood, study finds

Even decaf ... I'll have to start drinking a cup in the a.m. They mention 3-5 cups.  Woah.  That to me is a lot of coffee.

Your daily coffee habit may be quietly reshaping your gut and mood, study finds

Coffee may do more than keep you going: It could have a noticeable impact on your digestive health, even if you drink decaf.

Researchers from APC Microbiome Ireland found that habitual coffee consumption alters the trillions of microbes living in the digestive tract, creating a chemical feedback loop that directly influences mood, stress levels and cognitive sharpness.


The study followed 62 participants to determine how coffee interacts with the microbiome. The group included 31 coffee drinkers and 31 non-coffee drinkers who went through a series of psychological tests and kept detailed journals about their diet and coffee consumption...........

The researchers defined "coffee drinkers" as those consuming three to five cups daily, a range the European Food Safety Authority deems safe and moderate.

After people stopped drinking coffee for two weeks and then started drinking it again, the bacteria in their digestive systems behaved differently than the non-drinkers, according to a press release.,........

During my working days, I easily had 6 cups a day. Down to about 2.5 now, and sure do love it.

That's 300 to 500 mg of caffeine. 400 mg is what is generally recognized as the threshold before it becomes dangerous. There is nothing "moderate" about that level of intake on a regular basis.

Mine is a whole pot full of double strength Community Dark a day.  Been close to that for 50 years. 

I'd say my coffee habit shaped a lot of things.

Yeah. I was a pot or better for years and years too. 2 cups with breakfast, 1 cup in the go-cup, and the rest in the thermos before I took off... AND more, because every stop on my route had coffee around too... Somewhere between 10 and noon I would switch over to sweet tea...

Since my health went I am restricted on water, so I only fill a 42oz, jug and that's it for coffee, and accounts for 1/3 of all the water I get per day.

Funny thing though... I got sick a while back, and I was down for three weeks. No coffee, no nothing... basically chicken soup now and then, and nothing but water. When I came up out of that, I can't stand coffee anymore. Have not had it since. Dunno why.

All I know is Coffee keeps me regular.  It knows my shit.  And I trust it to perform it duty.

Speaking of coffee and the almond milk some people insist on putting in it:

@SamaHoole
Your vegan oat-and-almond latte killed more bees, drained more groundwater, and required more long-haul lorry mileage than a year's worth of dairy milk from a Welsh cow that drank rain. You will not have heard about this, because the carton has "plant-based" on it in nice green lettering.

California's Central Valley produces 80% of the world's almonds. Every almond on every supermarket shelf, in every flapjack, blended into every oat-and-almond latte from London to Berlin, started life in one valley in central California.

A gallon of almond milk requires around 162 gallons of irrigation water. A gallon of British dairy milk uses around 8 gallons of tap water, and the rest comes from rain falling on grass that grows nothing else of nutritional value to humans. The cow drinks the rain. The almond tree drinks the aquifer.

California almonds consume approximately 1.1 trillion gallons of irrigation water annually. Roughly the same volume of water used by Los Angeles and San Francisco combined. Around two-thirds of the crop is then exported to Asia and Europe. A state in repeated drought emergencies, where over a million residents lack reliable access to clean drinking water, is locking its aquifer inside almonds and shipping it overseas in containers.

Almond trees bloom for three weeks in February. To pollinate 1.5 million acres of orchards in that window, California requires roughly two-thirds of every commercial honeybee in the United States to be physically transported into the Central Valley on flatbed lorries. The largest managed pollination event on earth, every year, conducted on the back of a truck.

The bees are released into groves sprayed with neonicotinoids, which scramble their navigation. Fungicides, which weaken their immune systems. Herbicides, which have already killed the wildflowers they would normally forage on between blooms.

Between June 2024 and March 2025, US commercial beekeepers lost 62% of their colonies. 1.6 million colonies dead. The largest honeybee die-off ever recorded in American history. The trigger period for the worst losses was the months immediately surrounding the almond bloom.

Meanwhile, beneath the orchards, the ground itself is sinking. The US Geological Survey has documented parts of the San Joaquin Valley that have subsided by up to 30 feet since groundwater pumping began in the 1920s. The valley lost as much elevation between 2006 and 2022 as it lost in the previous forty-five years. The Friant-Kern Canal has lost 60% of its flow capacity because the land beneath it sank faster than the canal could be redesigned.

Once those clay aquifer layers compact, the storage is permanently lost. The aquifer is being run as a one-way withdrawal, and California has been told this in formal hydrological reports for decades.

The land was never meant to grow almonds. The bees were never meant to live on flatbed trucks. The aquifer was never meant to be a tap.

But the carton says "plant-based" in nice green lettering. So, presumably, you are saving the planet.

Carry on.
