The wrong amount of coffee could kill you
DRINKING five coffees a day even when decaffeinated has been linked to obesity and chronic disease by WA researchers.
It is the first study in the world to look at higher doses of coffee, rather than the equivalent of one or two cups, and it found that five coffees doubled the fat around organs in the abdomen - a type of fat that causes deadly conditions.
A compound in coffee known as Chlorogenic Acid (CGA) was thought to have health benefits, such as preventing diabetes, but a new study has found too much may cause a build up of fat and other problems.
Researchers from the WA Institute for Medical Research and the University of Western Australia were hoping to prove the cardiovascular benefits of coffee, but instead discovered it can worsen obesity and its related diseases.
The researchers found that mice given an equivalent dose of five cups of coffee for a human developed twice the amount of visceral fat - the most dangerous form of fat that collects around the organs in the abdomen.
University of WA professor Kevin Croft said that previous studies had only tested small amounts of coffee equivalent to one cup of coffee a day.
“Studies have shown that coffee consumption lowers the risk of developing Type 2 diabetes,” Prof Croft said.
“With this in mind, we studied the effects of CGAs, which are very rich in coffee but also found in tea and some fruits including plums.
“The CGAs were previously known for their health benefits - increasing insulin sensitivity and reducing blood pressure and body fat accumulation,” he said.
But the study proved the opposite when dosages given to mice were equivalent to five cups of coffee for a human per day, said WAIMR Assistant Professor Vance Matthews.
“We found that the equivalent of five cups of coffee a day had a tendency to increase weight gain, particularly in regards to visceral fat,” Prof Matthews said.
“There was also increasing insulin resistance (which can lead to diabetes) and glucose intolerance in mice having high levels of CGA.”
Prof Matthews also warned people against weight loss products containing green coffee beans, which could have high levels of CGA and thus cause weight gain.
“When you have lower doses of CGA there is promotion of beneficial pathways that can break down fat, but with high levels you actually have pathways that are disregulated and you start seeing bad effects,” Prof Matthews said.
“The real message is that we need to have coffee in moderation.”
And Prof Matthews said even people who don’t look fat could have dangerous amounts of fat around their abdominal organs, which causes diabetes, cardiovascular disease and other health problems.
“There’s a lot of people who look quite lean but they have accumulation of fat in certain cells around the organs and in the liver,” Prof Matthews said. “This could be worsened by drinking too much coffee.”
“It seems that the health effects are dose-dependent. A moderate intake of coffee, up to three to four cups a day still seems to decrease the risk of developing diseases such as cardiovascular disease and type 2 diabetes,” he said.

. Alcohol, tobacco and caffeine are my only addictions these days, the easy to get drugs. If pot were legal or cheap here, or I could grow it legally I'd probably use that alot as well like I used to ages ago. I used to use speed, lsd, mda/mdma alot for 10-15 yrs or so when I was a raver, and I still use them every now and then (not speed tho) but I can go 6 months or more with having some stashed and not using it.
