Drinking coffee doesn’t trigger diabetes, obesity

London, Maintain your love with coffee as it does not put you at the risk of developing obesity or diabetes, a gene-based study has said.

Danish researchers looked at genes as our genes play a role in how much coffee we drink in the course of a day.

So if you have the special coffee genes, you may be drinking more coffee than those not having the genes.

“We are the first to examine the link of the genes with high consumption of coffee,” said Ask Tybjaeg Nordestgaard from the department of clinical biochemistry at Herlev and Gentofte Hospital in Denmark.

“These genes are completely independent of other lifestyle factors, and, therefore, drinking coffee in itself is not associated with lifestyle diseases,” Nordestgaard added in a paper published in the International Journal of Epidemiology.

Along with researchers from University of Copenhagen, Nordestgaard analysed DNA and information about coffee drinking and lifestyle diseases from 93,000 Danes from the Copenhagen General Population Study.

The researchers studied the number of genes that affect our desire for coffee and examined whether a higher coffee consumption increases or decreases the risk of developing lifestyle diseases.

“We can see that the coffee genes are surprisingly not associated with a risk of developing Type 2 diabetes or obesity,” they said.

“This suggests that drinking coffee neither causes nor protects against these lifestyle diseases,” added Boerge Nordestgaard, clinical professor from University of Copenhagen. (IANS)

Coffee can predict Parkinson’s disease

The team involved 108 people who had Parkinson's disease for an average of about six years and 31 people of the same age who did not have the disease and consumed about two cups of coffee per day

A neurodegenerative disorder which leads to progressive deterioration of motor function due to loss of dopamine-producing brain cells. Yes, that’s Parkinson’s disease. Quite horrifying, isn’t it?

However, there maybe a chance of predicting it.

The way your body metabolises your cup of coffee each morning may determine your chances of developing Parkinson’s disease.

Findings

  • People with Parkinson’s disease had significantly lower levels of caffeine in their blood than people without the disease, even if they consumed the same amount of caffeine.
  • Thus, testing the level of caffeine in the blood may provide a simple way to aid the diagnosis of Parkinson’s disease, the researchers said.

“Previous studies have shown a link between caffeine and a lower risk of developing Parkinson’s disease, but we haven’t known much about how caffeine metabolises within the people with the disease,” said Shinji Saiki, MD at the Juntendo University School of Medicine in Tokyo.

“If these results can be confirmed, they would point to an easy test for early diagnosis of Parkinson’s, possibly even before symptoms are appearing,” added David G. Munoz, MD, at the University of Toronto.

“This is important because Parkinson’s disease is difficult to diagnose, especially at the early stages,” Munoz noted.

The main symptoms of Parkinson’s disease are tremor, slowness of movement (bradykinesia) and muscle stiffness or rigidity. Wikimedia commons

Methodology

  • The team involved 108 people who had Parkinson’s disease for an average of about six years and 31 people of the same age who did not have the disease and consumed about two cups of coffee per day.
  • Their blood was tested for caffeine and for 11 byproducts the body makes as it metabolises caffeine. They were also tested for mutations in genes that can affect caffeine metabolism.
  • The caffeine level was an average of 79 picomoles per 10 microliters for people without Parkinson’s disease, compared to 24 picomoles per 10 microliters for people with the disease.
  • However, there were no differences found in the caffeine-related genes between the two groups.

The study was published in journal Neurology. (IANS)
