Drinking four cups of coffee per day 'could reduce weight gain from an unhealthy diet' – Daily Mail

Drinking four cups of coffee per day could reduce weight gain from an unhealthy diet by stifling genes which make the body build fat, rat study finds

  • Researchers in Illinois, US, tested the effects of caffeine consumption on rats
  • They found the equivalent of four coffee cups reduced fat storage processes
  • Caffeine could be considered an ‘anti-obesity agent’, they concluded
  • Rats which consumed the stimulant built 22 per cent less body fat in four weeks

Drinking four cups of coffee per day could reduce how much fat you gain after eating unhealthy food, according to a study on rats.

The experiment discovered that caffeine stopped the body from producing as much fat in the blood and meant fat cells stored less inside them than normal.

The rats consumed the equivalent caffeine of four cups of coffee and ate a carbohydrate-heavy diet high in fat and sugar for four weeks.

They gained 16 per cent less weight than rats in a non-caffeine group and built up 22 per cent less body fat.

Scientists said this could be because the effects of caffeine reduce action in a gene which is known to contribute to weight gain.

Researchers gave rats amounts of caffeine which would be equal to that found in four cups of brewed coffee for a human, and found their weight gain was reduced by 16 per cent and their fat build-up by 22 per cent (stock image)

The researchers, from the University of Illinois, set out to see if a type of herbal tea called mate tea had health benefits, and found caffeine from coffee had the same effect.

‘Considering the findings, mate tea and caffeine can be considered anti-obesity agents,’ said Dr Elvira Gonzalez de Mejia, an author of the study.

‘The results of this research could be scaled to humans to understand the roles of mate tea and caffeine as potential strategies to prevent overweight and obesity, as well as the subsequent metabolic disorders associated with these conditions.

WHAT ARE THE HEALTH BENEFITS OF COFFEE?

Scientific studies into the health effects of coffee are being done all the time and have, in the past, claimed the drink brings fairly big health benefits.

Reduces early death risk 

Research by the National Cancer Institute in the US last year found people who drink six or seven cups of coffee each day were 16 per cent less likely to die from disease within a 10-year period than those who didn’t. 

Less likely to get depression 

Another study, done by the Harvard School of Public Health, found that women who drank four or more cups of coffee per day were 20 per cent less likely to suffer from depression. 

Women have higher pain threshold 

British scientists at Goldsmiths, University of London, found women who drank coffee – 250mg of caffeine, to be precise – tended to have a higher pain threshold than those who didn’t.

Lower type 2 diabetes 

The Institute for Scientific Information on Coffee last year said it had trawled through nearly 30 studies of almost 1.2million people to find drinking three or four cups of coffee each day could slash the risk of developing type 2 diabetes by 27 per cent. 

‘The consumption of caffeine from mate or from other sources alleviated the negative impact of a high-fat, high-[sugar] diet on body composition due to the modulation of certain enzymes in both [fat] tissue and the liver.’

Researchers gave the rats mate tea, which is a herbal hot drink popular in Latin America and packed with phytochemicals, flavonoids, and amino acids.

It contains about 65 to 130mg of caffeine per serving, compared to between 30 and 300mg (average 95mg) in a cup of brewed coffee, the researchers said.

The animals were also given synthetic caffeine and caffeine extracted from coffee to compare the effects.

They found that, regardless of its source, caffeine decreased the accumulation of lipids (fat molecules) in fat cells by between 20 and 41 per cent.

At the end of the experiment, the team said the amount of body fat on the rats which consumed caffeine and those which didn’t was ‘significantly’ different.

The study, published in The Journal of Function Foods, said the beverages could be considered ‘anti-obesity agents.’

The team explained this effect was probably caused by the effects caffeine had on two genes in particular – Fasn and Lpl.

Fasn – the fatty acid synthase gene – was about 31-39 per cent less active in the rats which were being fed caffeine, meaning the body was converting less sugar into fat.

And Lpl – the lipoprotein lipase gene – was around 51-69 per cent less active, which also reduced the amount of fat which was created.

The suppression of these genes also meant less cholesterol was produced in the liver, the study added.

Health-care announcements expected with two weeks to go in N.B. election race

Published

 on

 

New Brunswick‘s Liberal and Green parties are set to make announcements about health care on the campaign trail today as the provincial election race enters its second half.

Liberal leader Susan Holt is scheduled to hold her announcement this morning in Saint John, N.B., followed by lunch at the city’s market.

A spokesperson with the Progressive Conservative party shared few details about the event scheduled for leader Blaine Higgs in Fredericton this morning.

Green Party Leader David Coon will hold a news conference this morning about “local health-care decision-making” alongside deputy leader Megan Mitton in her Sackville, N.B. riding.

On Saturday, Coon said he was proud to put forward a gender-balanced slate among the party’s 46 candidates.

While the Liberals and Progressive Conservatives are running with full slates, the Greens are three candidates short and will not have full representation when the province’s residents go to the polls on Oct. 21.

Alberta Health Services’ snag leads to potential delay of patient referrals

Published

 on

 

EDMONTON – The Health Quality Council of Alberta is investigating how some medical referrals weren’t properly processed, potentially affecting 14,000 patients over the last five years across the province.

The referrals were made to specialists outside of Alberta Health Services, such as physiotherapists and dietitians.

The health authority’s CEO, Athana Mentzelopoulos, says it does an average 100,000 referrals per year, but in some cases it can’t confirm if patients received referral services.

She says the problem was flagged in late September, and a preliminary estimate suggests 31 patients may have experienced a potential negative outcome due to the delays.

The provincial government requested the investigation, and the quality council is to find out how the snag occurred and how it can be prevented in the future.

The health authority says it has begun notifying patients who may have been affected by the disruption, and the cases could date back to 2019.

Don’t fall for fake dentists offering veneers and other dental work on social media

Published

 on

 

WASHINGTON (AP) — If you have stained or chipped teeth, you might be considering veneers, customized teeth coverings that can restore a photogenic smile without more extensive dental work.

But dentists warn that these pricey cosmetic enhancements are at the center of a worrisome online trend: unlicensed practitioners without proper training or supervision offering low-cost veneers.

These self-described “veneer techs” often promote themselves on Instagram and TikTok, promising a full set of veneers for less than half of what dentists typically charge. Some also market their own training courses and certifications for people looking to get into the business.

It’s misleading, health professionals warn — and illegal. All states require dental work, including veneers, to be performed under the supervision of a licensed dentist.

On Thursday, Georgia law enforcement officials arrested Brandon Diller, who promoted himself to 158,000 Instagram followers as “Atlanta’s top veneer specialist and trainer.” Diller practiced dentistry without a license and sold “training and certificates, which were worthless” and “provided no legitimate or legal credentials,” according to an arrest warrant from Fulton County’s District Attorney’s office.

Here’s what to know about veneers and how to avoid bogus providers and services:

What are dental veneers?

Veneers are thin, custom-made dental coverings used to hide minor imperfections or to fill in gaps between teeth. Unlike crowns or more invasive dental implants, veneers are almost always considered cosmetic dentistry and generally aren’t covered by insurance.

Dentists usually charge between $1,000 and $2,000 per tooth for veneers, with higher prices for those made from porcelain compared with lower-grade materials.

Placing veneers involves stripping some of the natural enamel from the tooth and bonding the new covering into place. Because of that process, getting veneers is considered an irreversible procedure, according to the American Dental Association. They are not permanent, and can be expected to last between 5 to 15 years before they degrade and need to be replaced.

In recent months the ADA has been stepping up warnings about the risks of veneer procedures done by unlicensed individuals.

“Quality control is lost without the involvement of a licensed dentist,” said Dr. Ada Cooper, a New York-based dentist and ADA spokesperson. “We undergo years of education and training and need to be licensed by various regulatory bodies before we can practice.”

What are the risks of getting veneers from someone who isn’t licensed?

Improper veneer procedures can cause a range of health problems, including severe pain, nerve damage and tooth loss.

Patients need to be anesthetized before the enamel is removed from their teeth.

“It could be incredibly painful if they’re not anesthetized correctly,” said Dr. Zach Truman, who runs an orthodontics practice in Las Vegas. “You can also go too deep into the tooth and penetrate what’s called the pulp chamber, which contains blood vessels and nerves.”

One of the biggest problems Truman sees with unregulated veneer work is that customers aren’t getting screened for existing dental problems, such as gum disease and cavities.

“If you put a veneer on a tooth that has an active cavity, you’re just going to seal it in there and eventually it’s going to progress to tooth loss,” Truman said.

Dental veneers aren’t the only option for improving the appearance of teeth. Over-the-counter whitening kits can help with minor stains and discoloration. And dentists can sometimes use composite materials to reshape chipped or uneven teeth. But Truman says those fillings are prone to crack and won’t last as long as veneers.

How can I spot bogus veneer providers online?

One clue: Many individuals performing unlicensed dental work promote themselves on social media as “veneer technicians.”

Instead of working out of a dental office they often perform treatments at beauty salons, hotel rooms or private homes. Some advertise multi-city tours and encourage clients to message them to book an appointment in advance.

Much of the appeal of the services is in their pricing, with some offering a full set of veneers for a flat fee of $4,000 or $5,000. That’s less than half of what patients can generally expect to pay at a dental office.

Performing dental work without an appropriate license is illegal, the ADA notes.

Dentists and hygienists are licensed by state governments, who also define the work dental assistants can perform. But in all cases, veneers and other dental procedures must be supervised by a licensed dentist.

Earlier this year, Illinois law enforcement officials arrested a woman running a business called the Veneer Experts after she posted videos of herself fitting braces, veneers and other dental products without a license. She was previously arrested in Nevada on similar allegations of practicing dentistry without a license.

What are the best ways to find legitimate dental providers?

The ADA maintains a website detailing the training and licensing requirements for dentists across the U.S. Most states also maintain websites where you can lookup and verify licensure information and find any past disciplinary actions for dentists and other health professionals.

“It’s really critical to understand that dentistry is a regulated health care profession that requires formal educations and licensure,” Cooper said.
