How long will it take to burn off these calories?: The controversial next step in nutrition labeling – The London Free Press

Critics say putting exercise calorie counts on food packaging would only reinforce the notion that exercise earns people the right to eat ‘crappy foods’

According to scientists, Brits consume, on average, 6,000 calories on Christmas Day alone.

So, in an experiment published last year in the British Medical Journal, U.K. researchers explored whether providing people with the amount of exercise required to burn off the calories in, say, a single piece of mincemeat pie (21 minutes of running) or one small Christmas pudding (a staggering 110-minute run) would help prevent weight gain over the holidays.

In fact, they found participants in the “brief intervention” group exposed to this new kind of food labelling ended the holidays weighing 0.5 kg less, on average, than a comparison group.

Now, in a new review and analysis that pooled data from 14 randomized controlled trials, some of the same collaborators are reporting that when labeling known as PACE — physical activity calorie equivalent — is displayed on menu items, people consume, on average, 65 fewer calories per meal compared with other types of labeling, or no labeling.

It may not sound like much. However, the average person eats three meals a day, plus two snacks — five separate eating occasions where PACE might nudge people to reduce their total calorie intake by 200 to 250 calories a day, said Amanda Daley, of the School of Sport, Exercise and Health Sciences at Loughborough University.

“In the U.K., the guidance is that if you want to lose weight then you should look for a deficit of 500 calories per day, so already you could see how PACE could cut into that 500 calories,” she said.

The Royal Society for Public Health in the U.K. is already calling for PACE labeling on the front of food packaging.

But not everyone is so enthralled. Some worry it could lead to an exercise/eating disorder nightmare. “We know that many people with eating disorders struggle with excessive exercising, so being told exactly how much exercise it would take to burn off particular foods risks exacerbating their symptoms,” Tom Quinn, of the eating disorders charity Beat, told the BBC.

“Quite honestly, we have as a society, over quite a long time really, only focused on exercise as a means to manage weight or burn calories when it is poor at both,” said obesity specialist Dr. Yoni Freedhoff, an associate professor of family medicine at the University of Ottawa.

One advantage around PACE is that it tells people what it takes to burn that muffin or that Frappuccino

Freedhoff’s issue with the idea of putting exercise calorie counts on food packaging is that it would reinforce those messages, as well as the notion that exercise earns people the right to eat “crappy foods.” (In a related tweet, he also worried it could reinforce weight bias by suggesting people struggling with obesity are “lazy gluttons.”)

The idea that some “magical set of instructions” will lead everybody to make healthier choices is, well, magical thinking, he said, when the wider problem is the constant provision of junk food at every turn.

“And if you discourage the consumption of junk food and simultaneously discourage people from exercising, I don’t think that’s a public health win,” Freedhoff said.

Daley, however, argues that traditional nutritional labeling is difficult for the public to grasp and doesn’t provide any context or meaning. Many people don’t understand the meanings of calories or grams of fat in terms of energy balance, she and her coauthors wrote, and studies show the public consistently underestimates the number of calories in food. “Just putting numbers on a packet really has no relevance,” Daley said.

“One advantage around PACE is that it tells people what it takes to burn that muffin or that Frappuccino,” she said. It could help people decide whether the calories are “worth it.”

Some festive examples include: one thick slice of roast turkey (roughly 100 calories) would require 16 minutes of walking, three large roast potatoes (161 calories) 27 minutes of walking and one small Christmas pudding (1,280 calories) 110 minutes of running.

According to the formula, 100 calories is about 10 minutes of running and 20 minutes of walking for an 80kg man (the average weight for a man).

Daley said there is no evidence to date that physical activity campaigns lead to unhealthy or disordered eating. Obesity is related to cancer deaths, cardiovascular deaths and stroke, among other killers. “We’re interested in trying to save lives from those diseases,” she said.

Ultimately the researchers would like PACE to be seen on labels in supermarkets, on packages, and particularly on menus in restaurants and fast food outlets. “All those types of places where we eat high-calorie foods would be a really good place to start.”

There are some caveats: Most of the studies Daley and colleagues analyzed were small, and based on lab settings or “hypothetical meal selection scenarios,” not real life ones.

Canadian experts caution against temptations to comparison shop COVID-19 vaccines – Kelowna Capital News

Published

 on


While it’s tempting to compare various aspects of AstraZeneca-Oxford’s newly approved COVID-19 vaccine to others, several experts cautioned against focusing on data that is not comparable and the danger of underrating the product’s ability to curb hospitalizations and deaths.

Health Canada’s long-awaited announcement Friday that a third vaccine would soon be deployed came just as the provinces faced heightened scrutiny over regional immunization plans that vary by timeline, age eligibility and priority groups.

Prime Minister Justin Trudeau promised the boost to Canada’s pandemic arsenal would mean “more people vaccinated, and sooner,” and would be key to helping contain spread.

Nevertheless, Health Canada chief medical advisor Dr. Supriya Sharma acknowledged questions over how the public should evaluate trial results that show AstraZeneca has an efficacy of 62 per cent in preventing symptomatic cases. That’s compared to the 95 per cent efficacy of the country’s two other approved vaccines, from Pfizer-BioNTech and Moderna.

But Sharma stressed that all three have been shown to prevent 100 per cent of hospitalizations and deaths due to COVID-19.

“Each vaccine has unique characteristics and Health Canada’s review has confirmed that the benefits of the viral vector-based vaccine, as with the other authorized vaccines, outweigh their potential risks,” Sharma said.

Several medical experts including Dr. Stephen Hwang say Canadians do not have the luxury to pick-and-choose as long as COVID-19 cases continue to rage in several hot spots and strain health-care systems.

With multiple COVID-19 projections warning of a variant-fuelled third wave without tighter suppression measures, any tool that can slow the pandemic should be embraced, he argued.

“It would be important for people to be vaccinated with whichever vaccine is first available in their community to them, rather than trying to hold out for a specific vaccine,” advised Hwang, who treats COVID-19 patients at St. Michael’s Hospital in Toronto.

Still, Toronto resident Maria Brum couldn’t help but question whether AstraZeneca was safe for her 79-year-old mother.

The vaccine was not tested on people over the age of 65. Health Canada, however, says real-world data from countries already using the product suggest it is safe and effective among older age groups, promising an update on efficacy in the age group as more data comes in.

“I personally would take that one out as an option for my mom,” said Brum, who is her mother’s main caregiver.

“Maybe I am wrong but, I don’t know, I don’t see that it’s more useful. I’d like to see one that has a higher percentage of (efficacy).”

As for herself, Brum said she has allergies that she believes may put her at greater risk of adverse reactions and so she is unsure whether she can take any vaccine.

But she’d like the option of choosing, if possible, even while acknowledging that limited supply could make that unlikely.

“As a Canadian, I would like to see us all have choices, regardless of age, gender, or ability,” says Brum.

“I’m going to wait where I can have more choices.”

Such hesitancy could pose public health challenges to Canada reaching the vaccination coverage needed to build protective immunity against COVID-19, said Hwang.

He noted that Germany has seen a reported preference among some for the vaccine made by Germany’s BioNTech with Pfizer, as well as a misconception that the AstraZeneca vaccine is inferior because of a lower efficacy rate.

Hwang says efficacy between vaccines cannot be compared because each involved completely different trials at different time periods, in different countries, with different volunteers of different age groups and varying trial designs.

“Until we have direct comparison studies where we give people one vaccine versus another and directly compare, it’s very difficult to know for sure how it’s going to pan out,” he says.

Then there’s the fact Canada’s initial AstraZeneca doses will be made at the Serum Institute of India, which dubs its version CoviShield, while later packages will be produced at the drug giant’s own manufacturing facilities.

Hwang acknowledges that could invite further scrutiny but says the Pune, India-based biotech firm has a “strong track record of producing vaccines.”

Sharma also stressed the similarities between the two shots Friday.

“For all intents and purposes they’re the same vaccine,” said Sharma.

“There are some slight differences in terms of manufacturing and the places that they are manufactured are different. The analogy is a bit like the recipe – so the recipe for the vaccine is the same, but they’re manufactured in different kitchens.”

US urges Tanzania to embrace COVID-19 vaccines, share data – Burnaby Now

Published

 on


NAIROBI, Kenya — The United States praised Tanzania on Friday for finally acknowledging the resurgence of COVID-19 after claiming for months it had defeated the pandemic through prayer. But the U.S. urged the country to share infection data and accept vaccines.

“It has become clear that the virus variant has arrived in Tanzania,“ U.S. Ambassador Donald Wright, who is also a doctor, said in a statement. “I’ve been encouraged by recent statements from the Ministry of Health acknowledging COVID-19 as a public health priority in Tanzania and urging citizens to take basic precautions.“

Tanzania is one of Africa’s most populous countries, with some 60 million people, and during its long COVID-19 denial the director of the Africa Centers for Disease Control and Prevention warned that if the continent isn’t united, “it’s doomed.”

High-profile deaths this month in the East African nation, including that of the vice-president of the semi-autonomous island region of Zanzibar, appeared to lead populist President John Magufuli to acknowledge publicly in the past week that COVID-19 was back.

For weeks, Tanzanians had seen a rise in death notices citing breathing difficulties and cases of what health workers called “pneumonia.” But countries such as Oman reported Tanzanians arriving in their countries and testing positive for the virus.

Meanwhile, Tanzania’s president openly questioned COVID-19 vaccines, without providing evidence. Tanzania is one of the very few countries in Africa that has not signed up for the global COVAX facility to provide vaccines to low- and middle-income countries. Now those vaccines have begun to arrive, in Ghana and Ivory Coast, with more on the way.

The U.S. ambassador’s statement urges Tanzania to “convene its health experts and review the evidence on vaccines.” He also notes “it is critical to collect and report information about testing and cases.“

Tanzania last updated its number of infections last April. That number remains at 509.

Then the ambassador turned to aid: “Here in Tanzania, we dedicated $16.4 million to mitigate the COVID-19 pandemic since the first confirmed case was diagnosed in March of 2020. The United States stands ready to ramp up our efforts and we are committed to working side by side with Tanzania to defeat COVID-19.”

An embassy spokesman did not immediately respond to a question about whether further aid depends on Tanzania sharing pandemic data and embracing vaccines.

Tanzania, unlike other African countries, did not lock down during the pandemic and it has promoted that to tourists and others.

In an interview with The Associated Press on Thursday, Tanzania’s investment minister, Kitila Mkumbo, asserted that COVID-19 “has not been one of the major concerns of investors.” He added that American investors “are waiting for the pandemic to slow down so movement can begin.”

And the minister welcomed the Biden administration, saying he believed that the U.S. will once again “take global responsibility of supporting developing countries like Tanzania in many aspects, like health.”

Vaccine centers embrace stickers and selfie stations – The Verge

Published

 on


The best picture I’ve seen this week was a selfie from my father-in-law who just got his first dose of a COVID-19 vaccine. Along with the shot, they gave him a sticker that says “I got vaccinated!”

As the vaccine rollout continues, clinics and distribution centers across the country are embracing things like stickers and even selfie stations decked out with colorful backgrounds to help people celebrate getting the shot.

The selfie stations are set up as colorful backgrounds, often with pro-vaccine messaging tiled with the name of the healthcare provider. It’s good branding. And hey, if social media-friendly backgrounds helped make some trendy restaurants popular, there’s no reason they couldn’t work for vaccine sites too.

Added bonus — if the vaccines are being given in a healthcare setting, it gives people a designated space to take pictures without compromising other patients’ privacy.

Vaccine stickers and selfies can increase confidence in vaccines. Just like “I voted” stickers were designed to remind people about Election Day, “I got vaccinated” stickers are designed to help people see the vaccination efforts unfolding in their own community.

Back in December, the Centers for Disease Control and Prevention developed stickers for healthcare workers to wear after they got vaccinated. Since they were some of the first people in the country to get vaccinated, the stickers were an easy way for workers to start conversations about the vaccines with their patients and colleagues — some of whom might be reluctant to get the vaccine.

The ready-made vaccination celebrations are also a way to dissuade people from sharing their vaccine cards on social media. Those can contain personal information, and posting photos of them can help scammers scam. A photo of your vaccinated self sporting a sticker, on the other hand, does not pose nearly as much of a privacy risk.

Stickers can serve the same purpose outside of the healthcare industry too. But also; they’re super fun. Slapping on a sticker is a chance to visually celebrate in a time when there’s been so little for us to enjoy. So is taking a selfie to share with the world. Sure, there are public health benefits to making vaccination visible. It’s also pure joy.

I’m not eligible to receive the vaccine yet where I am, and I probably won’t be for a long time. But after seeing so much death and suffering during the past year, it brings me nothing but hope and happiness to see the relief in people’s eyes after they get their shot.

Other people have been taking their vaccine celebrations into their own hands. Not content with the official offerings, they’re dressing in their best, donning sequins, and even bringing fun bandages to patch themselves up after the shot. Vaccinated people can’t throw a big maskless party yet — but they can celebrate a small, momentous victory. It’s fantastic.

There are still too few people vaccinated, here in the US and around the world. The rollout has been messy, and frustrating and inequitable. It still is. Governments can still do much better. But more people are getting the shot every day. In fact, Friday set vaccination records in the US and EU.

Without a doubt, that’s something to celebrate.

Here’s what else happened this week.

The growing evidence that the COVID-19 vaccines can reduce transmission, explained
When they were testing vaccines, companies looked to see if the vaccines could keep people from getting sick. And all authorized vaccines do a great job at keeping people out of the hospital and alive. But the big clinical trials weren’t designed to look at how well they can keep people from passing the disease from one person to another. It’s a big question, and one that researchers (and everyone else) is eager to uncover. (Kelsey Piper / Vox)

Perspectives

In every volunteer opportunity I’d ever been a part of, you made camp friends, formed quick alliances. To do so that day, when you even didn’t know who had been vaccinated and who hadn’t, felt aggressive and dangerous. Even holding the door open for the person behind you on the orientation tour could violate the required distance. I couldn’t discreetly murmur to my shift buddy about who was trying to cut and who was about to get out of hand.

More than Numbers

To the more than 113,507,393 people worldwide who have tested positive, may your road to recovery be smooth.

To the families and friends of the 2,519,257 people who have died worldwide — 510,467 of those in the US — your loved ones are not forgotten.

Stay safe, everyone.
