Canadians can't get enough of Beyond Meat's plant-based burger that's designed to taste just like beef.

It has attracted not only vegetarians but also meat eaters such as Jim Allen, who recently dined on a Beyond Burger at A&W, believing it was the healthier choice.

"I was quite eager to try it," said Allen, who lives in Toronto. "Everybody's saying get away from red meat and eat more plants."

Canada's new food guide advises Canadians to consume less meat and eat more healthy plant-based protein foods such as beans and lentils.

But does Beyond's burger qualify as a healthy protein alternative?

Beyond Meat says yes. On its website, the California-based company markets its plant-based products as "better for you" options that don't come with the major health risks associated with certain kinds of meat.

However, nutrition experts CBC News interviewed argue that there's no hard scientific data — at least not yet — to show that a processed plant-based patty trumps beef.

"Where is their research saying that — that this is better than eating a small, portion-controlled, lean piece of meat?" said Toronto-based dietitian and nutritionist Rosie Schwartz.

The Beyond Burger contains close to 20 ingredients, including refined coconut oil, pea protein isolate and flavouring. Schwartz says that qualifies it as a highly processed food — something that Canadians are advised to limit in their diet, along with processed and fatty meat.

"When Health Canada says we should be choosing more plant-based protein alternatives, I believe they're talking about whole foods. They're not talking about ultra-processed foods," said Schwartz.

Beyond Meat CEO weighs in

Food scientist Ben Bohrer says when comparing a Beyond Burger with beef, the nutritional composition is fairly similar.

A Beyond patty contains 270 calories, five grams of saturated fat and 390 milligrams of sodium. In comparison, Walmart's Great Value Beef Burger has 30 fewer calories and two more grams of saturated fat. It also has 300 mg less sodium, but it's not pre-seasoned like the Beyond patty.

"They try to match ground beef as closely as they can," said Bohrer, a professor at the University of Guelph. "If you're doing that, then I don't know how you could say that there's advantages to the product that you've made."

Beyond Meat CEO Ethan Brown argues such comparisons are too simplistic because they don't factor in the reported health risks — such as cancer and heart disease — that are associated with eating red and processed meat.

"The media has an obligation to get this stuff right," said Brown in a phone interview. "If consumers are reading these [news] pieces, and going away thinking they just as well might be eating red meat, that's not fair to them."

As proof, Beyond Meat sent CBC News information on numerous health studies looking at the implications of eating meat.

Research lacking

The most recent study the company pointed to was published in June by the Harvard T.H. Chan School of Public Health. It found that upping one's red meat intake — processed red meat, in particular — increased the risk of premature death.

"I'm imploring people to please do their research," said Brown.

"The health implications of red and processed meat really stretch far beyond saturated fat levels."

Dr. Frank Hu, senior author of the Harvard study, says the research so far demonstrates that eating too much red meat, especially processed meat, can be harmful to one's health.

"Replacing red meat with other sources of protein, especially plant-based protein food, can reduce [the] risk of chronic disease and premature death," said Hu, a professor of nutrition and epidemiology at Harvard.

But he said we don't yet have research showing that a processed plant-based burger is a healthier food choice.

"Based on the data we have, we can make a prediction they're better," said Hu. "But this type of study hasn't been done yet to directly compare the health effects of the two types of burgers."

Beyond Meat, however, is sticking to its claims.

"Given the abundance of research clearly demonstrating the link between red and processed meat consumption and health risks, we stand firmly behind our belief that Beyond Meat products are an improvement nutritionally," Dariush Ajami, Beyond Meat's chief innovation officer, said in an email.

He added that the Beyond burger also has the benefit of containing no cholesterol or animal-derived saturated fat, and is lower in saturated fat than burgers made from fattier cuts of beef.

As for customer Allen, he's decided that unless new research tells him otherwise, he'll continue to presume that Beyond's plant-based burger is healthier. However, he doesn't plan to purchase it again at a fast-food restaurant. That's because he discovered that once the bun and toppings are added, A&W's version has 1,110 milligrams of sodium.

"I'm disappointed," said Allen, who's trying to cut down his sodium intake.

Health Canada recommends that adults aim for about 1,500 mg of sodium daily and not exceed 2,300 mg.

A&W told CBC News that customers can modify their burger to suit their dietary needs, such as swapping the bun for a lettuce wrap.
