Should You Trade In Your Beef Burger for a Bloody Plant-Based Impossible Burger?

The mouthwatering plant-based Impossible Whopper. How does it stack up against the original Whopper?

Impossible Foods wants you to trade in your beef burger for a plant-based burger and aspires to make your transition seamless. Unlike its plant-based peers, the Impossible Burger ‘bleeds’, cooks, and smells like meat thanks to its secret ingredient, heme.

Should you make the switch? Can meat lovers have their cake and eat it too?

Since its exclusive launch through top chefs (such as Chef David Chang at Momofuku Nishi) and boutique burger chains such as Umami burger, the Impossible Burger has gone mainstream. Impossible Foods is one of several plant-based burger companies fuelling a plant-based fast-food feeding frenzy, at chains such as White Castle (Impossible Slider), A&W (Beyond Meat) and Burger King (Impossible Whopper).

With such wide reach, it’s a great time to ask yourself whether you should make the switch. The answer, it turns out, depends on what you care about.

Impossible Foods, and many other companies offering plant-based meat alternatives, have their roots in environmental and ethical motivations. The impact numbers reflect these priorities.

This table shows the resources needed to produce Impossible burgers versus beef burgers (per kilogram). Impossible’s patties require far fewer resources across the board, with figures ranging from 87% reduction water consumption to 96% reduction in land occupation.

Given that Americans alone consume 14 billion burgers per year, if only one in ten people make the switch, we would see 1.4 billion times the impact numbers above.

McDonalds alone goes through about 70,000,000 pounds of beef per year, or approximately 190,000 pounds of beef daily. We’re talking hundreds of thousands of cows sacrificed in the name of burgers.

The nutritional profile of the Impossible Burger patty is remarkably similar to that of Burger King’s beef Whopper patty. The burgers become even more similar when you pile on the sauces and the bun.

Patty A – the plant-derived patty – can be identified by its hint of fiber and lack of cholesterol, because these are unique to plants and animals respectively. Notably, the nutritional profile of the Impossible burger patty is unlike that of any whole plant, (especially when you layer on sauces and a white bun).

The table below summarizes the main nutritional differences:

Are these relatively minor differences likely to make the plant-version better for your health? Perhaps… but only if you swap beef vs plant burgers daily, and even then, the differences would be marginal given the whole package (sauces and bun).

The reality is that we don’t fully understand why greater intake of whole plants tends to be associated with better health outcomes (see Harvard Health summary). We suspect it’s a combination of factors including: high fiber and water content, low levels of saturated fats (with some exceptions), moderate protein content, and high levels of phytochemicals such as antioxidants. Unfortunately, many processed plant-based foods don’t offer these same benefits.

Public health outcomes are another consideration, and may favour a plant based choice.

Given the animal-based origins of many food-borne diseases, a shrinking animal livestock industry could lead to fewer outbreaks. Similarly, a shift away from beef (and other livestock) could help stem the rising tide of antibiotic-resistant bacteria, by reducing the contribution of animals (that are routinely fed antibiotics). In addition, eating charred meats has been linked to increased risk for certain cancers (read more at cancer.gov)

Last but not least, comes taste.

Impossible’s burger appears to be the most realistic plant-based burger on the market. My unscientific survey of friends and family supports this view, as does Burger King’s April Fool’s Day video and Impossible Foods’ extensive market testing and many awards. Yet, tastes are personal and some people reject even subtle differences from their trusty favourites. On the flipside, for some plant-based eaters, the similarity to beef is not necessarily a good thing.

The bottom line is that trading in beef burgers for plant-based burgers is a big win on the environmental and animal suffering fronts, but may not move the needle on the health front.

Given this scorecard, I hope that omnivores will try making the swap, and find it to be seamless and delicious. As for those who are already plant-based, I hope that you won’t see the increasing availability of vegan fast food as a reason to eat more of it. The odd fast-food indulgence is harmless, but should be seen for what it is — an indulgence.

Congratulations, Impossible Foods on taking this giant step towards your lofty mission!
