The Impossible Burger

Plant-based eating is a growing trend, thanks to concerns about health, the environment, and animal welfare! Although the rate of veganism and vegetarianism is on the rise, the fastest growth is among people who eat a flexitarian diet, a sort of “part-time” vegetarian diet. Flexitarians strive to get more plant-based foods in their diet but still eat meat. They’re not ready to go completely plant-based but they’d like to get some benefits of doing so.

If there’s a sure sign that the flexitarian movement is growing, it’s the enthusiastic response to the debut of the Impossible Burger, a burger made with plant-based ingredients that actually “bleeds” when you bite into it. After trying the burger, some people couldn’t distinguish it from a hamburger made of beef. So, you can imagine the excitement when Burger King announced it will launch the Impossible Whopper, made with plant-based meat, nationwide by the end of the year. When they tested this plant-friendly burger in St. Louis, the response was so strong that the demand exceeded the supply, leaving the company wondering how they could keep up. Some restaurants already serve this burger, further putting strains on production.

The Impossible Burger seems to have captured the taste and texture of real meat to give meat lover and plant-based eaters a burger they can enjoy–but is the Impossible Burger and other plant-based meats a winner from a health standpoint?

Plant-Based Eating: Does It Lower Mortality?

Why is interest in plant-based eating growing? The evidence for eating more plants is strong and you don’t have to go vegan to get the benefits. This study of over 130,000 people found that replacing only 3% of meat-based calories with plant protein was associated with a lower risk of death. In fact, replacing processed red meat with plant protein was linked with a 34% reduction in mortality, and mortality shrunk by 12% when subjects substituted plants for unprocessed red meat.

Studies also link plant-based diets with a lower risk of chronic health problems. As Harvard Health points out, higher meat consumption, mainly processed meat, lamb, and pork, is associated with a greater risk of heart disease, stroke, and type 2 diabetes. So, replacing some meat with plants is a smart move for health!

But what about burgers like the Impossible Burger and other plant-based meats? How do they stack up from a health and nutrition perspective?

Plant-Based Burgers: What You Should Know

First, let’s look at the Impossible Burger, the burger making the news recently. What’s in it?

Here are the ingredients in the Impossible Burger:

Water, Soy Protein Concentrate, Coconut Oil, Sunflower Oil, Natural Flavors, and 2% or less of: Potato Protein, Methylcellulose, Yeast Extract, Cultured Dextrose, Food Starch Modified, Soy Leghemoglobin, Salt, Soy Protein Isolate, Mixed Tocopherols (Vitamin E), Zinc Gluconate, Thiamine Hydrochloride (Vitamin B1), Sodium Ascorbate (Vitamin C), Niacin, Pyridoxine Hydrochloride (Vitamin B6), Riboflavin (Vitamin B2), Vitamin B12.

As you can see, the main ingredient is soy protein concentrate, a processed form of soy. The soy leghemoglobin is a protein-rich, plant-based iron that makes the burger “bleed” when you bite into it. People who are trying to avoid genetically modified foods will probably steer clear of the Impossible Burger since soy leghemoglobin is made by mixing soy protein with genetically engineered yeast. Some people will argue that processed soy protein isn’t the healthiest way to get your protein. The burger originally contained wheat protein, but they switched to soy to make the burger gluten-free.

Although the calorie content is similar, the Impossible Burger contains 240 calories versus 260 for a similar-sized meat-based burger. However, the meat-based burger contains more protein. The Impossible Burger has 19 grams, whereas a meat-based burger has 28 grams. The Impossible Burger contains only 9 grams of carbs, so it should be blood-sugar friendly and contains 3 grams of fiber, whereas a beef burger contains none. It also contains added vitamins.

For people who eat meat to get enough iron, the Impossible Burger covers the bases. Research shows that the iron in the soy leghemoglobin in the Impossible Burger is as bioavailable to the body as the iron in meat. It’s similar to heme-based iron, the kind in meat.  Plus, the Impossible Burger contains vitamin B12, a vitamin vegans and vegetarians don’t get enough of.

Still, the Impossible Burger is processed and this is the case with many plant-based burgers you find in the frozen case. Most are not made with whole vegetables and legumes but are isolated components of plants and, usually, wheat or soy protein. So, plant-based burgers from the freezer case may be lacking the vitamins, minerals, and phytonutrients you get when you eat vegetables in their whole, unaltered state. Still, eating a plant-based burger, whether processed or not, gives you a break from eating processed meat and red meat, both of which are linked with higher mortality. So, eating an occasional plant-based burger when you’re in a hurry rather than ordering a hamburger at a drive-thru is a way to reduce your meat consumption.

Why Not Make Your Own?

What if you love plant-based burgers but want them to be as healthy as possible? If you have the time, making your own plant-based burgers at home is a good option. When you make them in your own kitchen, you control the ingredients. You can find plant-based burger recipes that combine beans, lentils, cooked whole grains, and a wealth of vegetables. Whip up a batch and freeze what you can’t use right away. You can vary your recipes for variety. The possibilities are endless! Find recipes from sites like Pinterest and modify them, if you’re like, to meet your own tastes.

The Bottom Line

The Impossible Burger could be the closest thing to a meat-free burger that actually tastes like meat. Enjoy it on occasion, but if you want to maximize the health benefits of a burger, make your own! Nothing tastes better than homemade and you have complete control over what goes into it.

  1. I would steer clear of fake meat if you are concerned about Glyphosate which is a known carcinogen and linked to 28 chronic diseases. Don’t use google to search it, Google has buried any website that is considered alternative and striving to educate people about pharmaceuticals, chemicals and corporate greed which pretty much depicts Bill Gates, GMA, Bayer/Monsanto/Cargill, etc. Replace Google search with DuckDuckGo and start with Impossible Burger and glyphosate. I am alarmed over what has happened to our freedom of information, we used to say this is the *information age*, its the dis-information age followed by fake everything. I also disagree with many of the statements made in this article about the health of vegans and vegetarians. That diet may work until you get to be about age 30. Its also a huge negative to unborn children. No way is a vegan pregnant mother going to be able to supply K-2 and many other necessary nutrients to their baby, because you cannot get them from any other source but animal based. The facts are buried in the money trail. This is the same theme that has caused a huge trail of unhealthy people later in life, that is….cholesterol causes heart disease. It has been debunked in recent years and proven that fats are crucial for brain health. Think people, why are there so many people with Alzheimer’s, and mental decline as they age, along with chronic diseases in the younger age groups, starting at 40. The most incredible statistic I’ve read lately (Chris Kresser) that the health of adults begins to plummet at age 30! Not by a little, but quite a drop. Highly processed fake meat is not healthy and will never be a replacement for grass-fed, humanely raised, beef, lamb, etc., and wild caught fish along with organic farming. I know what I wrote will largely be ignored, maybe even erased, but the cycle of healthy farm land includes animals.

  2. Thanks for posting this article. I am allergic to yeast so avoid burgers with buns but sometimes have burger patties. This meatless version not only contains yeast extract but also the soy leghemoglobin is processed with yeast so this burger is probably more toxic to me than a meat based burger and I will definitely be avoiding it. If you are eating highly processed food with lots of chemical additives it isn’t going to be good for you regardless of whether it is meat based or plant based. And by the way those burger buns are also highly processed and full of chemical additives.

  3. I actually ate the Impossible Burger at Carl’s Jr. when I was visiting my family in San Diego. When you want to eat a burger with your family and there isn’t any meatless choices, but this I think at least they are going in the right direction. Yes, I did eat it on bread, mayo and cheese, which if you want to be healthier you need to eliminate. I do agree soy is not good. They need to get rid of soy. But, the burger did taste good and had a beefy after taste. But, I wouldn’t eat it everyday!
