About The Impossible Burger

The Impossible Burger is a processed, plant-based burger that has been designed especially to taste like meat. After its release, the Impossible Burger quickly became a huge favorite amongst vegetarians and vegans due to its particularly realistic taste and texture. 

How Is The Impossible Burger Made? 

Generally speaking, before the Impossible Burger came along, most vegetarian and vegan ‘burgers’ were made using beans, soy, grains, and/or mushrooms.

The producers of the Impossible Burger significantly diverted from these traditional ingredients. 

Instead, to create the Impossible Burger, ingredients such as soy protein concentrate, coconut oil, sunflower oil, potato protein, yeast extract, methylcellulose, gums, salt, and water were used. 

Additionally, many useful vitamins and minerals are also added to the Impossible Burger. For instance, it includes vitamin B12 (which is particularly important for vegans and vegetarians, vitamin B6, thiamin, and niacin. 

However, the standout ingredient that makes the Impossible Burger what it is is heme. Heme is a compound that contains iron.

Usually, it comes from animal products, but the manufacturers of the Impossible Burger used soy-based heme that is derived from yeast.

More specifically, to produce heme, DNA is extracted from the roots of soy plants. Then, this is inserted into genetically engineered yeast.

Following, that yeast is fermented. Once this process has been completed, you get heme! This makes the burger taste similar to beef.

How To Cook The Impossible Burger

In short, yes! You can cook the Impossible Burger using the same methods that you would when cooking a regular beef burger.

Pros Of The Impossible Burger 

So, apart from being a delicious plant-based alternative to juicy meat burgers, you’re likely wondering, are there any benefits associated with eating the Impossible Burger?

Well, yes! Take a look at the best pros of the Impossible Burger below. 

High In Nutrients 

The Impossible Burger contains a great number of nutrients. As previously mentioned, some of the added nutrients in the Impossible Burger are particularly important for vegetarians and vegans. 

It has been found that vegans and vegetarians tend to be at a higher risk of certain nutrient and vitamin deficiencies than people who consume meat and other animal products.

As such, the added nutrients in the Impossible Burger work to keep such people healthier. 

Whilst many vegetarian and vegan products include extra vitamins and minerals, the Impossible Burger sets itself apart from others by using plant-based heme.

Heme is a great source of iron that is better absorbed by the body than non-heme iron.

In addition to being suitable for vegetarians, vegans, and other people who are eliminating meat-based products from their diets, the Impossible Burger is also gluten-free.

As such, it is a great option for a huge range of people – regardless of their deity requirements, allergies, or intolerances.

Cons Of The Impossible Burger 

As with all processed foods, there are unfortunately some drawbacks to the Impossible Burger. To learn more about them so that you can make the most informed dietary choices possible, take a look at the sections below. 

Plant-Based Heme

Despite its many advantages, there are some concerns regarding plant-based heme. It has been deemed safe by the FDA, however, little is known about its long-term effects and safety. 

This is because current studies only tend to be conducted over short periods of time.

Whilst it is promising that these studies have shown plant-based heme to have no negative effects, more research is needed to confirm that it is safe for humans to consume over long periods. 

Allergenic Ingredients 

Whilst the Impossible Burger is a great option for gluten-free and dairy-free diets, it does contain some other ingredients that many people struggle to consume.

Specifically, it contains soy. Even though soy allergies are less common than gluten or dairy intolerances, it is still one of the eight most prevalent allergens amongst both adults and children. 


The Impossible Burger contains genetically modified ingredients. In fact, its main ingredients – plant-based heme and soy protein – have been genetically modified.

Whilst most scientists agree that GMO foods are safe, some are concerned about their use. 

Specifically, some scientists are concerned about GMO crops that have become resistant to common herbicides, including glyphosate.

Some studies have concluded that glyphosate could pose harm to humans and animals as it can harm hormonal function. 

Is The Impossible Burger Keto-Friendly? 

Now that you’re equipped with all of the information regarding the Impossible Burger, you’re likely wondering, is it keto-friendly? Well, the answer is a little bit more complicated than you might have expected. 

When looking at the nutritional information of the Impossible Burger, it seems as though it is very keto-friendly. With only 6 grams of net carbs, this burger should be easy to incorporate into a keto diet. 

However, as previously discussed, the Impossible Burger is very processed. It also contains GMOs. These are two big no-nos when it comes to the keto diet. As such, if you follow a strict keto diet, you should steer clear of the Impossible Burger. 

In fact, the Impossible Burger also contains other non-keto-friendly ingredients. For example, sunflower oil, cultured dextrose, and modified food starch should be eliminated or limited as much as possible when you are following a keto diet. 

Although, it is worth mentioning that following a keto diet when you have additional diet restrictions or preferences can be tricky.

As such, if you want to incorporate the Impossible Burger into your diet so that you can enjoy a treat every now and then, feel free to do so.
