Is an Impossible Burger healthy for you?: A Nutritional Breakdown

According to a 2019 Nielsen report, 39% of Americans were actively trying to eat more plant-based foods, prompting the rise of meat alternatives like the Impossible Burger. But beyond its environmental benefits, the crucial question remains: Is an Impossible Burger healthy for you?

Quick Summary

The Impossible Burger is a processed plant-based meat alternative with comparable protein to beef but with more sodium and added saturated fat, often from coconut oil. While it offers benefits like no cholesterol and added fiber, it should not be mistaken for a whole-food vegetable patty.

Key Points

Nutritionally Comparable to Beef: A 4oz Impossible Burger patty has a similar amount of protein and saturated fat as an 80/20 beef burger, though it is lower in total fat and calories.
No Cholesterol, Plus Fiber: A key advantage is the absence of cholesterol, which is a major concern with beef consumption, along with the added benefit of dietary fiber.
High in Sodium: The Impossible Burger contains significantly more sodium than an unseasoned beef patty, making it a less healthy option for individuals on low-sodium diets.
Processed Plant-Based Ingredients: It is a highly processed product, incorporating soy protein concentrate, coconut oil, and a genetically engineered heme, which differentiates it from whole-food plant patties.
Environmental Benefits: Choosing an Impossible Burger offers a substantial environmental benefit, requiring less land, water, and producing fewer greenhouse gases compared to industrial beef production.
Context is Key: Its healthfulness depends on the comparison—it may be a better option than a high-fat beef burger but is not as healthy as a simple, unprocessed vegetable patty.

Understanding the Impossible Burger's Nutritional Profile

When considering if an Impossible Burger is a healthy choice, it is essential to look at its nutritional composition, which differs significantly from both a traditional beef burger and a whole-food veggie patty. The Impossible Burger is designed to replicate the taste and texture of beef, and its nutritional values reflect that goal, sometimes leading to similar saturated fat content. However, as a plant-based product, it also boasts some distinct advantages, such as containing zero cholesterol and providing dietary fiber.

A standard 4-ounce Impossible Burger patty is fortified with essential vitamins and minerals, including B vitamins (B1, B2, B3, B6, B12), iron, zinc, and calcium. The presence of vitamin B12 is particularly beneficial for those on a vegan diet, as this nutrient is typically found in animal products. The primary source of protein is soy protein concentrate, providing a solid 19 grams per serving. Unlike beef, it also contains dietary fiber, which is important for digestive health.

The Ingredients and Processing Debate

The healthfulness of the Impossible Burger is a subject of debate, largely due to its highly processed nature. Its ingredients are a carefully engineered blend designed to mimic the sensory experience of cooking and eating meat. The key components include:

Soy Protein Concentrate and Isolate: Provides the protein and texture.
Coconut Oil and Sunflower Oil: Adds fat for juiciness and sizzling on the griddle. The high saturated fat content of coconut oil is a point of concern for some health experts, as it can raise LDL (“bad”) cholesterol levels.
Soy Leghemoglobin (Heme): The 'magic' ingredient produced via genetically engineered yeast, this molecule gives the Impossible Burger its red color, meaty flavor, and sizzle. While the FDA has approved its use, some critics have raised questions about its long-term health effects.
Methylcellulose: A binder made from chemically treated vegetable cellulose to hold the patty together.

Critics argue that despite being plant-based, the heavy processing makes the Impossible Burger nutritionally inferior to whole-food plant sources like beans or lentils. In contrast, supporters point out that comparing a plant-based burger to a salad is not the right comparison, as its purpose is to replace an animal product, not a whole vegetable meal. They emphasize that it contains no animal hormones or antibiotics and is a more sustainable option.

Comparison: Impossible Burger vs. Beef Burger

For consumers, the most common question is how the Impossible Burger stacks up against a conventional beef patty. A comparison reveals a mixed bag of nutritional trade-offs. The following table compares a standard 4-ounce Impossible Burger to an 80/20 ground beef patty:


Nutrient	Impossible Burger (4oz)	80/20 Ground Beef (4oz)	Key Difference
Calories	230 kcal	290 kcal	Lower calories
Total Fat	13g	23g	Significantly lower
Saturated Fat	6g	8g	Lower
Cholesterol	0mg	80mg	None
Sodium	370mg	75mg (raw)	Significantly higher*
Carbohydrate	9g	0g	Higher (contains fiber)
Dietary Fiber	5g	0g	Contains fiber
Protein	19g	19g	Comparable

*Note: Sodium content of beef often increases during cooking due to added salt, making the final difference potentially less dramatic.

The trade-offs are clear: you eliminate cholesterol and gain fiber, but you take on a much higher sodium load and are still consuming a significant amount of saturated fat, albeit slightly less than 80/20 beef. For those monitoring sodium intake, the Impossible Burger could be a poor choice, especially when consumed as part of a restaurant meal with additional high-sodium ingredients like buns and condiments.

When is an Impossible Burger a Good Choice?

An Impossible Burger can be a good choice for several reasons, though it's important to keep context in mind:

For environmental reasons: For many, the primary motivation for choosing an Impossible Burger is its significantly lower environmental impact. It requires less land and water and produces fewer greenhouse gas emissions than beef from cows.
For meat reducers: For committed meat-eaters or 'flexitarians' looking to reduce their consumption of animal products, the Impossible Burger offers a familiar and satisfying alternative that can help them transition to a more plant-based diet.
For specific dietary needs: As it contains no animal products, it's suitable for vegetarians and vegans. It is also free of animal hormones and antibiotics.

Making the Impossible Burger Healthier

For those who choose the Impossible Burger, there are several ways to boost its nutritional value and mitigate some of its downsides:

Build a healthier burger: Instead of a processed white bun, opt for a whole-wheat bun to increase fiber intake.
Add plenty of vegetables: Load up on fresh vegetables as toppings, such as lettuce, tomato, onion, and avocado, to add vitamins, minerals, and fiber.
Control the sodium: When cooking at home, minimize or eliminate added salt. Be mindful of high-sodium condiments like ketchup and pickles.
Consider portion size: Stick to a single patty and avoid adding high-fat cheese or bacon alternatives.

Conclusion

So, is an Impossible Burger healthy for you? The answer is nuanced and depends on the comparison. It is a highly processed product with high sodium and a considerable amount of saturated fat, which means it should not be considered a 'health food' in the same way that a simple black bean or mushroom patty would be. However, compared to a higher-fat 80/20 beef burger, it offers less total and saturated fat and zero cholesterol, plus valuable fiber and fortified vitamins. Ultimately, for someone who frequently eats beef and is looking for a satisfying, sustainable alternative to reduce animal product consumption, the Impossible Burger can be a beneficial choice when consumed in moderation. For those prioritizing whole, unprocessed foods, healthier plant-based options are available.
