Impossible vs Beyond Burger: Which Is Actually Healthy?

The Short Answer

The Beyond Burger IV (the newest version with avocado oil) is the healthier choice.

In a massive 2024 reformulation, Beyond Meat replaced inflammatory seed oils and high-saturated-fat coconut oil with avocado oil. This dropped the saturated fat content to just 2g per patty—significantly lower than beef. It is also Non-GMO Project Verified and free of soy and gluten.

Impossible Burger is the "tastier" mimic but the dirtier product. It relies on GMO soy protein, coconut oil (high saturated fat), and a genetically engineered ingredient called Soy Leghemoglobin (Heme) to make it "bleed." With 6-8g of saturated fat per serving, it poses similar heart-health risks to conventional fatty beef, without the whole-food benefits.

Why This Matters

Plant-based meats are often sold as "health foods," but they are ultra-processed products engineered in labs. Is Plant Meat Ultra Processed

For years, both brands were nutritional dead heats: high in sodium, high in saturated fat (from coconut oil), and highly processed. That changed with Beyond's "IV" update. By switching to avocado oil, Beyond effectively removed the biggest health criticism against plant burgers (high saturated fat), leaving Impossible behind in the "greasy but tasty" category.

If you are vegan for health reasons, Beyond is the clear winner. If you are vegan for ethical reasons but miss the specific taste of blood and iron, Impossible is the only one that replicates it.

What's Actually In Them

Beyond Burger IV (The "Clean" Reformulation)

The new recipe focuses on heart-healthy fats and simple proteins.

• Pea & Lentil Protein: The base structure. Non-GMO.
• Avocado Oil: The game-changer. Replaced canola/coconut. lowers saturated fat. Cooking Oils
• Methylcellulose: A plant-fiber binder (also found in laxatives) used to stick the meat together.
• Beet Juice: purely for color.

Impossible Burger (The "Tech" Burger)

Designed to fool carnivores, not necessarily to be healthy.

• Soy Protein Concentrate: Sourced from GMO soy. High heavy metal risk if not organic (it isn't).
• Coconut & Sunflower Oil: High in saturated fat and omega-6s.
• Soy Leghemoglobin (Heme): The controversial "magic" ingredient. It’s a protein produced by genetically engineered yeast fermentation. The FDA approved it, but consumer safety groups have fought it due to lack of long-term testing.
• Cultured Dextrose: A shelf-life extender (sugar-based preservative).

Nutritional Showdown

Here is how the 4oz patties compare to each other and 80/20 beef.

Key Takeaway: Beyond has 75% less saturated fat than Impossible. Impossible has more fiber, but also more carbs and sodium.

What to Look For

Green Flags (Beyond):

• "Made with Avocado Oil" sticker on the package.
• Non-GMO Project Verified seal.
• Soy-Free and Gluten-Free labels.

Red Flags (Impossible):

• "Bioengineered Food Ingredient" disclosure (required by law due to GMO heme/soy).
• High Saturated Fat: Check the % DV. Impossible hits ~40% of your daily limit in one patty.
• Glyphosate: Since Impossible uses conventional GMO soy, it likely contains glyphosate residues, though the company claims levels are safe.

The Bottom Line

1. Choose Beyond IV for Health. The switch to avocado oil makes it a genuinely heart-healthier alternative to beef. It cuts saturated fat dramatically while maintaining high protein.

2. Choose Impossible for Taste (Occasionally). If you specifically crave the "bloody" iron taste of red meat, Impossible wins on flavor. Treat it like a fast-food indulgence, not a health staple.

3. Watch the Sodium. Both burgers pack nearly 20% of your daily sodium before you even add a bun, cheese, or ketchup. If you have high blood pressure, stick to unprocessed Is Beef Healthy or lentils.

FAQ

Is the "Heme" in Impossible Burger safe?

The FDA says yes; some independent scientists say "we don't know yet." Heme (soy leghemoglobin) is new to the human food supply in this isolated, yeast-fermented form. While chemically similar to the heme in meat, there are no long-term studies on consuming this specific genetically engineered version.

Does Beyond Burger contain glyphosate?

No. Beyond Meat products are Non-GMO Project Verified, meaning they do not use the Roundup Ready crops (like GMO corn/soy) that are sprayed with glyphosate. Impossible Foods uses GMO soy, which is engineered specifically to survive glyphosate spraying.

Which one tastes more like real beef?

Impossible. The added Heme gives it a metallic, "bloody" flavor profile that mimics the iron in animal muscle. Beyond IV is "meatier" than previous versions but still tastes slightly nutty/earthy due to the pea protein base.
