Plant-based meat is generally a better option than conventional beef for heart health, but it comes with trade-offs that make “healthy” a complicated label. These products match beef in protein content and add fiber that meat lacks entirely, yet they also pack significantly more sodium and can contain more saturated fat than you’d expect from something plant-derived.
How It Compares to Beef Nutritionally
The protein content is essentially a wash. An Impossible Burger and an 80/20 ground beef patty both deliver 19 grams of protein per serving. Where they diverge is in everything else.
Plant-based burgers contain fiber, which traditional meat does not. That’s actually the single clearest nutritional advantage, according to researchers at Ohio State University who compared the two side by side. Fiber supports digestion, helps regulate blood sugar, and is a nutrient most people don’t get enough of.
The saturated fat picture is more surprising. Many plant-based meats use coconut oil to mimic the richness of beef fat. Coconut oil is about 80% saturated fat, compared to 50% in beef fat. So depending on the product, you could be getting a comparable or even higher dose of saturated fat from a plant-based patty than from a beef one. Sodium is another weak spot: the Impossible Burger contains 370 mg per serving, compared to just 55 mg in a plain beef patty. That’s nearly seven times more.
Heart Health and Cholesterol
Despite the sodium and saturated fat concerns, clinical evidence suggests plant-based meat still comes out ahead for cardiovascular health. A Stanford Medicine crossover trial called SWAP-MEAT had participants alternate between periods of eating animal meat and plant-based meat. During the plant-based phase, LDL cholesterol (the type linked to heart disease) dropped significantly. So did TMAO, a compound produced during digestion of animal protein that’s associated with increased cardiovascular risk. Participants also lost weight during the plant-based phase.
These results suggest that even with its imperfections, plant-based meat creates a more favorable metabolic environment than conventional beef. The absence of animal-derived saturated fat and cholesterol likely plays a role, along with the presence of polyunsaturated fats and fiber that beef simply doesn’t offer.
The Ultra-Processed Label
Plant-based meats are, by definition, ultra-processed foods. They’re assembled from isolated proteins, oils, starches, flavoring agents, and binding ingredients. That classification has raised alarms, since ultra-processed foods as a category are linked to poorer health outcomes in large population studies.
But nutrition researchers at Harvard have pushed back on applying that label too broadly. Not all ultra-processed foods are created equal. Chips and soda are ultra-processed, and so is a plant-based burger, but their nutritional profiles are wildly different. Harvard experts have noted that when it comes to burgers specifically, plant-based patties remain a better choice than beef for both personal and planetary health. As one researcher put it, the fat composition of beef is so unfavorable that it’s “very easy to be better than that.”
The processing itself isn’t necessarily the problem. The question is what ends up in the final product.
Is the “Heme” Ingredient Safe?
Impossible Foods uses soy leghemoglobin, a protein derived from soybean roots, to give its burger a meaty, slightly bloody flavor. This ingredient has drawn scrutiny because it’s relatively novel. The FDA reviewed Impossible Foods’ safety data and had “no questions” about the company’s conclusion that it’s safe for consumption. Testing showed soy leghemoglobin is non-mutagenic, breaks down normally during digestion, and shares no structural similarity with known allergens or toxins. Oral toxicity studies in animals found no harmful effects even at high doses. The one caveat: it’s derived from soy, so it requires allergen labeling for people with soy sensitivities.
Nutrients You Might Miss
Whole animal foods contain hundreds of bioactive compounds beyond the basics listed on a nutrition label. Iron and zinc from meat are more readily absorbed by the body than the forms found in plants. Vitamin B12, which is critical for nerve function and blood cell production, occurs naturally in animal products but must be added to plant-based alternatives. Assembling isolated plant proteins, fats, and added vitamins doesn’t fully replicate the nutritional complexity of whole foods in either direction, whether that’s a cut of meat or a serving of whole legumes.
This matters most for people who rely heavily on plant-based meats as their primary protein source rather than treating them as one component of a varied diet. A black bean burger you make at home from whole ingredients will deliver a different, and in some ways richer, nutrient profile than a highly engineered commercial patty.
What to Look for on the Label
Not all plant-based meats are nutritionally equivalent. Sodium content across products ranges enormously, from as little as 1 mg per 100 grams in plain tofu to 2,000 mg per 100 grams in some plant-based mince products. A reasonable target is 150 to 250 mg of sodium per 100 grams. For saturated fat, look for products where saturated fat makes up less than a third of the total fat content. That’s a practical threshold for avoiding the coconut-oil-heavy formulations that undercut the heart health advantage.
Protein should be comparable to what you’d get from meat, in the range of 15 to 20 grams per serving. Products built on whole legume or pea protein bases tend to score better on fiber and micronutrients than those relying heavily on isolated soy or wheat protein concentrates.
Environmental Benefits Are Real but Nuanced
Life-cycle analyses show that products like the Beyond Burger and Impossible Burger generate roughly 3.2 to 3.5 kg of CO2 equivalent emissions per kilogram of product. Feedlot-finished beef ranges from 10.2 to 48.5 kg CO2 equivalent per kilogram, depending on the production system and what stages of the supply chain are counted. That’s a substantial difference.
The picture gets more complicated when you factor in well-managed grazing systems, where cattle raised on pasture can offset their greenhouse gas emissions through carbon sequestration in the soil. Some of these operations fix as much carbon as they emit, or more. When environmental footprints are also adjusted for nutrient density (accounting for how efficiently a food delivers iron, zinc, B12, and complete amino acids), the gap between animal and plant-based products narrows. For most consumers buying conventional grocery store beef, though, plant-based alternatives carry a meaningfully smaller environmental footprint.
