The Impossible Burger is a plant-based meat alternative designed to mimic the taste and texture of ground beef [1], [17]. It's made primarily from soy protein, coconut oil, sunflower oil, and heme, a molecule that gives it a meat-like flavor [47], [17].
A plant-based patty intended to replicate the sensory experience of eating a ground beef burger [1], [18]. It utilizes genetically engineered yeast to produce soy leghemoglobin (heme), contributing to its meat-like taste and appearance [17], [1].
Burgers
Ground beef substitute in various recipes (e.g., tacos, pasta sauces) [2]
Impossible Foods partners with the Food Innovation Center at Rutgers University to develop the Impossible Burger [17], [18].
The first Impossible Burger debuts in Manhattan at David Chang’s Momofuku Nishi restaurant [25].
Impossible Foods receives a "no questions" letter from the FDA regarding the safety of soy leghemoglobin [27].
Impossible Foods receives FDA approval for use of soy leghemoglobin as a color additive [28].
Replacing meat consumption with plant-based meat alternatives can lead to significant reductions in LDL-cholesterol, total cholesterol, and body weight [5].
Plant-based meats may have a lower potential cancer risk compared to conventional meat [8].
Some studies indicate that plant-based meat alternatives may promote gut dysbiosis and oxidative stress in the intestine [14].
The substitution of processed meat with nuts, legumes, and whole grains is associated with a lower risk of cardiovascular diseases [6].
Evaluating Potential Risks of Food Allergy and Toxicity of Soy Leghemoglobin Expressed in Pichia pastoris
Foods containing recombinant soy LegHb produced in Pichia sp. are unlikely to present an unacceptable risk of allergenicity or toxicity to consumers [1].
Plant-based meat alternatives and cardiometabolic health: a systematic review and meta-analysis
The substitution of PBMAs for meat was associated with significant reductions in LDL-cholesterol, total cholesterol, and body weight [5].
Gastrointestinal fate of proteins from commercial plant-based meat analogs: Silent passage through the stomach, oxidative stress in intestine, and gut dysbiosis in Wistar rats
Diets based on PBMAs showed lower protein digestibility than those containing meat and promoted an intense luminal glycoxidative stress and an inflammatory intestinal response [14].
Assessing the effects of alternative plant-based meats v. animal meats on biomarkers of inflammation: a secondary analysis of the SWAP-MEAT randomized crossover trial
Alternative plant-based meats do not significantly increase biomarkers of inflammation compared to animal meats [13].
Generally recognized as safe (GRAS) by the FDA for its intended use, though some concerns exist regarding potential allergenicity and the long-term effects of soy leghemoglobin [2], [1].
While some studies suggest potential benefits of plant-based meat alternatives, such as improved cholesterol levels and weight management, others raise concerns about processing, potential allergens, and gut health impacts. More research is needed to fully understand the long-term health effects [5], [14].
Veggie burgers made from whole foods (beans, vegetables, grains)
Offer a less processed alternative with more fiber and potentially fewer additives [20].
Where to find: Homemade or in the frozen section of most supermarkets [Source 20].
Salmon burgers
Provide heart-healthy omega-3 fatty acids [20].
Where to find: Frozen or fresh in most supermarkets [Source 20].
Seitan, tofu, mushrooms, eggplant, tempeh
Less processed and can be seasoned to mimic meat flavors [42].
