What is Just Egg Made Of?
Unlike traditional eggs, which are a single ingredient product, Just Egg is a processed food made from a blend of ingredients designed to mimic the taste, texture, and cooking properties of chicken eggs. Its primary protein source is mung bean protein isolate. Mung beans are a legume cultivated for thousands of years, and the company discovered that their protein has the unique ability to gel and coagulate like an egg when cooked.
To achieve the right color and texture, Just Egg also includes other components. Expeller-pressed canola oil provides fat for richness and mouthfeel, while natural turmeric and carrot extractives contribute to the classic yellow hue. Other ingredients like gellan gum and tetrasodium pyrophosphate function as stabilizers and emulsifiers, ensuring the liquid stays homogenous. It's also worth noting that the product contains soy lecithin, which acts as another emulsifier. All these components are necessary to replicate the complex cooking chemistry of a chicken egg using plant-based ingredients.
The Mung Bean: Just Egg's Protein Source
The mung bean is the nutritional hero of Just Egg. As a member of the legume family, mung beans are a natural source of protein. While the protein content of legumes is well-regarded, their amino acid profile can differ from animal proteins. A significant difference is that animal proteins, including chicken eggs, are typically considered 'complete' proteins, containing all nine essential amino acids in sufficient quantities. Plant-based proteins can sometimes be incomplete, meaning they lack or have limited amounts of certain essential amino acids. However, many plant-based eaters can achieve a complete amino acid profile throughout the day by consuming a variety of different protein sources. The protein in Just Egg is specifically isolated to provide structure and a protein boost, but it is important for those on a strict vegan diet to consume a diverse range of plant proteins to ensure all essential amino acids are covered.
Just Egg Protein Content vs. Chicken Egg
Comparing Just Egg to a traditional chicken egg reveals some key differences, particularly regarding protein content and overall nutritional profile. The protein levels are quite comparable, but the source and accompanying nutrients vary widely.
| Nutrient | Just Egg (3 tbsp liquid) | Large Chicken Egg |
|---|---|---|
| Protein | 5g | 6g |
| Cholesterol | 0mg | 207mg |
| Total Fat | 4g | 5g |
| Saturated Fat | 0g | 1.5g |
| Sodium | 210mg | 65mg |
| Carbohydrates | 0g | 0.5g |
| Vitamin D | 0% Daily Value | ~5% Daily Value |
| Vitamin B12 | 0% Daily Value | Excellent source |
The comparison table clearly illustrates that while Just Egg holds its own in protein quantity, it is significantly different in its other nutritional components. For example, Just Egg has no cholesterol, which is a major draw for individuals seeking to reduce their intake, as is the case for many on a vegan diet. However, this also means it lacks some key micronutrients naturally present in chicken eggs, such as Vitamin D and B12. The sodium content is also notably higher in Just Egg.
Beyond Protein: A Full Nutritional Picture
While Just Egg's protein is a central talking point, its overall nutritional profile deserves a comprehensive look. It is an ultra-processed food, meaning it contains multiple ingredients beyond its primary mung bean source. Some people may prefer less-processed options, but for those seeking a quick and easy-to-use egg substitute, this processing is what makes the product so convenient and functional. The lack of certain vitamins and minerals found naturally in chicken eggs, like choline and B vitamins, can be addressed through other dietary sources or supplements.
Just Egg's zero cholesterol content is a huge advantage for many, particularly those with concerns about cardiovascular health or those who follow a vegan diet. It's a trade-off: gain a cholesterol-free, plant-based alternative with comparable protein, but lose some of the naturally occurring vitamins and minerals found in a chicken egg. It is important for consumers to be aware of these differences and make dietary choices based on their individual health goals.
Is Just Egg the Right Choice for You?
The decision to use Just Egg often comes down to dietary needs and personal preferences. For vegans, those with egg allergies, or anyone looking to reduce their cholesterol intake, Just Egg is an excellent choice. It provides a familiar, convenient option for making scrambled 'eggs', omelets, and French toast while sticking to a plant-based diet. The product's consistent performance also makes it a reliable culinary ingredient. For those whose main priority is protein, it's a solid contender, providing similar grams of protein per serving as a traditional egg. On the other hand, someone focused on maximizing micronutrient intake from whole foods might prefer incorporating other protein sources to get a wider range of vitamins and minerals.
The Pros of Just Egg Protein
- Accessible Plant-Based Protein: It offers a high-protein option for vegans and those with egg allergies.
- Cholesterol-Free: A huge benefit for individuals monitoring their cholesterol levels.
- Comparable Protein Quantity: Delivers a protein count per serving that is very similar to a large chicken egg.
- Sustainable Option: Compared to animal agriculture, plant-based alternatives like Just Egg generally have a lower environmental impact.
The Cons and Nutritional Gaps
- Missing Micronutrients: Lacks naturally occurring vitamins and minerals found in traditional eggs, such as Vitamin D, B12, and choline.
- Higher Sodium Content: It typically has higher sodium levels than a plain chicken egg.
- Processed Food: As an ultra-processed product, it may not align with the dietary preferences of those who prioritize whole foods.
- Not a Complete Protein: Mung bean protein isolate may not contain all essential amino acids in the right ratios, unlike a complete protein from eggs.
Conclusion: Does Just Egg Deliver on Protein?
Yes, Just Egg does have protein and delivers a comparable amount per serving to a large chicken egg. The protein comes from mung bean isolate, making it a valuable plant-based option for vegans, those with egg allergies, or anyone looking to reduce their cholesterol. However, the nutritional comparison is more nuanced. While Just Egg is a solid protein source, it lacks some of the essential vitamins and minerals found in traditional eggs and has a higher sodium content. Ultimately, Just Egg is a convenient and functional product that offers a good source of plant-based protein, but it is best viewed as part of a varied and balanced diet that addresses any potential nutritional gaps with other foods or supplements.
