Soya Chunks vs. Chicken: The Protein Showdown
On the surface, the nutritional information for dry soya chunks suggests they are the undisputed protein king. Often marketed for their remarkably high protein content, a 100-gram serving of uncooked soya chunks can boast 52 grams of protein. This figure is often cited to claim superiority over chicken, but it is misleading without context. A fair comparison requires assessing the protein content of both foods in their prepared, edible state.
Once rehydrated and cooked, the water absorbed by soya chunks dilutes their protein density. Depending on the preparation method (boiled, soaked, or fried), the protein concentration per 100 grams can drop significantly, to around 15 to 28 grams. In contrast, a 100-gram serving of cooked, skinless chicken breast contains approximately 31 grams of protein. This puts cooked chicken breast on a comparable, and often slightly higher, protein-by-weight level than its plant-based competitor.
Complete Protein Profile: Amino Acids and Bioavailability
Both chicken and soya chunks are categorized as complete proteins, meaning they provide all nine essential amino acids required by the human body. This is a key advantage for vegetarians and vegans, as many plant-based sources are incomplete. However, there are differences in the amino acid profiles and how the body utilizes them.
Animal proteins like chicken typically have higher bioavailability, which means the body can absorb and use their amino acids more efficiently. While soy protein is also highly digestible, some sources note it has relatively lower levels of the sulfur-containing amino acid methionine compared to animal proteins. For most people eating a varied diet, this difference is negligible, but it is a point of consideration for those relying heavily on a single protein source.
Beyond Protein: A Look at the Nutritional Scorecard
Protein content is just one piece of the puzzle. Both chicken and soya chunks offer distinct nutritional benefits that cater to different dietary needs. Here is a comparative table detailing other key nutrients per 100-gram cooked serving:
| Nutrient | Cooked Chicken Breast (100g) | Cooked Soya Chunks (100g) |
|---|---|---|
| Protein | ~31g | ~15-28g |
| Calories | ~165 kcal | ~108-200 kcal |
| Fat | ~3.6g | ~0.5-12.5g (depends on prep) |
| Carbohydrates | 0g | ~9.5-16.5g (depends on prep) |
| Dietary Fiber | 0g | ~5-6g |
| Iron | ~0.9 mg | ~2.5-3.0 mg |
| Calcium | ~21 mg | ~75-90 mg |
Chicken breast is notably low in fat and has zero carbohydrates, making it an ideal choice for low-carb or keto diets. It is also rich in B vitamins, which are crucial for energy metabolism. Soya chunks, on the other hand, are a powerhouse of fiber, which supports digestive health and promotes feelings of fullness. They are also significantly higher in minerals like iron and calcium, benefiting bone health and iron levels. The final fat and calorie count for soya chunks varies dramatically based on preparation; boiling keeps it very low, while frying can increase it substantially.
Choosing Your Protein Powerhouse
The choice between chicken and soya chunks ultimately depends on individual dietary goals, preferences, and ethical considerations. For those seeking the highest protein density per cooked gram with minimal fat and zero carbs, chicken breast holds a slight advantage, along with superior protein bioavailability. This makes it a long-standing favorite for bodybuilders and those focused on lean muscle gain.
Conversely, soya chunks are a versatile and budget-friendly plant-based alternative that offers a unique combination of high protein and high fiber. They are an excellent choice for vegetarians, vegans, and anyone looking to increase their fiber and mineral intake while reducing their reliance on animal products. Soya chunks can be easily incorporated into many recipes to mimic the texture of meat, and their high fiber content is beneficial for weight management by increasing satiety. Some individuals with thyroid conditions are advised to consume soy in moderation, so consulting a doctor is recommended.
Both options are valid and nutritious additions to a healthy diet, each offering a distinct nutritional profile. For optimal health, a diet that incorporates a variety of protein sources, both animal and plant-based, is often the best approach to ensure a complete range of amino acids and micronutrients.

Conclusion
While dry soya chunks boast a higher protein percentage by weight, cooked chicken breast and cooked soya chunks offer comparable protein levels per 100 grams. Chicken provides a high-bioavailability, lean, carb-free protein source, while soya chunks deliver a significant dose of protein combined with fiber and important minerals. The superior choice depends on dietary preference, budget, and desired nutrient intake, affirming both as viable, healthy options for protein intake.
