The age-old debate of egg versus soya for protein intake has sparked a new discussion in the Indian context, where both options are increasingly popular. While eggs have long been a staple, soya is now a regular feature in many Indian diets, from tofu to soy milk. So, which one is the better choice for protein? The answer isn't as simple as it seems.
Eggs are a compact source of protein, with two eggs providing around 12 grams. However, soya's protein content varies widely, from tofu's 10-20 grams per 100 grams to dry soya chunks' higher concentration. This makes it challenging to compare the two directly.
But the real question is protein quality. Eggs have an edge here, as they provide essential amino acids in a highly usable pattern. A 2024 study in the Journal of Nutritional Science found that cooked eggs have an 'excellent' protein quality score for people over six months old, using the Digestible Indispensable Amino Acid Score (DIAAS) measure. This means eggs are more efficiently utilized by the body.
Soy, on the other hand, is still a strong plant-based protein source, with an average DIAAS of about 84.5. However, the score varies depending on the soy product and processing. Indian diets, which often include a variety of plant proteins, can benefit from this diversity. A 2026 review suggested that proteins from different foods can complement each other, so a diet with eggs, soy, dal, beans, and grains can still provide excellent nutrition.
For muscle-building, total protein intake throughout the day is crucial. Eggs are convenient for this, as a couple of eggs provide a significant amount of high-quality protein. Soy can also be effective, especially with protein-rich forms like tofu or soya chunks. Portion size is key, especially for older adults or those increasing protein intake.
In conclusion, eggs offer higher-quality protein, but soya can still be a valuable addition to an Indian diet. The choice depends on the specific needs and preferences of the individual. The key is to ensure a balanced diet with a variety of protein sources, rather than obsessing over one 'best' option.
