Soy products are an important source of protein for millions of Indians—especially vegetarians. From soy chunks to soy milk, tofu, tempeh, and soy protein isolate, soy appears in many daily diets.
But with so many mixed opinions online, one question keeps coming up:

They are:
- High in protein (≈50–52%)

This makes them one of the most widely used vegetarian protein sources in India.
