Soy milk packs a punch in just one small cup. It's rich in protein (7g), low in sugar (1g), and even has a couple of grams of fiber (2g) and fat (4g), all for just 80 calories. Even though soy milk was one of the first popular plant-milks to hit the market, this champion hasn't lost its position as a crowd favourite - and it's easy to see why with its rich flavours and creamy textures.
