Creamy, delicious yogurt is also packed with nutrition. Depending on the brand, yogurt is a good source of protein, vitamin D, and calcium. These nutrients help build strong muscles and bones and provide energy. Read the label, though. A lot of the yogurt products made for kids are loaded with sugar and food coloring.


Fun Facts

  • Yogurt is milk that’s been fermented, or heated and mixed with bacteria. This bacteria — Lactobacillus bulgaricus and Streptococcus thermophiles – is good for your body and your digestion system and can help you stay healthy.
  • Greek yogurt is just regular yogurt that’s been strained. It contains more protein than regular yogurt and has a thicker texture.
  • Icelandic yogurt is even thicker than Greek yogurt and has even more protein. Kefir isn’t really yogurt at all. It contains different types of bacteria and yeast.
  • Yogurt contains lots of ingredients besides milk. It might be flavored with fruit puree, chocolate, sugar, vanilla, or honey. Starch, pectin, or gelatin is sometimes added to thicken it.
  • Look for yogurt that says “Live and Active Cultures.” This means the bacteria hasn’t been killed by a second heating. It might also mean the manufacturer has added bacteria.



  1. Bacteria: tiny organisms, some of which can make us sick
  2. Strain: to remove the liquid
  3. Puree: to finely mash a food
