Buckwheat is a type of plant that grows seeds which we can eat. It's kind of like a cousin to wheat, but it doesn't have gluten which some people can't eat.
When we eat buckwheat, we can make it into different things like flour, noodles, and even pancakes! It has a slightly nutty taste and is good for you because it has lots of vitamins and minerals.
Buckwheat is also very good for the environment because it doesn't need a lot of water to grow like other crops do. It's a cool plant that helps us make yummy food and is good for the planet too!
