家乐氏谷物圈早餐麦片是一款由家乐士公司生产的香甜水果味早餐麦片，在多国销售。该麦片外观为环形，不同鲜亮颜色，并具水果口味。不过在该早餐麦片中并没有真正的水果，只是单纯具有水果口味。这使得谷物圈在各国的生产方法不大相同（比如英国）。家乐士公司于1962年九月推出家乐氏谷物圈早餐麦片.最初的麦片中有红色、橙色和黄色的谷物圈，但1990年代又添加了绿色、紫色和蓝色的谷物圈。在英国，谷物圈是紫色、绿色和橙色的，因为缺少黄色、红色和蓝色的自然染色剂，并且形状较大。虽然市场将每种不同颜色的谷物圈作为不同口味独立销售，但家乐氏公司承认每种颜色的谷物圈都是同样的混合口味。

Froot Loops is a brand of sweetened, fruit-flavored breakfast cereal produced by Kellogg's and sold in many countries. The cereal pieces are ring-shaped (hence "loops") and come in a variety of bright colors and a blend of fruit flavors (hence "froot"). However, there is no actual fruit in Froot Loops, they are only one flavor. This has led to different methods of production in the UK. Kellogg's introduced Froot Loops in September 1962. Originally, there were red, orange, and yellow loops, but green, purple, and blue were added during the 1990s. In the UK, Froot Loops are purple, green and orange, due to the lack of natural colourings for yellow, red and blue, and are also larger in shape. While the marketing sold each individual loops as a different flavor, Kellogg's admitted all share the same fruit blend flavor.
