General Mills has added to its Yoplait yoghurt line-up in the US with the launch of two variants as part of a tie-up with Weight Watchers.

Yoplait Light and Yoplait Greek 100, endorsed by Weight Watchers, are available from this month for a suggested retail price of US$0.79 and $1.29 respectively.

Yoplait Greek 100 is the only Greek yogurt endorsed by Weight Watchers, General Mills says, and is available in six variants including Strawberry, Black Cherry and Key Lime.

Newly-reformulated Yoplait Light has 90 calories per cup and is available in a number of variants from BlackBerry to Boston Cream Pie.
