Yesterday, we told you that sending in your Yoplait yogurt lids was an easy way to contribute to the fight against breast cancer — at the very least, those pink lids make you think about the disease every day when you eat your breakfast. However, we just want to make it clear that we don’t want you to start downing yogurt like it’s you’re job. Some organizations are against Yoplait’s Save Lids to Save Lives campaign, saying that the company uses milk from cows treated with an artificial growth hormone, which increases their milk production. Breast cancer is a health concern associated with the hormone’s use, but right now there is no clearcut evidence. We think you can decide for yourselves if you want to eat Yoplait, but if you are going to do so, you might as well send in your lids.
