This is a fun lesson that helps middle school/high school students understand why processed foods can be so unhealthy. This lesson is fun because students get to guess what the foods are. My students love that part! They also do a very good job picking out the different fats and sugars and only just occasionally need my help. This is a great lesson for a health class but if you teach family and consumer sciences or have access to kitchens, students can make hands on versions of popular processed foods.
