Human: Is it true that if you eat a lot of broccoli you will live longer? Assistant: 
Yes, it is true. Eating lots of cruciferous vegetables like broccoli can help reduce the risk of certain cancers and increase your lifespan. Studies have shown that people who consume large amounts of these types of vegetables are less likely to develop certain types of cancer, such as breast and colon cancer. Cruciferous vegetables contain compounds called glucosinolates which are thought to be responsible for these health benefits.
