I've heard that a healthy diet can help prevent cancer. What are some good ways to get started?
assistant
1.  Start by eating plenty of fruits and vegetables, whole grains, lean proteins, and healthy fats like olive oil.
2.  Cut back on processed and red meats, which have been linked to an increased risk of certain cancers.
3.  Drink plenty of water throughout the day, as dehydration has also been linked to an increased risk of certain cancers.
4.  Try to limit your intake of foods high in sodium, since too much salt can increase your blood pressure and lead to other health issues.
