"take lunch", "have lunch" or "eat lunch"

Question: Do I say "I take lunch", "I have lunch" or "I eat lunch"?
Answer: "I have lunch" and "I eat lunch" are correct. "I take lunch" is wrong.

When you are talking about meals, you should use "has/have/had" or "eat/ate/eaten".

Examples:

• I am going to eat dinner.
• Have you had breakfast?
• I am having a meal.
• I have a lunch date.
• What to eat for lunch today?
• Stop talking while you are eating a meal!
