Travel deductions

I am an independent consultant with assignments that can last 6 to 8 months on college campuses around the country. The college provides housing. 

 

1. If the housing is missing equipment, e.g. pots & pans, sheets, etc. which are not paid for by the college, and I have to buy them, is that an acceptable tax deduction on my business travel expenses?

 

2. If I buy groceries so I can prepare my own breakfast and dinner, is that a travel expense I can deduct from my taxes since I am away from home? 

 

3. While living on campus, if I go out for breakfast, lunch or dinner is that expense tax-deductible? 

 

4. If I go home on the weekends are the transportation expenses tax deductible? Currently, the college only pays for my initial travel expenses when I arrive at the college to start the assignment and when I finish the assignment and travel home.

 

Thank you.
