Eating Healthy on a Tight Budget -- College Edition

It seems difficult enough to eat on a budget, but is healthy eating even possible? 

My best friend has recently started a healthy lifestyle, no junk, no high sugars, etc. etc. As we will be living together as of next year (roommates!) I wanted to check out if it was even possible to accomplish/continue this healthy eating in college, especially as freshman. Below I will share some tips I found..

• focus on the veggies, they offer more nutrients at a low cost; remember that in-season veggies are cheaper
• stock up on staple foods such as rice, oats, pasta, beans, and veggies; it may cost more up front, but it will be worth it in the long-run 
• you really don't need that much meat, eat "cheap" protein such as eggs, fish, beans/lentils
• you really shouldn't care about the brand or company, the name may only be costing you more; opt for the cheaper of the two
• shop the sales, or look for any markdowns
• don't drink away your calories or budget, get a Brita Water Filter and drink clean tap water instead
• Planning out your meals beforehand can relieve stress and will ultimately help you save money. Create a list with the ingredients you need for the following week, this will create a goal and you will most likely stick to what you really need and not just grab items at random. 
• remember that leftovers can be used; ex: stock from boiling chicken is useful for creating soups, sauces, etc.
