Living on a college budget is hard. I know the inner battle between eating healthy and the alluring McDonald's Dollar Menu. It can often seem like it is impossible to eat healthy in college and not go broke, but worry no more: Here is a list of 10 healthy "super foods" that you can buy for less than $1 per serving.

1. Lentils

Cost per serving (1 cup): 15 cents

While similar to beans in its high protein and fiber content, lentils win this competition because of their easy preparation: only 15 to 30 minutes of cook time, no pre-soaking required.

2. Oats

Cost per serving (1 cup): 10 cents

The high fiber content found in oats can help decrease the amount of "bad" cholesterol in your body, and can also help you feel fuller longer. The key here is to make sure you stick to steel-cut or quick-cooking oats, and avoid the sugary pre-made oatmeal packets.

3. Kale

Cost per serving (1 cup cooked): 60 cents

I know that some people get scared of this notoriously healthy superfood, but in my opinion kale is a miracle food: one serving of kale has 10 times the recommended daily value of vitamin K and three times the daily value of vitamin A.

4. Almonds

Cost per serving (1 ounce): 63 cents

5. Oranges

Cost per serving (1 orange): 34 cents

One orange satisfies your entire daily requirement of vitamin C while also providing you with a great source of fiber and beta-carotene to help your vision. Plus, they taste amazing.

6. Peanut Butter

Cost per serving (2 tbsp): 21 cents

Ahhh, the God of all foods. Peanut butter not only tastes incredible, but also improves cholesterol and lowers risk of heart disease, along with providing healthy fats and vitamin E. Disclaimer: when buying peanut butter, get the natural kind to avoid an excess of added sugar and salt found in many name-brand peanut butter brands.

7. Apples

Cost per serving (1 apple): 28 cents

I guess the old expression "an apple a day keeps the doctor away" is true after all. While apples are not bursting with one specific vitamin, scientific studies show that regular consumption of apples has amazing benefits for your heart and your overall body health.

8. Eggs

Cost per serving (1 egg): 17 cents

These little things are like perfect little nuggets of nutrition, since they are bursting with protein, vitamin D, lutein, and xeanthanin (which lowers risks of a common disease that results in vision loss).

9. Carrots

Cost per serving (1 cup): 32 cents

Bugs Bunny was ahead of the game with this one. Just one cup of carrots delivers 4 times the daily value of vitamin A, which not only helps vision but also builds bone and helps support your immune system.

10. Mango

Cost per serving (1 cup): 71 cents

Just one cup of this wonderful fruit gives you 80 percent of your daily value of vitamin C, 25 percent of vitamin A, along with potassium and fiber. Plus, it tastes amazing frozen as a late night snack.
