Nutritional Tips to Boost Your Immune System in a Dorm Environment

Germs and illnesses abound on campus. Here's how to choose the best immune-boosting foods at the dining hall to keep you healthy at college.

It’s almost inevitable. When thousands of students share living spaces, dining halls, bathrooms, and classrooms, they’re bound to spread germs and illnesses. College kids living in dorms are especially vulnerable to spreading infections, as they spend so much of their time together in close quarters. What’s more, college students are apt to have unhealthy sleeping and eating habits, making them more susceptible to sicknesses.

While there’s no guaranteed way to avoid catching some sicknesses, like the cold or the flu, there seems to be something to the old saying, “an apple a day keeps the doctor away.” Eating a healthy, balanced diet at school is an important factor in keeping your immune system strong. This can help your body ward off some viruses. Plus, if you do come down with an illness, having a healthy immune system may help you recover more quickly. Here’s how to choose the best immune-boosting foods at the dining hall to help keep your immune system in fighting shape.

Nutrition for immune health

What you eat plays a vital role in your health. However, there’s no one food that’s sure to protect you from a cold, flu, or other viral infections of the respiratory tract. Rather, you need to eat a nutritious, balanced diet that’s rich in a variety of vitamins and minerals to properly fuel your body’s immune defenses. Choose foods with the following nutrients to support your immune health.

Zinc

Our bodies need zinc to keep our immune systems in top shape. Studies show that people with low levels of zinc may have a higher risk of pneumonia and other infections. This may be because zinc helps form and activate white blood cells, which we need to help fight off illnesses. Zinc may also help wounds heal in some people.

Be sure to include lean meats (such as chicken), seafood, milk, whole grains, seeds, and nuts in your diet to get enough zinc.

Vitamin A

Vitamin A aids in immune health by keeping your skin and the tissues in your digestive and respiratory systems healthy. Foods rich in vitamin A include carrots, sweet potatoes, eggs, and fortified foods.

Vitamin E

Vitamin E has been associated with enhanced immune function. In fact, one symptom of a vitamin E deficiency is a weakened immune response. Sunflower seeds, almonds, hazelnuts, peanut butter, and fortified cereals all contain vitamin E.

Vitamin B6

Vitamin B6 is needed to make cells of the immune system so it can fight off infections. Foods containing vitamin B6 include chickpeas, tuna, salmon, chicken, and potatoes.

Vitamin C

Many people assume that vitamin C would top this list, as it’s a popular belief that it can prevent or even cure a cold. But the research doesn’t exactly back up this claim. Vitamin C only seems to lower the risk of getting a cold in extremely active people, such as marathoners and armed forces members who train intensely in artic weather. Although vitamin C doesn’t seem to affect the average person’s risk of catching a cold, some studies show that consuming 200 milligrams per day may slightly shorten the duration of a cold by about one day.

Foods high in vitamin C include citrus fruits (like oranges and grapefruits), red bell peppers, and strawberries. Other foods that don’t naturally contain vitamin C, like certain cereals, may be fortified with the vitamin.

Helpful herbs and spices

Certain herbs and spices are packed with nutrients, and using them in your food may help build up immunity, stop the growth of germs, and reduce inflammation in the body. Stock your pantry with these items:

Garlic

This herb has been used to flavor dishes in many cultures, and it’s also touted as a cold remedy. One small study shows that garlic may lessen the severity of cold and flu symptoms, but more research is needed to know if this is true.

Cinnamon

This commonly used spice may aid in immune health by affecting the growth of bacteria and viruses.

Turmeric

This bright yellow spice is used to flavor curry dishes, and it may also decrease inflammation and strengthen your immune system.

Benefits of whole foods

Note that it’s best to get nutrients from whole foods instead of taking them in supplement form. When you eat whole foods, you get a variety of vitamins, minerals, and other benefits like fiber, phytochemicals, and antioxidants, which may help support immune function and protect against various chronic diseases.

CollegeXpress has helped me with all aspects of applying for college. The website is extremely easy to navigate and gives access to so many resources. I was able to research all of the colleges I was interested in, find out any information I wished to know about, and keep them organized in a list. I've also been able to research scholarships and save them as resources for later. I've used many websites in my college and scholarship search, and CollegeXpress has by far been my favorite one to use.

I've used CollegeXpress quite a bit as a senior, particularly for colleges and scholarships, so it's been a very big asset in that respect! I would recommend it to anyone looking to pursue a college education, especially seniors! This scholarship will help me achieve my goals in ways I couldn't have before, and I know that there are opportunities like that for everyone on the website and in the magazines!

As I transition to furthering my education, I can say with certainty that it simply wouldn’t be possible without the help of generous organizations such as CollegeXpress. Those who initially founded CX had no idea their platform would give a plethora of information to a first-generation homeless kid native to the ghettos of over half a dozen states. Everyone at CX and Carnegie Dartlet gave me a chance at a future when the statistics said I had none. And for that, I thank them.

CollegeXpress helped open me up to many colleges that fit my interests. I’m only a sophomore in high school, so I like having a lot to look at, and CX does a great job of picking colleges that meet my wants. It's a great website that I'll continue to use until it comes time for me to apply for colleges. I also like that it notifies me through email with options to look at. Thanks CX!
