As the weather turns colder and we spend more time indoors, viruses will become more active among the population. Healthy eating can help you boost your immunity. Here are five of the top choices for fighting colds and flu with food.

Citrus Fruits

Oranges, clementines, lemons, and grapefruits are all excellent sources of vitamin C, an antioxidant that helps protect immune cells from oxidative stress during the early stages of an immune response. Research has shown that a deficiency of vitamin C can result in impaired immunity and a greater susceptibility to infection.

Fatty Fish

Fatty fish, such as sockeye salmon and rainbow trout, are often great sources of Vitamin D, a nutrient that plays a role in innate and adaptive immune responses. One study found that vitamin D supplementation resulted in a 42% decrease in the incidence of influenza infection, while another study revealed individuals with lower serum vitamin D levels were more likely to self-report recent upper respiratory tract infections when compared to individuals with sufficient vitamin D levels.

Nuts, Seeds, and Plant-based Oils

Nuts, seeds, and plant-based oils are high in vitamin E, an antioxidant that has been shown to enhance immune response and confer protection against several infectious diseases. These foods are also high in omega-3 fatty acids, which may help strengthen your immune cells, although more research is still needed to fully support these claims.

Sweet Potatoes

Sweet potatoes and other red or orange fruits and vegetables are typically high in vitamin A, which plays a crucial role in the maintenance of the human immune system. Vitamin A supplementation has been shown to have a therapeutic effect on diseases transmitted through the respiratory tract, such as pneumonia. For reference, one sweet potato contains 156% of your daily vitamin A requirements.

Oysters

Three ounces of raw oysters provides 291% of your daily zinc needs. Zinc helps the immune system function properly and also has wound-healing properties. Studies have shown that a zinc deficiency is associated with severe immune dysfunction.

Eating the preceding types of foods can help you strengthen your immune system against the annual winter onslaught of colds and flu. If you’d like more help planning a healthy diet, schedule a NIFS nutrition coaching session.

It is estimated that there are almost 48 million cases of foodborne illness/food poisoning in the United States each year (source: https://www.foodsafety.gov/food-poisoning). Of these cases, around 128,000 individuals are hospitalized and about 3,000 deaths occur. Rates of foodborne illness are higher during the summer months, as they are often warmer and more humid—the ideal environment for bacterial growth. In addition, many people participate in outdoor food-related activities, such as picnics, barbeques, and campsites, where the typical safety controls of a kitchen, such as refrigeration, cooling, and running water, are not always available

Keep reading to learn about the common causes of food poisoning, their symptoms, and steps you can take to protect your food this summer.

Common Food Poisoning Culprits and Their Symptoms

The onset time of the signs and symptoms of food poisoning depend on the type of virus, bacteria, or other pathogen you were exposed to and the symptoms can range from mild to severe. Some of the most common food borne illness causing pathogens and their symptoms include the following.

Salmonella

Listeria

Symptom onset: 1 to 4 weeks after exposure.

Signs and symptoms: headache, stiff neck, fever, muscle aches.

Food sources: Soft cheeses, raw sprouts, fresh melon, hot dogs, and other deli meats.

Individuals at Increased Risk for Foodborne Illness

People who are most at risk include the following:

• Pregnant women and infants.
• Children younger than 5 years old.
• Elderly (> 65 years of age).
• Immunocompromised (cancer, HIV/AIDS, autoimmune diseases, etc.)

6 Steps for Practicing Food Safety This Summer

Follow these tips to avoid food poisoning at your summer gatherings.

Wash Your Hands

Always wash your hands with warm, soapy water for at least 20 seconds before, during, and after food preparation and handling. Be sure to dry your hands completely after washing using a clean towel. If you don’t have running water or access to safe water, be sure to bring wet disposable wipes, paper towels, and surface disinfectant for cleaning hands, cooking surfaces, and utensils.

Keep Cutting Boards and Utensils Clean

Use separate cutting boards, serving dishes and other utensils (tongs, spatulas, etc) for cooked and raw foods. Be sure to thoroughly wash all items that come into contact with raw food with warm soapy water prior to reuse.

Get a New Plate After Handling Raw Meats

Never serve cooked foods on the same plate or platter that once held raw meat, poultry, or fish to avoid cross-contamination.

Thaw in the Refrigerator

Thaw food in the refrigerator rather than at room temperature or on the counter.

Cook to Safe Internal Temperatures

Use a food thermometer to ensure the food reaches safe internal temperatures:

• Beef, pork, lamb, veal (steaks, roasts, chops, etc.): 145F
• Ground meats (hamburgers, etc.): 160F
• Whole and ground poultry (chicken, turkey): 165F

Don't Leave Food Out

Refrigerate leftovers within 2 hours after cooking. If outdoor temperatures exceed 90F, refrigerate perishable foods within 1 hour. Keep your refrigerator below 40F.

As many of us are confronted with the decision of whether to send our children back to school or continue with online learning, we are faced with many questions that we had never had to ask ourselves before. Breakfast, lunch, and often snacks are mainly consumed during these hours at school, so as we continue to see Indiana trying to return to normal and reopen, we might need to tailor our eating habits to ensure we are not risking unnecessary exposure to COVID-19 when refueling our bodies throughout the day. These ideas also work for adults who are returning to the workplace or have already returned to the workplace.

Keep in mind, you want each meal to be comprised of plenty of fruits and veggies (half of your plate), while one quarter of your plate is filled with a protein, and the remaining quarter is filled with a minimally processed grain like brown rice or whole-wheat pasta. Make sure to use leftovers to make the next day’s meal prep easy—think large-batch cooking. Snacks should have a protein (such as nuts, peanut butter, etc.) along with a high-fiber carbohydrate like a piece of fruit (think banana or apple) to keep you feeling satisfied throughout the day.

Tips for Safe Eating at Schools and Work

Here are some actions to consider when eating meals at work or school amid a pandemic:

• Cut back on items that require heating up in the microwave to avoid touching a community microwave.
• Use a thermos if you would like to take hot items (such as coffee or soup).
• Pack a bottle of water (drinking fountains are likely to be closed).
• Practice “hands-free” snacking. An example for kids: toothpicks already placed into small sandwich squares that they can pick up like an hors d’oeuvre makes for a fun and safe way to eat finger foods!
• Use packaging to avoid touching food prior to ingesting food items.
• Practice good hand hygiene. Scrub with soap and water for a minimum of 20 seconds and don’t touch other items prior to eating.
• Bring your own utensils, napkins, and condiments.
• Vary the times you visit the cafeteria if possible to avoid high-traffic times.
• Keep your mask on as long as possible and try to sit at least 6 feet apart.

Meal and Snack Ideas

Take a look at some of these meal and snack ideas and give them a try. Keep in mind that these are suggestions, and I hope they provide inspiration. Although they don’t cut out your risk 100 percent, every little bit helps during this crazy time.

Breakfast Ideas

• Smoothie: 1-2 cups of frozen fruit, a handful of leafy greens, a spoonful of peanut butter, and milk of your choice blended to your preferred consistency. Pack in a thermos and bring your own straw.
• A banana and a squeezable almond butter packet (such as Justin’s).
• Overnight oats: soak rolled oats in milk in the fridge overnight with a dollop of peanut butter. Add fresh or frozen fruit on top. Eat cold or throw in the microwave before leaving the house (it retains heat well!).

Lunch Ideas

• Sandwiches on whole-wheat bread: wrap in parchment paper to avoid touching the sandwich when eating it. Skip the deli meats and try to load up on colorful and crunchy veggies with hummus in this option.
• Pasta salad: bring your own utensils. Make a big batch of whole-wheat pasta and sautéed veggies and toss with balsamic vinegar and olive oil in the morning. Toss in a can of pinto beans or a handful of pine nuts for an easy protein.
• Spinach salad: top with carrots, cherry tomatoes, walnuts, and chickpeas. Toss dressing on at lunch.

Snacks and Sides Ideas

• Squeezable applesauce pouches
• Larabars
• Mamma Chia Squeeze pouch
• Yogurt with a banana—I love the Silk soy yogurt for a dairy-free option
• Individual bags of prepopped popcorn (try pouring it into your mouth straight from the bag—it might not look graceful at times, but it keeps your fingers out of your mouth!)
• Precut fruit salad (apples, strawberries, blueberries, etc.)
• Precut/bite-sized carrots, cucumber, and celery that you can easily stab with a fork or toothpick and dip into a little hummus

While this is not an easy time for anyone, trying to keep up your routine in eating habits is important so that your body is properly fueled and healthy. Best of luck this year, and stay healthy!

During these unprecedented times of self- and mandated quarantines and stay-at-home orders, it can be easy to slip into a negative mindset accompanied by fear of the unknown and worry about how you are going to get through this. Self-quarantine does not have to be void of self-improvement. Social media is drenched with ideas and strategies to keep up your physical fitness at home with a million bodyweight workouts and DIY fitness equipment ideas. I’m partial to the elite content that the NIFS pros are providing daily, obviously, but there is no shortage of methods out there to keep moving at home. But what about emotional and mental fitness, and how to continue the work on YOU that makes us strong individuals inside and out?

A motto that I live by daily is to focus on how you choose to react to an unavoidable situation and not let the situation itself dictate your response. Many things are out of our control, but we can control the way we react. I’m sure you’ve seen that poster sometime in your life, and I think it is the only way you can actually control a situation you find yourself in. This fight against COVID-19 is no different; the situation itself is out of our control, but the way we choose to react and manage the situation is.

Strategies for Mindset Pivot

So how can we PIVOT our mindset and continue our self-growth through this crazy situation? I have a few strategies that you can put in place right away, starting with the mindset PIVOT.

Be Grateful

List and define the things that you are grateful for right now. Obviously, this is not an ideal situation we are all going through, but what are the things that you have or that are going on in your life that you are so thankful for? Here are a few of mine:

• I’m healthy.
• My loved ones are healthy.
• I’m still able to remain employed and help others.
• I have a safe and comfortable home.
• I have ample food.

I’ll bet as soon as you put pen to paper and write out those things you are grateful for, you will begin to pivot to a more positive mindset.

Laugh

Find ways to laugh daily. Maybe it’s listening to your favorite comedian or catching a comedy on Netflix. Laughter can change a mindset pretty quickly and will focus attention away from the troubling news we face these days.

Connect

Spend time with your family that is with you and reach out to those who are not. You have some time now to really connect with the people you care about the most. Play a game with the kids, call someone you haven’t talked to in a while, send an email, or Skype. There are so many ways you can connect with others. Stay connected; you have the time now.

Move

There are a number of ways you can remain active at home. As I stated before, there is no shortage of drills and workouts you can do with little and no equipment online and on social media. Follow your NIFS Pros on IG and Facebook and be sure to check out our blogs for a ton of fitness strategies you can do at home:

• Quick Workouts
• Mini-Band Exercises
• Slider Exercises (use paper plates on carpet or a towel on wooden surfaces)
• Super Band Exercises

Be sure to PLAY as well, an aspect of fitness that often gets overlooked. Play and smile!

Strategies for Self-Growth

Even though you may be a homebody these days, it doesn’t mean you have to stop the growth of who you are as an individual, professional, parent, sibling, and other identities that you carry with you. The list of things you can do to grow and not slow down during this time is long. Here are just a few to wet your whistle:

• Read a book(or books) covering a topic you want to learn more about.
• Listen to a podcast.
• Watch a documentary, take a break from the world of fiction to gain knowledge of an interesting topic.
• Help the kids with their e-learning.
• Evaluate and adjust those New Year’s goals you wrote down a few months ago.
• Plan a future vacation and determine the steps needed to get you there.
• Journal daily thoughts, kind of like a “captain’s log” type of thing.
• Take a nap.
• Keep moving (see above).
• Hop on a webinar.
• Declutter the house and give it a deep clean.

We are going to get through this and return to our lives outside of the house. A challenge to you is to be a better YOU than you were at the beginning of this pandemic. Taking action during this time to maintain a positive mindset and to continue to grow mentally and emotionally will set you up for success when you reenter the world. Control your reaction, take action, and we will come out of this situation better than ever!

1. Stock up on nutritious foods from all food groups.
Think shelf-stable or frozen foods. Shelf-stable, nutrient-packed options include whole grain rice, chickpea- or lentil-made pastas, tuna, beans, nuts, legumes, protein pancake mixes, oats, nut butter, protein bars, low-sodium canned vegetables, and canned fruit in water. Frozen foods include pre-frozen bags of fruits, vegetables, and Greek-yogurt bars. Fresh options that can be frozen include sliced bananas, chicken, turkey, beef, seafood, bread, and tortillas. Eggs are also a great fresh option that keep well in the fridge for 3 weeks.

2. Fuel your body by eating regular, nutritious meals and snacks.
This will help to meet your caloric, vitamin, and mineral needs.

3. Stay hydrated
Drinking at least half your weight in ounces. If you have a fever, you will want to drink much more.

4. Have a menu plan
In case you do become quarantined or are socially distancing yourself, the plan should include enough daily meals and snacks to meet each family member’s caloric needs for 4-6 weeks. When planning those meals, try to incorporate all food groups into each day (vegetables, fruits, grains, dairy, and protein) and plan each portion size. Here is an example for 1 person:

• Breakfast: ½ cup oats with ½ cup berries (use frozen), 2 tbsp peanut
  butter, and 1 tbsp chia seed
• Snack: 1 granola bar with 1 hard-boiled egg
• Lunch: Stir fry (use low-sodium canned vegetables or frozen vegetables,
  brown rice, and canned or frozen meat of choice)
• Snack: 1 peanut butter and jelly sandwich (freeze bread, then unfreeze
  a loaf for each week) with 1 serving baked chips.
• Dinner: ¾ cup chickpea pasta served with ¼ cup tomato sauce, 1 cup
  steamed vegetables (use frozen vegetables or fresh vegetables with a
  longer fridge life), and ¼ cup cheese (freeze shredded cheese then
  unfreeze as needed)
• Dessert: 1 frozen yogurt bar

5. Seek community resources as needed. Many communities are coming together to help people obtain food. For Indy and surrounding communities, visit https://www.indy.gov/activity/covid-19-food-support , for food support initiatives.

During cold and flu season, we try to do all we can to prevent illness or speed up how fast we recover from illness. One such strategy many employ is the use of Vitamin C for a natural remedy. Several products are marketed as immune system boosters because they contain large amounts of Vitamin C. Do these products really work? We set out to investigate!

What Vitamin C Can Do for You

Vitamin C, also called ascorbic acid, is not made by our bodies. We must take in this vitamin in our diet. It is needed for not only immune function but also for these uses:

• Form collagen (skin, tendons, ligaments, and blood vessels),
• Repair and maintain bones and teeth
• Heal wounds and form scar tissue
• Aid in iron absorption

It can also help prevent cancer as an antioxidant by blocking damage that we are exposed to from air pollution, cigarettes, and UV rays from the sun.

Vitamin C deficiency is extremely rare today, but in the mid-1700s scurvy in sailors was very prevalent. Those at risk of low vitamin C intake are smokers, those with medical conditions that affect absorption (cancer cachexia), and individuals with little variety in their diets.

How Much Vitamin C Do You Need?

The recommended Dietary Allowance for men is 90 milligrams per day and 75 milligrams per day for women. Fruits and veggies are the best source of vitamin C—especially citrus fruits. It can be destroyed by heat, so cooking slightly reduces your intake. However, most of our best sources of vitamin C are consumed raw naturally, and we usually do not have to worry about this. To get a better idea of how to meet your daily requirement with food, here are the vitamin C contents of some common fruits and vegetables that are good sources:

• Red bell pepper (½ cup, raw): 95mg
• Orange, 1 medium: 70mg
• Green bell pepper, ½ cup raw: 60mg
• Broccoli, ½ cup cooked: 51mg
• Cantaloupe, ½ cup: 29mg

In short, you can skip the megadoses of Vitamin C at the pharmacy.

Can Vitamin C Treat or Prevent the Common Cold?

In the 1970s, research was released that suggested Vitamin C could successfully treat or prevent the common cold. Several studies since then have been inconsistent and have resulted in some confusion and controversy. To date, the most compelling evidence comes from a 2007 study that showed preventative treatment in the general population did not affect cold duration or symptom severity. However, in the trials involving marathon runners, skiers, and soldiers exposed to extreme physical exercise or cold environments daily as well as the elderly and smokers, there could be somewhat of a beneficial effect. It was concluded that taking Vitamin C after the onset of illness did not appear to be beneficial. Furthermore, at doses above 400mg, Vitamin C is excreted in the urine. A daily dose in the 1000–2000mg range can cause upset stomach and diarrhea.

If you want the benefits of Vitamin C, it is best to consume the recommended Dietary Allowance daily, before the start of symptoms. Ideally, you will get Vitamin C from your food instead of a supplement; you will also get several other important nutrients in addition to your Vitamin C. Remember to make half of your plate fruits and veggies at every meal or blend up a quick smoothie for an easy on-the-go snack, slice up peppers and dip in hummus, or ask for extra veggies on that sandwich, pizza, or salad.

Have you ever noticed that during the cold and flu season, some people just don’t get sick no matter what? Or maybe you have wondered why after being exposed to the same virus, one person gets sick while the other doesn’t.

The answer to that lies in your immune system and how strong it is. When you are exposed to bad bacteria or viruses, it’s up to your immune system to protect you from being infected. If your immune system is strong, your body will fight off the threat of sickness. If you have a weak or compromised immune system, you may end up sick. What you might be surprised to learn is this: The strength of your immune system is highly dependent on the condition of your digestive system.

The Good, the Bad, and the Ugly: Let’s Talk Microbes

Microbes live inside your digestive system. They are living organisms that affect your overall health. The protection that some of these organisms provide is beneficial to your immune system. The good bacteria recognize when illness-producing intruders enter your body; the organisms attack the intruders so that you don’t get sick. If you don’t have enough of the good bacteria in your gut, you will be more susceptible to viruses like colds and stomach viruses. You also may be at more risk for autoimmune diseases such as colitis, rheumatoid arthritis, and Crohn’s disease.

Although there is a large supply of these good microbes living in your gut, they can easily become diminished. If you have recently taken antibiotics, you have not only wiped out the bad bacteria, but also the good bacteria. Antibiotics are not selective in their destruction.

With that being said, antibiotics are not the only way that good bacteria becomes exhausted in your digestive system. For example, the chlorine in your drinking water can destroy them, as can the pesticide residue on the food that you eat.

Once the supply of helpful microbes in your intestines dwindles, bad microbes such as yeast, fungi, and disease-causing bacteria begin to take over. Immune systems become compromised when the bad takes over the good.

Cue the Probiotics

If you think that your good microbes might be minimal, it is not difficult to remedy the problem. The solution is to take probiotics. These are the good microbes that you can consume in your diet. Once they have entered into your body, they settle in your digestive system and get to work protecting you from sickness and destroying the bad bacteria that might reside there.

The option of consuming probiotics in a capsule form is there, but you can also replenish the good microbes by eating yogurt. Check the label to be sure that the yogurt you buy says that it contains active cultures, which is the good bacteria that you need to eat.

It is important to act now and get a jump on this year’s cold and flu season. Improve your gut function and fight off illnesses by getting ahead of the game.
