13.2: Taking Care of Your Physical Health

Questions to consider:

• What is healthy eating?
• Why is it important to stay hydrated?
• How important is exercise to a healthy body?
• Are you getting enough sleep to be healthy?
• What are toxins, and how can they affect your health?

You have one body. Treat it well so as to maximize its ability to serve you throughout your life. Often physical health gets moved to the bottom of the priority list when we are busy. Taking care of your physical health doesn’t mean six-pack abs or training for a marathon. It means honoring your physical needs so your body can function properly, feeding your cells the nutrients that will keep your body working well your entire life, and minimizing exposure to toxins to reduce your risk of disease.

DIET

A diet is anything that you consume on a regular basis. If you drink Diet Coke for breakfast every day, that’s part of your diet. When people talk about “going on a diet,” they usually mean changing their existing dietary habits in order to lose weight or change their body shape. All people are on a diet because everyone eats!

Having a healthy diet means making food choices that contribute to short- and long-term health. It means eating the right amounts of nutrient-rich foods. The right mix can help you be healthier now and in the future. Developing healthy eating habits doesn’t require you to sign up for a gimmicky health-food diet or lifestyle; you don’t have to become vegan, gluten-free, “paleo,” or go on regular juice fasts. The simplest way to create a healthy eating style is by learning to make wise food choices that you can enjoy, one small step at a time.

Healthy Eating in College

College offers many temptations for students trying to create or maintain healthy eating habits. You may be on your own for the first time, and you’re free to eat whatever you want, whenever you want. You may not be in the habit of shopping or cooking for yourself yet, and, when you find yourself short on time or money, it may seem easier to fuel yourself on sugary, caffeinated drinks and meals at the nearest fast-food place. Cafeterias, all-you-can-eat dining facilities, vending machines, and easy access to food twenty-four hours a day make it tempting to choose hyper-palatable, nutrient-deficient unhealthy foods and overeat.

Ideas for healthy eating

• If personally tolerated, eat foods from all the major whole food groups
• Whole, natural foods generally are the most nutrient-dense
• Plan ahead and schedule a time to shop for groceries, prepare, and cook
• Pack your lunch and snacks to better ensure healthy eating on the go
• Drink plenty of water

There are a wide array of healthy foods and ways of eating. Like exercise, find the healthy foods and dietary approach that you like, that makes you feel good, and that you can naturally and easily sustain your lifestyle.

As you find what works for you, it’s important to remember that it’s common for people to overeat (or not eat enough) when they feel anxious, lonely, sad, stressed, or bored, and college students are no exception. It’s incredibly important to develop healthy ways of coping and relaxing that don’t involve reaching for food, drink, or other substances. While self-care does involve the health trinity, there are other important elements, including stress management.

ACTIVITY : PLANNING A HEALTHY DAY

Planning a Healthy Day

It’s been said that if you fail to plan, you plan to fail. Take a few minutes and write out what a full day of healthy eating looks like for you.

• What would you eat? What would you not eat?
• How much would you eat?
• How often would eat?
• What would you drink? What would you not drink?
• How much would you drink?
• What, if anything, do you need to do to help you do this on a daily basis?

Use your findings as a way to begin to design a healthy eating meal plan for yourself.

Healthy Eating

While it’s not the only thing that contributes to great health, what you eat makes a huge difference. We have 37 trillion cells in our body. The only way they function optimally is with good nutrition. As a college student, you will be surrounded by temptations to eat poorly or even to overeat. It’s now up to you to make wise choices in the face of these temptations. Your dining hall is likely full of many healthy foods and just as many unhealthy foods. You may grab food on the run while racing to class or order a pizza at midnight while studying for a test. Lobby vending machines or a stash of snacks in your room should not turn into a substitute for real meals. The downside of fast food and easy access treats is that many are loaded with sugar, salt, or both.

The United States Department of Agriculture (USDA) updated their Healthy Plate Guidelines in 2011. MyPlate illustrates five different food groups considered the building blocks for a healthy diet—vegetables, fruits, protein, grains, and dairy.

Figure 13.2: Eating healthy is a journey shaped by many factors, including our state of life, situations, preferences, access to food, culture, traditions, and the personal decisions we make over time. The USDA recommends that vegetables and fruits make up the largest portions of your diet, and dairy the smallest portion. All your food and beverage choices count. MyPlate offers ideas and tips to help you create a healthier eating style that meets your individual needs and improves your health. (Credit: USDA / Public Domain)

It’s also important to know what is not a healthy plate. A healthy plate is low in refined carbohydrates (donuts, pastries, pasta, cookies), low in sugar, and low in saturated fat (although we need healthy fats like avocado and nuts). You can learn more at choosemyplate.gov [www.choosemyplate.gov].

While the USDA’s MyPlate was revised to reflect some key findings at that time, nutritionists at Harvard felt it didn’t offer the most complete picture when it comes to basic nutrition guidelines. They created The Healthy Eating Plate, which is based on what they consider to be the best available science. Similar to MyPlate, half the plate is vegetables and fruit. Aim for eight servings of veggies or fruits a day, more veggies than fruits. It’s important to note that the Harvard version was created without the political pressure from food industry lobbyists (for example, the dairy industry). Note that grains are further defined as whole grains, protein is now healthy protein, and water is emphasized over dairy/milk. What other differences do you see?

This table(opens in new window) provides more detail on how The Healthy Eating plate compares to USDA’s MyPlate.

Healthy eating also includes choosing organic fruits and vegetables when possible. By choosing organic, you help lower the amount of toxins your body encounters (since conventional fruits and vegetables are often sprayed with pesticides). Organic foods may not be readily available on your campus or in your local grocery store, so strive to choose the best options possible given availability and your budget. Many college and universities are adding organic food as a result of student demand. If healthy eating is something you are passionate about, consider organizing an effort to influence the dining options on your campus. When shopping on your own, the Dirty Dozen list provided by the Environmental Working Group (EWG) is a good guide of which produce is most important to eat organic, as these are the fruits and vegetables with the most pesticide residue. The EWG also compiles a Clean 15 list(opens in new window) of the vegetables and fruits with the least amount of pesticides.

Whole Foods vs. Processed Foods

Choose whole foods. Whole foods are any foods that have not been processed, packaged, or altered in any way. Whole foods are an essential part of a healthy diet because they contain the vitamins and minerals our bodies need.

Examples of whole foods include the following:

• Vegetables: Carrots, broccoli, kale, avocados, cauliflower, spinach, peppers
• Fruits: Apples, bananas, blueberries, strawberries, grapes, melons, peaches
• Grains: Brown rice, oatmeal, barley, buckwheat, quinoa, millet
• Beans: Black, pinto, kidney, black-eyed peas, chickpeas

Minimize non-whole foods. These are foods that have been processed, such as cookies, hot dogs, chips, pasta, deli meat, and ice cream. Even seemingly healthy foods like yogurt, granola, and protein bars are processed and should be checked for added sugar and other unhealthy ingredients.

The average American eats 62 percent of their daily calories from processed foods.³ In order for your body to be as healthy as possible, it’s extremely important to include lots of whole foods in your diet.

"When you eat junk food you think junk thoughts."

— Michael Bernard Beckwith

How to Read a Food Label

The U.S. government requires food manufacturers to put a label on every processed food product. This is so we, as consumers, know what we are putting into our bodies and can make good dietary choices. A quick review of the label will provide a lot of important information about what you are eating, yet most people don’t take the time to read the label. This is a big mistake.

Think of the front of the package as a marketing billboard. Don’t be fooled by the marketing. Every day millions of dollars are spent to persuade us to eat foods that are not healthy for us. Through visuals (like the strawberry on the bottle of dressing below) and words (like natural, healthy, or gluten free), the food industry wants us to make assumptions about the nature of a food product without looking at the facts. For example, many people eat protein bars thinking they are a healthy choice, but protein bars can have up to 30 grams of sugar! Understanding the nutrition information and ingredients will help you make healthier choices. When you take the time to read the labeled ingredients, you are no longer being marketed to—you are staring at the facts.

Figure 13.3: This label displays the key nutritional information about a common container of fruit salad. Though fruit is generally healthy, be aware of the amount of calories and sugars, and particularly the serving size to which those amounts are tied. Note that the US government has updated food label requirements and this version of the label will soon be the only one you’ll see. (Credit U.S. Food and Drug Administration / Public Domain)

Look at the label on the back of what appears to be a healthy item: fruit salad or fruit cocktail. One of the first things to look for is the amount of sugar. 12 grams equals just under 2.5 teaspoons. The serving size indicated is 2/3 cups, so if you have double that amount, it’s the equivalent of spooning out 5 teaspoons of sugar. The lower the sugar the better.

It’s also important to avoid high amounts of sodium, to minimize saturated fats, and to avoid all trans fats. Trans fats are unhealthy substances made through the process of solidifying liquid oils to increase the shelf life of foods. Also called partially hydrogenated oil, trans fats are often found in margarine, microwave popcorn, crackers, cookies, and frozen pizza. Saturated fat usually comes from animal products like butter and meat fat. Saturated fat tends to raise the level of cholesterol in the blood, and while some is OK, moderation is best.

Dietary fiber is a good thing; the higher the number the better. Fiber has virtually no calories, but it holds water in your stomach, makes you feel full, and helps with digestion. Vitamins are very important. Aim to get to 100 percent of your recommended daily value through the food you eat throughout the day.

Next, look at the ingredient list that can be found at the bottom of the nutrition label. A long list of ingredients likely contains fillers and preservatives you should avoid. If you can’t pronounce an ingredient, you can generally assume it is not a healthy option. And it’s not only what you eat, it’s what you don’t eat. As a rule, the fewer the ingredients, the better.

This video on how to read a food label(opens in new window) is a helpful overview on what else to look for.

You can also download the Fooducate app, which allows you to scan the bar code of any food item and quickly see a report card and suggestions for healthier alternatives.

ANALYSIS QUESTION

Take a few minutes to write down everything you ate in the last two days. Now review your list and estimate what percent of your food intake came from whole foods. How did your meals compare to The Healthy Plate? Where is there opportunity for healthier choices? How can these changes benefit you?

What You Drink

What is your go-to drink when you are thirsty? Soda? Juice? Coffee? How about water? Most of your blood and every cell in your body is composed of water. In fact, water makes up 60 to 80 percent of our entire body mass, so when we don’t consume enough water, all kinds of complications can occur. To function properly, all the cells and organs in our body need water. Proper hydration is key to overall health and well-being. By the time you feel thirsty, you are already dehydrated. Dehydration is when your body does not have as much water and fluids as it needs. Researchers at Virginia Polytechnic discovered that mild dehydration (as little as losing 1 to 2 percent of body water) can impair cognitive performance.⁴ Water increases energy and relieves fatigue, promotes weight loss, flushes toxins, improves skin complexion, improves digestion, and is a natural headache remedy (your brain is 76 percent water). Headaches, migraines, and back pains are commonly caused by dehydration. Your body will also let you know it needs water by messaging through muscle cramps, achy joints, constipation, dry skin, and of course a dry mouth.

Aside from feeling thirsty, the easiest way to tell if you are dehydrated is to check your urine. If it is a dark shade of yellow, your urine is over-concentrated with waste. This happens because water helps flush out waste and when you’re hydrated there’s a higher ratio of water to waste, turning your urine a lighter color.

One of the best habits you can develop is to drink a large glass of water first thing in the morning. Your body becomes a little dehydrated as you sleep. Drinking water first thing in the morning allows your body to rehydrate, which helps with digestion and helps move the bowels for regularity in the morning. It also helps to eliminate the toxins your liver processed while you slept.

Check out this video(opens in new window) for more benefits of drinking water.

Staying hydrated is important to keep your body healthy, energized, and running properly. As a general guideline, aim to drink eight glasses of water a day, although a more helpful guide is to drink half your body weight in ounces (for example, if you weigh 150 lb, try to drink 75 oz of water a day). One of the best ways to remind yourself to drink throughout the day is to buy a reusable bottle and bring it everywhere you go. There are two reasons to use a refillable water bottle instead of a plastic bottle:

1. Your own health. Most plastic water bottles have a chemical called bisphenol A (BPA), which is added to plastics to make them more durable and pliable. BPA is known to disrupt hormones and has been linked to sperm dysfunction.
2. The health of the planet. Do you know that every time you drink from a plastic water bottle and casually toss it in the trash, it can stay on the planet approximately 450 years?⁵ Even when you recycle, the complex nature of recycling doesn’t guarantee your plastic bottle will make it through the process. Americans purchase about 50 billion water bottles per year, averaging 13 bottles a month for each of us. By using a reusable water bottle, you can save an average of 156 plastic bottles annually.⁶

“But I don’t like the taste of water!” It may take time, but eventually you will. Add a little more each day, and eventually your body will feel so fantastic fully hydrated that you will have water cravings. In the meantime, you can visit the dining hall in the morning and add lemon, lime, berries, watermelon, cucumbers, or whatever taste you enjoy that will add a little healthy flavor to the water.

While water is undeniably the healthiest beverage you can drink, it is unrealistic to assume that is all you will drink. Be careful to minimize your soda intake, as most sodas are loaded with sugar or artificial sweeteners (which can be even worse than sugar). And unless you are squeezing your own fruit juice, you are also likely drinking a lot of sugar. Many fruit juices sold in supermarkets contain only a small percentage of real fruit juice, and have added sugar and other unhealthy sweeteners like high-fructose corn syrup. A 12-oz glass of orange juice can contain up to 9 teaspoons of sugar, about the same as a 12-oz can of Coke! Hot or cold herbal teas are a wonderful addition to your diet.

Exercise

Many people exercise to maintain or lose weight, but weight loss is only one potential benefit of exercise. Regular exercise can improve the quality of your sleep, strengthen your bones, increase your energy levels, and reduce your risk of high blood pressure, diabetes, and even some forms of cancer.⁷ Regular exercise is key to living a long, healthy life.

There are three basic types of exercise—flexibility, strength training, and cardiovascular.

1. Flexibility is the range in motion of the joints in your body, or the ability for your muscles to move freely. Without adequate flexibility, daily activities can become difficult to do. Stretching increases your body’s flexibility, improves circulation, and sends more blood to your muscles. Just a few minutes a day of deep stretching can have a powerfully positive impact on your health. Yoga and Tai Chi are other wonderful ways to improve your flexibility.
2. Strength is the body’s ability to produce force. Strength training helps improve muscle strength and muscle mass, which will become increasingly important as you age. Increased muscle helps your body burn calories more efficiently. Strength training also helps maintain bone strength. In addition to lifting weights, other ways to build strength include push-ups, pull-ups, squats, lunges, and yoga.
3. Cardiovascular is the body’s ability to use oxygen efficiently during exercise. As one’s ability to use oxygen improves, daily activities can be performed with less fatigue. Great cardiovascular modes of exercise include jogging, swimming, biking, and HIIT (high intensity interval training). HIIT is short bursts of intense activity followed by a rest period. With HIIT, you can squeeze a lot of benefit into a short period of time. Click here for an example of HITT workouts(opens in new window).

Research indicates that regular aerobic exercise can support memory and cognition. In these studies, aerobic exercise generally increases the number of new neurons created in the brain’s memory center and also reduces inflammation.⁸ Inflammation in the brain may contribute to the development of dementia and other neurodegenerative conditions. It might be good timing to take a jog before you sit down to study for a test!

It’s important to move throughout the day, and every day. Aim to exercise for 150 minutes a week. You don’t have to be the king or queen of CrossFit; it’s the daily movement that is most important. While it is best to integrate all three types of exercise, the best exercise is the one you will actually do. Find and commit to a form of exercise you will enjoy.

EXERCISE

Regular Exercise: Health for Life

The importance of getting regular exercise is probably nothing new to you. The health benefits are well known and established. Regular physical activity can produce long-term health benefits by reducing your risk of many health problems, such as heart disease, cancer, and diabetes, and it can also increase your chances of living longer, help you control your weight, and even help you sleep and think better.

As a busy college student, you may be thinking, I know this, but I don’t have time! I have classes and work and a full life! What you may not know is that—precisely because you have such a demanding, possibly stressful schedule—now is the perfect time to make exercise a regular part of your life.

Getting into an effective exercise routine now will not only make it easier to build healthy habits that you can take with you into your life after college, but it can actually help you be a more successful student, too. In addition to keeping your heart healthy, helping with weight loss, and helping you live longer, regular exercise can also improve your mood and help keep depression and anxiety at bay. Exercise is a powerful tool for stress management and improving one’s mental health and memory—all of which are especially important when you’re in school.

The good news is that most people can improve their health and quality of life through a modest increase in daily activity. You don’t have to join a gym, spend a lot of money, or even do the same activity every time—just going for a walk or choosing to take the stairs (instead of the elevator) can make a difference. Studies continue to show that it’s never too late to start exercising and that even small improvements in physical fitness can significantly improve overall health.

You can be successful with the inclusion of an exercise regime in your new life, but it is very important to find an activity that you like. Setting a schedule is advisable for success in your program. Also, doing a variety of activities will result in less boredom, and incorporating fun activities with family and friends can be very encouraging. The Maverick Activities Center (MAC) offers a wide range of exercise options from free-play sports, exercise equipment, swimming, indoor track, and more. Getting involved in intramural sports can also increase your activity level while meeting some social needs. Also, you will have the opportunity to walk on campus to contribute to your exercise activity, so don’t be so concerned with finding the closest parking spot available.

Being Active Throughout the Day

In addition to formal exercise, there are many opportunities to be active throughout the day. The more you move around, the more energy you will have. The following strategies can help you increase your activity and energy levels:

• Walk instead of drive whenever possible
• Take the stairs instead of the elevator
• Work in the garden, rake leaves, or do some housecleaning every day
• Park at the far end of the campus lot and walk to class
• Take regular breaks from your computer and desk to stand up, stretch, and walk around

ACTIVITY : WORKOUT OR WORK IN?

Workout or Work in?

Fitness expert Paul Chek says that the best workout is the one that you will do repeatedly.

• What is your favorite exercise or exercise routine?
• How often do you like to do it?

Paul Chek also has a concept of working out vs. working in. A workout is a strenuous exercise session like weightlifting, sprinting, or intense cardio. Working in, on the other hand, is doing more gentle, energy-building movement and exercise; it’s not energy depleting but energy generating. Examples of working in include yoga, tai-chi, qi gong, stretching, and walking.

• How much working out do you need?
• How much working in?

Toxins

We live in an increasingly toxic world. Since the Industrial Revolution, we have released thousands of man-made chemicals into the environment. These chemical toxins are in our food (pesticides, conventional fertilizers), in food packaging, in household products, and in our personal care products. Many of these chemicals have been linked to infertility, asthma, migraines, ADHD, and cancer.

The complicated thing about these chemicals is that their effects can take years or even decades to appear. The chemicals build up over time and they interact with each other, which can result in problems that are not considered by “single chemical” testing (which is the majority of the limited testing that is done).

Now the good news—there are simple things you can do right now to limit the amount of toxins in your environment. First, it is best to avoid any products with “artificial colors” or “fragrance.”

• Artificial colors: Synthetic dyes like Yellow 10, Blue 1, and Red 28 may contain carcinogens and neurotoxins and can be absorbed by your skin and go directly into your bloodstream.
• Fragrance: Have you ever walked down the cleaning and laundry soap aisle and been assaulted by so many fragrances you couldn’t get to the next aisle fast enough? Claiming trade secrets, companies don’t have to tell us what’s in “fragrance,” which can include highly toxic ingredients, hormone disruptors, and carcinogens. Fragranced products come in the form of soaps, cleaners, air fresheners, hand sanitizers, laundry detergents, and personal care products. Studies have repeatedly shown that the synthetic fragrances and other toxic chemicals included in these products are causing a range of health problems.⁹

There is a long and ever-growing list of common chemicals to avoid, but it’s hard to remember the names when you are shopping. That’s where a handy app like Healthy Living from the EWG comes in.

Simply scan the bar code of any products you use and learn about any potential health hazards.

"Many Americans are surprised to learn that the ingredients in their makeup, shampoo and body lotion are largely unregulated and, in some cases, harmful to their health. The fact is that companies can put potentially dangerous ingredients into the products they sell without ever having to prove they are safe.”

— Heather White, Environmental Working Group Executive Director

Your skin is your largest organ, and in seconds will absorb what you put on it. It’s important to be wary of conventional skin care products that could potentially leak toxins into your body. Think of your skin as one giant mouth. If you wouldn’t eat the ingredients in your products, think twice before applying them to your skin.

ANALYSIS QUESTION

Are your eating and sleeping habits currently affecting your ability to have a super-successful college experience? Describe the health and wellness changes a commitment to eating clean and sleeping well will bring about, and how you will benefit in the short and long term.

If You Need to Lose Weight

If you need to lose weight, don’t try to starve yourself. Gradual steady weight loss is healthier and easier. Try these guidelines:

1. Check your body mass index (BMI) to see the normal weight range for your height (see “Additional Resources” below for more information).
2. Go to choosemyplate.org(opens in new window) [www.choosemyplate.gov] for help determining your ideal caloric intake for gradual weight loss.
3. Set your goals and make a plan you can live with. Start by avoiding snacks and fast foods. Try to choose foods that meet the guidelines listed earlier.
4. Stay active and try to exercise frequently.
5. Keep a daily food journal and write down what you eat. Simply writing it down helps people be more aware of their habits and motivated to eat better.
6. Visit the student health center on your campus and ask for more information about weight loss programs.
7. Remember, no one plan works for everyone. Visit the online resources listed later for a variety of approaches for weight loss.

Avoiding the Freshman Fifteen

The “freshman fifteen” refers to the weight gain many students experience in their first year of college. Even those whose weight was at an appropriate level often gained unwanted pounds because of changes in their eating habits.

Start by looking back at the boxes you checked in the Nutrition Self-Assessment. Be honest with yourself. If your first choice for a snack is cookies, ice cream, or chips, think about that. If your first choice for lunch is a burger and fries, have you considered other choices?

Tips for Success: Nutrition

• Eat a variety of foods every day.
• Take a multivitamin every day.
• Take an apple or banana with you for a snack in case you get hungry between meals.
• Avoid fried foods.
• Avoid high-sugar foods. After the rush comes a crash that can make you drowsy, and you’ll have trouble paying attention in class. Watch out for sugary cereals—try other types with less sugar and more fiber.
• If you have a soft drink habit, experiment with flavored seltzer and other zero- or low-calorie drinks.
• Eat when you’re hungry, not when you’re bored or just because others are eating.
• If you find yourself in a fast food restaurant, try a salad.
• Watch portion sizes and never “supersize it”!

Eating Disorders

The most common eating disorders are anorexia, bulimia, and binge eating.

Anorexia is characterized by excessive weight loss and self-starvation. The individual usually feels “fat” regardless of how thin she or he becomes and may continue to eat less and less. If your BMI is lower than the bottom of the normal range, you may be developing anorexia.

Bulimia is characterized by frequent binge eating followed by an attempt to compensate for or “undo” the overeating with a behavior such as self-induced vomiting or laxative abuse.

Binge eating disorder is characterized by frequent binge eating without compensatory behavior to “undo” the overeating. Binge eating usually leads to weight gain and eventual obesity.

More than ten million Americans suffer from an eating disorder. The causes are complex, and the individual usually needs help to overcome their obsession. Eating disorders hurt one’s health in a variety of ways and can become life threatening. The signs of a possible eating disorder include the following:

• Eating secretly when others can’t see
• Having a strong fear of being overweight or gaining weight
• Only eating a limited number of foods
• Exercising obsessively
• Lacking a monthly menstrual period

Getting Help for Eating Disorders

Don’t feel ashamed if you obsess over food or your weight. If your eating habits are affecting your life, it’s time to seek help. As with any other health problem, professionals can provide help and treatment. Talk to your doctor or visit your campus student health center.
