Nutrition and the Immune System
Good nutrition will help strengthen your immune system and keep it strong. Poor nutrition results in a weakened immune system. A weakened immune system results in infection and illness. Infection and illness may cause a decrease in your appetite and negatively affect your digestion and absorption of nutrients which, in turn, results in malnutrition and weight loss. More malnutrition and weight loss further weaken the immune system.4 This cycle of malnutrition and increased infection/illness can be avoided if you eat well. You do not need to take a college course in nutrition to learn how to eat well. A few simple facts and eating hints will help you in managing and meeting your proper nutrition.
What Your Body Needs
Proper nutrition is important to your everyday health and well-being. Your body is constantly working twenty-four hours a day, seven days a week. During the day your body is busy making energy to help your muscles work, eliminating waste, digesting food, regulating your body temperature and performing numerous other activities. At night when you are asleep your body continues to work but at a slower rate. In addition, specialized functions such as healing, growing, and replenishing are occurring.
Your body needs energy in the form of food to perform these functions. And, these functions require energy (calories) in the form of proteins, fats, and carbohydrates. In addition, the body requires certain substances such as vitamins, minerals and water (yes, water!) to help perform all its functions.
Your body becomes weak and susceptible to illness without high quality sources of food. Chronic illness like HIV-infection or an AIDS diagnosis places extra demands on your body and therefore requires that you pay special attention to the quality, variety, and quantity of food you eat.1
Protein
Protein is vital to optimal health. All parts of your body need protein - the brain, heart, liver, kidney, muscles, etc. Proteins are made up of substances called amino acids. Amino acids are needed to help perform many of the biological functions in your body. Without them, these functions could not happen and very poor health or even death could occur. For example, protein is needed to make antibodies which help prevent infection and disease from microbes like bacteria. Proteins also transport oxygen and nutrients in the blood and are essential to the clotting of blood, the formation of scar tissue and muscle growth. When you do not eat adequate amounts of protein every day, these functions become impaired, and cells, tissues, and muscles are not replenished.
Lack of protein in the body results in catabolism. Catabolism is when the body begins to "break itself down" in order to get the nutrients it needs. Its the bodys way of ensuring you stay alive. If you do not get enough protein, your body will undergo catabolism to keep your bodys biological functions running. You begin to lose muscle mass (wasting) since muscle tissue contains the most protein. Catabolism also weakens your immune system.
It is recommended that a person living with HIV or AIDS get between .8 grams to 1.0 gram of protein per pound of body weight.3 For example, if a person weighs 150 lb. he should get between 120 grams (.8x150) to 150 grams (1.0x150) of protein a day. Generally, one cup of a dairy product is equivalent to 8 grams of protein and one ounce of meat contains approximately 7 grams of protein. Product labels will also indicate amount of protein.
Protein can be found in meat, poultry, fish, eggs, seafood, beans (pinto, black, kidney, garbonzo, lentils and peas), diary products, and vegetables. Soy milk, tempeh, and tofu are also excellent sources of protein, especially if you dont or are unable to eat animal sources of protein. You can also supplement your diet with protein shakes. Many of these commercial supplements are fortified with vitamins and minerals and are simple to prepare. They can be used to increase the protein in your diet, as a snack , or to supplement a meal.
Carbohydrates
Carbohydrates or "starches" are broken down in the body into a sugar called glucose. Glucose supplies the cells in your body energy in order to function. Carbohydrates are found in pasta, whole grains, cereal, rice, beans, lentils, peas, nuts, fruits, and vegetables.
Fats
Fats also supply the body with energy and help with the digestion of certain vitamins and minerals. There are saturated and unsaturated fats. Saturated fats are found primarily in animal products, and unsaturated fats are in both animal and vegetable products. Animal fats look gristly and can be seen on the outer edges of pork chops, steaks, and other red meats. Animal fat is also found in the skin of poultry such as chicken and turkey. Vegetable fats are found in nuts (almonds, peanuts, etc. ), seeds (safflower, sunflower, flax), and beans (soy). Because of our "body conscious" society, fats have received a bad "rap." In reality, the body needs fat. There are substances called "essential fatty acids" (EFAs) that are fats which help in certain biological functions and which help protect your body from harmful substances called "free radicals." Free radicals have been associated with cancer. EFAs are mostly found in nuts and seeds, especially safflower and flax seeds or oils.

Calories if you do not eat enough food to meet your caloric needs you will start to lose weight and strength
Take a multi-vitamin one to two times a day
Protein Protein helps support immune function. If you do not eat enough you could lose muscle mass and strength
Take one B-complex pill a day
Fluids water is essential to help prevent dehydration and assist with bodily functions
Vitamins and Minerals
Vitamins and minerals are necessary for proper bodily functions and disease prevention. Vitamin and mineral deficiencies can cause certain diseases and illnesses. For people with HIV it is recommended to take a daily broad-based multiple vitamin-mineral supplement. The key word here is supplement, not replacement. Vitamin and mineral supplements should not take the place of eating well. There are many compounds in food that are necessary to maintaining optimal health and are not found in supplements. A supplement pill which provides 100% to 200% of the recommended daily allowance is fine. In addition you may want to consider supplementing zinc and selenium, as research has shown that HIV-positive people tend to have zinc and selenium deficiencies. Do not take mega doses of vitamins without consulting your doctor and/or nutritionist. Due to their toxicity at high levels, mega doses of certain vitamins can result in side affects such as nausea, diarrhea, and headache, and may even interact with some of the prescribed medications you are taking.1 Unfortunately, the science of supplementation and nutrition is new and further study is needed prior to making definitive therapeutic claims.
Water
One thing you cant have too much of is water. Your body uses a lot of water each day. Water helps to detoxify your body, assist with transport of nutrients and other substances, and regulate your body temperature and weight. Try to drink at least eight cups of water a day. Its a good idea to avoid tap water whenever possible. If you are out hiking or in the wilderness, dont drink the river water. The water may look "sparkling clean", but it is full of microbes that can wreak havoc on your gastrointestinal tract. If you have diarrhea, vomiting or fever drink plenty of water or other liquids like ginger ale, juice, broth, sports drinks (Gatorade), etc. to replace the fluids you lose when experiencing these symptoms.1,2,
Calories
Calories refers to the term used to measure the energy in food. We need a minimum level of calories every day to maintain our body weight. The amount of calories necessary will vary from person to person, depending on their age, weight, physical activity, and health. To make sure you are getting enough calories eat four to six small, nutritiously sound meals a day or three medium sized meals with three to five healthy snacks. Nutritional liquid supplements (Ensure, Advera, etc.) can be used as snacks between meals or with a meal in order to boost your daily caloric goals. Talk to your nutritionist or doctor to recommend one to you.
Servings
A good way to make sure that you are eating a well-balanced diet is to eat a variety of fruits, vegetables, grains, meats and dairy products and to drink plenty of water. One source of food, no matter how nutritious it may be, will not give you all the essential nutrients for optimal health. A serving is usually a medium sized piece of fruit (pealed or washed) one slice of bread, 1/2 a bagel or muffin, five to eight crackers, two eggs cooked any style.1 Read the nutrition labels on food items. The nutrition label will also indicate the amount of protein per serving. This can be helpful if you are trying to increase your protein uptake. Use the chart below to help you figure out a typical serving for common food items.1,4
Serving Recommendations:
1. Fruits-- A Minimum of Four Servings a Day: for vitamins and minerals, fiber and carbohydrates
2. Vegetables-- A Minimum of Five Servings a Day: for vitamins and minerals, fiber, carbohydrates, and protein
3. Breads, cereals, pastas and grains (rice) -- A Minimum of Ten Servings a Day: for carbohydrates, fiber, protein, minerals and vitamins
4. Meat, poultry, and fish -- A Minimum of Three Servings a Day: for protein, fats, vitamins and minerals
5. Milk, cheese, and yogurt -- A Minimum of Three Servings a Day: for protein, fats, vitamins, and minerals

Nutrition Suggestions for People Living with HIV1,3,4
Food Safety
Food safety must become a very important part of your life. You cannot be too cautious when it comes to food safety and handling. Preventing food-borne illnesses requires strict, habitual cleanliness.
You must take extra precautions to avoid getting sick because your immune system may not be working at full strength. For example:2,3,1
At the grocery store:
At home:
Nutrition Strategies for Common Problems1,3,4
You must eat in order to maintain your strength, stamina, and weight. If your appetite continues to diminish, consult your doctor. He or she may be able to prescribe medications that will stimulate your appetite.
If cramps accompany your diarrhea avoid foods which cause gas such as beans, broccoli, cabbage, and cauliflower. If cramps or other severe pain accompanies your diarrhea or if the diarrhea gets worse, is bloody, or last more than five days contact your doctor. Unchecked diarrhea can cause serious dehydration and electrolyte imbalances. Your doctor can prescribe medications to avoid these from happening.
Changing Your Diet
Changing your diet may be one of the best things you can do to help you live a more healthy lifestyle. As explained early in this chapter, nutrition is very important to optimal health and optimal health is your goal. You must determine if your current eating habits support you and if not what you want to change. A good way to do this is to keep a food journal for a week to get a snapshot of your eating habits and the foods you eat (see Appendix for sample).4
Record in your food journal what you eat and drink and the time you eat. For example, an entry would read:
Daily Menu/Food Journal
Day: Monday
|
|
|
|
|
8:30 a.m. -- two scrambled eggs, 1 slice of toast w/ butter and jam, a glass of milk
|
12:30 p.m. -- Turkey Sandwich (two slices of wheat bread, 2 slices of Swiss cheese, 2 slices of turkey, lettuce, tomato, pickles and onions, mayonnaise and mustard), 1/2 cup of macaroni salad, a bowl of tomato soup (about 2 cups) and glass of juice (grape).
|
6:15 p.m. spaghetti and meatballs (full plate of spaghetti and six meatballs), salad (lettuce, tomato, chopped carrots, and red onions) with vinegar and oil dressing, three slices of French bread, a glass of water.
Two chocolate chip cookies and three scoops of vanilla ice cream. |
|
|
|
|
|
10:45 a.m. -- apple
|
2:15 p.m. -- 1 bag of Popcorn w/ butter and a soda
|
8:40 p.m. --Cheese and crackers ( about 10 crackers and ten bite size pieces of monteray jack cheese and a glass of orange juice
|
When making entries for vegetables guess whether it is a 1/2 cup, 1 cup, etc. Make sure to provide detail on what you eat. For example, a turkey sandwich to one person may be two slices of turkey and bread, yet to someone else it may include cheese, lettuce, tomato, sprouts, etc. A more accurate picture of your nutritional intake is provided by the detail you write in your Food Journal. The more detailed you can be the better. You may find it easier to make your entries right after you eat as opposed to the end of the day.
After a week, review the journal to see if you are eating:
Also review the journal to see:
This information will help you see if you are eating the minimum number of servings to sustain optimal health, whether you are eating enough, if what you are eating is healthy and nutritious, and if you are drinking plenty of water and other healthy fluids. Once you have reviewed the journal you can them decide if there are any changes you want to make.
If you decide to make changes, write down all the reasons why you want to make the changes. Changing ones diet can be difficult, so this has to be something you want to do. If you cant come up with any reasons why you want to change your diet, then it is not a good time to start this process. This is okay, because all change happens in time and on time. Remember, be gentle with yourself, you may not be ready yet.
When you feel and know you are ready to start, start off slow.4 Pick one thing to work on. It is best to pick something that will be easy for you to accomplish. For example, after reviewing your journal you may notice that there are several changes you would like to make. You may notice that you dont eat enough, that your snack choices are mostly sweets, and that you very seldom drink water. If drinking more water is the easiest place to begin, then begin there or you may decide that you just want to eat more in general.
Once you have a starting point, you will develop a self-contract as outlined in Chapter One. Remember your contract should be specific. "I want to eat more" is not specific enough. You will need to plan out how you will accomplish eating more. This is a good time to get support from your health educator in planning out your objectives.
Changing your diet will require you to do some planning. For example, if you decided to "eat more" then you would want to plan how often, how much, when, and what you would be eating more of. The more specific you can be the more likely you will succeed. Lets follow a patient, who we will call Carol, as she puts together her plan to eat more.
Carol decides she wants to change her eating habits. After reviewing the food journal she kept for a week, she identifies several things she would like to change and decides to start with "eating more." Carol then writes down her reasons for wanting to eat more. She comes up with the following list:
Carol then sits down to write out her contract. She:
Carol then asks herself "Can I meet this contract?" She decides that she is "neutral" on her ability to meet it, so she adjusts it to read, "Eat two healthy snacks a day. Eat one in the morning at 11:00 a.m. while I watch the Price is Right and the second at 9:00 p.m. while I watch the Rosie ODonnel Show."
Carol made these changes because she had to arrange her snacks around her Crixivan schedule. Carol takes her Crixivan at 7:00 a.m., waits an hour (as prescribed - one hour before or two hours after meals) then eats breakfast around 8:00 a.m. She tries to eat her lunch by 1:00 p.m. every day, since she needs to take her Crixivan at 3:00 p.m. (8 hours after her first dose, two hours after her meal). So, eating her snack at 11:00 a.m. would work well. Carol normally eats dinner around 6:00 p.m. and her last dose of Crixivan is at 11:00 p.m., so the latest she could eat a snack would be 9:00 p.m. She normally doesnt eat after dinner, but since she faithfully watches the Rosie ODonnel Show she figured this would be a good reminder to eat her second snack.
Carol felt more comfortable with the new objective and posted it on her refrigerator and television to remind her. The next step Carol did was to plan what she would eat for snacks by making a weekly menu (see Appendix for sample). She then went out and bought all the food she would need on hand to make her snacks.

Snack Ideas -- Be creative, experiment with different food textures and tastes
|
|
Peanut butter spread on celery, a medium sized cherry almond scone and juice, milk or water
|
|
Granola, walnuts and oats mixed in applesauce, a half a bagel with butter and a glass of soy/skim milk or juice/water.
|
|
Fruit Smoothie-- two cups of skim/soy milk, 1 large banana, 1/4 cup granola, several strawberries, 1 tablespoon of soy protein isolate. Mix in blender. Delicious!
|
|
Yogurt (stir in your favorite fruit, nuts or granola) and a fruit filled bar or raisin bread
|
|
1 medium sized apple (skin pealed) with some almonds, a couple of slices of cheese, some crackers and a glass of water
|
Carol checked off her objectives on her contract as she met them. She took notes on both her successes and barriers. After a few weeks, Carol found that her appetite and energy increased and she slowly started to make her other meals more nutritious and hearty. Carol was successful at managing her nutrition changes, and of course she rewarded herself by learning something she always wanted to learn...yoga.
Your successes will depend on your desire to change, your readiness, and your clarity about what you will be changing. Remember to start slowly. As you experience success with managing your nutrition program you will begin to wonder why you never ate better before. This is normal. Reward yourself for your success and keep moving forward.
If you experience problems, use the problem solving methods described in Chapter One to help you work around them and find solutions. Above all be patient and consistent in your practice, if you need assistance with changing your eating habits call the Owen Clinic Nutritionist at 543-3995 or Health Educator at 543-2680.
