Nutritional Balance

Nutritional balance is one of the four steps (a nutritionally balanced diet, adequate physical activity, regular sleep hours, and managing daily stress) toward healthy living. In recent years, many studies have shown that it is increasingly difficult for most people to maintain a healthy weight, because they do not understand the value of macronutrients, the benefits of micronutrients, and the difference between empty calories and nutrient-dense calories. The secret of staying fit and healthy depends on dietary energy consumption, which consists of nutrient-dense foods and is based on gender, age, weight, height and physical activity levels.  

          The energy required by the body is the number of calories specified to maintain optimal health by meeting daily calorie recommendations. It does not matter if a person needs to gain, lose, or maintain body weight, the first question that comes to mind is: “How many calories does the person need daily?” The estimated energy requirement (EER) is the normal dietary energy consumption that is calculated to maintain the energy balance (Dunfold & Doyle, 2015). EER is based on gender, age, weight, height and physical activity. The daily intake of calories can be calculated by app or software. There is another method. It is very simple but it is the least accurate way to estimate the individual daily energy intake in adult males and non-pregnant females based on gender, weight in kilograms, and level of activity. Table 1 provides this information (Dunfold & Doyle, 2015).

Table 1. Estimating Daily Energy Need for the General Population

Level of Activity	Energy expenditure – females (kcal/kg/d)	Energy expenditure – males (kcal/kg/d)
Sedentary (Activities of daily living ADL)	30	31
Light activity (ADL + walking 2 miles per day or the equivalent)	35	38
Moderate activity (ADL + moderate to heavy exercise 3 to 5 days per week)	37	41
Heavy activity (ADL + moderate to heavy exercise on most days)	44	50
Exceptional activity (ADL + intense training)	51	58

According to the Centers for Disease Control and Prevention, moderate-intensity aerobic activity for at least 2 hours and 30 minutes a week can lower the risk of developing cardiovascular disease, type 2 diabetes, and metabolic syndrome. Moderate intensity activities are those that increase the heart rate. The body uses more oxygen and burns three to six times as much energy per minute as when the body is at rest (Dunfold & Doyle, 2015).

For example, a 135 lb (61 kg) moderate active female needs approximately 2,260 kcal daily to maintain an energy balance (37 kcal/kg x 61 kg = 2,260 kcal). When we know the daily caloric intake, we can calculate the daily amounts of macronutrients. Carbohydrates, protein, and fat are all can be part of a healthy diet if they are balanced. 

 

Carbohydrates

            According to The Dietary Guidelines for Americans, carbohydrates intake should be between 45 and 65 percent of the total daily calories for healthy adults. There are two forms of carbohydrates: simple and complex, which are determined by their chemical structure. Simple carbohydrates are digested quickly by the body and increase blood sugar levels very quickly after consuming them. The digestion of complex carbohydrates happens slower because it takes longer for the body to break down complex carbohydrates into simple sugars. Complex carbohydrates provide more energy over a longer period of time. Both types of carbohydrates provide energy for the exercising muscles. If you are an athlete, you need between 55 and 60 percent of your total daily calories to come from carbohydrates to boost glycogen stores. For an intense workout, the consumption of carbohydrates (preferably low glycemic carbohydrates: oats, yams, brown rice, 100% whole grains) should be 2 to 4 hours prior to exercise to replenish the glycogen store, which is an extra source of fuel for the body, and immediately after exercise 1.5 g/kg/h (Dunfold & Doyle, 2015).

Protein

            There are two main types of protein: complete and incomplete. They are identified by the food source as either animal or plant-based proteins. There are several exceptions. Some plant-based foods, such as quinoa and soy, are examples of complete protein. According to The Dietary Guidelines for Americans, protein intake should be between 10 and 35 percent of the total daily calories for healthy adults. The body can use protein for energy when calories are insufficient, or as anabolic processes for building muscle mass. If you are an athlete, you need to be in a positive nitrogen balance to avoid the loss of lean muscle mass. The recommended daily protein intake for athletes depends upon activity levels and types of exercise (endurance or strength). There is an “anabolic window”, which is the first two hours post-exercise, when protein synthesis takes place. The maximum amount of protein synthesis after resistance training is 25 g during the first two hours after exercise (Dunfold & Doyle, 2015).  

Fat

Fat is an important source of fuel for light-intensity to moderate-intensity exercise, such as brisk walking, jogging, hiking, cycling, dancing, and recreational swimming. According to The Dietary Guidelines for Americans, fat intake should be between 20 and 35 percent of the total daily calories for healthy adults. These fats should include “good” fats, which are essential fatty acids EPA and DHA and are found in fish, flax, avocados, and olive oil, and normal fats from meat and dairy sources. Intake of trans fatty acids should be avoided. Athletes should not be on a low-fat diet and their fat intake should be determined based on total calories, carbohydrates and protein intake (Dunfold & Doyle, 2015). 

Hydration

        Water is not an energy source and it has zero caloric value, but it plays an important part in our diet. Water helps the body digest and absorb foods and eliminate the body’s digestive waste. An average amount of water intake for adults is approximately 2,350 mL/d; this number is based on the consumption of beverages and other food sources. If you exercise intensely for more than one hour, a beverage with electrolytes such as a sport drink is highly recommended. During exercise, water loss happens through sweating. The basic rule to regulate water balance after physical training is 1.5 L per each kilogram of body weight lost after exercise (Dunfold & Doyle, 2015).

 Returning to the example of 2,260 kcal daily for moderately active female, Table 2 summaries the daily intake of macronutrients based on daily recommendations for carbohydrates, protein, and fat. 

Table 2.  Daily Caloric Intake of Macronutrients for 2,260 kcal/d

Macronutrient ranges	Low  (kcal/day)	High (kcal/day)
CHO	1017	1469
PRO	226	791
FAT	452	791

 

 Supplement intake 

The federal government’s 2015-2020 Dietary Guidelines for Americans established that, “Nutritional needs should be met primarily from food.” Some people may be considering some dietary supplements. It is important to talk to your healthcare provider about your best interests in terms of dietary supplements and what may be best for your health. 

 

Fish oil supplements 

Omega-3 fatty acids are important in preventing and managing heart disease. Omega-3 fatty acids may provide some heart-healthy benefits: lower blood pressure, decreased triglycerides, and slowed development of plaque in the arteries. Foods such as salmon, mackerel, herring, sardines, lake trout, and tuna are the best source of omega-3s. Fish oil supplements are a good substitute for individuals who do not like fish. The American Heart Association states that taking up to 3 g of fish oil daily in supplement form is safe. 

 

Magnesium supplements

Magnesium is an important mineral, which helps to keep blood pressure in the normal range, strengthens bones, and keeps the heart rhythm steady. Dietary references intakes (DRI) for magnesium are 310 mg/d (females, ages 19-30); 320 mg/d (females, ages 31 and above); 400 mg/d (males, ages 19-30); and 420 mg/d (males, ages 31 and above) (Dunfold & Doyle, 2015). 

In the end

Everything comes down to a person’s style of eating. It is not just what kind of ingredients we choose; it is also the way that we eat our food. In the modern world, we are always in a rush. We eat breakfast during our morning commute. We eat lunch at our work desk. We eat dinner in front of the television watching the news or using one of our many electronic devices. We have to deal with stress during our mealtimes. We are constantly in “the fight-or-flight” stage. This is the body’s response to threats or danger, which is controlled by the sympathetic nervous system. This response causes the heart rate to increase and also elevates blood glucose concentration, but it slows down the digestion process. Too much sympathetic dominance may inhibit our ability to absorb nutrients from food, cause us to become overweight, and result in poor blood sugar regulation, exhaustion, and insomnia. 

We forgot that our ancestors used to say prayers before mealtime. I would like to look at holistic part of this tradition, rather than the religious aspect of this custom. Prayer and deep breathing techniques help to slow down the heart rate. Deep breathing before consuming food will not only slow down the heart rate, but it also brings more blood flow to the digestive tract, which helps with the absorption of nutrients. We need to get in “the rest and digest” state before and during our mealtime.  Next time you eat a balanced meal, don’t forget to be in the parasympathetic (rest and digest) mode.

The Myth of L-carnitine

The Myth of L-carnitine Supplements

Invest in Our Health Today for a Brighter Future

       

                    Phrases such as a good-looking couple, attractive people, a handsome man, and a gorgeous woman are common in our language. Have you ever heard other phrases like, wonderful lungs, a magnificent heart, and graceful bones? I do not think so.  These phrases sound very strange and we do not talk this way. Most of the time, we concentrate on superficial beauty and do not care about inner beauty.

When we buy a new car, we invest money in it and we want to keep it in good condition for ten years or longer. We know that our car will look better and last longer not only with frequent washes, but also with regular oil changes and mileage services.

       When it comes to our future, one day we all start thinking about our retirement and saving money for later. We dream that some day we will be retired and we will have a lot of free time. We will start travelling more and doing many more fun activities. However, we will only be able to do these things if our health is in a good shape. Are we investing in our health today?    

       According to the American Heart Association, preventing heart disease means choosing healthy living now to give us a better chance to stay in a good shape for the rest of our lives. Lack of exercise, poor diet, and unhealthy habits such as smoking, excessive alcohol use, lack of sleep, and too much stress can take a toll over the years and cause health problems in the long run. No matter how young or old we are, we need to keep our body healthy during each decade of our life.

       A study published in the journal Obesity Research & Clinical Practice found that during the present time, it is more difficult for people to maintain their body weight than it was 20 to 30 years ago, with variables such as food intake and exercise remaining unchanged. In the present day, people are about 10 percent heavier than people were in the 1980s.  Scientists are still examining possible causes for this fact. Jennifer Kuk, a professor of kinesiology and health science at Toronto’s York University, states three factors which differentiate present society from 1980s. First, people are now exposed to more chemicals in the environment. Second, people consume elevated levels of prescription drugs such as Prozac and other antidepressants. These drugs can cause weight gain. The third reason is due to gut bacteria. Many animal products are treated with hormones and antibiotics, which may cause some changes to intestinal micro flora; this leads to weight gain, as well.

Four Easy Steps 

       It is hard to change these three factors of modern life. However, we can try to adapt our life to the modern world. We can do it by following four simple steps: a nutritionally balanced diet, adequate physical activity, regular sleep hours, and managing daily stress.

  

Nutritionally Balanced Diet

The right food can reduce the risk of heart disease and stroke. This food should be low in saturated fat and sodium. Fruits and vegetables, fiber-rich whole grains, fish, nuts, legumes and seeds are important components of a healthy diet. We can control the ingredients by cooking from scratch. Homemade meals should not be complicated and require a minimum time to prepare. Grilling is a good option for cooking meat. A good addition to grilled meat can be a salad or steamed vegetables.

Adequate Physical Activity

Routine physical activity and reduction in a sedentary lifestyle can improve physical fitness, lower many heart disease risk factors such as (bad) LDL cholesterol levels, increase (good) HDL cholesterol levels in the blood, and control high blood pressure. Any aerobic exercise, in which the heart beats faster and the body uses more oxygen than usual, will benefit heart health. Exercise does not always mean going to the gym. It could be jogging outside or even taking a brisk walk. We should also remember that physical activity is any kind of activity, not just exercise. We can stay more active by avoiding an elevator and taking stairs instead, parking the car farther away and walking greater distances to a store, vacuuming the house more often, and engaging in other similar activities.

Regular Sleep Hours

According to Dr. Sachin Patel, who is the founder of The Living Proof Institution, sleep helps our body to heal and repair itself. Our society thinks wrongly that cutting sleep hours will provide more time for activities. Lack of sleep, especially on a regular basis, is associated with long-term chronic medical conditions like heart disease, diabetes, and high blood pressure. Regular sleep hours help our body to recharge and give us more energy to function well during the day. Regular sleep hours mean going to bed and waking up at the same time, including weekends as well. It sounds impossible but it will provide great results if you are willing to try.

Managing Daily Stress

Stress can contribute to high blood pressure and other cardiovascular risks. Some people deal with stress by drinking alcohol, smoking, or overeating. These are not healthy ways to manage stress. Learning how to manage stress is the most difficult step, in my opinion. If we learn how to resolve problems and manage our anger or frustration, we will improve our emotional and physical health. The hardest thing for me to learn was that my good mood or positive day depends on me and not on circumstances around me. We cannot change the behavior of other people toward us; rather, we need to change our attitude towards life. The easiest way to calm down is to take three deep breaths, instead of having an emotional response. These breaths help to slow down the accelerating heart rate and provide some time for thinking. They allow us to think of what can be done to get things under control.

Four Steps Challenges

Four steps, which include a nutritionally balanced diet, adequate physical activity, regular sleep hours, and managing daily stress, will lead to a healthy lifestyle, which should become our daily responsibility. The hardest thing to do is to execute this plan. It is an individual process. Some things which work for me may not work for others. It requires some time for searching and adaptation. Some steps like stress management and adequate physical activity could be combined in one.  For me, it is a long walks on a nature trail. The hardest thing is to find the way to follow these four steps daily and commit to a new healthy lifestyle for a long time.

Do you want to challenge yourselves and invest in your health today? Are you willing to try these four steps? I would like to believe that your answer is yes. If your answer is yes, I know that you will be successful in your wellness journey.

Health, Happiness and Harmony
