Cow’s Milk vs. Almond Milk

Megan Johnson McCullough/31 July 2023/ All MFN blog/

Milk has been a staple of the American diet for every generation. Children are told their bones will grow strong when they have a glass of milk. It is our first meal from our mother, but then becomes replaced by another form. For many years, the only type that existed was cow’s milk. Today, almond milk has become an alternative causing a debate questioning which is the better choice.

In the battle of cow’s vs almond milk, the winner might be a matter of personal preference. Here’s how they stack up:

Cow Milk

One percent low fat milk contains about 110 calories, 2% contains 130 calories, and whole milk has about 150 calories per cup. 90% of the world’s milk comes from dairy farms. There has been questioning about the cleanliness and humanity of this process. Some even argue that cow’s milk is not actually meant for human consumption. Milk is made up of lactose, which is the most common food allergy in the world. Despite all this, cow’s milk does have quite a bit of nutritional value. In just one cup of milk, there contains 305 milligrams of calcium. This is needed for bone health, our teeth, and blood health. Cow’s milk also has choline which is a nutrient that helps with memory, sleep, and muscle development. It also contains potassium and Vitamin D. The major downfall is that this milk is high in saturated fat. This is an important consideration for person’s with diabetes or heart disease.

Almond Milk

Almond milk generally contains fewer calories. Unsweetened almond milk has a mere 30 calories per one cup. The process of making almond milk is similar to brewing coffee. However, the final product does not contain the same amount of nutrients as whole raw almonds. Some of the calcium, fiber, and protein is lost in this process. Therefore, many almond milk products are fortified with nutrients to help make it look comparable to cow’s milk. Almond milk is naturally lactose free which can help those with digestive issues. It is also environmentally sustainable due to the major cultivation of almonds. Almond milk contains healthy Omega 3 fatty acids. This can help lower bad cholesterol levels.

When it comes down to the final winner, the decision is primarily based on a person’s dietary needs. For someone who is trying to lower their cholesterol and keep their blood sugar down, almond milk would be the winner. For someone who is active and still growing and developing, cow’s milk might be the winner. Again, this would all depend if a person is lactose intolerant. The world of milk has changed with many different varieties now available. A bowl of cereal just isn’t a bowl of cereal without milk, no matter what kind.

A new game changer has been the spark in attention for chocolate milk. Both traditional milk and almond milk can come in this tasty flavor too.

At the outset, one might question chocolate anything being beneficial to our health, and this beverage is normally a mixture of the milk type with cocoa and other sweeteners (sometimes even high-fructose corn syrup). A little higher in sugar and carbs then most might desire, but the benefits might override these factors. 1 cup has about 200 calories and 30 carbohydrates as well as 28% of the recommended daily intake (RDI) for calcium, 25% RDI for vitamin D, 24% for riboflavin, and 25% for phosphorus. All of these are great for bone health.

Avid exercisers and athletes have become fond of drinking chocolate milk because of its contribution to muscle recovery post-workouts. Here is where the carbs and sugar can actually be beneficially, and it is also important to remember that milk is considered a protein with all the essential amino acids. Studies have not proven the effects of chocolate milk are any better than any other type of recovery sports drink.

Including milk of any form in your diet can be great for you bones and hormones, but that is not the case for everyone. Some people have an intolerance to milk that can cause abdominal pain and bowel problems. A person that is lactose intolerant has a condition in which their small intestine doesn’t produce enough of the enzyme lactase. Lactase is needed to break down and digest dairy, so if you aren’t able to do so then discomfort can result. For some people irritable bowel syndrome (IBS) can be triggered by dairy products. This can result in stomach cramping and chronic diarrhea. In this case, milk should certainly be avoided. Some people are also simply allergic to milk. Their body treats it like a foreign substance. Children usually outgrow milk allergies by the age of three. Symptoms include itchy skin and hives after drinking. There are supplements that can help a person break down and digest dairy if they desire to have it. This way they don’t have to completely eliminate them.

As adults, we don’t always drink milk like we used to as kids. Maybe a little with cereal, oats, or coffee here and there, but overall, we don’t have it with dinner anymore. Milk is a tricky portion distortion problem for some people. Have you ever added more milk because you have a little cereal left? Have you ever thought cookies and milk sounded good and then you keep eating the cookies, so you keep drinking the milk with them? Sticking to drinking just once cup is out of the question many times. For kids, milk is certainly the better option versus soda or sugary fruit juice. Families buy gallons for their kids. There’s a type for everyone’s taste buds depending on what type you buy. Skim or 2% are the most popular options, but then again, some people even like buttermilk. Milk is great for our bodies, and well, chocolate milk makes it case, but not too convincingly. Let’s face it any excuse to add some chocolate to anything can be attractive. Our society keeps the cows busy, but certainly not by those who are lactose intolerant.

Balance: Control of Your Frame

Megan Johnson McCullough/23 June 2023/ All MFN blog/

Balance is the body’s ability to be pulled in the right direction at the right time. The central nervous system (CNS), composed of the brain and spinal cord, accomplishes this task for us. This system is in charge or activating and relaxing the needed muscles with precise timing. The CNS is overstimulated every second of our lives, but has the multitasking power to take in information, be able to process it, and then apply accordingly for the task at hand.

3 Parts

This information comes threefold from the eyes, ears, and sensors throughout the body. When it comes to balance, the eyes communicate what surface the CNS is working with. The vestibular apparatus, which is the inner ear, communicates where the head should be to the CNS. We also need our limbs, joints, and muscles for balance which our feet and skin take care of this communication to the CNS. All of this is signaled at once and has to be sorted and processed very quickly.

Stand up straight

The efficiency of this central nervous system’s information processing is what dictates whether a person has good balance or not. If a person were standing up and started to lean over the right, the right foot would tell the CNS that pressure to the right foot is increasing while the pressure to the left foot is decreasing. This shift is then “seen” by the eyes and the ears would become aware that they are not level with one another. Now those sensors in the muscles are told it’s time to wake up and pull the body back towards the left side until balance is achieved.

Practice

We can be proactive and help keep our balance be kept in good condition. Exercise fanatics often focus on aerobic and resistance work, neglecting balancing activities. Many don’t worry about their balance until it is noticeably lacking. Balance is a “use it or lose it” operation, in which the machine becomes rusty if left alone for a long period of time. After about age 30, the very muscles we use just to stand become weaker. With age, we slow down, and midlife can bring the onset of instability. Falls can occur and this can lead to hip fractures or serious injuries.

Balance is about control. We try to balance our checkbook and time but we also should make keeping our body in line a priority. Think about a toddler learning to walk. Once they are able to balance in the standing position, they have gained the control for movement. This involves body awareness.

We can practice our balance to keep the system sharp. This can be done be making the surface we stand on smaller. Standing on one foot is the most basic form of balance practice. You can change the surface by adding a dyno disk. You can squat down (bend down) on one leg pretending to pick something up. Different tools stimulate proprioception.

Reaction time

The reaction time of the central nervous is critical for keeping the body in balance. From a professional athlete to the average person, we can all benefit from this control. Think of a goalie in soccer. The better they are able to react to a ball, jump to one side, or balance to stop the ball without falling in the process, the better their performance. Falls and injuries with age are damaging to the body and our sense of independence. Stand tall, don’t sway, and balance your life physically and mentally for your health.

The Stress Factor

Megan Johnson McCullough/17 May 2023/ All MFN blog/

What lights a fire under you?? What grinds your gears, makes you angry, sad, worried, or STRESSED?? We each deal with the components of life differently, and our reactions to circumstances dictate our emotional well-being. Time, relationships, work, school, kids, family…. all these responsibilities can require a balancing act that seems impossible. But that’s life. And unfortunately, stress can have adverse effects on our health… especially weight.

Your body and mind are one and the same. When put under pressure, your brain kicks into a flight or fight mode. And guess what? Your body wants to use calories in its defense. As such, “Most of us become overeaters when we’re feeling a lot of pressure. This happens thanks to your fight-or-flight response, a.k.a. survival mode — once your body reaches a certain stress level, it does what it feels it needs to. In most cases, that means overeat.” ⁽¹⁾

Initially, adrenaline spikes in the body, making one feel less hungry. However, soon after cortisol takes over. Cortisol is the stress hormone. When activated, inhibition can go out the window. Here’s run down: “Because increased levels of the hormone also help cause higher insulin levels, your blood sugar drops and you crave sugary, fatty foods.”⁽¹⁾ Cheap, convenient, processed foods, are right there to answer the calling.

Here’s the catch: “Today’s human, who sits on the couch worrying about how to pay the bill or works long hours at the computer to make the deadline, does not work off much energy at all dealing with the stressor! Unfortunately, we are stuck with a neuroendocrine system that didn’t get the update, so your brain is still going to tell you to reach for that plate of cookies anyway.” ⁽²⁾

We have to learn to relax, sleep, and breathe. Many clients ask me what foods to turn to. Here’s what I found:·

Dark chocolate: Two studies of 95 adults showed that consuming dark chocolate reduced their cortisol response to a stress challenge.

Many fruits: A study of 20 cycling athletes showed eating bananas or pears during a 75-km ride reduced levels compared to drinking water only.

Black and green tea: A study of 75 men found 6 weeks of drinking black tea decreased cortisol in response to a stressful task, compared to a different caffeinated drink.

Probiotics and prebiotics: Probiotics are friendly, symbiotic bacteria in foods such as yogurt, sauerkraut and kimchi. Prebiotics, such as soluble fiber, provide food for these bacteria. Both probiotics and prebiotics help reduce cortisol.·

Water: Dehydration increases cortisol. Water is great for hydrating while avoiding empty calories. A study in nine male runners showed that maintaining hydration during athletic training reduced cortisol levels.⁽³⁾

Life’s demands throw us for a loop from time to time. Reassure yourself that patience is the key and that this too shall pass. Don’t let your negative thoughts take the wheel. Healthy choices outlast split second mistakes. Be kind to your BODY, even in it’s weak moments.

Lou Gehrig’s Disease: Death of the Nerve Cells

Megan Johnson McCullough/13 March 2023/ All MFN blog/

Motor neuron disease (MND), Amyotrophic lateral sclerosis (ALS), also called Lou Gehrig’s disease, causes the death of the neurons that control the muscle’s voluntary functioning. Lou Gehrig was a famous baseball player who was diagnosed with ALS. Overtime, the nerve cells progressively break down and die. At first onset, muscle twitching might start to occur coupled with weakness in the limbs, and slurred speech. Eventually, a person will no longer be able to control their ability to move, speak, breathe, or eat. This disease is fatal and there is currently no cure.

Fit PACE: Substance Abuse & Exercise

Megan Johnson McCullough/1 February 2023/ All MFN blog/

Research has shown the positive influence of exercise on alcohol use disorder (AUD) recovery as well as other drug-related substances. However, qualitative research has been missing regarding the influence of exercise on substance abuse disorders. In 2021, I performed a qualitative study involving interview and exercise journal data, which further validated the benefits of exercise during addiction recovery (specifically AUD). Most importantly, the results of the study showed how exercise can persuade the decisional balance a person has when working through the process of recovery. The benefits of exercise (pros) are better than the benefits of drinking (which are now cons). Another important theme participants expressed was that exercise does help recovery, but it should be a tool, not a replacement to other forms of treatment. Therefore, exercise shouldn’t replace strategies such as group meetings (e.g., AA or NA), cognitive behavioral therapy, or medications. Rather, exercise can compliment a comprehensive treatment program as a tool to maintain abstinence from alcohol and other substances, with the ultimate goal of avoiding relapse and reaching termination of the addiction. The intention of my study was to help medical and fitness professions better understand how persons connect exercise performance to their recovery process. This information also leads to better strategic planning programs for recovery, including exercise.

As a result of my research, I have developed the PACE Method to assist persons in recovery who are using exercise as a tool in order to combat not only relapse but also the threat of replacing one addictive behavior with another. One might replace exercise with the aforementioned forms of treatment, and in doing so, replace the psychology/physiology of their addictive habits with exercise performance. Even if exercise is considered “healthy”, in excess, there are consequences to the body. Currently the DSM-5 (Diagnostic and Statistical Manuel of Mental Disorders from the American Psychological Association) does not have diagnosis for exercise addiction. What is considered the appropriate/recommended, “normal” amount of exercise? Leaving that up to be self-determined, particularly to persons in recovery who are at risk for addictive forming thoughts and behaviors, can be problematic. Just like any program planning, a medical and/or fitness professional may refer/recommend, there needs to be an appropriate guide to properly integrating exercise into recovery without reaching excess.

PACE stands for Proactive Awareness Controlling Excess. Fit PACE is a guideline/tool to incorporate exercise into recovery safely by being proactive and ahead of excessiveness, being aware of your own addictive behaviors, controlling thoughts/actions, and deterring/avoiding reaching exercise in excess. I have just released the Fit PACE mobile app which details a program for persons in substance abuse recovery to follow for exercise performance. Users not only log days performing exercise for accountability (and to avoid excess), but they also log number of days sober. Graphical images display progress and track this information. Users can connect to other persons on the app, which emulates the group meeting, community support aspect recovery. Users can select their exercise goal and tailor workouts to their level of fitness. It is my hope that both fitness and medical professionals can refer/recommend the Fit PACE app to download and use as a tool during substance abuse recovery. This is in alignment ACSM’s Exercise is Medicine philosophies.

Hashimoto’s Disease: When the immune system turns against you

Megan Johnson McCullough/21 January 2023/ All MFN blog/

Hashimoto’s Disease, also called Hashimoto’s Thyroiditis, occurs when the immune system turns against the body’s own tissues. The immune system directly attacks the thyroid. This then leads to hypothyroidism, which is when the thyroid isn’t making the necessary hormones for proper body functioning. The thyroid plays a leading role in our body, as it is the controller of our metabolism. Without the right hormones, how quickly our body uses calories from what we eat, can be greatly impacted. It is the most common thyroid disorder, affecting 14 million people in the United States.

Symptoms of Hashimoto’s include having an enlarged thyroid. The front of the neck (where the thyroid is located) looks swollen. Symptoms associated with an underactive thyroid, due to the lack of hormone production, include fatigue, weight gain, cold body temperature, hair thinning and loss, depression, irregular menstrual cycles for women, and joint and muscle pain.

The exact cause is not known. There is a strong genetic component. Hormones play a major role, especially since Hashimoto’s is seven times more common in woman than men. Its primary target is middle-aged women. Many women experience thyroid problems after childbirth and about 20% of these women develop Hashimoto’s later on. Certain medications with high levels of iodine can cause this problem. Radiation exposure also can lead to thyroid troubles. In fact, the atomic bombs of Japan lead to this disease in many people. Then, this can be passed on genetically.

Unfortunately, there is no cure for Hashimoto’s. The medical community is not sure what causes autoimmune disorders. Getting medical help is important in order to prevent the progression of the disease. If left untreated women can experience problems with fertility and the risk of high cholesterol increases.

There are some self-care, natural approaches to try to improve or prevent this condition, including your diet. Making sure your diet consists of enough selenium, zinc, vitamin D and iron. Foods to include would be red meat, poultry, beans and dark vegetables. If you do not eat meat, do understand that plant sources are not as absorbable, but taking vitamin C can help with this. Foods you should minimize and eliminate include those that cause inflammation. These include gluten, sugar, artificial sweeteners, soy and dairy. Gut health is critical so making digestion as clean and easy as possible is important. Avoiding toxins can help too, such as plastics, beauty products, air fresheners or candles. Keep your air clean.

Exercise can also be beneficial for Hashimoto’s because it helps lower inflammation and stabilizes the functioning of the immune system. This is because exercise stimulates regulatory T cells which are big inflammation fighters. Also in the process, exercise can balance the pro-inflammatory Th1 system and the anti-inflammatory Th2 system to be less inflammatory. Exercise also helps to release immune cells called IL-6, which lessen inflammation. Just going for walks is a great start but depending on how the person feels, even high-intensity-interval-training (HIIT) can boost workouts and help manage Hashimoto’s. Exercise tolerance is a case-by-case situation and overdoing exercise will only worsen inflammation.

For those I have trained with this condition, we sometimes have to do a trial-and-error approach to ensure the person is doing what their body permits without causing a flare up. It has been my job to scale back intense workouts but still give the client the encouragement and motivation that inspires them to keep exercise as a lifestyle change to support living with Hashimoto’s as best as possible. Many times clients avoid movement thinking their condition prevents them for doing certain types of exercise so why try at all. Movement is medicine so if it’s just walking, it is doing the body good versus being sedentary and lethargic.

Thyroid disease is becoming a major problem. Nearly 20 million Americans have some form of the disease. Diagnosis isn’t always clear at first, but we know when we don’t feel right. Don’t give the thyroid any more power than it already has. Hormones might be tyrant rulers, but we can control our actions and attitude towards feeling our best. Autoimmune diseases are unpredictable. The thyroid greatly influences our metabolism, so our weight is readily affected by its functioning. Although our genetic makeup can leave us powerless, we do have the ability to control our response, adherence to medical help and ability to keep a positive outlook despite medical situations.

Aging and Exercise

Megan Johnson McCullough/12 August 2022/ All MFN blog/

Time dictates so many aspects of our lives. When beginning this article, I thought to myself how much time controls my day from the seconds, minutes, and hours. And of course in relation to this piece of writing, it is the measure of our age. The aging process is unique to each of us. But ultimately, it does impact our life decisions, and that includes our exercise choices. So let’s take a look at the relationship between aging and exercise.

Naturally, activity level changes when we get older. As one of my long time clients put it, “Man, I don’t just roll out of bed anymore ready to go”. This isn’t to say that one is less motivated, rather, the energy expenditure levels are different. This is mainly due to the fact that, “A major fraction of total daily energy arises from resting metabolism, and it is thus important to note that resting metabolism decreases with aging, by about 10% from early adulthood to the age of retirement, and a further 10% subsequently.” (1) Adding to this, “One reason is the loss metabolically active muscle mass and parallel increase in metabolically inert depot fat. In later old age, there may also be some overall reduction in cellular metabolism.” (1) When muscle mass decreases, this can cause body fat to increase. Keeping the excess pounds off can get harder. As such, “Your body fat can increase by up to 30 percent, which leads to a loss of lean muscle tissue and can affect your sense of balance. This can make it difficult for you to perform exercise activities you once enjoyed.” (2)

We need to continue a strength training program in order to not let our bodies replace muscle with fat at the rate it would like to. Not to use a scare tactic but here you go: “Strength peaks around 25 year of age, plateaus through 35 or 40 years of age, and then shows an accelerating decline, with 25% loss of peak force by age of 65 years.” (1)

Exercise becomes so extremely important as we grow older. We tell ourselves that we used to be able to eat whatever we wanted and still look fabulous, but now the odds aren’t necessarily the same anymore. We have to take care of our bodies, and we can help prevent certain diseases with exercise. For example, “Your bone mass begins to decline once you enter your thirties, putting you at risk for conditions such as osteoporosis. If you are concerned about developing this condition, perform more weight-bearing exercises, such as running and tennis. Regular cardio activity will also help you control high blood pressure and high cholesterol, as well as ward off type 2 diabetes and some kinds of cancer.” (2)

As I always say, there is no can’t. That word is not allowed in my studio. There are modifications for so many exercises, and I will be by your side as we run, walk, or crawl to get it done. If we don’t use it, we lose is, right? Not every day is a peak performance day, but we do we can. As long as we are active, we are being productive to our bodies. Running a marathon might not be in the future, but what about making to your training session twice a week and keeping that commitment to your body? Goals should be realistic. Remember the glory days fondly, but know that you are keeping your mind and body in better condition and sticking around longer for your family and friends by maintaining an exercise program. Fitness is a way of life and the destination involves progress not perfection so just keep going one rep a time, one day at a time, and with every age of your life.

Autism Spectrum Disorder – Where Fitness Professionals Land on the Spectrum

Megan Johnson McCullough/1 July 2022/ All MFN blog/

According to the CDC (2022), about 1 in 44 children has been identified with autism spectrum disorder (ASD). Autism Spectrum Disorder (ASD) is a neurological disorder marked by deficits in social communication as well as repetitive behaviors and restricted interests (Hodges et al., 2020. This information tells us, that it is likely in the near future or even now as a fitness professional, we may experience having a client with ASD. Being a neurological disorder, there can be faulty lines between mind and body communication that influence body movements and mechanics. Therefore, as a fitness professional, working with an ASD client would require individualized programming tailored to specific needs, but there are common sensory and motor skill deficiencies we as fitness professionals can certainly assist with.

The Diagnostic and Statistical Manuel of Mental Health Disorders (DSM-5) has now coined the term “spectrum” to include both lower and higher functioning forms of autism.

The ”spectrum” consists of the following:

autistic disorder
Asperger’s disorder
childhood disintegrative disorder
pervasive developmental disorder not otherwise specified (PDD-NOS)

Furthermore, the DSM-5 requires the following for diagnosis:

Individuals must meet all the social communication/interaction criteria:

problems reciprocating social or emotional interaction
severe problems maintaining relationships
nonverbal communication problems

Must also meet 2 of the 4 restricted and repetitive behaviors criteria that do cause functional impairment:

stereotyped or repetitive speech
motor movements or use of objects
excessive adherence to routines
ritualized behavior, or excessive resistance to change
highly restricted interests, abnormal in intensity or focus
hyper or hypo reactivity to sensory input or unusual interest in sensory aspects of environment

There are a number of risk factors for ASD including sex because ASD is 4 times more common in boys than girls. Other risk factors include family history, age of parents when born, and being born early (CDC, 2022). The fitness professional will of course meet the ASD after diagnosis but being aware of certain behaviors and traits is an important component to help better understand and relate to the client’s needs and abilities. The fitness professional can become part of the ASD client’s comprehensive treatment program. There is a need for our help, especially since obesity rates are higher among persons with ASD. Although some of this can be related to diet, lack of physical activity is a key contributor to this phenomenon. We know that P.E. at school alone is not enough time spent moving, and because persons with ASD might need special sensory and motor accommodations, this can be a deterrent for participation. Without the advocacy of parents, activity may not be prioritized.

Common among persons with ASD, there exist vestibular, proprioception, interoception, low muscle tone, postural instability, and compromised endurance and balance deficiencies (Autism Speaks, 2022). Adding to these, persons with ASD have been found to have differences compared to those without ASD with gait (stride width, velocity, and stride length) (Autism Speaks, 2022). As fitness professionals, we have the knowledge and experience to program design for these fitness and skill related components, so having a specialization to reach this population makes us both more credible and more marketable. Special populations need special people like us to add exercise as medicine and improve quality of life, despite the challenges, stereotypes, and stigmatisms that exist when it comes to persons on the “spectrum”.

Tattoos & Heat Loss During Exercise

Megan Johnson McCullough/11 April 2022/ All MFN blog/

Tattoos are personal permanent images on our body that carry meaning and commemoration. At least 14% of U.S. adults have at least one tattoo and the popularity of getting inked is on the rise. Nearly 36% of millennials have a tattoo and it seems to be a reoccurring trend. The athletic community also has a high incidence of players with tattoos.

As much color as these skin decorations bring to the body, they may actually affect cause thermoregulatory problems. This is particularly true for people with sleeves, because the arms have a lot of sweat glands. Compared to a person with no tattoos, skin with ink on it sweats about 50% less. The type of sweat released on a tattooed area contains more concentrated amounts of sodium. Dyed skin changes the saltiness of our sweat. When the dye is injected into the skin, its home is same layer where our sweat glands live. Sweat glands excrete liquid onto the surface of the skin, but before it dries or we whip it away, our skin usually reabsorbs quite a bit of the lost sodium and electrolytes. Tattoos block this reabsorption. The age of tattoo does not influence this sweat alteration. New or old, about 50% of sweat is being produced. It is possible that the sweat glands after being inflamed from the 3,000 or more needles puncturing the skin, are now physiologically different.

This is not a serious condition to sweat about. The body is still able to cool itself down despite tattoos covering perspiration avenues. A person who is covered in tattoos, exercising or working in high heat, or are sensitive to heat, might be at risk. When we exercise we do want to be able to cool down to keep our stamina and performance up. Research has not been adequately performed to determine if the areas of the skin lacking tattoos make up for the sweat not readily perspired by the covered tattoo areas. Don’t worry that if you sweat less you will lose less weight. We all perspire different amounts and quantity of sweat does not equate to quantity of weight loss. As soon as the body become rehydrated, that water loss is replenished. Excessive sweating for weight loss with saunas or body wraps are popular methods among wrestlers and boxers. Maybe they should skip out on marking their bodies.

Sweat is the body’s air conditioning system. Tattoos might alter the desired temperature. 50% of NBA players have multiple tattoos and there hasn’t been a report yet of tattoo related injuries. Your skin will still get shiny with perspiration, but maybe not the same amount or with added salt. Be sure to hydrate, be sure to exercise, and be sure to get a tattoo you want to keep.
