Why Zinc Is So Important

Here is an article which I wrote a few years ago and which still applies to general health:

Zinc is a vital mineral which is found in every tissue in the body due to its involvement in cell division. In the world of fitness and bodybuilding, zinc has a number of roles, including maintenance of normal hormonal levels, proper endocrine function, body composition, energy levels, optimal physical performance and protein synthesis. Thus it is crucial to maintain normal levels of zinc in the body when training or prepping for a competition.

Zinc is highly concentrated in meat, dairy and some seafood. This is why vegetarians most commonly suffer from zinc deficiency. So how can you tell if you suffer from a zinc deficiency? Common symptoms include an altered sense of taste which leads to cravings for sweets and salty foods. Other symptoms of zinc deficiency include low energy, infertility, low libido, memory problems, poor immunity and diarrhea.

A relatively easy way to test yourself to see if you are deficient in zinc is to do a taste test. Take 1 to 2 teaspoons of zinc sulfate (you can get this at health food stores) and add to a cup of water. If it tastes just like water, you are very zinc deficient. If you experience a slightly metallic taste, you are moderately zinc deficient. If it is strongly metallic and unpleasant, you most likely have normal zinc levels. Please bear in mind that this test is never as accurate as a blood test, but at least it will give you an idea of what your levels are.

For those of you who want to know the specific health benefits of zinc, here is a list of benefits.

Enhances Strength and Athletic Performance:

Zinc plays a major role in anabolic hormone production which makes it a key player in optimizing athletic performance and strength. When zinc levels in the body are normal, more growth hormone and insulin-like growth factor-1 is released, which result in enhanced muscle growth and performance. Researchers have also noted that zinc enhances the conversion rate of androstenedione to testosterone, which improve strength gains during the recovery phase.

Enhances Reproductive Health and Fertility in Both Men and Women:

The cells of the male prostate require an extremely high concentration of zinc for proper function. To give you an idea of how much zinc is necessary in the prostate, male prostate tissue requires ten times more zinc than other cells in the body for normal function. There is a correlation between low zinc levels in men and increased risk of developing prostate cancer and infertility. There is also evidence to support the link between low zinc levels and low libido. Another implication with low zinc levels is its importance in maintaining optimal testosterone levels. Men with low zinc also tend to have low testosterone, which puts them at greater risk of andropausal symptoms.

In women, proper levels of zinc are essential for egg maturation and ovulation. Zinc also optimizes utilization of estrogen and progesterone and regulates their levels. During pregnancy, zinc plays a vital role in ensuring proper cell division in the growing fetus and helps to prevent premature delivery.

Essential For Taste, Smell and Appetite:

Zinc activates areas in the brain that process information from taste buds in the mouth and olfactory cells in the nasal passages. In addition, levels of zinc in the plasma influence taste preference and appetite. Many programs which treat anorexics use zinc to revive taste and appetite.

Makes Skin, Hair and Nails Healthy:

Zinc accelerates skin cell renewal which is why it is commonly used in diaper rash creams, acne treatments and creams which are used to treat dermatitis. It has strong anti-inflammatory properties and has a soothing effect on rashes, burns and blisters. Some shampoos contain zinc to help prevent dandruff. What you may not know is that zinc is important for healthy hair and that low zinc levels can cause hair loss, dull and thin hair, and loss of pigmentation.

Essential For Vision:

Zinc is found in high concentrations in the retina, but this level declines with advancing age, precipitating age-related macular degeneration which is characterized by a partial or complete loss of vision. Zinc also has a protective effect against the development of cataracts and night blindness.

Supports Cardiovascular Health:

Zinc is vital to normal cardiovascular function. When levels of zinc are low, the endothelial layer in blood vessels becomes inflamed and accumulates cholesterol deposits, both of which increase one’s risk of heart disease. Low levels of zinc can amplify the negative cardiovascular effects of diets which are high in fat and cholesterol, whereas adequate levels of zinc will inhibit the progression of heart disease.

Increases Insulin Sensitivity:

The presence of zinc is essential for normal function of most hormones, including insulin. Zinc binds to insulin and aids in storage in the pancreas as well as release of insulin in the presence of serum glucose. In addition, zinc is found in the enzymes which enable insulin to bind to cells so that glucose can be utilized for fuel, a process better known as insulin sensitivity. Why is this important? If zinc levels are low, enzyme levels drop, insulin sercretion drops and glucose remains in the bloodstream, a process which can lead to diabetes if it is chronic.

Improves Mood:

Dopamine, a chemical in the brain which boosts mood and energy, is partially regulated by zinc, so zinc once again plays an important role in the body. There is also evidence to support the theory that the presence of zinc boosts serotonin levels in the brain.

Supports Immune Function:

Zinc supports T cell function and is thus strongly tied with combating inflammation. T cells are responsible for mounting an immune response to invaders such as bacteria or viruses.

Has Potent Antioxidant Effect:

Zinc can remove toxins from the body and prevent accumulation of harmful compounds in tissues. This mechanism has a protective effect against the development of cancers, especially in the prostate, ovaries, pancreas, breast and colon. In addition, zinc prevents the buildup of heavy metals in the brain such as aluminum, which has been closely linked with Alzheimer’s disease.

If you suspect that you are deficient in zinc, you can supplement daily with 20 to 30 milligrams.

Why Fifty Is Great

So far, I have really enjoyed being fifty years old. It isn’t nearly as alarming or horrific as I had made it out to be. In keeping with the slogan which was on my most recent birthday cake, I truly feel like “50 IS THE NEW 20” and am thrilled that my physical appearance has also kept up with my spirit, mind, and intentions.

After spending a half-century on the planet, I no longer have the patience to deal with people who can’t honor their word. My tolerance has completely dissolved, and I think nothing of tossing flaky people to the curb. I guess the old adage, “with age comes wisdom” has a lot of truth to it. My gut instinct has proven consistently to be a foolproof guardian, so I no longer try to fight it. I trust it completely.

I cannot and will not wait for things to happen. I need to generate my own momentum and know that I can only truly depend on myself. Challenges will continue to hit me, but I feel stronger than ever about my ability to handle anything that comes my way. I also know that situations will always find their own resolution eventually. I also trust the process by which situations must unfold, and I also put tremendous faith in the universe. I maintain a connection with the universe by meditating daily and by keeping energy flowing through me.

Neurological Disorders and My Loved Ones

drstaceynaito Leave a comment

It seems like neurological disorders abound with my loved ones. My aunty Alice developed cerebral palsy after contracting an infection during infancy. My uncle Katsutoshi fell into a persistent vegetative state after an unlocked construction crane fell on his head and back. My uncle Harumi experienced several strokes, as did my aunty Carol and my dad. My mother sustained a subarachnoid hemorrhage (aneurysm rupture) along with senile dementia. My dear friend and meditation teacher Rob was diagnosed with an aggressive brain tumor, a glioblastoma multiforme, which took his life within five months.

My favorite aunt Jean was diagnosed with the sporadic form of amyotropic lateral sclerosis (ALS) in early 2016, adding yet another neurological illness to an already large list. The disease was so aggressive that by October, she was unable to speak, so my calls consisted of me making awkward small talk while she grunted in response.

Considering the fact that I had a keen interest in neuroscience since childhood and believed that I would become a neurologist even in my final year of medical school, I find it ironic that so many people who have been near and dear to me have fallen victim to so many neurological maladies, ranging from cerebrovascular events, to neuromuscular disorders, to traumatic brain injury, to neoplasm. Despite this, my fascination for the neurosensory system has not abated. I just hope my favorite people don’t keep getting struck by ailments which afflict this system.

Low Vitamin D Levels Linked to Macular Degeneration Risk

Vitamin D has gotten more attention in recent years, as a result of extensive research which has explored the impact of a deficiency in this important substance. A meta-analysis on vitamin D deficiency which was published earlier this year in Maturitas revealed a possible correlation between low levels of 25-hydroxyvitamin D in the body and increased risk for development of age-related macular degeneration (AMD). Furthermore, scientists surmise that if a vitamin D deficiency is corrected well before any signs of AMD are present, the disease’s prognosis is much improved.

The meta-analysis revealed that individuals with macular degeneration had vitamin D levels which were an average of 15% lower than levels in individuals without the disease. Another analysis revealed that subjects with highest circulating levels of vitamin had 50-80% lower odds of developing AMD compared with those who had the lowest circulating vitamin D levels.

However, despite all of these findings, it is not yet clear whether vitamin D supplementation would have a protective effect against AMD. In addition, the lower vitamin D levels found in some subjects may have resulted from the pathophysiology of AMD itself.

Rather than take a chance, I would prefer to promote vitamin D supplementation under the assumption that low vitamin D levels are a causative factor in the development of AMD. I also lean strongly towards a brief amount of exposure to sunlight daily in order to boost vitamin D levels naturally. In order for such exposure to be effective, sunscreen cannot be used around the clock. My recommendation is to sit in the sun for 3 minutes daily.

Botox As An Antidepressant?

The concept that Botox treatments can effectively treat depression has been around for a while, but a study surrounding this idea has recently been published in the Journal of the American Academy of Dermatology. Dr. Jason Reichenberg was able to determine that depression scores dropped over 40% in patients who had Botox treatments, versus 15% in patients who received a placebo. This was the case even in patients who were dissatisfied with the cosmetic result of Botox treatments.

The results point to Botox as an effective means of treating depression, especially in patients who are resistant to other treatments for depression. By relaxing the frontalis muscle and glabellar complex in the forehead, Botox makes it difficult for an individual to frown, which in turn appears to have a positive effect on mood and well-being. If you can’t frown, then you can’t fully experience the distress which a frown would ordinarily express, causing a modification of mood.

Botox is also used for correction of lines and wrinkles around the eyes, migraine headaches, temporomandibular joint disorder (TMJ), and excessive sweating.

Bound And Determined

People frequently ask me what my biggest life goals are.  As a chronic overachiever, I entertain many different interests and am pretty fearless about diving into new ventures and determining whether I have talents which fee them. 

My BIGGEST passions lie in the fields of medicine and fitness.  From the time I obtained my bachelor’s degree in Exercise Science, I have been completely committed to fitness and to leading by example.  My medical degree is another feather in my cap which increases my knowledge and my influence, but I always strive to combine all my talents and interests together as much as I can in order to lend a number of perspectives on health, wellness, anti-aging and fitness.

My ultimate goals in medicine and fitness are to:

1) Have my own TV show.  A few years ago, I began stating that I wanted to become the female version of Dr. Oz.  I said this at first in jest, then became more intrigued by the idea until it became one of my ultimate goals.  I reasoned that if Dr. Oz can command the attention of women around the globe (his viewer demographic appears to be mostly women between their early 20’s and late 60’s), why couldn’t an attractive 50-year old female physician, fitness professional, IFBB Pro, writer, and model who is also highly experienced in aesthetic medicine, nutrition, fitness and anti-aging achieve something similar? That shift in thinking was all I needed to spark a tremendous goal which I am constantly trying to manifest. And come hell or high water, I will reach this goal.

2) Establish a foothold in the fitness industry as an icon for the older crowd.   This is also HUGE for me, whether it manifests via workout content, products which are sold with my name or endorsement on them, or even a specific show on television or the internet. Instead of allowing my chronological age to deter me from going after I want, I use it to empower my goal set and am proud of forging new ground in territories which other people may be afraid of stepping into. I also refuse to allow others to discourage me because they have narrow minded ideas about what someone my age should be doing. I will not be the stereotypical fuddy-duddy who grumbles about my age and who lets it block me from my goals.

3) Launch my own specialty skin care line.  I have wanted to do this ever since I held the position of Director of Cosmetic Research at a Los Angeles area hospital.  Since I am of mixed ethnicity I would love to tailor a line of skincare products and cosmetics towards individuals of multiple ethnicities who have unique concerns. I honestly believe that there are too many harsh and reactive chemicals which are used in skincare products and cosmetics, and also understand first-hand that people of color have different needs and issues.

4) Design women’s fitness apparel and swimsuits with a distinctive edge.  I have yet to see clothing and swimsuit designs which incorporate the design elements I have always wanted to see and which are edgy and appealing.  The only thing that has been my real stopping point here is that I cannot stand sewing! When I was 17, I designed an entire spring line of active apparel for a company, and was thrilled to see my vision made and sold. Decades later, I’d love the opportunity to delve into that world once more.

What do I want to be when I grow up?  Lots of things!  I will keep my nose to the grindstone to make these goals and dreams manifest.

Cheat Meals (Repost)

drstaceynaito Leave a comment

The following article was posted a couple of years ago here on my blog site…

If you ask a competitor about favorite cheat meals, you had better expect the person’s eyes to glaze over as he or she lovingly describes his or her most beloved foods. You may wonder if cheat meals are only incorporated into the lives of fitness people, but they actually serve a purpose for anyone who is committed to healthy eating. Perhaps you have just embarked on a healthy food regimen and are struggling with it. When you incorporate one or two cheat meals into your plan each week you will boost your metabolism and foster a more balanced relationship with food.

Let’s face it. We are only human, and we carry our emotional relationship with food with us throughout our lives. If we were to practice a rigid adherence to a healthy meal plan without any fun meals, we would feel guilty if we were to ever indulge in a bad food in a moment of weakness. There is a diagnosable condition known as orthorexia in which people develop a mindset which demonizes all but the cleanest foods, and which sets up a cycle of shame and remorse every time forbidden foods are consumed.

Rather than punish yourself for eating anything which falls outside your concept of “clean” foods, you have a far better chance of harboring a healthy approach to food if you allow yourself to enjoy the occasional treat. If you know that you are allowed to eat a fun meal (I prefer this terminology over “cheat” meal), you can rest in the comfort that it is acceptable, and avoid the psychological spiral which can create unnecessary anxiety. This also works nicely if you tend to go to events on the weekends and don’t want to be the party-pooper who can’t ever eat anything that is being served.

When you eat a more calorie controlled meal plan during the rest of the week, a fun meal will speed up your metabolism and satisfy cravings that have been accumulating during the week. I believe it is important to eat something you truly crave instead of doing a small cheat. For example, if you are craving pizza, go ahead and have a couple of slices of pizza, and quit pretending that you would be perfectly happy with a rice cake topped with some tomato sauce as a substitution! Just make sure to eat an acceptable amount of food and don’t gorge yourself. This means exercising some self-control so that two pieces of pizza don’t turn into an entire large pepperoni pizza which you annihilate in one sitting.

I am often asked by weight management patients if a cheat day or a cheat weekend is acceptable. My response is no, for the simple reason that this creates a slippery slope which causes many individuals to lose self-control and spiral into the guilt-ridden “I messed up so why stop now?” mentality. If it is too difficult to do one fun meal per week, incorporate two smaller fun meals spaced by at least one day so that your body can recover.

My Oldest Patient

drstaceynaito 1 Comment

Shortly after I completed my residency training in family medicine in 2004, I worked briefly for a company which offered mobile physician home visits. Though I soon realized that driving to patients wasn’t my thing, I definitely met some very interesting people during that time.

My favorite and most memorable patient from my mobile medicine days was an elderly woman, aged 105. During my hospital days, I had seen and treated a number of centenarians, but this woman was the oldest. I was called upon to visit this woman’s home (I’ll call her Mary) to perform a blood pressure check and manage her hypertension. She lived in a charming duplex which was erected circa 1905. I knocked on the door and when the door opened, a friendly middle-aged man greeted me and introduced me as Mary’s caregiver (let’s name him Tim).

The interior of the duplex was a time capsule. I honestly felt like I had stepped into the 1920’s, because everything in the place was from that era: lamps, paintings, coffee cups, pens, furniture, curtains, pillows, etc. As my eyes scanned the room, I saw Mary sitting in a large chair with a walker in front of her. Mary’s face certainly was old and her body was frail, but she possessed fire in her eyes and a sassy attitude to match. I thought of how this woman, born in 1899, was witness to three different centuries, as a result of the year she was born as well as the longevity which extended her time on planet Earth far beyond that of the average person.

Mary smiled at me and motioned for me to come over.
MARY: “Well you’re a pretty young lady…what’s your name?”
ME: “Hello Mary, I’m Dr. Naito.”
MARY: “DOCTOR??? DOCTOR??? Tim, what have you tricked me into? Why do we have a doctor here?” Mary’s brow was furrowed.
TIM: “Well Mary, since you refused to take your blood pressure medicine, and since your blood pressure reading was very high today, I had to call the mobile doctor service to come see you. Now be nice to the doctor, will you please?”

20161206_161832

At this point I asked Mary if I could take her blood pressure again, and she consented. I took her blood pressure reading: 175/95. I began to ask Mary questions: was she in pain anywhere, did she have a headache, was she dizzy, was she nauseous, was her heart racing, was her vision blurry? I took her pulse: 78 and steady. Mary had no complaints. I then conducted a physical exam on her, which was completely normal. I then asked Mary if she would please take her blood pressure medication immediately, to which she also consented. Once Mary took the medication, I informed her that we would wait about 30 minutes to assess her response to it. She responded by saying, “Well I like you, young doctor! We’re going to have a nice chat!”

The next 30 minutes were incredibly fascinating and funny as Mary settled into a stream of vignettes about her life, focusing mostly on her days as a true flapper, wild and carefree, wearing short dresses, “necking” with handsome young men, hanging out in jazz clubs, and being a general troublemaker. One of those young men managed to steal her heart, and they married in 1922. She spoke about how she became an actress quite by accident when her husband, who was a Hollywood film producer, began to cast her in his films. Mary and her husband were more interested in traveling the world and investing their money than buying an expensive home, so they lived in their modest duplex from 1922 until his death almost 60 years later, and Mary refused to move into an assisted living facility when she became an invalid. It was the same duplex I was visiting that day.

After thirty minutes of hearing the most engaging stories about Mary’s life, I didn’t want to interrupt her. But I was working, after all, so I told her I needed to re-take her blood pressure. This time it was 138/72 and Mary was still completely asymptomatic. I told Mary that it was time for me to go and began gathering my supplies.
MARY: “Oh no you don’t! You’re going to drink a martini with me. It’s my nightly ritual. Been doing it since I was 20 years old.”
ME: “Every night since 20?”
MARY: “Yes indeed. It’s kept me sane all these years, and I enjoy it.”
ME: “But I need to drive over the hill, and it’s rush hour.”
MARY: “Oh please! Now stop complaining and just sit. Tim, make my usual times two.”

After several minutes Tim emerged from the kitchen with two double gin martinis. I don’t like gin, but I wasn’t about to complain or refuse to drink the martini. Mary and I (actually, she talked and I listened) continued to talk for another 30 minutes while sipping on our cocktails. The martini was STRONG but well made, so I continued sipping. Mary polished off her entire martini like the martini drinking expert she was, and motioned to me when she took her last sip. “Well, dear? You’ve got some left in there.” I had to finish the last couple of sips of my martini while Mary watched me, making sure I did so. Once I did, she smiled warmly. “That’s my girl!”, she beamed.

I gathered my belongings and said goodbye to her, and when she motioned for a hug, I walked over to her and wrapped my arms around her. She hugged me and patted my back with her hand.

I never saw her after that.

I Can’t Eat That! – Balancing Healthy Eating and Normal Life

Fast_Food hottie

There are countless challenges and roadblocks which can derail us from our efforts to follow a healthy meal plan, especially when we are faced with the indulgent foods that emerge during the holidays. Whether you are a seasoned competitor who is accustomed to following a strict meal plan, someone who wants to adopt healthier eating habits, or battling excess body weight, it can be very difficult to pass up regular restaurant meals, fast foods, and holiday treats. However, it IS possible to stay on track even in the face of such temptations.

The first and most important thing is to remember your GOAL, whether it is improved health, weight loss, or getting into contest shape for an upcoming event. Your goal should serve as a tangible mark which you are aiming for. I always tell my patients and weight management clients to post images of people who possess the type of physique they covet in a prominent place (such as a refrigerator) so that they can be reminded of their specific goal.

Here are other effective strategies to help you follow a healthy meal plan:

Keep forbidden foods out of the kitchen so that the temptation to eat something unhealthy is removed. This means that you need to avoid purchasing chips, crackers, cookies, ice cream, packaged pasta dinners and whatever other unhealthy foods you tend to gravitate towards. If unhealthy foods are not in your kitchen cupboards, you won’t be tempted to grab them and indulge.

Prep your meals at home beforehand. Meal prep can be tedious but it is well worth it when you consider the control you will have over what goes into your body. You can control ingredients, cooking method and portion sizes and maximize your chances of maintaining healthy eating habits. Once you have prepared your food, you can store single serving sizes in individual storage containers which are easy to pack when you need them.

Invest in a great food cooler bag. Trust me, you NEED one of these!

Make sure your meal plan is balanced. The best meal plans have lean protein, healthy fats and slow digesting carbohydrates. Do not fall into the trap of thinking that all fat is bad! You need certain healthy fats to maintain normal cellular function.

Avoid fast food restaurants. Fast food restaurants (and most restaurants for that matter) feature extremely unhealthy options which can completely destroy your efforts at reaching your health and fitness goals. You will also save a ton of money by avoiding the calorie and saturated fat laden options found at such establishments.

Don’t cave in to peer pressure. I don’t know what it is about friends and family, but it seems like they get some twisted thrill out of convincing others to eat forbidden foods. If you find yourself in such a situation, you need to ask yourself if it is worth unraveling your healthy eating habits in order to appease a relative or buddy. I have heard, “Awww, come on, a couple of bites won’t hurt ya!” from people who usually mean well but who are unaware of the psychological torture they might be putting me through. I honestly don’t want to be pressured into consuming something that will make me feel guilty or will not digest well . It isn’t worth it!
