In this current day we are spending far too much of our lives being sedentary. Sedentary behaviour is described as a distinct class of behaviours (e.g., sitting, watching TV, driving) characterised by little physical movement and low energy expenditure. But is sitting REALLY the new smoking? Around 15 studies looking at the relationship between sitting and all-cause mortality indicate people who had the highest levels of sitting (around 8-9 hours/day) had ~20% increased risk of premature death compared to those people who sat the least. For smoking, however, smokers had around a 200% increased risk of premature mortality compared to non-smokers, and this risk increased to 400% for those who had the highest rate of smoking! As you can plainly see, the difference between smoking rate and mortality risk is MUCH higher than those who are sedentary. This is not to say that sedentary behaviour is not concerning to health. Risks are said to include:
- Decreased Metabolism
- Decreased bone mineral content
- Decreased vascular health
- Increased cardiovascular disease
- Increased plasma triglyceride levels
- Decreased levels of HDL (good) cholesterol
- Decreased insulin sensitivity
- Increased obesity
- Increased cancer risks
- Increased psychosocial problems
Being seated for long periods of time also increases pressure on your lumbar spinal discs which can increase the chance of disc bulges and herniations. This position also tightens up your hip flexor muscles and contribute to an anterior pelvic tilt that will lead to lower back pain. So try and break up long periods of sitting, and get up from your seat more often throughout the day. Stand up whilst taking phone calls, do calf raises whilst seated, take exercise breaks every hour where you get up and walk around. Think of creative ways to get up and about. Lots of little behavioural changes can contribute greatly to improving your health and reducing morbidity and mortality.
Orthorexia nervosa is an unhealthy obsession with healthy eating. It is a “health food eating disorder”. Yes. You read it correctly. When anyone has an exaggerated focus on something – even something healthy, it can become problematic.
Today more than ever we have cult-like behaviour from people following multitudes of fad diets. As a result, they follow strict regimes of eating, not allowing this or that to the point of the ridiculous. Furthermore, there are extremists who are devoted to cleanses, detoxes, Atkins, paleo, veganism, gluten- free, juicing…….the list goes on and on.
However, don’t mistake my blog….I am NOT telling you that focusing on healthy eating is wrong or that you should throw caution to the wind and eat whatever you like. I am advising you to make educated decisions towards healthier eating behaviour where it doesn’t negatively impact your life. When your healthy eating completely consumes you to the point of obsession, (specifically, where you cannot function without total commitment and are filled with guilt at the very thought of other options), then it is a cause of concern. Clearly it is a problem if it causes a person distress,
Additionally, an unhealthy obsession with food can affect friendships, relationships, and even your own sanity. In particular, it can cause social isolation and mental health problems. It is important to understand that stress causes many physiological complications too. Consequently, stressing over food can manifest itself negatively by causing health problems in the very body you are trying to keep healthy! Ironic isn’t it?
Focusing on health doesn’t need to be a chore. We shouldn’t constantly try and eat like bodybuilders preparing for competition! I have been around these athletes for many years and trust me, they aren’t happy to be on such restricted eating regimes and don’t eat that way once their comp is over. Make healthier food options whenever possible but don’t let your desire for health stop you from living! Find a balance and don’t make food the primary focus of your life.
It is common for people to drop grocery products into their trolleys out of habit, without arming themselves with the information required to determine if their choice was the best one for their body, or just for their taste buds! So many of us grocery shop blindly and wonder why our health is compromised. Supermarkets are clever little manipulators. They structure their products to influence your “choices”. Manufacturers pay for shelf positioning, so those who pay the most get their products placed in the most convenient line of sight for consumers … eye level. The healthier more nourishing and nutritious choices are usually harder to find, and if you aren’t specifically looking for them, they would be easy to miss. And don’t get me started on how they strategically place chocolates and chips at the checkouts to tempt you and your children whilst you are waiting in line! So how do you make healthier shopping choices? Here are some basics to guide you.
- Get into the habit of comparing items and identify healthier options (see below).
- Read & understand the nutritional panel. The lowest calories are not always the healthiest options. Check out this video https://www.youtube.com/watch?v=KMGUmcveQeg
- Examine the ingredients list. The order of ingredient represents its amount in the product, i.e. if sugar is listed as the first ingredient, then sugar is the main ingredient in the product. This would be a good reason for returning that item back to the shelf! Look for products that contain healthier ingredients and stay away from those E numbers as much as possible. (There are great apps for your phones that help you identify those confusing E numbers so this is something I recommend).
- Allow more time on your first few shops to study the products.
- Avoid grocery shopping when you are hungry. You will tend to make less healthier choices.
- Compare 100g not per serve. Comparing one product with a 50g serving to another with a 35g serve can be easily misleading.
- Total energy is important but low HI (Human Intervention) is the most significant factor (meaning the product will be more nutrient rich). Wean yourself off all the processed gunk that is clogging up your body and preventing it from performing at its best. Low energy ≠ healthiest as stated earlier. Use the ingredients list to help you determine this. It is more informative than the nutritional panel.
- Don’t focus too much on protein or total carbohydrates at first. Gradually work these in later when you are more comfortable with everything else.
- If plant origin – then ↑ fibre. It is recommended that we have 30-40g per day but this is thought by some dietitians as being too low. Our ancestors were having up to ten times that amount!
- ↓ sugar (but also be mindful of artificial sweeteners which can have their own negative effects on health).
- ↓ salt. Sodium is necessary. It is an electrolyte and essential for electrical activity through the body (such as muscle contraction, including the heart). But so many processed foods are swimming in the stuff. The American Heart Association recommends that adults stay under 1,500mg per day and never take in more than 2,300mg per day. To put this into perspective, 1/4 teaspoon of sea salt contains 562mg sodium.
I would like to finish by asking you to ponder the following statement: “The absence of conclusive data demonstrating harmful side effects does NOT mean the product is safe!” As we are still learning about the long term effects of certain food products in our daily diet, proceed with caution and attempt to eat as close to nature as possible. No diet is best for every single person on the planet. Whether you are a paleo, vegetarian, vegan…eat according to what suits YOUR body best and make adjustments accordingly. Tribes throughout history have flourished on very different diets so to think one is the absolute best for all is just ludicrous. The one constant similarity is that they have all eaten from nature. I hope you take the time deserved to involve yourself in healthier grocery shopping. Your body needs you to pay attention. Remember that the absence of disease is not health, so don’t wait for symptoms of illness before you change your behaviour. Prevention is better than cure and we are supposed to be adults who act responsibly … but are we? Your children are learning from you. Do not “bless” them with a shorter lifespan riddled with disease, because that is the current reality due to increasing sedentary lifestyle and the landscape of food that they have grown up eating. Only YOU can change this! Take back control and reap the benefits.
When I look around my gym I am consistently surrounded by people who are performing advanced exercises BADLY! Most assume that they are more competent than they actually are, and instead of gradually progressing their exercises they just jump past the fundamentals and leave themselves open to increased injury risks. Just as most things, exercise technique is mastered in stages. We need to learn the basics to build the motor skills that form our foundation. If we skip these essential stages then our bodies are not as adequately prepared and cannot support us as well. It is like building a house directly on sand! Many exercisers are too impatient and want everything “yesterday” and don’t put in the hard work that is necessary. The result is overloading certain body structures and causing more forces than they are capable of handling. The body works best when it shares the load, and core muscles/stabilisers/neutralisers all need to work together with global muscles. Imbalances will cause postural shifts away from neutral, and this is the best recipe for injury and pain. I’m confident that you have all seen this – a person lifting a weight they should never be attempting right now, or someone performing an exercise with horrendous form. Exercise technique is a skill………and only perfect practice makes perfect execution.
What is sadder is that I also see personal trainers giving the wrong exercises to clients……when they need to be assessing their client’s current capabilities and not just their end goals. The phrase “just because you CAN, doesn’t mean you SHOULD” always comes to mind when I observe such behaviour.
Correct exercise progression is an important part of skill development. Please be aware that incorrect exercise technique doesn’t always cause immediate problems, but also longer term chronic conditions. Don’t just train for your short term desires. Understand they may cause you a lifetime of misery down the track.
Find a professional trainer who really knows what they are doing and base your exercises and progression in a manner that will show you not only the best gains aesthetically…….but also physiologically. If you can’t perform an exercise properly….then you shouldn’t be performing it at all. Be aware of your limitations and only progress when you have mastered the previous stage. Don’t let your ego dictate your exercise and weight choices! Take a step back and build up to it gradually. Yes….your body needs to be challenged in order for it to change but this is not what I am talking about. Challenge yourself within your capabilities and not above them. You will experience a longer and more capable training life this way.
One of the most common questions I have been asked over the past 30 years is “Gina….what are the best abdominal exercises for getting a six pack?” For any of you other fitness professionals out there you will understand my reluctance to answer such a complicated question with a few word answer. It is so frustrating for me to comprehend that so many people would think the human body is such a simple machine, where-as in reality it is quite the opposite. There are so many considerations to make before giving an adequate answer to such a complex query, and yet I hear so many trainers give inadequate advice as if there is only one way. That is just pure ignorance and something that I struggle with ignoring if I experience it.
OK, so when I put my exercise physiologist hat on, my first consideration is “what are your current limitations/injuries/abilities?” An exercise that is quite safe for one person can be absolutely destructive for another. Lets take crunches….an exercise I have done for over 20 years when instructing my group exercise classes, but one I never program to clients today nor do anymore myself. My concern with crunches is the amount of disc pressure caused during spinal flexion, and the gradual wear and tear of the disc rings (annulus fibrosus) that can lead to deterioration and eventually predispose the person to a prolapse. But does that mean that no one should ever do a crunch? No! But lets be honest here….no exercise is quite done to death like the crunch! It’s the excessive repetition that causes concern.
Lets look at planks…..the gold standard exercise for developing core strength. Well I occasionally perform dynamic planks (moving from forearm to hand and vice versa) but even planks have their risks. In a horizontal position the vertebrae are not as stable as when in a vertical position (where gravity provides a compressive force from one to the other keeping facet joints more stable) and this can also provide increased risks. So should planks be banned for everyone? No!
As a functional strength trainer myself, I have my OWN favourite exercises that I choose for MY abilities and injuries, and I have to admit I don’t really work my abs in isolation. I prefer to choose exercises where the body works as a unit, so I may not implement abdominal exercises specifically. In every strength training workout I always perform some kind of uni-lateral exercise (i.e. one arm, one leg) for example a one arm cable or dumbbell row, lunges, cable wood-chops, half kneeling single arm overhead dumbbell press. Any exercise where my torso has to stabilise itself in order to perform the exercise properly, and trying to stay in the vertical as much as possible (except for the one arm dumbbell row of course). Explosive exercises are also great for activating the abdominal muscles – box jumps, stair runs, sprinting, boxing, kicking (the last two are awesome as they are explosive through rotation). Rope training is also amazing for working the abs, as too are some kettle bell exercises…..and it can go on and on.
So do your WHOLE body a favour and train the WHOLE body harder and you may be surprised at how much those abs turn on!
My biggest deciding factor when choosing exercises for a person (and for myself…remember I also have a chronic disc injury that I have to live with), is what is the benefit to risk ratio? If an exercise gives me greater benefit and has lesser risk I will choose it over another that is higher risk with less benefit. Elite athletes and a lot of bodybuilders will sacrifice risk to gain that little bit more benefit – so can you see that yet again, one size does NOT fit all. So what ARE the best ab exercises? It will be different for everyone, but yes…… some are definitely better choices over others.
Oh and lets not forget the biggest deciding factor for determining whether you can SEE those abs……your eating habits! If you want to see all that hard work then you will need to do something about your food and drop some body fat.
So that’s the truth, the whole truth, and nothing but the truth. If your trainer thinks everyone should train the one way….then it might be time to upgrade to a more understanding trainer.
There are many myths surrounding health, nutrition, and fitness as most of us know, but there are none quite as big as the one on cholesterol! A little while back I came across a three-part Catalyst documentary on the ABC – it covered the truth on sugar, cholesterol, and statin drugs. It was hugely controversial and the ABC were even forced to remove these videos from their website. The other day I again saw a TV interview with two of the men on the afore-mentioned documentary who have since published a book called “The Great Cholesterol Myth”. The authors are Dr Stephen Sinatra MD who has been a cardiologist for most of his long life, and Dr Johnny Bowden PhD who is a well-respected nutritionist. What they have to say is important to help us at the very least question our beliefs and hopefully nudge us into some further investigation for ourselves.
As a society we largely believe information that is regurgitated without even looking into the facts. What I am encouraging is to at least make your opinions educated ones. It takes a long time to change perceptions, but remember we all used to believe the world was flat! We believed the myth that cholesterol caused heart disease as fact. We were taught this based on research done in the 1960’s and 70’s which has since been shown to be extremely faulty. That sort of research wouldn’t even get published if done today.
Most well-meaning doctors don’t have time to actually read the details of the research and in that research it shows pretty clearly that cholesterol doesn’t really lead to heart disease. It’s a bad predictor.
Here is some information that you may not have been aware of.
Cholesterol is an essential component for health. Here are some of its important protective uses:
- It is vital for cellular function
- Makes vitamin D in the skin
- It assists with cerebral-vascular function
- It helps with neurotransmitter function so we can think better
- It lubricates the skin
- It protects from diseases of the gastrointestinal tract and lungs
Framingham studies have shown that increased cholesterol over the age of 40 correlates to increased lifespan. (The Framingham Heart Study is a long-term, ongoing cardiovascular study on residents of the town of Framingham, Massachusetts. The study began in 1948 with 5,209 adult subjects from Framingham, and is now on its third generation of participants. It is the longest running study on heart disease).
The root cause of heart disease is inflammation, and inflammation causes the plaque that leads to heart problems. So what causes inflammation? Being overweight, what we put into our body, and SUGAR! Sugar is the villain. Sugar in your blood causes oxidative stress and plaque and you get an enormous insulin response.
Ok so what about stain drugs to reduce your cholesterol? Well they DO reduce cholesterol. But remember cholesterol isn’t the problem. By reducing it in your body you are also reducing the protective properties that cholesterol is responsible for. Plus statins have huge side effects. For the general population, for women and children, statins tend NOT to be useful. They do seem to work well with ONE population however….middle aged men with coronary disease, primarily with reduced HDL’s. Statin drugs have been shown to predispose women to diabetes and have also been linked to cancer. It has been linked to coronary calcification, memory loss, sexual dysfunction, muscle pain, and liver problems. In children statins can interfere with development….especially cognitive! Statin drugs are amazing at making pharmaceutical companies VERY rich by using their scare tactics on uneducated people.
The best things to do to reduce the risk of heart disease and to keep the heart healthy are:
- Reduce inflammation.
- Processed foods, sugar, trans fats, alcohol, omega 6 rich foods (vegetable oils) when not balanced adequately with omega 3, ALL encourage inflammation.
- Look for natural foods that have anti-inflammatory properties such as those rich in omega 3, dark leafy green vegetables, nuts, berries, apples, garlic (which helps to reduce blood pressure). Doing a google search will give more specifics.
- Get rid of toxic relationships
- Lower stress in your life (stress is a very high risk factor for heart disease)
- Getting adequate sunshine and Vitamin D (see earlier blog for information on this)
- Getting enough fresh air
- Regular exercise/physical activity
- Saturated fats CAN increase cholesterol, but more of the GOOD cholesterol (yes there is ANOTHER myth). Remember though that there are both good and bad foods that are high in saturated fats so choose the healthy natural ones like coconut oil, nuts, oily fish rather than ones like processed meats.
Keeping the heart healthy is NOT the same as lowering cholesterol!
For 99% of the population cholesterol in the diet has virtually NO effect on anything of importance! Can you hear the eggs screaming out in victory? 🙂
As far as tests are concerned, the number one medical test that could predict your risk of heart disease is the “Particle Size Test”. This test measures specifics about the bad cholesterol in your body. It measures LDL (low density lipoprotein) but not all LDL is as harmful as commonly believed. The small LDL’s are the ones that tend to attach themselves to artery walls (they are oxidized LDL’s). The large ones are not the monsters they are labelled. The small LDL’s get into the nooks and crannies of the arteries and when they bore in they explode, This causes inflammation and contributes fundamentally to the plaques and to the risk of a heart attack.
So if you are someone who likes to think for themselves, I ask you to do some further research and actually investigate the findings. Don’t just been sheep who follow the others in front who have no idea where they are going. Remember….a million wrong people are still wrong.
Happy self-awareness everyone.
Sleep is absolutely crucial to your health. Sleep is just as important as nutrition and exercise when it comes to improving your health, performance, and body composition. Good sleep helps our bodies and minds recover, keeping us lean, happy, mentally focused, and healthy. But chronically bad sleep slathers on body fat, screws up our hormones, ages us faster, increases chronic illnesses, and drains our IQ and mojo.
Often the real reason for lack of sleep is rarely long work hours or physiologic abnormalities; rather, most people lose sleep due to voluntary bedtime delay. If we were to remove forms of artificial stimulation and excessive work/life demands, humans would likely sleep for about 8 hours per night, based on the natural sleep/wake cycle of the brain.
“Sleep loss due to voluntary bedtime curtailment has become a hallmark of modern society… Chronic sleep loss, whether behavioural or sleep disorder related, may represent a novel risk factor for weight gain, insulin resistance, and Type 2 diabetes.”
Spiegel K, Leproult R, Cauter EV. Impact of sleep debt on metabolic and endocrine function. Lancet 1999;354:1435-1439.
While there are many reasons that lack of sleep could influence body fat, one of them may be the decreased growth hormone (GH), thyroid stimulating hormone (TSH), and increased cortisol, most notably in the evening. Moreover, chronic sleep restriction results in elevated sympathetic nerve activity and a slow insulin response. Pragmatically speaking, lack of sleep may lead to more body fat simply because more time spent not sleeping means more time to eat. And those junk food commercials start looking pretty appealing at 1 a.m.
Getting less than 7.5 hours of sleep each night also means that you’re at greater risk of heart attack, stroke, and sudden cardiac death than your pals who get plenty of snooze time.
Here are 8 reasons why getting a good night’s shut eye will set you up for a brighter day.
1. Weight Control
2. Increase Concentration
3. You’ll be in a great mood
4. You’ll look more attractive
5. Increased ability to make better informed decisions
6. You’ll live longer
7. Improved athletic performance and reaction time
8. You will reduce your risks of getting ill (as lack of sleep can suppress your immune system)
With a few simple strategies, you can get the high-quality, restful sleep your body and your mind deserves.
CREATE A SLEEP ROUTINE
Just like you can’t go from 0 to 100 first thing in the morning, you can’t do the reverse at night — going from “on” to “off” in a few minutes. Your body needs transition time and environmental cues to wind down.
- Keep a regular schedule – If you’re consistent, your body will know when to release calming hormones before bed, and stimulating hormones to help you wake up. You’ll feel sleepy when it’s time for bed and wake up more refreshed, often without needing an alarm.
- Limit alcohol and caffeine intake – Even though it seems like alcohol is relaxing, more than 1-2 drinks in the evening can interfere with deep sleep, as can too much caffeine. Although you may “sleep” for 7 hours, your sleep won’t be high quality, and you won’t get the recovery benefits.
- Eat and drink appropriately – Having a large meal immediately before bed can disrupt your ability to fall and stay asleep. Instead, eat a regular-sized (or even smallish) meal a few hours before bedtime. In addition, try to limit your fluids 2-3 hours before bedtime to prevent frequent waking for bathroom breaks. While total sleep time is important, uninterrupted sleep time is even better.
- Do a brain dump – We’ve all done it: Stared at the ceiling, long after lights-out, obsessing about all the things we’re supposed to do tomorrow, tossing and turning and getting more and more stressed by the minute. Whatever is in your brain, get it out and on to paper. It clears your mind for genuine relaxation
- Turn off electronics – Digital devices stimulate our brain with their light, noise, and mental demands. Unplug from allscreens — TVs, computers, phones, tables — at least 30 minutes before bed. Our brain produces melatonin as light levels decrease. This ensures deep sleep, and may also help regulate metabolism. If we have too much light at night, we don’t get proper melatonin production.
- De-stress before bed – What de-stresses you? Do that! Gentle movement — such as stretching or yoga; Reading before bed — but make sure it’s not too engaging; Meditation, deep breathing, or other relaxation exercises.
- Sleep at least seven hours – Most people need 7-9 hours of sleep per night. 7 should be your baseline. Also factor in transition time. Don’t stop what you’re doing at 9:29 and expect to be snoring by 9:30. Start moving in the direction of bed by 9:00.
- Exercise regularly – Exercising regularly helps normalise circadian rhythms, tone down the sympathetic nervous system, and regulate endocrine function. However, some people report being “revved up” by intense exercise so if this is true for you then you may wish to save the higher intensity exercises for during the day if possible.
- Take a bath or shower – Warm water before bed can help us relax and de-stress, which is key for falling asleep. A short, very cold shower may also do the trick. The logic is that cold water stimulates a strong parasympathetic nervous system response once the initial shock has passed.
OPTIMISING YOUR SLEEP ENVIRONMENT
- Keep the room as dark as possible
- Create a relaxing sleep area that is quiet and free of clutter
- Set your room at an appropriate temperature
- Use white noise if needed
- Good sleep is crucial for good health. There are no short cuts, despite what the “sleep hackers” say.
- Make good sleep a priority. Your physical, mental, and emotional wellbeing will thank you.
- Think about good sleep as a 24-hour process. What you do during your waking period will affect your sleeping period, and vice versa.
- Reinforce your natural circadian needs. When it’s supposed to be dark and quiet, make things reallydark and quiet. When it’s supposed to be bright, noisy, and stimulating, get moving with some bright light.
- Give your body and mind transition time. Allow at least 30 minutes (and preferably an hour) in the evening to slowly wind down and prepare for sleep.
- Stick to a routine. Bodies love routines and consistency. If your body knows what to expect in your day, it’ll help you wake up and doze off at the right time.
- You can’t control your actual sleep. But you cancontrol your sleep behaviorsand environment. Take charge of your actions and surroundings, be consistent, and enjoy the Zs.
It would have been my late fathers birthday a few days ago and reflecting back on his life gave me the idea for content for today’s blog. Coupled with a Precision Nutrition reading that finished with the words “Don’t just survive – THRIVE!” I was compelled to discuss this subject matter in detail.
Ok, so firstly let me set the scene with some family history. Both of my parents were born early last century – my father in 1920 and mother in 1926. Sad;y, both have now passed and each of them lived to around the age of 80 (so lifespan was very similar). However, they lived their lives VERY differently. By the time I was born my mother was in her early 40’s. All I remember growing up is her sitting in her chair watching TV and smoking like a chimney. She suffered depression quite badly and never left the house. Whenever she did anything remotely active she would be in pain for days afterwards. In my eyes, my mother was always old and frail, and though I loved her with all my heart I cry for the life that she had. My father, on the other hand, was forever out and about. He never smoked and was always out taking numerous walks or scenic drives. He was strong and capable and forever present with life and nature. Clearly, their lives were completely opposite to one another.
Quality of life is something that is very precious and often people neglect to make the effort to enhance theirs. Genetics is an important indicator for longevity and disease but your behaviour matters! Your genetics will not counteract bad behaviour. Quality of life principles are really quite simple, but like anything worth having, it requires dedication and effort.
- Physical activity. Get moving! Move more, and move with intent. Work the heart and lungs, strengthen muscles, and improve range of motion by stretching regularly.
- Nourish your body. Eat natural healthy foods with a balance of nutrients amongst all food groups; drink plenty of clean water; get adequate sunlight (without burning the skin); enjoy quality replenishing sleep;
- Nurture your mind. Take time out to relax and unwind the mind; be present with nature (earth yourself on grass, sand, sea). Explore ways to de-stress and be at peace.
- Avoid toxins. Minimise toxic foods (processed, high sugar, trans fats, additives and preservatives); give up cigarettes and control intake of alcohol. Look for other alternatives to prescription medications if needing to take them long term (some medications can be alleviated by change of lifestyle!). Research toxins that surround you everyday – your toiletries, sunscreen, household cleaning agents etc and see if there are healthier alternatives.
Yes this all takes time and effort and it isn’t going to happen all at once. But once you start focusing on health and see the results healthier behaviours can yield then the snowball effect will stem into other areas of your life. I don’t just want to exist. I want to enjoy the time I have on this earth. If quality of life is something that you are lacking, then look for ways to make improvements and bit by bit you yourself may find yourself starting to thrive!
Marketing is the main way people expose themselves to information, yet what people neglect to understand is that marketers have only ONE objective – to sell you on their point or product. Unfortunately, they often neglect to give you ALL the information and just focus on the points that will convince you to be a consumer of their product.
We live in a scare-mongering time where snippets of information can powerfully cause public behavioural shifts. Obviously, we need to be mindful of the damage that sun-abuse can cause to our bodies, but our sun-smart ways may not be as “smart” as we think!
What is Vitamin D?
Vitamin D is essential for absorbing calcium and phosphorous for strong bones. Furthermore it is now believed that this vitamin D is also needed for:
- Immune system, which helps you to fight infection
- Muscle function
- Cardiovascular function, for a healthy heart and circulation
- Respiratory system –for healthy lungs and airways
- Brain development
- Anti-cancer effects
How To Get Enough Vitamin D
The two main ways to get vitamin D are by exposing your bare skin to sunlight (ultraviolet B rays) and by taking vitamin D supplements (the best form is Vitamin D3). You can’t get the right amount of vitamin D your body needs from food and your body cannot make this vitamin on its own.
Important facts on skin exposure:
- The more skin that is exposed the faster the body absorbs Vitamin D – so larger skin areas such as legs and back are better then smaller areas such as face and arms
- You don’t need to tan or to burn your skin in order to get the vitamin D you need. Exposing your skin for a short time will make all the vitamin D your body can produce in one day. In fact, your body can produce 10,000 to 25,000 IU of vitamin D in just a little under the time it takes for your skin to turn pink.
- Skin type determines how much exposure is necessary. Fair skinned people produce less Melanin so do not need as much time in the sun as darker skinned people who produce more Melanin. Melanin protects against skin damage from too much UVB exposure, so darker skins with more melanin allow less UVB to enter the skin. With less UVB getting through the skin, less vitamin D is produced each minute.
- Your skin produces more vitamin D if you expose it during the middle of the day.
- Solariums (tanning beds) also help the body produce Vitamin D. As with sun exposure it is recommended to get half the amount of exposure that it takes for your skin to turn pink. Using low-pressure beds that have a good amount of UVB light, rather than high-intensity UVA light are also best.
- As we get older our skin has more difficulty producing Vitamin D so supplementation may be a better option
- Supplementation is also recommended for those who have little to no skin exposure to the sun during the week (i.e. indoor jobs or outdoor jobs where you are largely covered up)
What About Sun Damage & Skin Cancer?
Research to date shows that moderate but frequent sun exposure is healthy but overexposure and intense exposure can increase your risk of skin cancer.
Using sunscreen is not as recommended as using shade and clothing to protect your skin, because it hasn’t consistently been shown to prevent all types of skin cancers. But if you do want to use sunscreen, use a sunscreen that blocks both UVA light and UVB light.
If you are still anxious and concerned about skin exposure then your next best options is daily supplementations. Just ensure you are getting a good quality product supplement so do your homework.
The individual recommendations are dependent on numerous factors and it can be complicated. To read more and get a better understanding please click the following link for more in depth information:
I wanted to cover a highly misleading concept today about the “importance” of eating breakfast for weight-loss and health. Why do we believe this as “fact”? We have to stop going with the flow of the masses and remember that “a million wrong people are STILL wrong!” Try and do some thinking for yourselves by reading and analyzing credible information. The moment someone reads that something has been scientifically supported through research they blindly follow without understanding anything ABOUT the research. As a scientist myself I personally understand just how much misconception there can be around it all.
As I am an avid supporter of Precision Nutrition I did not want to reword their article and thought I would just cut and paste the basics. The full article can be read at http://www.precisionnutrition.com/skipping-breakfast-and-obesity.
Here is a snippet….
The importance of a “healthy breakfast” is nutritional gospel. Everyone from your grandma, to your personal trainer, to your favorite fitness magazine “knows” a morning meal will help you lose weight and stay lean. But is “what everyone knows” actually true?
Sure, most research on breakfast and body comp shows that breakfast eaters tend to be leaner than non-breakfast-eaters. Unfortunately, a lot of scientific research doesn’t quite “prove” what people think it does.
Yes, science is our main pathway to genuine discovery. But it’s also a human endeavor, and fallible. That’s right, despite their expertise, scientists are people too. As such, they (and their research) can be influenced by many factors, including:
- Worrying about where their next research dollars are coming from.
- Their own deeply rooted assumptions.
- Who’s running their lab or overseeing their work.
- What’s “hot” or “trendy” in their field.
- Sticking it to their arch-rival, Dr. Smug Loudmouth.
- Getting published in The Bigname Journal.
- Their upcoming tenure file review.
Yep, even though we like to think of the scientific process as distant from the petty inter-social nonsense of daily life, it’s not. In fact, it can sometimes resemble a soap opera. That’s why, when it comes to interpreting the results of their own studies, or other peoples, scientists might mess up.
Their needs and their beliefs can distort the way they see the evidence, and what they make of it. This can lead to biased reporting and faulty recommendations. An even bigger problem? This can lead to wide-spread mistaken beliefs among non-scientist people. But is this a rare occurrence? Not really. It happens more often than you think. Take, for example, breakfast. While study after study may appear to support the idea that breakfast is the most important meal of the day, it turns out there has never been a properly randomized (causal) study that “proves” the positive effects of breakfast!
Generally, scientists are just as prone to error as anybody else! We see it time and time again. Small biases, and tiny language differences, cause a whisper-down-the-lane effect. And “truths” are accepted that were never true in the first place. Specifically, there’s very little evidence to suggest that skipping breakfast will cause you to get fat. Sure, we can establish a correlation between skipping breakfast and being overweight. But many factors — from genetics, to a general lack of interest in health — could explain this relationship. We just don’t know that one causes the other.
What to do
For those of you looking to lose or control your weight…should you eat a big breakfast or not? Well, here are some guidelines.
First, remember that you’re unique. We don’t know all the relevant factors yet. You may be someone who thrives on breakfast. Or you may not.
Observe your own body’s cues. Experiment on yourself. Does eating breakfast make you feel better and more in control of the rest of your day’s consumption? Or does it make you weirdly ravenous later on? When it comes to making decisions, your body’s actual response is the only evidence that counts.
Try different breakfast types. What happens if you exchange one food source (say, processed carbs) for another (say, lean protein)? How do you feel? How does your body react?
Whatever you eat, whenever you eat, stick with your fundamental healthy habits. Eat slowly, watch your portion size, avoid distractions, and pay attention to how you feel. And, of course, try not to get carried away by rumors. Even if they seemed backed by scientists. Because those same scientists may be struggling even more than you are.
