Winter Health & Vitamin D

Nova Health Club • November 30, 2024

Are You Getting Enough Sunshine & Vitamin D?

Two things we lack during the winter are sunshine and, consequently, vitamin D. In our northern climate, most of the sun's UVB rays are absorbed by the ozone layer, meaning we may struggle to produce any vitamin D at all during the winter months. This makes winter supplementation of vitamin D extremely important!

 

The term “vitamin D” refers to various fat-soluble vitamin variants all of which are cholesterol-like substances. ️Functionally, vitamin D works more like a hormone than a vitamin and is closely linked to the work of the parathyroid glands.


There is no other vitamin that requires more whole-body participation than vitamin D. The skin, bloodstream, liver, and kidneys all contribute to the formation of fully active vitamin D. With that said, fully active vitamin D is referred to as calcitriol, or vitamin D3 (which you may see on supplement labels).



Vitamin D & Bone Density


  • Vitamin D is crucial for strong bones because it regulates calcium metabolism and helps the body absorb and use phosphorus.
  • Without enough vitamin D, calcium and phosphorus levels drop, forcing the body to pull these minerals from bones, weakening them over time.
  • This can lead to conditions like osteomalacia (soft bones) in adults or rickets in children. Maintaining sufficient vitamin D ensures proper bone density and strength.

 


Boosts Immune Function


  • Vitamin D plays a crucial role in the immune system. It enhances the function of immune cells, such as T-cells and macrophages, which protect the body against pathogens.
  • It also promotes the production of antimicrobial peptides which help the body fight off bacterial, viral, and fungal infections.
  • Studies suggest that individuals with low vitamin D levels are more susceptible to illnesses like respiratory infections, including the flu and COVID-19.



Improves Mood and Combats Depression


  • Vitamin D's influence on mood stems from its role in the production of serotonin, a neurotransmitter linked to feelings of well-being and happiness.
  • Low levels of vitamin D are associated with a higher risk of mood disorders, including depression and seasonal affective disorder (SAD).
  • Additionally, it’s believed that vitamin D helps regulate the hypothalamic-pituitary-adrenal (HPA) axis, which controls stress responses, further contributing to its mood-stabilizing effects.



How to Get Vitamin D

 

Vitamin D can be found in fish liver oil and cod liver oil. It’s important to note that the animal-derived forms of vitamin D may be the most desirable supplementation form as the body is able to convert them into fully active vitamin D3 (calcitriol). The plant derived form is called vitamin D2 and does not appear to have the same functions as vitamin D3.


Unless you are eating a lot of wild caught fish, supplementation of vitamin D becomes very important during the winter months. Supplementing with both a high quality liquid fish oil or fish oil capsules as well as vitamin D is a wise decision for anyone getting little sun or living in northern climates.

 

️As mentioned, northern populations have been shown to have low levels of vitamin D. Research conducted at the University of Calgary concluded that virtually 100% of all Canadians are vitamin D deficient during some part of the year when sunlight exposure is scarce. So now the question becomes:



How Much Do We Need?

 

As a general rule of thumb, the Canadian RDA (Recommended Daily Allowance) for children and adults aged 9-70 should intake 600IU of vitamin D per day, with adults 70+ getting 800IU. This number however is usually the minimum amount and most people have other considerations that would support taking more vitamin D per day. It may be worth conducting blood work to determine how deficient you are in Vitamin D. This will determine how much you should supplement with. Most adults however find no negative effect by supplementing with >3000-5000IU during the winter months.


In addition to supplementation, whenever possible try to be outside when the sun is shining. This can be a challenge with the shorter days however even the smallest bit of sunshine on your face not only helps with vitamin D but will greatly enhance your mood. Sunlight on its own, even in the winter is essential to our health.



Taking Action


  1. Prioritize getting outside when you can, especially around noon hour when our ability to absorb and use sunlight is at its highest.
  2. Allow natural light into your surroundings during the day. Work near a window, pull back the drapes and take frequent breaks to pop your head out the door.
  3. Consider acquiring a SAD lamp. These lamps mimic natural daylight and can be very useful in replacing natural sunlight when you can't get enough.
  4. Eating a diet rich in omega-3s from fish and high-quality meats. If this isn't feasible, supplementing with omega-3s and vitamin D is vital—and even if your diet is high in omega-3s, adding these supplements can still be beneficial to ensure optimal levels.



Vitamin D Supplementation


When purchasing any supplement, it is important to look for a brand that is of clinical grade. Avoid brands like Jamieson or Kirkland and go for brands like Designs For Health, Can Prev or Metagenics. You can order vitamin D and fish oil below with 15% off until Feb 28, 2025.

It's that time of year again where Halloween candy is everywhere - especially if you have children who are in the trick or treating age. We all know that candy is unhealthy and we are aware of sugar's detrimental effects on our health, from weight gain to cavities... But do you know the risks in eating Halloween candy that go beyond weight gain and cavities? While sugar is certainly a concern, other ingredients in many popular candies can chip away at your health and well-being. The Deceptive Allure of Halloween Treats While eating Halloween candy can be a nostalgic pleasure, the ingredients list tells a different story. I personally love Halloween but about 7 years ago I went clean and gave up Halloween candy for good because I learned it is much more than a sugar problem… Beyond sugar, are ingredients like hydrogenated oils, high-fructose corn syrup, artificial colors, titanium dioxide and common allergens like wheat, corn, dairy, and soy. These ingredients can wreak havoc on our bodies, leading to a host of negative health effects that most consumers overlook. Beware: 5 Ingredients in Halloween Candy With Negative Health Effects 1. Hydrogenated Oils: Hidden Fats Hydrogenated oils transform liquid oils into solid fats and enhance texture and shelf life. These trans fats are notorious for raising bad cholesterol levels, increasing the risk of heart disease and causing inflammation in the body. Look out for the word ‘Hydrogenated’ in candies like Skittles or Starburst 2. High-Fructose Corn Syrup (HFCS): A Sweet Sabotage HFCS is another frequent offender. It’s a cheap, sweet alternative to sugar that can lead to rapid spikes in blood sugar levels and cravings. Overconsumption of HFCS has been linked to obesity, insulin resistance and fatty liver disease. Many people consume HFCS without even realizing it. Candies like Oh Henry and other chocolate bars have HFCS. 3. Artificial Colors: A Rainbow of Risks The colors that make Halloween candy so visually appealing are often the result of artificial colorings like Red 40, Yellow 5 (Tartrazine), Yellow 6 (Sunset Yellow) and Blue 1. Studies have shown links between these artificial colors and hyperactivity in children, as well as allergic reactions as well. Here are some of your Halloween favorites with these colors: Skittles , Maynards , Sour Patch Kids , Jolly Rancher , Twizzlers , Starburst and M&M’s 4. Titanium Dioxide: The White Truth Titanium dioxide is used in many candies to enhance their whiteness and opacity. It is a detergent that damages your gut and decreases your gut microbiome. Any candy that has a white center, like Skittles is known to use this ingredient. 5. Allergens: Hidden Dangers for Sensitive Individuals Finally, we can’t forget the processed allergens like wheat, corn, dairy and soy in many candies like Mars or Snickers . Those who are highly allergic know to stay away from foods with these ingredients but what about the low grade allergic response that most people ignore? Hives, scratchy through, congestions, asthma, sneezing, itchy eyes and mild GI discomfort are all effects of these allergens. The Scary Reality Halloween is a fun time but we’ve really thrown in the towel when it comes to our health based on the things we are accepting as ok. We've created a society where we buy the cheapest, lowest quality candies to give to our children (and ourselves). Most, if not all of the mainstream candy companies produce products that are high in chemicals to preserve shelf life, to entice our eyeballs and to stimulate our brain to want more the moment it hits our palette. We've also bought into the idea that it's ok because it is just once a year... but the reality is that this food is everywhere all the time. If it was just one day on Oct 31 then sure - that could be ok, but most children are coming home with more than 10lbs of candy that they consume over the next 30 days. It’s no wonder why so many of us suffer with health issues including our children. Modern children are being diagnosed with more health problems than previous generations. Things like childhood depression/anxiety, food allergies, ADHD, autism, eczema and obesity are just some of the things we are seeing more of. Stay Vigilant and Read Labels Can we blame our poor health all on Halloween candy? Certainly not - it's more than just candy in October however the amount of candy with the above ingredients being consumed during Halloween and through the year is definitely a contributor. So when it comes to candy, watch out for the sugar but it’s time to wake up to the other ingredients that are damaging us. The best thing to do is read the labels and be aware of what you choose to consume. And hopefully in time we choose to buy 'treats' that are not filled with chemicals. Next year, choose to buy healthier options versus the mainstream candy we grew up with. Healthier Alternatives Here are some options to consider instead of the mainstream low quality garbage that we've been accustomed too: Chocolate Bars Unreal Coconut Bars : This company is on point with way healthier ingredients than the mainstream. They carry an assortment of candies beyond just the coconut bar (which is one of my faves). Granola Bars Made Good : You've probably seen this brand around in stores - specializing in gluten free healthier granola bars. Cookies Simple Mills : Making cookies and baked goods gluten free and with sweeteners that have a lower glycemic index than regular sugar (less of a blood sugar spike) Candies Smart Sweets : Candies without all the artificial colors and high sugar. There are more brands out there but you have to be on your toes when buying. Pay attention to brands, scrutinize the ingredient list and pay the extra money. Every dollar you spend is a vote - the more we vote for the better products for our health, the lower the cost will end up being in the future.

Having trouble controlling the intake of Halloween candy? Unless you are a disciplined ninja or equipped with helpful restraint tactics, you end up eating too much of this low quality, highly processed junk food. If you are someone with a sweet tooth then you are in luck! Here are 5 tactics that will help you avoid eating too much (if any) candy this Halloween. 1)Don’t Skip Meals or Snacks Skipping meals and snacks creates stress on your body and a stressed body is more likely to have sugar cravings. Self control becomes extremely difficult when you're underfed. If candy appears it is much harder to resist because your body is lacking energy, vitamins and minerals. If you eat a solid meal along with healthy snacks throughout the day (ie: protein shake, apple and almonds) I guarantee that it will be hard to eat candy. 2)Eat Enough Protein On the heels of not skipping meals, make sure each meal has enough protein. Meals that are low in protein mean that they are higher in carbs. As a result you will deal with blood sugar dips and greater hunger, weakening your resistance to candy. How much protein? This differs between people but generally you aim to have at least 0.8 grams of protein per pound of ideal body weight. The more active you are, the more protein you will require. 3)Stay Hydrated Being dehydrated will make you feel hungry even when you are not actually hungry. As a result you are more likely to have the urge to grab a sweet from the candy bowl. The simple solution is to just drink enough water throughout the day. How much water?

By then it’s too late. This may sound strange but as you are picking up the candy - say out loud “I am going to eat this candy” (even if no one is around). This helps you become more aware of your actions, encourages mindfulness, and engages your logical mind. 5)Educate Yourself The scary truth is that mainstream Halloween candy is some of the worst food you can put into your body. Most of these candies contain highly inflammatory ingredients, allergens, and toxins known to disrupt everything from the gut microbiome to DNA, potentially contributing to ADHD symptoms and triggering allergies… And that’s without commenting on the effects of sugar that most of us already are aware of. Eating certain candies can be just as bad as smoking a cigarette! Give these tactics a try - they should help you to say no to Halloween junk food this year. If you are still having trouble, you can attempt a ‘clean sweep’ by throwing it all into the garbage… If you still have a sweet craving, have some dark chocolate or walk to the best bakery in town and buy yourself a $10 chocolate croissant :) Happy (Healthy) Halloween!

Do Hard Things Now, So Life Becomes Easier Later Modern humans default to the easy way but it's not our fault... Throughout human history, we were wired to survive constant hardship - scarcity of food, threats from predators, harsh environments and manual labor for everything. Our DNA evolved for survival in these conditions, not for modern living. Imagine an early human stumbling across a fruit tree. It made sense to gorge - there was no telling when the next meal would come. The human who gorged had a higher chance of survival than the human who only ate a few pieces of fruit. Practicing self-control in an environment of scarcity would have been a death sentence. Likewise, if given a chance to rest instead of walking miles or hunting, rest was the obvious choice. The problem? Our genes haven’t caught up with modern life. Today, food is everywhere. We don’t have to fight to meet our basic needs. Technology does the heavy lifting, cars replace walking, entertainment is on-demand and calorie-dense foods are always within reach. Left unchecked, our instincts will always lean toward easy options like overeating unhealthy foods (that are so easily accessible) or driving to the store instead of walking. In other words, we’re still hardwired to take the path of least resistance. But here’s the catch: Choosing easy now often means a harder life later and choosing hard now often means an easier life later. Most modern humans are overweight, stressed, tired and dealing with chronic health problems because we’re following outdated survival programming that no longer serves us. It’s time to become aware of these defaults. To override them. To consciously choose the hard thing - because doing hard things is what actually makes life easier in the long run. Hard things like: Going to bed on time instead of watching another episode Preparing a healthy meal instead of grabbing fast food Moving your body instead of sitting all day Walking or biking to the store instead of driving Managing stress with deep breaths and fresh air instead of pouring a drink Looking at your habits instead of masking symptoms with medication It might feel uncomfortable because it goes against everything your biological programming is urging you to do. But that’s exactly why it matters. Don’t think of it as punishment or sacrifice. Think of it as an investment. Every time you take the stairs instead of the elevator, cook instead of order out, or put your phone down to truly rest, you’re building a life that’s easier, richer, and more fulfilling down the road. And remember: Do easy things, and you’ll have a hard life. Do hard things, and you’ll have an easy life. Most of the above information is probably not new to you. That’s because we live in the information age with the internet and now AI - we already know what it is we need to do. The problem however is implementation. This is where having a customized plan and accountability comes in.
