What Does Vit D Do in the Body? There are a number of important jobs that Vit D does:
Measuring Vitamin D status Generally the next question I get from a lot of people is how do I know if I'm getting enough Vit D. Currently the best way to do this is to measure it in the blood by look at the blood or serum concentration of calcidiol (D2). Wait, didn't I say that the active form is calctriol (D3)? The reason is the 1/2 life of D3 is too short to make it a good indicator as well as it being regulated highly regulated by parathyroid hormone, calcium and phosphate. D3 levels also do not normally decrease significantly until Vit D deficiency is severe. How Much Vit D is Needed? If we understand how important Vit D is, the next thing my patients often ask is how much do I need? As we mentioned above, to know if you personally are getting enough, getting your levels checked is going to be the best option. However, there are general recommendations made by the government which are based on what is called the RDA or Required Daily Allowance. This depends on the average of what works best for a healthy population and maintaining basic requirements for health. In the case of Vit D that's enough to bone health and calcium metabolism, and then in addition the RDA is set based on minimal sun exposure as well. All of this combined, the current daily recommendation for adults and children over 4 years is 400 IU. If we're trying to raise our levels of Vit D, 400 IU is definitely not going to be enough.
Can I Get Enough from the Sun? Most people meet at least some of their Vit D requirements from the sun. However, what most people don't realize is that this depends. You need to be outside at the right time of day, and depending on where you live, time of year as well. We need to be exposed to UVB rays at wavelengths of 290-320 nanometers. Other factors that can affect this are: cloud cover, smog, melanin content of your skin (the darker your skin the more difficult it is to 'absorb' enough sun). Optimal Sun Exposure The factors previously mentioned and current research that's been done still makes it challenging to know exactly what the right amount of sun exposure is for each person. However, these guidelines are helpful to get some helpful exposure: - In general, approx 5-30 mins of sun exposure between 10am -3 pm twice a week to arms, face, neck. legs or back without sunscreen [NOTE: if you are monitoring risk for skin cancer, than keep in mind any recommendations from your healthcare provider] - Spring, Summer and Fall are the optimal times of year, particularly those who live in more northern latitudes
Take Home Message - Vit D is important for our overall health, and we're still figuring out the full extent of what this entails - Vit D is present in the diet, and through exposure to the sun we are able to synthesize Vit D - The drawback is it's tough to determine how much we're getting, so many of us will need to supplement with it at times - There are safe and unsafe levels of Vit D, and finding out what works best for us personally is likely going to require getting our levels checked periodically.

The Stats In the US: · Number of people in the U.S. who have either allergy or asthma symptoms: 1 in 5. · Percentage of the U.S. population that tests positive to one or more allergens: 55%. Internationally: The prevalence of asthma in different countries varies widely, but the disparity is narrowing due to rising prevalence in low and middle income countries and plateauing in high income countries.
Suffering from allergies can be a very irritating experience. If you or your child is suffering from allergies, it is best to take them to a Naturopathic Doctor who can perform a proper assessment and form a treatment plan that will address your/your child’s needs. Always speak to your health care provider before beginning any new medications or supplements. References: Allergy Statistics and Facts. WebMD. Reviewed by Johnson, K.

I completely understand how important, small, manageable changes are to creating success! I see it all the time with my patients and the research also supports this approach. Therefore, I will only mention 3 small things you can do to make a big impact on your eating habits and your health.
There you have it. Some very simple changes you can make to how you eat to improve the quality of your diet. Now I am not saying you have to even do this all at once, pick one and start with that. Then you can look at adding the others over time. If you never start, you'll never get the benefits, but if you try to change everything at once you'll feel overwhelmed and eventually you will drop everything.
Have questions about these tips or how to have better eating habits? Talk to me about it. I love helping people make gradual, positive changes that benefit their health and well being.

Why do we need to worry about sugar? Sugar in the blood is not a bad thing on its own. In fact, without this important fuel we wouldn’t last very long. However, like most things, in the right amount we stay healthy, but when we have too little sugar or too much, that’s when problems arise. Our main method of procuring this fuel is eating and drinking. Anything we consume, our body breaks down into it’s most basic building blocks, glucose, which is sugar, being one of them. Once broken down, the body shuttles the glucose to where it’s needed. If you’re playing a game of tag, then you’re going to need glucose for your muscles. If you’re studying for a big test, then you need glucose for your brain. The blood is simply the highway system in your body that transports the glucose (along with many other things) throughout the body until it reaches it’s final destination.
What can we do? Eating Well We know that balance is important, but what are some easy and crucial things we can do to improve our blood sugar balance. One, you may have guessed, is being mindful of what you eat! Proper nutrition is really a cornerstone of good health. Start with eating a diet focused on good whole foods, which includes 5-10 servings of fruit and vegetables a day, whole grains (complex carbs), good proteins and healthy fats. Then avoiding excess sugar, like soft drinks. Did you know that there can be as many as 6-10 tbsp of sugar in 1 can of pop? Another helpful trick is to have either protein or fat with each meal. Not only do they help you feel more full for longer, they also modulate the rush of sugar coming into the body. If we’re looking at a curve of blood sugar levels, this is what happens if we have sugar by itself, a big spike and then decline about an hour to a few hours later. This is why people who have a chocolate bar for their afternoon snack feel like they have lots of energy and focus for the first hour or so after, but end up feeling more tired later on when their blood sugar plummets. If you eat fat or protein with your other foods, it helps to temper this spike in blood sugar so you don’t have a huge increase and subsequent decrease of blood sugar and corresponding energy levels.
Blood sugar levels have a story to tell about our health, and every choice you make with your diet and lifestyle habits writes that story. Make sure you make the right choices for you: eat right, exercise and modify your stress. Your family and your future self will thank you for taking steps to ensure that your blood sugar story is writing about a long and healthy future.

Cold and Flu season stats To start, there are over 200 different viruses cause influenza and influenza-like illness (fever, headaches, aches and pains, coughs, runny nose). According to a recent Cochrane review, the flu vaccine might only be effective against Influenza A and B, which represents about 10% of all circulating viruses (Jefferson et al, 2013). The authors’ conclusion from that review was, “Influenza vaccines have a modest effect in reducing influenza symptoms and working days lost. There is no evidence that they affect complications, such as pneumonia, or transmission.” (Jefferson et al., 2013). Period of Contagiousness You may be able to pass on the flu to someone else before you know you are sick, as well as while you are sick. Most healthy adults may be able to infect others beginning 1 day before symptoms develop and up to 5 to 7 days after becoming sick. Some people, especially young children and people with weakened immune systems, might be able to infect others for an even longer time. How Flu Spreads Most experts believe that flu viruses spread mainly by droplets made when people with the flu cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby. Less often, a person might also get flu by touching a surface or object that has flu virus on it and then touching their own mouth, eyes or possibly their nose.
Additional Helpful Measures Think drinking tea is just for your grandma? Well think again! Herbal Teas In a Harvard study, they found that people who drank 5 cups a day of black tea for 2 weeks had 10 times more virus-fighting interferon in their blood than others who drank a placebo hot drink. The amino acid responsible for this immune boost, L-theanine, is abundant in both black and green tea—decaf versions have it, too. Your optimal dose: Several cups daily. To get up to five times more antioxidants from your tea bags, bob them up and down while you brew.
Infusion vs. Decoction
An infusion is a water-based preparation made by steeping leaves, flowers, and other non-woody parts of a plant in either hot or cold water. The traditional cup of herb tea is the archetypal infusion. A decoction is also water based, but it’s done by gently simmering the herb in boiling water. This method is used for tougher plant parts, such as roots, barks and seeds. Powders: What are they good for? Usually when people think of tea they think of the leaves and flowers of the plant in a cup of hot water. However, there are certain herbs that are better made into an infusion using the powdered form. For example, some herbs are rich in volatile oils that are medicinally useful and when boiled will evaporate and be lost. Valerian root is an example of a woody part that would be better ground to powder and prepared as an infusion. The preparation method usually depends on the use of the herb. This is why it is important to consult with a trained practitioner because they can help you select the most appropriate herb and preparation method based on your particular health concerns.
