Vitamin D
Resolve to be healthy in 2012!
I love the holidays, but hate the expectations that come with the New Year. But, as my friend and colleague Dr. Jillian Murphy, ND points out, if we don’t take time to think about resolutions would we ever think about change and how to make ourselves better?
So, I thought I’d make things a bit easier for those of you who are hoping to make a resolution (or two) and need some help sticking with it! Here’s a quick list of small things that can make a big impact on your overall quality of life and health.
1. Take a multivitamin. This basic step is such a great insurance policy. A good quality supplement will be free of fillers, come in capsule form and ideally be taken in divided doses (ie. 2-3x/day). One-a-day vitamins are convenient, but you won’t absorb as much as you will from a multi-dose vitamin. And, if you have any concerns about the risks and benefits of a daily multi-vitamin, have a look through this report from the Harvard School of Public Health. It does a great job of explaining why you’re better off taking one!
2. Eat a reliable source of probiotics. Good bacteria like those found in fermented foods such as yogurt, kefir and saurkraut are proving to be more and more important to overall health than ever before. Not only are they involved in maintaining a healthy gut, they also play am important role in maintaining a healthy immune system. For example, a Cochrane Review found that those who took probiotics were less like to suffer with upper respiratory infections. These “good bacteria” are also important for those with autoimmune conditions, allergies and eczema. Diet should be sufficient to maintain a healthy population of gut bacteria, but you may need to supplement if you’ve taken antibiotics, recently travelled, take certain medications or have a GI illness. In these cases, we’re happy to help.
3. Eat your Greens! Yes, I know you’ve heard this before, but do you know why? Leafy green vegetables such as spinach, kale, swiss chard and the like are loaded with phytonutrients. Dark leafy greens are a rich source of vitamin C, K, E, and B, as well as iron, calcium (must be cooked), and fiber, which are essential for good health. Recent studies have shown that Vitamin K plays an important role in preventing osteoporosis, arthritis, diabetes, and atherosclerosis. Vitamin E has been shown to prevent skin cancer. Greens also contain beta carotene (converts to vitamin A), lutein, and zeaxanthin which are powerful antioxidants.
4. Get rid of “white food”. Most people know that white bread isn’t the best choice, but other white foods like white potato and white rice should also be limited. Choose sweet potato, brown rice, quinoa or millet more often! Insulin resistance is on the rise, and “white foods” should be a “less often” choice.
5. Have your Vitamin D status assessed. There’s a growing body of evidence about the role of vitamin D in maintaining health, and it’s very far reaching (read www.vitamindcouncil.org for more info. In Nova Scotia, the minimum level required to maintain bone health is 75 nmol/L, and I can’t tell you the number of patients I see with numbers well below that. If you haven’t had this simple blood test, ask your doctor to check it for you at your next appointment. And, if you are found to be deficient, touch base with us on how best to optimize your levels.
Hope 2012 is full of peace, health and wellness for you and your family!
Seasonal Affective Disorder – aka ‘Winter Blues’
As we get ready to move the clocks back next weekend, people who suffer from Seasonal Affective Disorder (SAD) begin to dread the coming months. Those who suffer from SAD begin to experience:
- fatigue
- depression
- crying spells
- irritability
- trouble concentrating
- body aches
- change in sleep patterns
- decreased activity level
- overeating, especially of carbohydrates.
What causes SAD?
- Your biological clock (circadian rhythm): The reduced level of sunlight in fall and winter may disrupt your body’s internal clock, which lets you know when you should sleep or be awake. This disruption of your circadian rhythm may lead to feelings of depression.
- Serotonin levels: A drop in serotonin, a brain chemical (neurotransmitter) that affects mood, might play a role in seasonal affective disorder. Reduced sunlight can cause a drop in serotonin that may trigger depression.
- Melatonin levels: The change in season can disrupt the balance of the natural hormone melatonin, which plays a role in sleep patterns and mood.
- Vitamin D Defeciency: Because vitamin D is produced when our skin is exposed to sunlight, declining levels of Vitamin D may play a role in SAD.
- Living far from the equator. Seasonal affective disorder appears to be more common among people who live far north or south of the equator. This may be due to decreased sunlight during the winter, and longer days during the summer months.
Treating SAD
Light therapy
In high-intensity, full-spectrum light therapy, also called phototherapy, you sit a few feet from a specialized light therapy box so that you’re exposed to bright light. Light therapy mimics outdoor light and appears to cause a change in brain chemicals linked to mood.
Light therapy is a good place to start for seasonal affective disorder. It generally starts working in two to four days and causes few side effects.
Enjoy the sunshine!
Make sure you take advantage of sunny days, and try to get some early morning sunlight exposure. A brisk walk around the block, or walking to work is a great idea.
Exercise
As with any type of depression, exercise helps to relieve symptoms and has many other benefits.
Supplements
Work with your ND or MD to ensure that you have adequate stores of Vitamin D. This vitamin is measured using either a blood or saliva test. Some people need to take much more than the recommended 1000 IU/day to meet their needs.
Melatonin is another interesting supplmement, which many people find helpful during the winter months, especially when sleep disruptions are present. Most people can safely start taking melatonin, beginning with 1-3 mg before bed. As always, consult with your ND or MD before taking mealtonin if you are taking any prescription medications.
The Naturopathic Approach
As with any symptom or condition, we work with you to get to the root cause of illness. We asses diet, lifestyle and environment to help you achieve health and wellness. SAD is a condition which responds very well to naturopathic medicine, and has helped many people get through the winter with a little bit more sunshine.
