Have a Healthier Winter with Vitamin D

We have been lucky this January to have so many sunny days, but are we still getting enough vitamin D? I know that most days I am working inside and only see the sun when I am taking care of my chickens in the morning. If we don’t get enough sun and our vitamin D levels go down, we can start suffering from the winter grumpies, or seasonal affective disorder, as it is technically known.

I often encourage my patients to take a low dose of vitamin D during the winter or all year long, especially if they are taking a calcium supplement. I am not necessarily a fan of the higher doses such as 5000 IU once a day, since too much of a good thing isn’t always a good thing. Vitamin D is actually a hormone that regulates calcium metabolism, and as with hormone replacement therapy, there is a normal range for our bodies. Unless someone is deficient, the higher doses might actually reduce some of the vitamin D benefits. Additionally, sometimes we need to dig deeper. If someone is vitamin D deficient, it can be due to excessive inflammation in the body, and this may need to be addressed more than the vitamin D levels

Adequate vitamin D is associated with many health benefits including stronger bones, lower rates of influenza, reduced blood pressure, and reduced breast and colon cancer risk, but some of the benefits go away if people take too much. Therefore, I have been encouraging people who don’t know their vitamin D levels to stick with doses around 1000 IU. One study demonstrated that just 800 IU a day slightly reduced mortality due to any cause in elderly people, mainly women.

So if you are dealing with the wintertime blues, considering adding a little vitamin D to your routine, but remember don’t overdo it.

And get some sun when you can!

The Buzz About Bone Broth

When I first heard of bone broth, I had no idea what people were talking about. I mean obviously it was a broth made from bones, but what made it special. So I looked up a recipe. People were simmering bones in water for long periods of time to extract the minerals and other nutrients.

Then I realized I had made bone broth on and off for the last 15 years. I had just called it broth. Fifteen years ago, I was a vegetarian so I wasn’t making it for myself, but every time my cats got sick, I would turn to my copy of Dr. Pitcairn’s Complete Guide to Natural Health for Cats and Dogs. He recommended that a special chicken broth be made to help sick animals recover faster. So even though I didn’t eat meat myself, I bought a chicken and made chicken broth. I don’t even remember what I did with the meat, but after I had made the normal chicken broth, I put the bones back in it and cooked it for many more hours. Dr. Pitcairn recommended added a few tablespoons of vinegar to the broth to help get the minerals out of the bones faster. This made total sense to me so it became a regular practice when I had a sick cat.

Eventually, I started eating meat and now I even raise my own chickens. Whenever I cook chicken, I like to save the bones in the freezer. When I have enough of them, I stick them in a pot and add enough water to cover the bones and a few tablespoons of vinegar. Then I cook it for as long as I reasonable can, adding more water if needed. Many people do this in a crockpot so they can leave it simmering for 24-48 hours. If you can cook it long enough, the bones become easy to break and you know you have extracted most of the nutrients. After whatever period of time, just strain and enjoy. I often freeze any extra for later use. If you are not ready to make your own, companies are starting to sell real bone broth ready to use.

Bone broths have been a part of traditional cooking throughout the world. For instance, I am also a huge fan of pho, the Vietnamese soup made with beef bone broth. If you asked a Vietnamese granny for her recipe, I bet she would tell you to simmer the broth at least overnight. Bone broths can be used as the base for any dish you would normally make with broth, such as soup, sauces, or as the cooking liquid for whole grains. Or you can drink it hot with salt and any other spices.

Bone broth is going to be rich in minerals as well as gelatin, glucosamine and other nutrients our bodies need. In addition to calcium, bone broth contains magnesium, potassium, phosphorus and a host of other trace minerals. We can also get collagen, gelatin, and glucosamine from the connective tissue on the bones. These combinations of nutrients are obviously good for bone health, but they are also likely to enhance the health of your hair, skin, and nails. Bone broth might also help keep your joints and connective tissues in good shape. Of course, many other conditions could benefit from this boost of minerals and nutrients, from insomnia to heart palpitations. And at this time of year, remember that broth is the traditional remedy during cold and flu season (or for a sick cat).

Is Vitamin K2 the New Vitamin D?

Vitamin D has received a lot of interest in the last few years as an essential nutrient to possibly help prevent serious health issues. Not as much thought has been given to its helper Vitamin K, but I think this is going to change. Several of the conditions that are thought to be associated with vitamin D deficiency, such as osteoporosis, cardiovascular disease, and cancer, as also linked with vitamin K deficit.

Like vitamin D, vitamin K is a fat-soluble vitamin that occurs in several forms. The most commonly known form is vitamin K1, which is necessary for proper blood clotting. Vitamin K2 is the form that is gaining interest right now for its importance in bone and heart health. Sources of vitamin K2 are natto (fermented soybeans), tempeh, grass fed butter and beef, eggs, cheese, and possibly sauerkraut and other fermented vegetables. It is also sold as a dietary supplement under the name MK-7, which stands for menaquinone-7 the scientific name for vitamin K2.

Most of what vitamin K does in the body is help different protein handle calcium, but it is through the appropriate use of calcium that vitamin K has so many benefits.
Vitamin K helps certain proteins hold on to calcium. For instance in bone formation, a protein called osteocalcin needs vitamin K to be able to deposit calcium in the bones. This is why the combination of calcium, vitamin D, and vitamin K was superior for helping improve bone density than was calcium and vitamin D alone in a 2012 study.

Some recent studies have linked calcium intake to increased hardening of the arteries. My hypothesis is that if we don’t have adequate vitamin K2, taking calcium may be an issue for heart health. Vitamin K2 is an essential part of a protein in our artery walls that helps prevent calcium from being deposited in the arteries. Indeed, a few studies have demonstrated that higher vitamin K2 intake is associated with lower rates of cardiovascular disease. So I always tell my patients if they take calcium, make sure they also have adequate levels of vitamin D and vitamin K2 to help ensure the calcium is going to the bones where we want it and not to the arteries.
