Do You Need Vitamin D and How To Get It
Vitamin D (calciferol) is a fat soluble vitamin that plays a very important and vital role in our body. It promotes healthy bones and teeth by assisting in the absorption of calcium and phosphorus, can reduce cancer cell growth, reduce risk of infection, regulate insulin, reduce inflammation. and some observational studies have documented an association between vitamin D deficiency and increased incidence and severity of the coronavirus disease, COVID-19. Vitamin D deficiency can lead to weakened bones, and increased risk of disease. Severe deficiency can lead to Rickets, Osteomalacia (softening of bones, and weakened muscles and pain. We get vitamin D from direct sunlight on our skin and then it is converted in the liver and kidneys. You only need approximately 15 minutes of outdoor UVB rays to synthesize Vitamin D.People with a dark complexion synthesize less vitamin D on exposure to sunlight than those with light-colored skin. Genetics, age, obesity, CKD, magnesium deficiency, inflammatory bowel disease and malabsorption disorders can also impact the absorption of Vitamin D. In the winter months, it is difficult to generate Vitamin D. Two other ways to get Vitamin D are through food and supplements.
Foods that contain Vitamin D include:
- Fatty fish such as salmon, trout and tuna
- Egg yolks
- Fortified foods such as milk, cereal and milk alternatives
- Mushrooms
- Cod liver oil
- Beef
- Cheddar cheese
I tend to recommend an oil based supplement for most adults, but more isn’t necessarily better. Since Vitamin D is fat soluble the body does not flush it out the way it does water soluble vitamins such as Vitamin C, so it can reach toxic levels. Some signs you are taking in too much Vitamin D include:
- loss of appetite
- dry mouth
- a metallic taste
- vomiting
- constipation
- diarreah
There are also drug interactions with Vitamin D supplementation: Medications should not be taken at the same time as Vitamin D because they can decrease the intestinal absorption of vitamin D: Questran, Colestid, Xenical, and mineral oil. Certain medications increase the metabolism of Vitamin D and may decrease serum 25-hydroxyvitamin D concentrations: Dilantin, Cerebyx, Luminal, Tegretol, and Rimactane. PPI’s, used for acid reflux: omeprazole, lansoprazole might interfere with calcium absorption and increase the risk of fracture, so people taking these drugs should be taking Vitamin D. If you are on medications, you should always check with your doctor to see the effect of those medications on supplements and need for added nutrients.
The recommended base dosage for adults is between 600-1000IU a day. Your physician can test your Vitamin D level with a simple blood test. When in doubt, talk to your physician or RD before taking a supplement. Vitamin D is extremely important for our overall health and should not be overlooked.
Steelhead Trout with Creamy Barley & Herb Salad
Steelhead and rainbow trout are the same species, but steelhead are anadromous, meaning that, like salmon, they migrate from the ocean to freshwater to spawn. Salmon and arctic char are a good substitute if you have trouble finding steelhead. The creamy barley the fish is served with has a texture similar to risotto, and toasting the grains before cooking gives the dish a nutty flavor. A knob of fresh horseradish is worth seeking out for this; it has a more nuanced flavor than jarred. Serve this healthy fish recipe with a glass of chenin blanc for an elegant and hearty dinner.
