Vitamin D Deficiency? Top 20 Vitamin D Foods You Have to Try Before Supplements
Vitamin D deficiency is a growing problem in the US and other northern parts of the world where people are less exposed to the sun all year round. It is even estimated that almost 90% of the adult population in the US is somewhat deficient in vitamin D. People living in the US with darker skin, such as the Hispanics, Asians, and Black, have a higher chance of being vitamin D deficient. Those who are overweight and obese are also at risk of vitamin D deficiency. It is also very alarming that this vitamin D deficiency can cause severe illnesses and diseases such as hypertension, cancer, autoimmune diseases, and various infectious diseases. This is the reason why a lot of doctors today are prescribing vitamin D supplements to their patients. Health experts are also recommending vitamin D foods that can help fight the symptoms of vitamin D deficiency.
What is Vitamin D?
Vitamin D is different from other vitamins because the body can create most of the vitamin D on its own, rather than relying on food sources. Vitamin D is a fat-soluble vitamin that is stored in the liver and fatty tissues. The increased body fat can absorb the vitamin D and keep it from being used within your body. The human body is designed to convert the sunshine into chemicals that can be used by the body. The cholesterol in your skin converts provitamin D and makes it into a usable vitamin D3 or provitamin D. When vitamin D is inside the body, it becomes a hormone, particularly a secosteroid hormone. Vitamin D is a precursor to a steroid hormone, so it has an effect on the body’s skeletal structure, immunity, blood pressure, brain function, mood, and ability to prevent cancer.
There are actually two types of vitamin D, the vitamin D2, and D3. The type of vitamin D that the body makes is vitamin D3. Vitamin D3 can also come from animal-derived products which are more beneficial and easy to absorb. It is believed that vitamin D3 can be converted up to 500 times faster than vitamin D2, and D3 is four times more effective than D2. Unfortunately, many vitamin D supplements and vitamin D fortified foods contain vitamin D2, which cannot be absorbed or converted by the body.
The Importance of Vitamin D
Do you know why vitamin D is vital for your overall health? Here are some of the top reasons why you should need the sunshine every morning and eat more vitamin D foods.
- It supports and regulates your immune system
- Maintains a healthy body weight
- Maintains normal brain function as you grow older
- Reduce the risk of developing multiple sclerosis
- Reduce and minimize the frequency of asthma symptoms
- Reduce the risk of developing rheumatoid arthritis in women
Symptoms of Vitamin D Deficiency
Your usual source of vitamin D is from sunlight exposure. When the UV rays hit the skin, your skin begins to make vitamin D. This means that majority of the people experiencing symptoms of vitamin D deficiency is caused by their indoor lifestyle and lack of sun exposure.
Most often, it is difficult to identify the common symptoms because they are vague, such as tiredness, and aches and pains. Here are the symptoms that you may have to look out for when you think that you are not getting enough sunshine and vitamin D.
- Pain in your bones
- Overall weakness and tiredness
- Getting frequent infections
- Difficulty in moving around
It is important to know that some people may not experience these symptoms even if they are already vitamin D deficient. If Vitamin D deficiency is not treated early, it can also lead to serious chronic diseases such as:
- Cold & flu
- Alzheimer’s Disease
- Diabetes 1 and 2
- Heart disease
- Eczema and Psoriasis
- Hearing loss
- Cystic Fibrosis
- Muscle Pain
- Macular degeneration
- A migraine
- Inflammatory Bowel Disease
- Rheumatoid Arthritis
As you can see, there are so many diseases that are associated with vitamin D deficiency. The only way to know that you are vitamin D deficient is to consult your doctor and find out your vitamin D level. Here are the numbers to check when doing your blood test for your vitamin D level.
If the result shows 50 and above, it means you have a good level of vitamin D. If the result shows 30 to 50, you will need to take a vitamin D supplement and you should have more sun exposure. You will also need to add more vitamin D foods to your diet. If the result shows below 30, then you are very deficient and you definitely need to improve your vitamin D level immediately
Health Benefits of Vitamin D
It is important to get your morning dose of sunshine at least twice a week. Don’t overdo your sun exposure and limit the time to only 15 minutes in the morning. If you are living in a place where there is not enough sunlight, you can increase your intake of vitamin D foods and high-quality vitamin D supplements. Here are some of the health benefits that you can get when you take vitamin D regularly.
Improve Bone Health
You need vitamin D to improve the calcium absorption into your bones. The vitamin D in your body is converted to Calcitrol, which then works with the parathyroid hormone to maintain your calcium levels. Vitamin D deficiency can result in the softening of the bones called osteomalacia, or lead to bone abnormality called rickets. It can also increase the risk of developing osteoporosis and frequent bone fractures. Here are other benefits of vitamin D for your bone health:
- Slows down the aging of the skeletal structure
- Reduce the rate of fractures for old adults over 65
- Improved strength
- Strengthens bones and properly mineralize bone density
Manage Blood Sugar Levels and Prevent Diabetes
Vitamin D can prevent diabetes because it can help maintain insulin secretion. Diabetes results from inadequate insulin secretion following increases in insulin resistance. There are several studies that support vitamin D as being effective in preventing and managing both diabetes type 1 and 2.
Lowers the Risk of Heart Disease
Several studies have suggested that vitamin D deficiency is closely linked to cardiovascular disease. Since vitamin D is involved in regulating blood pressure, inflammation, and cholesterol levels, there is a very strong possibility that vitamin D deficiency can lead to heart diseases. People who are vitamin D deficient are more likely to suffer from coronary heart disease and other related health problems.
Better Weight Management
People who are vitamin D deficient are mostly overweight or suffer from obesity. A study has indicated that women who have higher levels of vitamin D were capable of losing more weight than the others who have lower vitamin D levels. If you are having difficulty in losing your weight, you can have your vitamin D level checked.
Lowers the Risk of Cancer
Several studies have suggested that healthy levels of vitamin D can reduce the risk of cancer, especially colon and breast cancer. The reason behind this is probably because vitamin D has a huge role in the cell life cycle and its ability to block excess estrogen.
Enhance the Immune System
It’s been proven that vitamin D can prevent prolonged or excessive inflammatory responses. Inflammation is the usual cause of many chronic diseases and autoimmune disorders such as rheumatoid arthritis, multiple sclerosis, irritable bowel syndrome, and other digestive problems. Vitamin D also helps in replicating healthy cells and it may have a role in preventing the development of colds and flu and other serious health problems.
Vitamin D acts as a hormone in your body that can affect brain function. Deficiency in vitamin D has a strong link towards increased mood disorder, which includes depression, seasonal depression, insomnia, and anxiety.
Sharpens Concentration, Memory, and Learning
Studies have shown that vitamin D has a strong link in the brain’s ability to concentrate, retain information, and make good decisions. People with lower levels of vitamin D have been found to perform poorly in exams and have difficulty in completing tasks that require concentration and focus.
