What is Vitamin D?

Vitamin D is a fat-soluble vitamin necessary for the body. It helps in increased absorption of calcium, magnesium, and phosphate. It also has several other biological impacts. The most significant chemicals of Vitamin D are Vitamin D3 (cholecalciferol) and Vitamin D2 (ergocalciferol).

Role of Vitamin D

Vitamin D can help prevent infections, lessen inflammation, and slow down the formation of cancerous cells. Vitamin D receptors are present in a large number of bodily organs and tissues, suggesting that this vitamin performs vital tasks in addition to maintaining bone health.

The Recommended Dietary Allowance for Vitamin D relates to the daily dose required to maintain strong bones and regular calcium metabolism.

UL: The highest daily consumption unlikely to negatively impact health is known as the Tolerable Upper Intake Level (UL). The UL for Vitamin D is 4,000 IU (100 mcg) for kids aged nine and older.
RDA: The Recommended Daily Allowance for adults aged 19 and older is 600 IU (15 mcg), and 800 IU (20 mcg) for those over 70 years of age.

Vitamin D Deficiency

The human body depends on vitamin D, a fat-soluble vitamin, for several physiological processes. It is best known for its role in promoting healthy bones and avoiding diseases like rickets in children and osteomalacia in adults.

Vitamin D is often called the "sunshine vitamin" because our skin can make it when it's exposed to sunlight. When UltraViolet rays from the sun touch our skin, a substance in our skin cells called 7-dehydrocholesterol turns into a kind of pre-vitamin D. This pre-vitamin D travels through our bloodstream to our liver, where it gets converted to 25-hydroxyvitamin D, or 25(OH)D for short. Thereafter 25(OH)D travels to the kidneys, where it undergoes another modification to become 1,25-dihydroxyvitamin D, also known as calcitriol — the active form of vitamin D.

One of Vitamin D's most well-known functions is aiding the body's ability to absorb calcium and phosphate from the intestines. This helps in preserving healthy blood levels of these minerals, which are essential for bone health. Vitamin D is necessary for the process of bone mineralization, which makes bones more dense and strong. Together with calcium and other minerals, it helps to develop and maintain strong bone tissue.

According to some research, having adequate amounts of vitamin D may lower your chance of developing chronic illnesses like diabetes, heart disease, and some types of cancer. However, additional investigation is required to show clear causation.

Vitamin D deficiency is a global health concern, especially in regions with limited sunlight exposure or for individuals with certain dietary restrictions. Following are some telltale symptoms of Vitamin D deficiency:

Joint pains along with weakness in muscles
A weaker immune system leads to frequent infections
Fatigue and tiredness, during the day, even after a good night's sleep
Cuts and bruises take longer than usual to heal
Increased risk of fractures due to weaker bones
Thinning hair or increased hair loss
Mood changes, especially during the darker months

In such cases, supplementation may be recommended under the guidance of a healthcare professional. However, although vitamin D is essential for health, taking too much of it can be hazardous, leading to toxicity. It's important to note that Vitamin D toxicity is rare and typically occurs from very high doses of supplements, rather than from dietary sources or sun exposure. The following are the symptoms of Vitamin D toxicity:

Nausea and vomiting
Weakness and fatigue
Loss of appetite
Excessive thirst and urination
Kidney dysfunction includes changes in urination patterns, blood in urine, or even kidney stones.
Confusion and disorientation
Elevated blood Calcium levels (Hypercalcemia)
Irregular heartbeat and high blood pressure

The Recommended Dietary Allowance (RDA) for vitamin D gives healthy individuals the daily dose required to maintain strong bones and consistent calcium metabolism. It is based on minimal sun exposure values. For adults aged 19 and older, the recommended daily allowance is 600 IU (15 mcg) for men and women, and 800 IU (20 mcg) for those over 70 years of age.

The maximum daily consumption that is unlikely to have a negative impact on health is known as the Tolerable Upper Consumption Level (UL). For adults and kids aged 9 and older, the UL for vitamin D is 4,000 IU (100 mcg).

List of the top food items high in Vitamin D

Although sunlight/sun rays exposure can help your body produce Vitamin D, it is not always reliable because of weather changes. To ensure adequate Vitamin D levels in your body, try to include these items in your daily diet, along with a lot of fruits and vegetables. (Note: Please consult a doctor before making dietary changes.)

Food item	Explanation
Fortified Orange Juice	As it is fortified with Vitamin D and calcium, lactose intolerant people may find this item a trustworthy supply of nutrition. One cup of enriched orange juice has 100 IU of Vitamin D.
Mushrooms	Mushrooms, like humans, can synthesise Vitamin D in the presence of sunlight. They are high in Vitamin D2 and contain 2300 IU per 100gm. On the other hand, mushrooms that are grown commercially have minimal Vitamin D2. Certain types are treated with UV light, making them a good source of Vitamin D. Vitamin D2 levels in these mushrooms range from 130 to 450 IU.
Canned Tuna	Canned tuna has 268IU of Vitamin D, making it an excellent source. It's also a less expensive choice than buying fresh fish. Eating canned tuna can also boost your niacin and vitamin K levels. However, because it contains poisonous methylmercury, over-ingestion of this dietary item might result in significant health problems. Fortified cereal. Half a cup of cereal contains 54-136 IU of Vitamin D, making it a good source.
Herrings	This is a popular fish, whether canned, smoked, pickled, or raw. Per 100gm serving, it contains 216 IU of Vitamin D. Pickled herring also has 112 IU of Vitamin D and salt, both of which are necessary for the human body.
Salmon	This fatty fish is high in Vitamin D. A single serving of 100gm Atlantic salmon has 526 IU of Vitamin D, according to the United States Department of Agriculture (USDA) Food Composition Database. Wild salmon contains more Vitamin D than farmed salmon. A 100g serving of wild salmon has 988 IU of Vitamin D, whereas farmed salmon contains only 25% of the recommended dosage.
Cow's milk (fortified)	This is a popular food in India that contains calcium, phosphorus, and riboflavin. It is an excellent source of Vitamin D, with 115-130 IU per cup. This can also be a good Vitamin D rich food for a 1 year old baby.
Cod Liver Oil	Instead of eating fish, you can take this as a supplement. It is nutrient-dense and includes 448 IU of Vitamin D per teaspoon. Children who are Vitamin-D-deficient might consider taking this. It is also high in Vitamin A and Omega-3 Fatty Acids, which your body requires. However, you should avoid taking too much cod liver oil because an increase in Vitamin A levels in your body might be dangerous. This can also be a Vitamin D rich food for hair growth.
Egg Yolks	Consuming eggs provides 37 IU of this vitamin. However, the Vitamin D content of eggs is determined by sun exposure and the Vitamin D level of chicken feed. Eggs from chickens grown on pasture and exposed to sunlight are three to four times richer in Vitamin D. These eggs have 6000 IU of Vitamin D.
Sardines	Sardines are an excellent source of this vitamin. It has 177 IU of Vitamin D in it. Vitamin D foods to add to your diet include fatty fish such as halibut and mackerel.

Vitamin D deficiency

A shortage of Vitamin D in the diet, poor absorption, or a need for higher quantities due to a metabolic condition can all lead to Vitamin D deficiency. A deficiency may occur if a person does not consume enough Vitamin D and does not spend enough time in the sun.

Vitamin D deficiency can lead to the following conditions.

Cancer: Studies have shown that Vitamin D helps prevent the growth of tumours and reduce their progression, including Breast, Ovary, Colon, Prostate Cancer, and Brain Tumours.
Type 2 Diabetes: The conditions that result in Type 2 diabetes (T2DM), such as impaired pancreatic beta cell function, insulin resistance, and inflammation, may severely impact Vitamin D deficiency. Higher Vitamin D blood levels have been linked to decreased incidence of type 2 diabetes.
Cold: Low Vitamin D levels in adults are associated with an increased likelihood of recent upper respiratory tract infections, colds, and coughs.
Rickets: Rickets is a disease that causes bone abnormalities in infants and young children due to the failure of bone tissue to solidify. Low levels of Vitamin D can lead to this medical condition.
Osteomalacia : Adults with osteomalacia have weak, brittle bones that can be strengthened with Vitamin D dietary supplements. This differs from Osteoporosis, which causes bones to become porous and brittle, and is irreversible.

DID YOU KNOW?

Cancer Fighter: Vitamin D can reduce cancer cell growth, help control infections and reduce inflammation.
Not a Vitamin: Vitamin D is actually a hormone rather than a vitamin; it is required to absorb calcium and phosphate from the gut into the bloodstream

Summary

The sun helps the body produce Vitamin D, it may be a complex chemical reaction but getting about 20 minutes of some good sunlight everyday shouldn't be too hard. This particular vitamin plays an important role in maintaining bone health and immunity. Make sure you walk into the sunlight, often.
