Food with Highest Vitamin D: Top 10 Superfoods to Add to Your Diet

Sunlight is the primary source of Vitamin D. This is one of the only concepts most people have about Vitamin D. However, did you know that, despite vitamin D being abundantly available across the globe, it ranks as one of the most common vitamin deficiencies in the Indian population? Yes, the country that lives and breathes outdoor life suffers severely from vitamin D deficiency across all regions of the country and all age groups.

Even though covered clothing, indoor lifestyle habits, and high pollution levels contribute to the prevalence of vitamin D deficiency in Indians, one factor ranks above all: a diet that does not contain vitamin D-rich food. So, to help you address this deficiency and live a healthier and better life, here is a detailed look at the top 10 superfoods to add to your diet.

Quick Overview: Food with Highest Vitamin D

The Indian Council of Medical Research (ICMR) recommends a daily intake of 600 IU of vitamin D for Indian adults. The list below gives you a quick overview of the vitamin D amount per serving of each food item detailed in this blog.

What is Vitamin D and Why Is It important?

Vitamin D is a nutrient that’s used by your body along with calcium to support bone health. The way it works is, your body can absorb calcium only when there’s sufficient vitamin D in your system. As calcium is a major part of bones, vitamin D deficiency indirectly leads to bone health problems. Vitamin D also helps your immune system health and keeps your muscles and brain functioning optimally.

Here are the top benefits of Vitamin D for your body:

• Helps reduce inflammation in the body
• Supports calcium and phosphorus absorption
• Improves muscle strength
• Can improve mood and has potential benefits for depression
• Supports heart health

Vitamin D Deficiency in India

Vitamin D deficiency is common in India. It is, in fact, one of the most common and overlooked vitamin deficiencies in the country. There are studies that suggest that up to 70% of the population in India across different age groups, lifestyles, and regions are affected by this deficiency. This is concerning because vitamin D plays a crucial role in managing your overall health. Here are the reasons why vitamin D deficiency is so common in India.

• Low Sun Exposure: Being located in the torrid zone of the earth, India experiences very high sun exposure. This also means extreme heat and humidity in most parts of the country. This has created a culture of limiting sun exposure during most parts of the year due to the harsh sunlight, which causes conditions like sun strokes that can be fatal.
• High Pollution Levels: India has very high air pollution across the country, which blocks the UVB rays that are essential for vitamin D production in the skin. Additionally, using sun protection heavily to prevent the higher risk of skin cancer also blocks UVB rays from entering your body.
• Dark Skin Pigmentation: Indians have darker skin pigmentation. This leads to difficulty producing vitamin D efficiently inside the body. The cause for this difficulty is the high level of melanin in the skin of Indians. The thing that protects you from skin cancer causes you to have poor bone health.
• Dietary Gaps: The typical Indian diet does not have adequate amounts of vitamin D-rich food, such as fatty fish and fortified foods.

Top 10 Vitamin D Rich Foods to Add to Your Diet

1. Salmon Fish

Salmon is a very good source of vitamin D. It is important to note that salmon is not widely available across India. So, if you have access to salmon, you should consider adding it to your diet. 100 grams of salmon contains 570 IU of vitamin D; it can fulfill over 90% of your daily vitamin D requirement. It is convenient because you can easily add salmon to your diet at any part of your day, and it can help you maintain your diet and health.

• Vitamin D Amount: 570 IU approximately in every 100 grams of cooked fish
• How much of your daily needs? Covers close to 95% of your daily vitamin D requirement

2. Cod Liver Oil

Cod liver oil is basically a very rich source of vitamin D. If you can find raw cod liver oil, you can add it to your diet, but in most cases, it is not readily available. So, cod liver oil is added to your diet as a supplement. Just one tablespoon, which corresponds to 15 grams of cod liver oil, contains 1,360 IU of vitamin D. This is 225% of your daily vitamin D requirements as per ICMR guidelines. So, as you can imagine, if you have a vitamin D deficiency, this is the best way to meet your daily requirements and more. However, please note that it is not advisable that you consume over double the daily required amount of vitamin D unless specifically guided by a medical professional.

• Vitamin D Amount: 1,360 IU in approximately one tablespoon of cod liver oil
• How much of your daily needs? 225% of your daily vitamin D requirements in just one tablespoon.

3. UV-Exposed Mushrooms

Vitamin D is not generally available in vegetarian sources. This is actually a big reason why a lot of Indians have a vitamin D deficiency, because many Indians are vegetarians. So, if you are a vegetarian, you can consider adding UV-exposed mushrooms to your diet. They are a vegetarian source of vitamin D, and you can even boost their vitamin D content by exposing them to the sun before cooking them.

• Vitamin D Amount: 130 to 400 IU per 100 to 120 grams of mushrooms (half cup)
• How much of your daily needs? 20 to 65% of your daily required vitamin D intake

4. Rainbow Trout Fish

Rainbow trout is another strong source of vitamin D and functions in the same way salmon does. It can be easily added to your diet at any time of the day. However, it should be noted that Rainbow Trout may also have limited availability in some parts of the country, so you should add it to your diet if it is available where you’re located in India. 100 grams of cooked rainbow trout contains 645 IU of vitamin D. Rainbow trout is more vitamin D-rich than salmon.

• Vitamin D Amount: 645 IU in every 100 grams of cooked fish
• How much of your daily needs? 108% of your daily required vitamin D intake

5. Cheddar Cheese

Cheddar cheese is a good source of vitamin D. Its availability in India is limited to urban centres, so if it is available where you are located, you can consider adding it to your diet. Cheddar cheese still contains less vitamin D compared to a lot of other options mentioned on this list. Per 30 grams of cheddar cheese, there’s only 34 IU of vitamin D, which accounts for around 5% of your daily needs.

• Vitamin D Amount: 34 IU of vitamin D per 30 grams of cheddar cheese
• How much of your daily needs? Around 5% of your daily vitamin D intake requirements

6. Sardines Fish

Sardines are readily available in India in the coastal regions across the country. It is a rich source of vitamin D and among the few non-fortified natural vitamin D sources. The availability of sardines is what makes them a popular source of vitamin D in people’s diet. On average, two sardines contain up to 178 IU of vitamin D, which accounts for around 30% of your daily intake requirements.

• Vitamin D Amount: 178 IU for two sardines consumed
• How much of your daily needs? 30% of your daily required vitamin D intake

7. Tuna Fish

Tuna is not generally available in fresh form in India. So, if you want to add tuna to your diet as a vitamin D source, your best bet is to depend on canned tuna that’s available in supermarkets and through online retailers. In India, canned food is not a big part of the diet and is not even taken well as an ingredient in home-cooked meals, so you don’t have to consider tuna as a vitamin D source if you don’t want to. Anyway, 100 grams of cooked tuna contains only 154 IU of vitamin D. This is significantly lower than that of trout, sardines, and salmon.

• Vitamin D Amount: 154 IU per 100 grams of cooked fish
• How much of your daily needs? 25% of your daily required vitamin D intake

8. Fortified Orange Juice

Orange juice is a popular fruit juice option that’s now readily available across the country. It is also easy to add to your diet either as a snack or more traditionally as a part of your breakfast. Although having orange juice after brushing your teeth in the morning would, in almost all cases, make the orange juice taste bitter. So, that becomes quite a difficult experience. Nonetheless, orange juice contains 100 IU of vitamin D per cup.

• Vitamin D Amount: 100 IU of vitamin D per cup (237 grams)
• How much of your daily needs? 15 to 17% of the daily required vitamin D intake

9. Fortified Milk

Again, this is a vegetarian source and abundantly available in India to help you meet your daily vitamin D requirements. However, do remember that lactose intolerance is also one of the most common allergies in India. So, meeting your daily vitamin D requirements with fortified milk may have other negative health impacts for you if you have lactose intolerance. Also, fortified milk contains up to 120 IU of vitamin D per cup of milk, so you’ll need to consume multiple cups of milk per day to fulfill your daily requirements for vitamin D only through milk.

• Vitamin D Amount: 120 IU of vitamin D for one cup of milk (237 grams)
• How much of your daily needs? 20% of your daily required vitamin D intake

10. Egg Yolk

There are people in the country who do not consider eggs to be non-vegetarian items. So, for them, egg yolk can be a good source of vitamin D. Eggs are also very versatile and can be added to your diet very easily. It is also abundantly available across the country. One egg yolk contains 37 IU of vitamin D. While that’s not a lot, since eggs can be consumed in multiples, it can even independently make up for a decent part of your daily vitamin D intake.

• Vitamin D Amount: 37 IU of vitamin D in one egg
• How much of your daily needs? If you’re consuming one egg a day, it covers around 6% of your daily vitamin D intake requirements

Tips For Improving Vitamin D Intake From Your Diet

You must understand and follow a balanced diet. The key is not to try to fulfill all your daily vitamin D intake requirements using just one food source. Yes, it is possible to do that, but that is not the best way to look at it. Instead of having a piece of salmon, sardine, or rainbow trout every day, you can also consider the following:

• Mixing and matching: Once in a while, preparing an egg dish with cheese and mushrooms can also help you get some vitamin D intake. It helps you create a realistic plan while not limiting your diet to just one item.
• Considering supplements: You should only consider supplements if they have been recommended by your doctor. This helps you ensure the supplement is actually helping you meet your daily intake requirements without hampering your health otherwise. And in some cases, when you can’t source the ideal vitamin D food sources for your diet, the supplement can help you meet your daily requirements. This helps you stay on track with your daily requirements without having to give up on your diet.

Benefits of Vitamin D in the Human Body

Vitamin D possesses a distinct quality among Vitamins because our bodies can produce it when our skin comes into contact with Sunlight.  Furthermore, it is also attainable through specific vitamin d fruits and vegetables. Here we will be highlighting the benefits of vitamin D in the Human body, supported by scientific research:

What Does Vitamin D Deficiency Lead to in the Body?

When the body lacks Vitamin D, it can lead to various health problems because of the vital role that vitamin D plays in preserving overall health and welfare. While the human body has the ability to produce vitamin D, there are certain individuals who may be more susceptible to experiencing a lack of this essential nutrient. There are several factors that can contribute to this potential deficiency, such as: 

• Brittle and Weak bones: Vitamin D plays a vital role in the absorption of calcium in the intestines, which is necessary for preserving robust and nourished bones. Insufficient levels of vitamin D can result in a condition known as osteomalacia in grown-ups or rickets in kids, where bones become weak, brittle, and susceptible to fractures. Incorporating vitamin d fruits and vegetables will help in strengthening weak bones. 
• Increased risk of osteoporosis: Vitamin D insufficiency may heighten the risk of Osteoporosis, a medical condition characterized by bone density and increased susceptibility to Fractures. Insufficient vitamin D levels hinder the body's capacity to absorb calcium from the diet, ultimately resulting in progressively feeble bones. 
• Weaken Muscles:  Vitamin D plays a vital role in the functioning of our muscles, and lack of it can result in weakened muscles and potentially even muscle pain or back pain. Consequently, this can have an impact on our ability to move and perform physical tasks, making day-to-day activities more challenging. 
• Weakening immune system: Vitamin D has a crucial role in regulating the immune system. Insufficient levels can hinder immune functionality, making the body more susceptible to infections like respiratory illnesses, influenza, and autoimmune disorders. It is believed that including vitamin d fruits and vegetables will  be beneficial for individuals, to enhance immune functions. 
• Increased risk of chronic diseases: Research has revealed a correlation between a lack of vitamin D and an increased risk of developing various chronic diseases. These conditions encompass Cardiovascular Disease, diabetes, certain forms of cancers (like those affecting the colon, prostate, and breast), as well as autoimmune disorders such as multiple sclerosis.
