10 Foods Highest In Vitamin D That You Should Include In Your Diet

10 Foods Highest In Vitamin D That You Should Include In Your Diet

Vitamin D – aka “the sunshine vitamin -” is important to our overall health and feelings of wellness. Most people connect vitamin D and sunshine because research has taught us that it is naturally produced in the skin when exposed to sunlight. Vitamin D is a fat-soluble vitamin in a family of compounds that includes vitamins D-1, D-2, and D-3. It can affect as many as 2,000 genes in the body.[1]

Vitamin D has several important functions. Perhaps the most vital are regulating the absorption of calcium and phosphorous, and facilitating normal immune system function. Getting a sufficient amount of vitamin D is important for normal growth and development of bones and teeth, as well as improved resistance against certain diseases.

The National Institutes of Health,[2] along with Health and Human Services, has determined the recommended daily allowance (RDA) for vitamin D is 600 IUs (15 mcg) for individuals between the ages of 13 and 70. The U.S. Food and Drug Administration (FDA) has set the recommended amount at 400 IUs which is slightly lower than other recommendations but still much higher than most people consume daily.

Vitamin D deficiency is a global epidemic.[3] An estimated 1 billion people do not have adequate vitamin D levels. And 64% of Americans do not get the sufficient amount of vitamin D to keep all of their tissues operating optimally.

Eating foods high in vitamin D is key in maintaining proper levels

Eating foods high in vitamin D is even more critical today than it was years ago. Our modern, indoor lifestyle limits the amount of vitamin D we receive. Even those who do spend lots of time outside still have insufficient levels of this important nutrient due to necessity of having to wear sunblock. Sunscreens do more than just block harmful UV rays it also limits the amount of vitamin that is absorbed by the skin. Because few foods have high amounts of this vitamin – and our limited exposure to the sun – it is critical to maintain a diet that is purposefully chock full of vitamin D rich foods.

10 Foods High in Vitamin D

1. Cod Liver Oil

This is the holy grail of vitamin D. One tablespoon contains 1,360 IUs,  which is more than twice the RDA. Cod liver oil is also a great anti-inflammatory agent and has properties that promote cardiovascular, hormonal, immune, reproductive and neurological health.

2. Portabello Mushrooms

Portabello mushrooms that have been exposed to ultraviolet light contain about 375 IUs per serving.[4] When grilled, that number jumps to 493 IUs per serving. Mushrooms are a great substitute for meat and are an excellent complement to many dishes.[5]

3. Oily Fish

Fatty fish, like tuna, trout, mackerel, and salmon, are rich in vitamin D. This group’s vitamin D content ranges from 760 IUs down to 100 IUs per serving. The oily fish ranking the highest are swordfish, salmon, trout and then mackerel. Besides being a vitamin D-rich food, fish rich in omega 3 fatty acids provide a plethora of health benefits – both physical and mental – and are considered a “superfood” among many nutrition experts.[6]

4. Fish Roe (Caviar)

Besides being fortified with vitamin D (484 IUs per serving), caviar[7] is a source of vitamins and minerals, including omega 3,[8] which helps to promote a healthy nervous, circulatory and immune system. One serving of this expensive delicacy also has an adult’s daily requirement of vitamin B12.[9] Other nutrients included are vitamins A, E, B6, iron, magnesium and selenium.

5. Orange Juice (fortified)

Orange fortified with vitamin D contains 137 IUs per eight ounce cup.[10] Fortified orange juice also comes packed with calcium and is an excellent source of vitamin C. And with OJ, a little goes a long way.

6. Fortified Breakfast Cereal

Instant oatmeal rates the highest in this category when it comes to vitamin D content. Most brands come in around 342 IUs per serving.[11] Traditional dry cereals are also great sources for packing in a large variety of vitamins and minerals in a single serving. When the cereal is combined with milk, the vitamin D content is further enhanced.

7. Dairy Products

Naturally, milk and other dairy products do not contain high amounts of vitamin D. Vitamin D is essential in the process the body undergoes to absorb calcium. It is for this reason, foods that naturally contain calcium, have been fortified with vitamin D. Dairy products such as milk, cheese, yogurt and margarine all have vitamin D added to enhance the potency of calcium.

8. Beef Liver

Beef liver is not only a pretty good source of vitamin D,[12] but since it is a storage organ for many important nutrients (vitamins A, D, E, K, B12 and folic acid), and minerals such as copper and iron, it naturally transfers those vitamins to us when we consume it. Liver is an “organ meat,” and generally speaking, organ meats are between 10 and 100 times higher in nutrients than corresponding muscle meats.

9. Eggs

Eggs are a convenient way to get vitamin D.[13] They’re popular in many breakfast, lunch, dinner, and dessert recipes. Vitamin D is contained in the yolk of an egg. One large egg contains around 44 IUs of the sunshine vitamin.

10. Dairy Alternatives

For those who are lactose intolerant or have sensitivities to dairy, getting the daily dose of vitamin D may prove to be a bit tricky. Thankfully, dairy alternatives such as soy and almond milk, dairy-free cheese, yogurt and many others have been fortified with calcium and vitamin D.

Maximizing the vitamin D in your food

How we prepare and consume food vastly effects its nutritional benefits and can either heighten or completely nullify certain nutrients.[14] When it comes to preparing foods to preserve their vitamin D content, its important to keep a few things in mind:

  1. Vitamin D is a very stable nutrient in foods. It will not be significantly damaged by most low-heat cooking techniques.
  2. Foods cooked in oil will lose some of their vitamin D content. Eggs, for example, when fried lose about 20% of their vitamin D, compared to only a 10% loss during the poaching process.
  3. The best way to preserve any food’s vitamin D content, based on information from various studies, is to avoid cooking food at higher heats and lengthy baking times.

Vitamin D is vitally important for proper functioning of our bodies and aids in preserving our mental health. A conscious effort must be made daily to ensure your diet includes the appropriate amount of the sunshine vitamin.

20 Time Management Tips to Super Boost Your Productivity

20 Time Management Tips to Super Boost Your Productivity

Are you usually punctual or late? Do you finish things within the time you stipulate? Do you hand in your reports/work on time? Are you able to accomplish what you want to do before deadlines? Are you a good time manager?

If your answer is “no” to any of the questions above, that means you’re not managing your time as well as you want. Here are 20 time management tips to help you manage time better:

1. Create a Daily Plan

Plan your day before it unfolds. Do it in the morning or even better, the night before you sleep. The plan gives you a good overview of how the day will pan out. That way, you don’t get caught off guard. Your job for the day is to stick to the plan as best as possible.

2. Peg a Time Limit to Each Task

Be clear that you need to finish X task by 10am, Y task by 3pm, and Z item by 5:30pm. This prevents your work from dragging on and eating into time reserved for other activities.

3. Use a Calendar

Having a calendar is the most fundamental step to managing your daily activities. If you use outlook or lotus notes, calendar come as part of your mailing software.

I use it. It’s even better if you can sync your calendar to your mobile phone and other hardwares you use – that way, you can access your schedule no matter where you are. Here’re the 10 Best Calendar Apps to Stay on Track .

Find out more tips about how to use calendar for better time management here: How to Use a Calendar to Create Time and Space

4. Use an Organizer

An organizer helps you to be on top of everything in your life. It’s your central tool to organize information, to-do lists, projects, and other miscellaneous items.

These Top 15 Time Management Apps and Tools can help you organize better, pick one that fits your needs.

5. Know Your Deadlines

When do you need to finish your tasks? Mark the deadlines out clearly in your calendar and organizer so you know when you need to finish them.

But make sure you don’t make these 10 Common Mistakes When Setting Deadlines.

6. Learn to Say “No”

Don’t take on more than you can handle. For the distractions that come in when you’re doing other things, give a firm no. Or defer it to a later period.

Leo Babauta, the founder of Zen Habits has some great insights on how to say no: The Gentle Art of Saying No

7. Target to Be Early

When you target to be on time, you’ll either be on time or late. Most of the times you’ll be late. However, if you target to be early, you’ll most likely be on time.

For appointments, strive to be early. For your deadlines, submit them earlier than required.

Learn from these tips about how to prepare yourself to be early, instead of just in time.

8. Time Box Your Activities

This means restricting your work to X amount of time. Why time boxing is good for you? Here’re 10 reasons why you should start time-boxing.

9. Have a Clock Visibly Placed Before You

Sometimes we are so engrossed in our work that we lose track of time. Having a huge clock in front of you will keep you aware of the time at the moment.

10. Set Reminders 15 Minutes Before

Most calendars have a reminder function. If you have an important meeting to attend, set that alarm 15 minutes before.

You can learn more about how reminders help you remember everything in this article: The Importance of Reminders (And How to Make a Reminder That Works)

11. Focus

Are you multi-tasking so much that you’re just not getting anything done? If so, focus on just one key task at one time. Multitasking is bad for you.

Close off all the applications you aren’t using. Close off the tabs in your browser that are taking away your attention. Focus solely on what you’re doing. You’ll be more efficient that way.

Lifehack’s CEO has written a definitive guide on how to focus, learn the tips: How to Focus and Maximize Your Productivity (the Definitive Guide)

12. Block out Distractions

What’s distracting you in your work? Instant messages? Phone ringing? Text messages popping in?

I hardly ever use chat nowadays. The only times when I log on is when I’m not intending to do any work. Otherwise it gets very distracting.

When I’m doing important work, I also switch off my phone. Calls during this time are recorded and I contact them afterward if it’s something important. This helps me concentrate better.

13. Track Your Time Spent

When you start to track your time, you’re more aware of how you spend your time. For example, you can set a simple countdown timer to make sure that you finish a task within a period of time, say 30 minutes or 1 hour. The time pressure can push you to stay focused and work more efficiently.

You can find more time tracking apps here and pick one that works for you.

14. Don’t Fuss About Unimportant Details

You’re never get everything done in exactly the way you want. Trying to do so is being ineffective.

Trying to be perfect does you more harm than good, learn here about how perfectionism kills your productivity and how to ditch the perfectionism mindset.

15. Prioritize

Since you can’t do everything, learn to prioritize the important and let go of the rest.

Apply the 80/20 principle which is a key principle in prioritization. You can also take up this technique to prioritize everything on your plate: How to Prioritize Right in 10 Minutes and Work 10X Faster

16. Delegate

If there are things that can be better done by others or things that are not so important, consider delegating. This takes a load off and you can focus on the important tasks.

When you delegate some of your work, you free up your time and achieve more. Learn about how to effectively delegate works in this guide: How to Delegate Work (the Definitive Guide for Successful Leaders)

17. Batch Similar Tasks Together

For related work, batch them together.

For example, my work can be categorized into these core groups:

  1. writing (articles, my upcoming book)
  2. coaching
  3. workshop development
  4. business development
  5. administrative

I batch all the related tasks together so there’s synergy. If I need to make calls, I allocate a time slot to make all my calls. It really streamlines the process.

18. Eliminate Your Time Wasters

What takes your time away your work? Facebook? Twitter? Email checking? Stop checking them so often.

One thing you can do is make it hard to check them – remove them from your browser quick links / bookmarks and stuff them in a hard to access bookmarks folder. Replace your browser bookmarks with important work-related sites.

While you’ll still checking FB/Twitter no doubt, you’ll find it’s a lower frequency than before.

19. Cut off When You Need To

The number one reason why things overrun is because you don’t cut off when you have to.

Don’t be afraid to intercept in meetings or draw a line to cut-off. Otherwise, there’s never going to be an end and you’ll just eat into the time for later.

20. Leave Buffer Time In-Between

Don’t pack everything closely together. Leave a 5-10 minute buffer time in between each tasks. This helps you wrap up the previous task and start off on the next one.
