These days, many people are simply not getting enough sunlight. They are staying indoors and spending hours in front of the television or the internet, while other areas are naturally unable to receive sufficient sunlight due to changes in weather and climate patterns depending on where they live.
The Paleo diet recommends that you get a good amount of natural sunlight for good health. People who do not receive enough Vitamin D suffer from a number of health problems. Lack of sunshine can lead to deficiencies that can cause a person to have hormonal problems including episodes of depression. The body that does not have sufficient Vitamin D will also suffer from weak bones, and can be prone to bone fractures. Insufficient Vitamin D can also lead to a weakening of the immune system, as well as imbalance in insulin, calcium and phosphorus levels.
Why do you need to get Vitamin D from sunlight?
There are a number of Vitamin D supplements being offered, but it does not mean that they can be readily absorbed by the body. For this reason, there is a need to get direct vitamin D from sunlight. The sun rays will still provide the recommended daily allowance of vitamin D that most supplements are not able to provide.
By simply lounging or playing in sunlight for about 30 minutes, a person can get 600 to 800 international units of IU based on their age. Those on the Paleo diet are being encouraged to go outside and get some much needed sunshine every day in order to meet the 2,000 IU of Vitamin D needed every day in order to maintain recommended vitamin D levels.
How does the body convert sunlight into Vitamin D?
Once the body is exposed to the sun’s ultraviolet rays, it will undergo a chemical reaction. The body will start converting the aprohormone in the skin into vitamin D. This process will involve a cholesterol called 7-dehydrocholesterol which is naturally occurring in the skin and will absorb the UVB radiation.
What are other sources of Vitamin D?
Sunlight is still the best source, but there are some who have to work late at night and then have to sleep during the daytime. Since they will not be able to get sunshine, they can eat certain foods like egg yolks in order to receive at least 20 IU of Vitamin D. There are also cereals, juices and other vitamin D-fortified foods that can be a source of Vitamin D, including that of milk.
How much vitamin D does the body need?
The body should get 90% of vitamin in D from daily exposure. If this is not met the body can suffer from a number of immune system problems. Daily sun exposure is crucial, and it is highly recommended for people to stay in the sun for 15 to 30 minutes in order to meet vitamin D requirements in order to avoid health risks, especially if they are on the Paleo diet.
