Basking in the glory of
the
Sunshine Vitamin
It’s nice to
have a reality check once in a while, especially when it comes to one’s health.
My client, Nafisa, 36, had one a few weeks ago. It started with muscle spasms
around the waist and ended in a nasty catch in her lower back. It’s still
healing and she has to be very careful.
Normally, she
would have ignored it after taking a few painkillers, anti-inflammatory and
physiotherapy sessions. But when her doctor asked her to get an x-ray of the
lateral view of her lower back, she was alerted.
The x-ray revealed
that her D3 and calcium levels were low. Although, she is always very
particular about her diet, she realized that she hadn’t been regular with her calcium
supplements over the past year. Now, she is on weekly D3 supplements and daily calcium tablets. This experience has
taught her that one cannot take one’s body for granted.
Listen to your body
Many a times,
we ignore pain and don’t listen to our bodies. Our body is constantly giving
out signals. For instance, Shweta’s muscle spasms must have been the body
signaling a calcium and vitamin D deficiency.
The other
day, I bumped into one of my old acquaintances in the gym. She looked pale and
in pain. She told me that she has had back pain for the past eight years. The
low D3 and calcium levels were taken care of with supplements. She has also
been through physiotherapy sessions but admitted that she hasn’t been regular
with her physio exercises. With 40% pain still there, I advised her to visit
her physio again and then continue with those exercises besides her regular
workouts.
I have also
come across many patients in the clinic who come for diet consultation with low
calcium and D3 levels. A couple of my other clients too are guilty of the same.
What is it about these two elements, which are abundant in food, especially
calcium, but still deficient in humans? Vitamin D is made by our body in
sunlight but why are we still lacking it?
Another
common deficient vitamin is B12, especially in vegetarians. Surprising,
considering we make it in our intestine! And the daily requirement is also not
much, just 2.4 mcg.
Wake Up
The idea of
blogging this is - I seriously want everyone, particularly women over 30, to
keep a tab on their diet, particularly vitamin D and calcium intake. If you get
a catch regularly, have muscle spasms and pain; get yourselves checked to rule
out the deficiency.
When we talk
about bone building, it’s always calcium and vitamin D that hog the limelight.
There are other contributing minerals like phosphorus, magnesium, zinc, copper,
manganese, boron, silicon and vitamins C, K, B-complex (B6, B9, and B12) at
play.
I will be
starting a series featuring the above mentioned elements for strengthening
bones. The first is vitamin D, the sunshine vitamin.
Vitamin D (Cholecalciferol)
-
The
sunshine vitamin, our body can produce in sunlight
-
Optimal
time to get sunlight is 10 am - 4 pm when UV light which stimulates vitamin D production
is at its greatest intensity
-
Vitamin
D has to be taken with calcium for the body to utilize it efficiently
-
50
per cent of adults and children worldwide are vitamin D deficient
-
Our
body needs vitamin D to absorb calcium from food to make bones and help us
relax
-
It
also helps to absorb phosphorus
-
Children
need more for their growing bones and deficiency causes rickets
-
In
adults, the deficiency manifests as osteoporosis
-
Vitamin
D is a fat-soluble vitamin, so your body can store extra amounts of the vitamin
-
Reserves
of vitamin D are found in the liver, skin, brain and bones, for future use
Recommended Daily
Intake (RDI)
19 -50 years: 5 mcg or 200 IU per day
51-70 years: 10 mcg or 400 IU per day
70+: 15 mcg or 600 IU per day
Although the body can make
vitamin D, there are many reasons for its deficiency:
-
Inability
to convert vitamin D to D3, its active form. One of the factors is age
-
Darker
skin pigments and sunscreen use can significantly decrease the body’s ability
to absorb the UV rays required to produce vitamin D
-
A
sunscreen with SPF 30 can reduce the body's ability to synthesize the vitamin
by 95 per cent
-
The
skin also has to be directly exposed to the sunlight, not covered by clothing,
in order to start vitamin D production.
-
Even
the angle at which sunrays hit the earth can affect absorption
-
People
who live in northern latitudes or areas of high pollution, work at night and
stay home during the day or are homebound should consume extra vitamin D from
food sources or supplements
-
Infants
who are exclusively breastfed are also at high risk of vitamin D deficiency,
especially if they are dark-skinned or have minimal sun exposure
-
Sources
-
Three
ways to get Vitamin D: food, sunlight and supplements
-
If
you are not getting enough sunlight, you need to take supplements. But it is
best to obtain any vitamin or mineral through natural sources first
-
It
is not the individual vitamin or mineral alone that make certain foods an
important part of our diet, but the synergy of that food’s nutrients working
together and allowing for greater absorption
-
Take
this vitamin supplement either with or after your meals in milk
-
Best
food sources -fish liver oil and fatty fish like salmon, swordfish, mackerel,
tuna, halibut, herring and sardines
-
Lesser
amounts are available in beef liver, cheese, shiitake mushrooms and egg yolks
Functions
-
Required
for bone growth and calcium metabolism
-
Absorption
and deposition of calcium and phosphorus in bone and teeth
-
Contributes
towards bone repair by increasing calcium absorption
-
Necessary
for healthy functioning of the parathyroid glands, which regulate the calcium
level in the blood
-
Important
role in prevention of dental caries
-
Extremely
beneficial in treatment of arthritis and tooth decay
-
Reduces
the risk of diabetes, cancer and autoimmune diseases
-
Healthier
skin
-
Strengthens
immunity
-
Important
during infancy and adolescence for the proper formation of teeth and bones
-
Protects
children against rickets
-
Good
supply during pregnancy benefits mother and ensures satisfactory future
development of child
Some more detail
-
Stronger bones - Without vitamin D, calcium is
practically useless in making bones denser and stronger. Calcium and vitamin D
work hand in hand in reducing your risk of osteoporosis
-
Stronger muscles - Vitamin D deficiency can cause muscle
weakness. The vitamin is necessary for skeletal muscles to contract and relax
properly. It helps ward off degradation of protein in muscles
-
Healthier skin – Along with vitamins C and E, it keeps your skin healthy, especially if you
are suffering from inflammatory conditions of the skin like dermatitis,
psoriasis, eczema, acne and dandruff
-
Reduces diabetes symptoms - Regular vitamin D supplementation is
known to help decrease Insulin Resistance and increase sensitivity to insulin.
It is said to considerably reduce the risk of type 1, type 2 and gestational
diabetes
-
Prevention of cancer - It helps in warding off various types
of cancers, including prostate, breast and colon
-
Decreased asthma severity - Vitamin D supplementation helps
improve lung function and enhance the response of asthmatics to treatments
-
Improved male reproductive health - Men with insufficient intake of
vitamin D have lower sperm count and decreased sperm motility
-
Healthier heart - Vitamin D deficiency is linked to
cardiovascular disease
