Vitamin D, the fat soluble vitamin important for Bone Health, Calcium & Phosphorus absorption is effective against multiple disorders. Deficiency of this vitamin leads to rickets in children and osteoporosis in adults and hence it is important to meet the daily requirement of this vitamin. As per a latest study Low vitamin D can make young women depressed

Why the deficiency

Irony is that in a country lit with bright sunlight right through the year, Vitamin D deficiency is being reported to be rapidly increasing both in Indian males & females.

It might be due to-

(1) lack of exposure to sun (being indoors and in ACs through the day ),

(2) pollution in the air,

(3) weather conditions for eg . cloud cover,

(4) excess pigments in our body which hinder its absorption or other factors affecting absorption.

Ponder how often we step out in the sun and even if we do,how much Sunscreen we apply to protect our skin from the tan !!

 

How can you meet your daily requirement

Interestingly this is the only vitamin that can be synthesized by the body on exposure to sunlight , so it is often called the SUNSHINE VITAMIN. The good news is that most people can get enough Vitamin D.However, if you don't spend enough time in the sun or if your body has trouble absorbing the vitamin, you may not get enough.

Sunlight spurs the body to make vitamin D and a small amount of sun exposure without sunscreen can do the trick. About 20-25 minutes of exposure is helpful.The sun is less likely to provide your daily needs at higher latitudes, in the winter, or if you're older or dark skinned (skin pigment blocks light and the process is less efficient with age). And very importantly Light through a glass window pane would not be effective.

Sunlight is the most important source of Vitamin D and its not very easy to get from the dietary sources

 

Among foods,Fatty fish like salmon,tuna,mackerel,Cod,herring,sardines are good sources.

Egg yolks also have vitamin D ,and its important to have whole eggs for it. Among meats, chicken breasts,pork  n beef liver are also considered good sources.

You may also find many cereals,oils,butter, milk n milk products,orange juice,etc which have been fortified with Vitamin D.

Vitamin D is present in good amounts in some varieties of mushrooms such as white button, wild edible and chanterelle.

Besides,Vitamin D or Cholecalciferol supplements are required often to meet the requirement. Vitamin D supplements can help you get your proper daily dose.Too much vitamin D can be toxic,so talk to your doctor before choosing a dosage.

Fasting has various advantages for our body.       Few people also plan to lose weight during Navratras while being religiously inclined.   Here I bring for you a few tips which would make your Navratra Fasts healthier and also would make you shed a few kilos :   Avoid all fried foods like chips, deep fried cutlets, pooris,etc  even if you are taking one meal a day. Keep yourself hydrated with lots of water, carrot-tomato juice, nimbu paani, green tea, tea,buttermilk , skim milk,coconut water , etc Keep eating small portions of fruits or other permitted food items to keep your metabolism alive. Do not under-eat or keep hungry for long. Also do not over-eat  in a single meal. Avoid sugar laden sweets and desserts. Instead prepare fruit smoothies in curd, fruit chaat, etc for that sweet taste. You can include Bananas,Boiled potatoes, saboodana ( Sago ),samak ke chawal ( sanwa millet ),kuttoo ( buckwheat ),singhade ka atta ( water chestnut flour ), etc in your meals which would not only provide the necessary energy but also many micronutrients. Keep doing your normal physical activity and don’t just lie down thinking that you are ‘fasting’ and need to avoid physical  activity. Avoid over indulgence in heavy meals and fried foods after late night “Garbas or ‘Dandiya’. Have a mini meal before leaving home to attend Garba or Dandiya Parties . ‘Sendha Namak’ is also Sodium Chloride chemically as is your Common Salt, so its use also has to be limited if you have been advised so. Extra precautions must be taken by people prone to health risks while observing fasts. These include people suffering from diabetes, hypertension, anaemia, and those who have recently underwent some kind of surgery. Individuals with chronic health problems related to kidneys, heart, liver or lungs must observe fasting only after consent from their doctors. Pregnant and lactating women must also be precautious.                                  WISHING EVERYONE A HAPPY AND HEALTHY NAVRATRA…………Dr.Shalini Singhal
