Did you Know These Dreadful Facts?
Around the globe, Diabetes Mellitus Type II sufferers are estimated to increase up to 438 million by 2030. A chronic lifestyle disease, Diabetes highly increases mortality and decreases the mobility and quality of life in its sufferers. Long time uncontrolled diabetes affects the nerves, auditory and vital organ functions and cause heart disease.
In 2010, approximately 79 million Americans aged 20 or older were already affected by prediabetes, the precursor to diabetes. Prediabetics have higher than normal blood sugar levels, insulin resistance and without any other symptoms that meet the criteria for diabetes. They are expected to develop diabetes in the next 5-10 years if they do not make the necessary and preventive lifestyle changes.
The Clue in Vitamin D
Researchers vouch on a link between Vitamin D and other diseases like cancer, diabetes and heart disease.  Vitamin D is that nutrient which can be received only through sun light and from Vitamin D fortified food products. It has many functions including the absorption of calcium, modulation of cell growth, neuromuscular and immune function, and reduction of inflammation.
Insulin Resistance occurs when the body is insensitive to the presence of natural insulin and does not make use of it. As a result, less glucose is used up causing a hike in the blood glucose levels. Those with Insulin Resistance always stand a greater chance of developing diabetes on a later date.
Studies have witnessed that those who were on high doses of Vitamin D have shown better Insulin Sensitivity in time than others. They also are much safer from diabetes than others who received low Vitamin D on a daily basis. The participants of these studies had had a smaller waist circumference, higher HDL cholesterol and lower blood sugar.
Vitamin D Daily Dosage
When you really think of it, there is no real consensus regarding the recommended dosage of Vitamin D.
The U.S.  recommendation of Vitamin D is 200 IU for those between the ages 19 and 50, 400 IU for those aged 51 to 70, and 600 IU for those above the age of 70. In Britain, they recommend a daily supplement of 1,000 IU for those at risk of Vitamin D deficiency. However, these dosages are perhaps based on how much (or how less) sun exposure the residents get. In countries like India where we get a lot more of sunlight, the dosage might be lower.
Warning note: Always talk to your doctor before taking supplements. Higher doses of vitamins and minerals are harmful.
