Diabetes (Diabetes Mellitus) is a chronic condition that is caused by inadequate secretion or action of insulin (a hormone produced in the pancreas gland – the pancreas), and which is responsible for the metabolism of carbohydrates ie sugar (Langerhans cells of the diabetic pancreas does not secrete enough insulin). Without insulin, glucose can not be transferred to the cells, which causes an increase of glucose in the blood.
Diabetes has spread around the world and came to the point where it became an epidemic. Currently, seven per cent of the global population suffers from diabetes and type 2 diabetes is usually caused by sedentary lifestyles and obesity. People with lots of vitamin D can halve their chances of developing heart disease or diabetes, the study found.
There are two main categories of diabetes:
Type 1 diabetes occurs in childhood or adolescence and insulin is required in treatment. Caused by the very immune system that destroys the body cells in the pancreas that produce insulin (beta cells).
Type 2 diabetes usually develops gradually in adults and progresses with time. Initially, type 2 diabetes is usually treated successfully with diet, increasing physical activity and, if necessary tablets. Over the years the secretion of insulin in the pancreas may become insufficient insulin treatment is needed.
What is insulin?
Insulin is a hormone of vital importance produced by pancreas beta-cells. Insulin has a key role in the leakage of sugar (glucose) in cells.
In diabetes, the pancreas produces too little insulin to allow all the sugar which enters the body through food transfers from the blood into muscles and other cells that produce energy. If sugar can not enter cells to be used it accumulates in the blood. Because of that, a fundamental feature of diabetes is elevated blood sugar, which causes long term damage to the eyes, nerves, kidneys and blood vessels, and these are called chronic complications of diabetes.
Vitamin D deficiency effect on diabetes
People with lots of vitamin D have almost halved the risk of developing heart disease or diabetes, according to a survey of U.S. experts. They reviewed 28 existing studies which included over 100,000 subjects and focused on vitamin D levels in middle-aged and elderly people.
Researchers at Warwick Medical School have found 33 lower risks of developing cardiovascular disease, 55 per cent less likely to develop type 2 diabetes, while the risk of metabolic syndrome halved in people with a lot of “sunlight vitamin”.
Metabolic syndrome is the name of the group of risk factors for heart disease and refers to a body mass index greater than 30, a waist circumference greater than 94 inches for men and 102 cm for women, blood pressure higher than 135/85, fasting glucose levels greater than 100 mg/dl and the other parameters.
Most people can increase their concentrations of vitamin D to prevent deficiency as well as to lower the chances of getting diabetes through nutrition, and exposure to sunlight – at least 30 minutes twice a week. It should be noted that doctors warn against excessive sun exposure because it causes skin cancer and damages the skin.
Certainly, vitamin D deficiency has a great effect on the development of diabetes, just like many other diseases, so you should work on entering the required amount of vitamin D in the body.
“We recommend a healthy diet of two to three servings of fatty fish a week and five portions of fruit and vegetables. About 90 per cent of Vitamin D comes from sunlight, and therefore a reasonable exposure to the sun is recommended, ” said Dr Johanna Parker, one of the authors of the study.
Food rich in vitamin D is salmon, tuna, mackerel, sardines, margarine, egg and liver.
