What is diabetes?

Diabetes Mellitus is a common condition which causes an elevation of sugar (Glucose) levels in the blood. Around 3.5 million people have been diagnosed with the condition in the UK, and it's believed a further estimated 850,000 or more are living with the condition undiagnosed. It is the leading cause of adult blindness and amputation and is a major cause or renal failure, heart attacks and strokes.

Normally, the body controls the level of glucose in the blood by producing a hormone in the pancreas called insulin, glucose from dietary carbohydrate and the liver is allowed into the cells by insulin to then be broken down into energy. However, when this normal body system doesn't work correctly or begins to work less well, it is known as diabetes.

Two types of diabetes

There are two main types of diabetes: Type 1 and Type 2. Of the diagnosed cases, 10% have type 1, which is most common in the under 35 age group with onset and symptoms usually showing and developing rapidly during childhood or puberty. 90% of cases have type 2, which is most common in the white over 35's and South Asian over 25's populations, with onset and symptoms developing gradually.

However, an increasing number of children are now being diagnosed with type 2 diabetes.

Type 1 diabetes

In type 1 diabetes, no insulin is produced at all, this is because the bodies immune cells have destroyed the cells that produce insulin in the pancreas. At present, the reason this happens in some people and not others is still not fully understood. Type 1 diabetes can be successfully treated with insulin administration either through an injection or pump, as well as by eating a healthy balanced diet and taking part in regular physical activity.

Type 2 diabetes

Type 2 diabetes can develop when, over a long period of time there has been a regular high intake of sugar (glucose), as the insulin receptors are constantly being stimulated to produce insulin, the receptors begin to become less sensitive, so work less effectively. This means less glucose is removed from the blood, leaving levels elevated

Type 2 diabetes can be treated and managed with a change in lifestyle to a healthier diet and an increase in physical activity. Medication and/or insulin injections are often given on first diagnoses in order to reduce blood sugar levels.

Food and diabetes

Many people think that if someone is diabetic they need to be on a special diet, can only eat certain things and can't eat sugar at all. The reality is, a diabetic diet is no different to the healthy, balanced diet we should all be enjoying. Whether diabetic or not, the important thing for our bodies and the way we feel, is to try to eat in a more healthy way by choosing less processed and more natural whole foods and leaving longer time between meals. this will not only help to maintain a healthier weight, but also help the body reduce inulin sensitivity. Thereby keeping our blood sugar levels as steady as possible.

Below are some good dietary changes we can make to help us all with this:

Diabetic foods

Avoid buying any foods labelled as 'diabetic', they are expensive and a waste of money, these types of foods offer no special benefits to people with diabetes and often contain just as much, if not more calories and saturated fat as ordinary versions.
