Type 2 diabetes is one of the fastest growing chronic diseases and is becoming increasingly prevalent among adolescents and children. Nearly a quarter of a million New Zealanders have been diagnosed with type 2 diabetes and some people are living with the disease but don’t yet know it.

So what can you do to reduce your risk of developing diabetes? Here are five lifestyle tips.
Carrying extra weight, especially around your middle, is a key risk factor for diabetes. Aim to achieve a healthy weight - even losing a few kilos can significantly reduce your risk.
Focus on wholefoods
Evidence is accumulating that the best way to prevent, treat and even reverse diabetes is with a plant-based diet.
Basing most of what you eat on a variety of wholefoods, including wholegrain breads and cereals, fruits and vegetables, legumes, nuts and seeds will help to lower your risk of diabetes.
Try replacing some meat meals with plant proteins such as legumes as these are high in fibre and help to manage blood sugars. At the same time, it’s important to limit highly processed high fat and high sugar foods.
Choose low GI carbs
Low GI (glycemic index) carbs help manage blood glucose and keep you feeling fuller for longer, which means you snack less, have fewer cravings throughout the day and can concentrate better. Low GI carbohydrates tend to be wholegrains and include brown grainy breads, brown long-grain rice, traditional rolled oats, wholemeal pastas, quinoa, buckwheat and barley.

Choose healthy fats every day
Nourishing plant fats from wholefoods, such as extra virgin olive oil, unsalted nuts and seeds, nut and seed butters and avocado will help slow the release of glucose into your bloodstream, meaning better blood-sugar control. They will also help to reduce inflammation in your body, which has been linked to a range of chronic diseases, including diabetes.

It's important to get your blood glucose levels checked by your doctor at least every year or two, especially if you’re overweight or have a family history of diabetes. If you do have diabetes in your family, remember that while it does increase your risk, it doesn’t mean you'll develop the disease. Take control to reduce your risk.

There are three types of diabetes:
Type 1 diabetes
This is an auto-immune condition when the body’s immune system destroys insulin-producing cells in the pancreas. This means that people with type 1 diabetes can’t make their own insulin and need to use insulin injections or an insulin pump several times each day.
How is it caused?
It is not yet known what causes type 1 diabetes and no cure has yet been found.
Type 2 diabetes
This is a lifestyle-related condition and is a chronic disease. It’s most commonly found in adults over 45, although we are now seeing children as young as five being diagnosed with type 2 diabetes due to the increase in childhood obesity.
How is it caused?
Type 2 diabetes is mainly caused by extra body weight and poor eating and lifestyle habits.
This is a type of diabetes that occurs during pregnancy. It normally goes away after the baby is born, although it does increase the risk of the mother developing type 2 diabetes in the future.
Gestational diabetes can generally be managed by following a healthy lifestyle but for some women, insulin injections may be required.
