What is a diabetic diet?

A diabetic diet rule

“Eat the right type of food, in the right amount, at the right time of the day”

There is no such thing as a ‘diabetic diet’. But it is important to make dietary changes that are simple and progressive. First you need to learn what foods should be in your trolley, fridge and kitchen cupboards: that will make good eating decisions easier to choose.

One simple rule

I have one simple rule: eat food that is as close to its natural form as possible! This helps to reduce the amount of processed, high sugar, high-fat foods that cause problems with weight and blood sugar control. Try not to focus on what you can’t have (it is very depressing) and rather be adventurous in experimenting with healthy nutritious meals.

Once you know which foods are suitable, you need to get specific and work out how much to eat. Portion control is very important. The good news is that almost all foods are allowed in correct portions.

Some general rules

Starch: Use low GI, high fibre starches. Reduce foods made with lots of white flour and sugar (doughnuts, biscuits, cakes ). For your main meal, the portion size of starch should be the size of your fist (approximately 2 portions of starch).

Protein: Opt for low-fat protein. Remove visible fat from meat and skin from chicken. For your main meal, the portion of protein should be the size of the palm of your hand and the same thickness as your baby finger (less at other meals)

Dairy: Choose low-fat or fat-free dairy. Try for 2 portions of dairy a day.

Vegetables: Choose a variety of colours and serve raw, steamed and roasted. Eat lots – double portions where possible!

Fruit: Try to eat a variety of fruits. The size should be that of a tennis ball and you should aim for 2 servings of fruit a day.

Fat: Try to reduce the use of fats in your cooking. Rather grill, bake, boil, steam, microwave or stir-fry your food. The portion of fat should equal the size of the tip of your thumb.
