Type
2 diabetes is one of the fastest-growing chronic health conditions in
Australia. Nearly two-thirds
of men and half of all women are overweight or obese,
and this extra weight is a major driver of rising diabetes rates.
But
here’s
the hopeful part: up
to 60% of type 2 diabetes cases can be prevented—or
at least delayed—through
healthy lifestyle changes.
It’s
never too late to make a difference. What you eat, and how you move,
matters more than you think.
Here
are six
simple diet tips
you can start today to lower your risk.
1.
Choose Low-GI Carbs
Not
all carbs are created equal. Low-glycemic
index (GI)
foods release energy slowly, keeping blood sugar levels stable and
helping you feel fuller for longer.
Better
choices include:
-
Fruits
like apples, pears, berries, and citrus. -
Wholegrain
breads, cereals, and crackers. -
Legumes
such as chickpeas and lentils. -
Sweet
potato, corn, and pasta. -
Basmati
or Doongara rice. -
2.
Cut Back on Saturated Fats
High
intakes of saturated fat increase insulin resistance and heart
disease risk. Make smart swaps by:
-
Choosing
low-fat dairy. -
Opting
for lean meats and skinless chicken. -
Avoiding
processed snacks like chips, biscuits, cakes, pastries, and
doughnuts. -
3.
Boost Your Omega-3s
Healthy
fats protect the heart and improve insulin sensitivity. Aim for at
least two meals of oily fish per week,
such as salmon, tuna, sardines, mackerel, or trout.
4.
Load Up on Fibre
Fibre
slows glucose absorption and supports gut health. Easy ways to boost
fibre include:
-
Adding
oats, oat bran, or barley to meals. -
Choosing
high-fibre cereals and wholegrain breads. -
Adding
legumes to soups, stews, or salads. -
Eating
a wide variety of fruits and vegetables daily.
5.
Aim for Two and Five
Australia’s
dietary guidelines recommend two
serves of fruit and five serves of vegetables daily.
Fresh, frozen, or canned (no added sugar or salt) all count. The more
colour on your plate, the better.
6.
Rethink Rewards
Food
is often tied to emotions, but rewarding loved ones (especially
children) with sugary treats sets up unhealthy habits that can last a
lifetime. Instead, celebrate with experiences, activities, or
thoughtful non-food gifts that truly nourish your relationships.
The
Bottom Line
Type
2 diabetes doesn’t
develop overnight—but
neither does prevention. Small daily habits around food and lifestyle
can protect your health for decades to come.
Remember,
prevention is always easier than cure. By choosing smart carbs,
healthy fats, fibre-rich foods, and colourful fruits and veggies,
you’re
fuelling your body for a longer,
stronger, and healthier life.
