Full-fat dairy products
You definitely need to stay away from saturated fats because they raise the levels of bad cholesterol or LDL cholesterol which increases your chances of getting heart disease.
Heart disease is a great concern for people suffering from diabetes.
These products, being high in saturated fats, increase insulin resistance which makes things worse.
So, skip that full-fat yoghurt, cream, ice cream, butter or cheese and choose dairy-free versions.
If you have to take dairy products, then go for those that have reduced fats such as coconut milk.
