Fruits are generally healthy, but not all fruits are safe for diabetes patients. Some fruits contain high natural sugar and can quickly raise blood glucose levels if eaten in large portions.
In this post, we will discuss the worst fruits for diabetes patients, why they increase blood sugar quickly, and how to consume them safely if needed.
🍉 Why Some Fruits Raise Blood Sugar Fast
Certain fruits:
Have a high glycemic index (GI)
Contain high natural sugar (fructose)
Lack enough fiber to slow sugar absorption
When eaten in large quantities, they can cause rapid glucose spikes.
