1.Blood Sugar Problems

This is one of the serious side effects of pineapple. Pineapples have been found to heighten blood sugar levels. Although maintaining your blood sugar levels is important, you must also consider your carbohydrate intake. Most fruits contain carbohydrates and these can also raise the blood sugar levels. ½ cup of pineapple has 15 grams of carbohydrates.

Pineapple is considered a “medium” fruit on the glycemic index, so you should consume it in small portions. A serving of ¾ cup of fresh pineapple has a glycemic index score of 56.
When using pineapple in meals, it’s best to pair it with foods that have a low or medium glycemic index score. This can help you avoid sugar spikes.
