The level of increased blood sugar depends on the amount of pineapple eaten, the ripening of the fruit, the eating time and the metabolism of each individual.
Pineapple is a tropical fruit rich in vitamin C, manganese, and antioxidants. However, many people are hesitant to eat pineapple because they think this fruit contains a lot of sugar.
In fact, pineapple has a glycemic index (GI) from medium to relatively high depending on variety and ripeness, meaning it can increase blood sugar faster than some other fruits if eaten too much.
For people with diabetes, a serving of fruit can usually provide about 15g of carbohydrates. With fresh pineapple, this amount is equivalent to about 80–100g of peeled pineapple, which is about a small cup or 2 thin slices. This is considered a relatively safe serving to help utilize the nutritional value of pineapple without causing a sharp increase in blood sugar in most adults.
For healthy people, you can eat about 100–150g of fresh pineapple each time as part of a snack. Meanwhile, people with pre-diabetes or diabetes should limit it to about 80–100g each time and monitor personal glycemic reactions. More importantly, you should not eat pineapple on an empty stomach or eat a large amount in a short time.
You should eat fresh pineapple whole instead of drinking juice. When juiced, most of the fiber is removed, making sugar absorbed faster and easily causing high blood sugar. Pineapple should be combined with foods rich in protein or healthy fats such as unsweetened yogurt, nuts or low-fat cheese to slow down sugar absorption.
Another note is that overripe pineapples often contain a higher amount of easily absorbed sugar than just-ripened pineapples. Therefore, people who need to control blood sugar should prioritize medium-ripened pineapples, avoid dried pineapples, pineapples soaked in syrup or canned juices with added sugar.
Eating about 80–100g of fresh pineapple each time, equivalent to 2 thin slices or a small cup, usually does not significantly increase blood sugar when combined in a balanced diet.
The important thing is not to completely abstain from pineapple, but to control portion sizes and choose a suitable way of eating to both enjoy the delicious flavor and protect health.
