Fruits are a healthy food choice to improve overall health and manage diabetes. However, the question arises: “Does fruit increase blood sugar?” While fruits do contain natural sugars, they also provide vital nutrients and dietary fiber. There are certain fruits that have a higher glycemic index and can potentially cause an increase in your blood glucose levels.

In this article, we will explore various fruit types and identify the fruits to avoid when dealing with diabetes. By understanding the impact of different fruits on blood sugar, individuals can identify the worst fruits for diabetes and make suitable adjustments to their diet.

Which are the Fruits to Avoid When You Have Diabetes?

As such, there are no fruits to avoid in diabetes, as there are many health benefits that you can get when you make fruits a regular part of your diet.

However, one of the things that can make it easier for you to take care of your diabetes and eat fruits is to understand which fruit is higher on the glycemic index and how to manage your portion sizes for the same.

The glycaemic index or GI score is how fast blood sugar increases after consuming that food in comparison with glucose. It gives an idea of how fast a particular fruit will affect your blood sugar levels once you eat it.

Here are some fruits to avoid in diabetes that are high on the glycaemic index score, but with a little tweaking and with your doctor’s permission, you may still enjoy these:

1. Mangoes 

  • Mangoes have a glycaemic index of about 60, making them high on the GI score. 
  • Almost 90 percent of the calories present in mangoes come from the number of natural sugars it has.
  • As a result, eating a bigger portion of mangoes can directly impact your blood sugar levels and make them spike. 
  • If you want to eat mangoes, try having a smaller portion and a few pieces at a time instead of having a full mango alone.

2. Ripe Bananas

  • Ripe bananas have a GI of about 51, which is still a bit higher, especially if you have diabetes.
  • The green variant of bananas, which are not as ripe, has a GI of 42 is a good source of resistant starch. It has minimal impact on your blood sugar levels and will not cause a spike. 
  • If you love eating bananas, go for the elaichi bananas, which are smaller.
  • Besides that, you can also use unripe bananas as a vegetable option and get all the healthy nutrients that it has to offer for your diabetes as well as overall health, but be mindful of portion size while consuming.

3. Pineapple or Ananas 

  • Pineapples have a high glycaemic index of about 51 to 73 and rate relatively high on the GI score. 
  • The impact of the GI score of pineapple on your blood sugar levels will also change based on how ripe the pineapple is and how you consume it
  • In fact, pineapples have a higher chance of impacting your blood sugar levels as compared to when you eat other fruits.
  • Including other foods in your diet that are high in healthy fats or protein while you are having pineapple is a good idea. For instance, if you are having some pieces of pineapple, you can also have some healthy nuts and seeds to limit the effect the pineapple will have on your overall blood sugar level.
  • If you love eating pineapples, watch the amount that you eat and only stick to a few pieces at a time.  

4. Watermelons or Tarbooz

  • Watermelons stand very high on the glycemic index, with a GI score of about 80, which is considered extremely high.
  • Eating watermelon is recommended if you love eating only a few pieces or slices at a time.
  • Also, instead of having watermelon juice, go for a plain watermelon slice, as the watermelon juice can tend to have a higher impact on blood sugar levels and make them spike. 
  • Just like eating pineapples and including nuts or seeds and food items, it is also recommended to eat other food types when you have watermelons. 
  • Try and include other food that is high in fiber content and protein or good fats. This will help you minimise the amount of watermelon you eat while also getting its benefits.

5. Chikoo or Sapota

  • Chikoo falls into the category of fruits with a moderate GI of 57, which is moderately high for people with diabetes.
  • This means that consuming Chikoo may cause an increase in blood sugar levels.
  • If you want to eat Chikoo, choose it based on your blood sugar control; if your blood glucose level is under control, you can have a small piece of chickoo or else avoid it.
  • It is crucial for people with diabetes to practice portion control when consuming chikoo.
  • Combining smaller servings with other low-glycemic foods like almonds, walnuts, or avocados can help manage blood sugar levels more effectively. 

6. Custard Apple or Sharifa/Sitaphal

  • Being delicious in taste, custard apple has a GI of 54, which is again moderately high.
  • Custard apple can be an option for people with well-controlled diabetes, as long as you keep the portion in control.
  • Consuming small servings and combining them with other low-glycemic foods like nuts and seeds can help prevent significant fluctuations in blood sugar levels.
  • Custard apple is rich in vitamins, minerals, and antioxidants, which contribute to overall health and well-being.
  • However, people with diabetes should focus on the fruit’s impact on blood sugar levels and consider portion control.

Among the worst fruits for diabetes, those with a higher glycemic index should be approached with caution to prevent spikes in blood glucose levels.

Types of Fruits to Avoid

A diet rich in fruits with low GI and vegetables is recommended for managing diabetes. But always remember, after you consume any fruit, check your blood glucose; this will help you to decide which fruit to avoid and how much portion/quantity you can consume.

Some points you should keep in mind:

  • One should not avoid fruits for diabetes, but for those with a lower carbohydrate content are always a preferred option
  • Fruit should never be eaten after or with meals like a dessert. There should be a gap of 3-4 hours between food and fruit
