Banana and Diabetes - Everything You Need To Know

The dietary requirements of a diabetic person often restrict the consumption of sugars, carbohydrates, and starch. The food items that are recommended for people with diabetes have very less sugar and most food items need to be portion-controlled. It is a misconception that all fruits are bad for diabetic people. It is true that fruits contain natural sugars, however, they can be consumed in moderate quantities. One such fruit that has fallen prey to rumors is the banana. The most common question asked pertaining to this fruit is, is banana good for diabetes?

Can Diabetic Patient Eat Banana?

Just like all fruits, bananas contain sugar and carbohydrates that are considered harmful for diabetics. However, unlike processed goods (candy, cakes, sweets), they come with a package of fibre, potassium, vitamins, and other nutritive perks. So, if you are asking, can diabetic patient eat banana, the answer is yes. However, there are some conditions that need to be followed. Let us take a look at the factors that should be considered.

  • Ripeness of the banana – The number of carbs and sugar content in a banana varies with its ripeness. There are various recipes that make use of unripe bananas as well. Fully ripened bananas contain less resistant starch, which acts like fibre. They also have a higher glycemic index that causes blood sugar to rise. Green bananas contain more resistant starch that can help you manage your blood sugar levels. They are also helpful for improving the health of your gut and improving the metabolic health of the body. So, the next time someone asks you, is raw banana good for diabetes? You can say it is. 
  • Portion control – It is quite obvious that the larger the banana, the higher is the sugar consumption. This means you need to account for the sugar intake as well as the carbohydrate intake throughout the day. 
  • Eat them at intervals – Try not to consume all your portion of banana in one go. This may spike your sugar levels. The wise thing to do is spread it over the duration of the day to enjoy the benefits of bananas while keeping your blood sugar under control. 
  • Pair them with other foods – When you eat only a banana, the body immediately absorbs all the nutrients from it. If you want to slow down the absorption of sugar, you can pair it with other food items that do not have a high GI and are devoid of carbs. You can put them in a bowl of oats, have it with yogurt, put them in a chia pudding, and so on. When you eat other food items with it, the body absorbs the sugar slowly giving it enough time to process sugar slowly. 
  • Be wary of the preparation – Many companies have advertised processed bananas as a healthy snack. The catch is, they are often deep-fried, and avoiding saturated fats is one of the must-dos of diabetes. If not friends and just bakes, they can still contain added sugars and other ingredients that may compromise the integrity of the fruit. Canned bananas are a big no-no as they contain sugar as the primary preservative. If you are a fan of milkshakes and smoothies, avoid going out and eating these as you cannot control the amount of sugar that is added. 
  • Sensitivity of the body – Although bananas are recommended in controlled proportions, it is essential to know your own body’s sensitivity to insulin as well as sugar. That is why the answer to most people’s question, can banana be eaten in diabetes, is different. The sugar in bananas can react differently with different body types, depending on a lot of complex factors. Understanding the response your body has to bananas is important before you consume them when you have diabetes.
