Actually, even if you don't add sugar to your homemade juice, the calorie count doesn't decrease at all. According to research by European diabetes experts, a 100ml glass of orange juice contains 15 grams of carbohydrates and 60 kilocalories (equivalent to 50 grams of rice). This might not seem like a lot of calories, but on a hot summer day, if you indulge in freshly squeezed orange juice, you probably won't stop at 100ml. Most people will drink at least 200-300ml each time, which will inevitably lead to a spike in blood sugar.
Therefore, it's best for diabetics to drink less freshly squeezed juice. It's better to eat whole fruits instead of drinking juice. Compared to juice, it's easier to control the quantity of whole fruits, and they are rich in fiber, which helps you feel full.
If you really can't kick the habit of drinking freshly squeezed juice, when you make your own, it's best to consult a calorie chart for fruits. At the same time, you should monitor the effect this juice has on your blood sugar. For example, check your blood sugar before drinking, then check it again two hours after, and compare the two readings to see if this particular juice and quantity are suitable for you.
