“Will eating fruits every day increase my sugar levels?”

This question and many questions can be answered by what happens with monitoring. I recommend a continuous glucose monitor, I would not eat unless the glucose is less that 120 and eat slowly, slowly with a downward arrow on the glucose monitor. Stop eating when the glucose measures 140. Usually fruit does raise the sugar. Miralax works well. Best Dr. Norwood

Fruits contain fructose that breaks down into glucose in the blood and increases blood sugar.

Probably not too much. If you do not have diabetes, it will probably have no effect. If you have diabetes or are at a high risk for it, it may elevate your blood sugar some. It depends a lot on what kind of fruit you eat. Bananas are high in sugar, but have little fiber, so it's probably not good to eat too many of them. Since you are eating for the fiber, bananas would not be a good fruit. Oranges have a lot of fiber, particularly if you eat the orange; the juice may have had the fiber strained out. Grapes have a very high sugar content. That's why we make wine out of grapes rather than other fruits. Grapes, especially in the form of raisins, have a lot of fiber, but also a lot of sugar. Apples are low in glucose sugar (they have other sugars that are less harmful), so choose a good fruit to use. For you, check the sugar content and fiber content to select the right fruits for your needs and you should be okay. Enjoy, as most fruits are good for you.
