Here are seven foods that can cause a spike in blood sugar levels:

Fruit Juice: Even though fruit juice is made from fruit, it often lacks the fiber that helps slow down the absorption of sugar, therefore increasing in blood sugar levels.

Processed Snack Foods: Many processed snack foods often contain refined carbohydrates and added sugars that can lead to spikes in blood glucose.

White Rice: White rice is a refined grain that is quickly digested and can cause a spike in blood sugar levels.

Potatoes: While potatoes are a nutritious vegetable, they are high in starch, which can quickly convert to glucose in the body and raise blood sugar levels.

Candy and Sweets: Sweets contain high amounts of simple sugars that are rapidly absorbed into the bloodstream, causing a rapid rise in blood glucose.

Sugary Drinks: Beverages like soda, sweetened fruit juices, and energy drinks are high in added sugars, which can cause a sharp increase in blood sugar levels.

White Bread and Pastries: Foods made with refined flour are quickly broken down into sugar in the body, leading to rapid spikes in blood glucose levels.
