Dried Fruits

Fruits are a great source of many essential nutrients such as vitamins and minerals. A high level of water concentration is reduced when fruits are processed into dried fruit. As a result, nutrient concentration, as well as sugar concentration, increases in them. So, you must avoid having dried fruits in your diet.

Packed and Stacked Food

Diabetes patients should be cautious while choosing snacks. Snacks such as crackers, pretzels, and some other packed snacks should be avoided. Most of the snacks are processed food made from flour and don’t provide many nutrients. Also, they contain enough carbs that can result in a rapid increase in blood sugar levels.

French Fries
