Added sugars, such as cane sugar, corn syrup and honey, add sweet flavor, but few nutrients, to foods. Similar to refined grains, they are high-glycemic and may interfere with blood sugar control. In addition, diets rich in added sugars are associated with poor nutrient intake. To guard against nutrient deficiencies, which can lead to neuropathy symptoms, choose nutritious foods, such as fruits, vegetables and whole grains, instead of sugary fare most often. Common sources of added sugars include regular soft drinks, candy, milk chocolate, sugary cereals, pancake syrup, jellies, frozen desserts and commercially baked cakes, cookies, pastries and pies.
