There are several reasons to consider avoiding both sugar and wheat. The most obvious of these is that a person is diabetic and the carbohydrates from the wheat will turn into sugar in the body. However, those who suffer from Celiac disease and who also need to limit their sugar intake (for instance, to lose weight or because they are also diabetic) may also need to avoid such things.
These crackers are made by a New Jersey-based company, and most of them (with the exception of the Fruit Crunch flavor) are sugar-free and wheat-free. Though the company offers one variety which contains wheat, that variety is processed in a different facility than the wheat-free varieties.

Garcia Lo Tortilla Chips
Not only do these contain no sugar or wheat, they are actually good for you; they contain Omega 3-rich flaxseed. The chips come in several flavors, including blue corn, multi-grain spicy, plain, spicy, Thai and veggie. They can be ordered online from a variety of retailers, including Amazon.com and Vitacost.com.
Barley and Oats
Cooked barley and cooked oats are natural choices for those needing to avoid both wheat and sugar. Barley can be cooked by boiling one cup of barley with four cups of water. Wait until the water boils out completely, but make sure the barley doesn't start to burn. Oats are cooked the same way, using one cup of oats to four cups of water. In both cases, any flavorings you'd like to add (such as spices or raisins) should be added before you start cooking.
