There is one essential difference between food manufacturers and food consumers: we, the consumers, want food to be nutritious whereas the manufacturers want food to be sold. This explains why one kind of food even within the same brand produced by the same manufacturer may be healthy and another one, just next to it, may not.
On the package you read: “Wheat Thins Original Snacks have 21 g whole grain per 31 g serving. Nutritionists recommend eating 3 or more servings of whole grain foods per day (about 16 g whole grain per serving or at least 48 g per day).” Indeed, from 22 g of carbohydrates per 31 g serving of Wheat Thins Original only 3 g are sugars! Of course, this does not mean that you can indulge yourself to eat the whole package at once because any food can turn toxic if over-consumed but with Wheat Thins Original you will take zero foreign chemical additives risk of DDFI = 0/19 = 0 and you will get descent nutritional value of DDNF = 19/15 ~ 1.3. Yes, Wheat Thins Original are safe to eat in moderation! Enjoy!
Please note that while most of the Wheat Thins are nutritious and safe, e. g. Sundried Tomato and Basil, Parmesan and Basil, some of them may be relatively inferior because of foreign food additive presence. For instance, they add Red 40 Lake, which is potentially carcinogenic (read CSPI report Food Dyes: A Rainbow of Risks p. 29 – 32) to Wheat Thins Ranch.
