Sugars are necessary in our diet

No. Sugars are not essential nutrients. They are one of several sources of dietary energy. White, brown or raw sugar, glucose (dextrose), corn syrup, invert sugar or honey do not contain significant quantities of other nutrients. It is better to obtain our energy requirements from other foods. If we obtain our energy from foods such as meat, fruit, cereals or vegetables, we also gain the nutrients present in these foods.
