Wild sugar glider feed on plant exudate's, mainly sap and gum, as well as insects and live baby birds.  Live insect food is the preferred protein source for captive gliders (15-25 meal worms per meal), but this can be supplemented with a commercial small insectivore mix. The tree sap can be supplied via maple syrup (The sap of the Maple tree) which has a substantial mix of minerals compared to honey. The commercially available syrup should be diluted 50:50 with distilled water, offered in a sipper and made fresh daily. This mixture ferments in hot weather and may need to be replaced twice daily in hot climates.

Although nectar is not a major component of the wild diet, it is nutritionally similar to sap. A simple nectar mix can be made from 1.5 cups of brown sugar, 0.5 cup glucose made up to 2 liters with warm water. A simple dry nectar mix can be made from 1 cup of rolled oats, 1/4 cup of wheat germ, 1/4 cup brown sugar, 1 tablespoon glucose powder, 1 tablespoon of raisins.

Gum Arabic, which can sometimes be obtained from pharmacies, is gum derived commercially from African Acacia species and provides a suitable approximation of this major component of the natural diet. The sugar gliders enlarged cecum is adapted to facilitate microbial fermentation of the complex polysaccharides obtained from acacia gum.

Food for adults should be limited to 15 to 20% of body weight daily as obesity is common in pet sugar gliders. 

Treat foods include a range of fruits and nuts but these should never exceed 15% of the diet(eg, apple, nectarine, figs, grapes, peaches, apricots, pears, cherries, kumquats). Acacia or eucalyptus branches provide suitable behavioral enrichment. Holes can be drilled in branches and filled with the gum mixture to simulate natural feeding behavior. The provision of some abrasive components in the diet is necessary to avoid tartar buildup.

This is 80% of their diet, every zoo in America feeds this exact same brand and diet.
