Obviously, the requirements of sugar gliders are of importance to their overall health, and they are prone to metabolic bone disease resulting from an improper ratio of calcium to phosphorus in the diet. If a diet is relatively higher in phosphorus than calcium, calcium will be leached from the bones and other tissues to balance the levels in the blood. This results in a softening of the bones, making them susceptible to fractures, along with a myriad of other health problems related to calcium imbalance.
Sugar gliders in the wild feed on eucalyptus gum, sap, insects, nectar, and honeydew (an excretory product of nectar eating insects). They will also eat bird eggs, lizards, small birds and other small prey items. This diet is pretty difficult to replicate in captivity. So a variety have food have been fed, in an attempt to somewhat mimic their natural intake and to see what makes them thrive in captivity.
But what is the ideal diet? I don't believe that is an easy question to answer, and I do not keep sugar gliders so cannot speak from personal experience. The Sugar Glider Resource Center has a great section on feeding and diets that lists numerous diets that are recommended by various people involved in sugar glider care.

What follows is dietary advice from well known exotic animal veterinarian and and (next page) an Australian Zoo.
Dr. Johnson-Delaney Recommendations
Dr. Cathy Johnson-Delaney is an experienced exotic animal veterinarian
and respected author and speaker. Her feeding recommendations are based
on studies of the natural diets of sugar gliders designed in consultation with Australian zookeepers and veterinarians. The
suggested amounts are per sugar glider, per day, fed in the evening.
The amount should be adjusted depending on activity, size, reproduction,
etc.
- 1 Tablespoon Leadbeater's Mix (recipe follows)
- 1 Tablespoon Zoo quality insectivore diet (e.g. Reliable Protein Products Insectivore Diet) , or insects. If using insects, variety is important (crickets, mealworms, waxworms, moths, spiders, etc), and the insects should be fed high quality food such as commercial cricket food, and dusted with a complete vitamin/mineral supplement.
- treat: small amount of fruits, chopped together so the gliders can't just pick out ther favorites.
- Leadbeater's Mix Recipe
150 ml Warm water
150 ml Honey
1 Shelled, boiled egg
25 grams high protein baby cereal
1 tsp vitamin/mineral supplement
