I imagine not, like some of the foods that exist now, I am certain that depending on your race and the type of food you're eating that you will gain or perhaps even lose a specific amount of hunger. Such as with the Apex banana and the Ocumelons, these state explicitly that they will probably make anyone besides Apex (In the case of the banana) and Floran (In the case of the Ocumelon) sick. If this is the case, the starting difficulty for a Phobe might be slightly higher than that of other races who might find a greater nutritional value in the alien meat, the food they will mostly likely first obtain. That isn't to say that plants, biomes, and other naturally occurring sources of "sugar" foods won't exist. Such as the Neonmelon, which would be richly nutritious for a Phobe.
