DR Jose, can I package you up and keep you! 
Yeah we will do fruit, and I will do the diet jello.
As for regular food, there will be cut up veggies. There will probably be a layered salad. There will be little sandwiches (can they eat those?).
My mind is blank, I can't even remember what else we are making. But if I knew what would be good, I would do it.
Although I think most of the diabetics are Filipino, so they may not eat the food anyhow. 
Yep - Diabetes - and other health issues - are prevalent among Filipinos. And, most of "it" is due to the traditional Filipino diet. Lots of pork, lots of salt, lots of oils and fats. Well, more accurately, Filipino-Americans eating like they there were still back "home", but not "acting" like there were still back "home". The typical "country life" in the Philippines is very physical, and most of that physical activity takes place in that very tropical climate, heat. And, as we all know, life in the States - and North America - tends to lean toward the sedentary side. In any case...
Stop apologizing for your food. If people - Filipino or not - are hungry, they will eat. If they're not, well, then you'll have plenty of leftovers.
*I learned a long time ago, that if you expect people not to like, not to eat your food, then they will most likely "fulfill" your intentions.
As for packaging me up... Well, I have a feeling the Canadian tariffs would make that possibility cost-prohibitive.
