I’ve been going to shul every Saturday morning for about 20 years or so. I have stopped recently but that is outside the scope of this topic. After the weekly 4 hour service, which was boring, there was a ton of a food at a luncheon type of deal called a kiddush. One thing that is consistent about every kiddush I have been to, is the food is stale and generally unhealthy. You would have these packaged cookies, a tiny amount of fruits, iceberg lettuce and some sugary dressing, cholent, lax, bagels and cake. Basically paleo death food. Also if there was really good food it would be eaten in a few minutes by congregants who swarmed on the food like a pack of piranhas. I’d personally like to see foods based on Weston Price, which actually allows all of the food groups, but properly prepares them. Also restricting the use of white sugar (cane) and nuts would probably be better for long term health of the congregation. The downside of this type of diet fix is that it will probably cost a bit more (especially if they do baked goods), be more involved to make and more likely not to ever happen. Also there tends to be a theme such as all dairy, meat or parve.
How would you propose getting healthier foods into a kiddush, that people would eat? Frugality and ease of preparation is a plus in this case.
