Shavuos is a fun holiday in lots of ways, mostly because we get to eat dairy products at our festive meals, making for a lovely change of pace. Cheesecake and blintzes are traditional. But considering that 70 percent of Jews are lactose intolerant, one wonders why we have a holiday where we eat something that makes us feel unwell?
The answer, of course, is that it’s only a tradition. No one has to eat dairy products on Shavuos. At any rate, today there are enzyme supplements one can take to make dairy easier to digest for sufferers.
