Milk and Dairy
Milk and dairy products are satvik if taken in moderation, whereas the same becomes rajsik if taken in excessive quantities.
You may make your own cheese which is all the more best. This controversy was brought to my notice sometime earlier by someone, who obtained the data of the ingredient of manufactured cheese, which contains rennet, but the quantity of rennet found in the finished product counted one to ten-thousands of proportion, which is negligible. You may see for yourself if you can do away with it.
