You are fortunate if you have created a taste for “raw” food. Certainly, it is a great choice. In my experience at work, whenever there is a “party” (once every month at least) fortunately they have fruit platters or veggie platters as well. I would pick a couple of items and mingle with the people and extend my “eating time.” Other times I have been offered to eat their lasagna or pizza or something else. Here is where my “list of allergies” and the “severe punishment” that I receive after indulging in such tasty food items, comes in handy.
I am “allergic” to onions and garlic (so everything they cook, have those items) and they know that I am vegetarian, and it is viewed as something “good” which if they had the “will power” to do it, they would do it.
I would stick with “raw” food so, issues will not appear when mingling with people. That includes your relatives as well. If you would like to eat a cooked item, it is much better to do it yourself.
As you know we are “numberwise” so, whatever I have stated above is just my own way of tackling those issues. By the way, I am considering increasing the amount of “raw” food items into my diet. I have never liked to cook. It is something which does not come “naturally” to me, but I have seen the benefits and that is what matters to me.
