in my house you must eat what is best for you, us, the planet and the economy. They must be all organic, all vegan, much raw, all the time. No ifs, ands or buts ... as the old saying goes.
I would recommend that you hasten to
http://www.drmcdougall.com/Order some of his most excellent dvd presentations. In addition to any or all of Dr. McDougall's presentations, I very heartily recommend "The Pleasure Trap" by Dr. Doug Lisle. Dr. Lisle, who is a psychologist, presents some profoundly illuminating information on the difficulties facing those who change their diets and lifestyles. He does so with wit and humor.
Dr. McDougall has a grasp on the science, including up to the moment medical literature which is hidden from public view by the medical-hospital-pharmaceutical powers that be.
You have a potentially golden opportunity, a captive audience who perhaps want to know why anyone would want to keep meat off the table.
McDougall's latest "Dr. McDougall Disputes Major Medical Treatments" is spot on in its presentation of the deception of the above named powers that be.
Seriously, you are not being stinky by doing what is best for your relatives, and best for you and your conscience as well. Do not fall into the pleasure trap, but provide your loved ones with the information that they need.
Dr. McDougall also usually will respond to direct email inquiries about his programs or medical questions. He is very dedicated to the practice of informing anyone who will listen about the benefits of "one to five pounds of good food and a good pair of walking shoes."
Whatever you do, best of luck. Your guests could always have an option of going out on their own, if they feel that they must.
