Thank you for your question. I am sorry to hear about your dad. As much as I would like to help all I can provide you with now is a couple of simple general pointers regarding nutritional adjustments you can make in his diet. Any thing more specific will require a more in-depth history and a proper consult.
To begin with one must remember that the older one gets the slower the metabolism. This translates into a drop in appetite and a diminished ability to tolerate large quantities of food in the digestive tract because the body simply cannot break down and absorb larger volumes any more. To over come this we want to aim for maximising nutrition while minimising volume, and incorporating more raw vegan food choices into his diet is one way to go. Blended foods, pureed foods and other softer meals make it easier for him to digest.
Secondly there are essential nutrients everyone should ensure they get enough of, either from whole food or through healthy supplementation. These include Omega 3 fatty acids, Probiotics and trace minerals.
Anything more detailed requires me to learn me to learn more about your father and what is particular concerns and preferences are. If you would like to you may call us at 0762294662 to make an appointment.
Many thanks and warm regards
