I have been following the Swank/Jelinek model for over a year now, although I had been a vegetarian since the mid-1970s.
As you know, the diet is essentially vegan but supplemented occasionally with oily fish, with the idea of minimising your saturates intake; the main culprit for this in a vegan diet is, of course, coconut. In addition, I drink some home made kefir, based either on coconut or hemp milk, every day and I eat plenty of kimchi. Wonderful stuff.
What are the benefits? Well, there are plenty of interesting foods to eat and plenty of recipes. It keeps me alert for most of the day, possibly due to the elimination of dairy products, and I just feel a lot healthier. It is also essential for maintaining a good weight, now that I am less mobile, which also helps with self-esteem.
It is one weapon in my armoury against MS; the others being mainly exercise, Vitamin D 5000iu daily, CBD products and Biotin. I believe that this combination works for me and enables me to live well without the need to take any prescription medicines such as Gabapentin.
Keep filling your head with stuff (read papers and books), listen to music, go to concerts and the theatre as much as is possible. I am now restricting myself to daytime concerts as I seriously flag in the evenings.
I am sorry to have gone off on a tangent. I hope you find a diet that works for you.
