Take what I say with a grain of salt, not literally though because you know sodium isn’t a good thing. Over the years I’ve come to find out with SMA we may have a harder time breaking down complex fats and proteins. Learning that explained a lot of my past issues (including a bad gallbladder.) That’s why I think the AA diet became popular. Even though I don’t follow it, I do like some aspects of it. I think it’s geared more towards tube feeding though. Basically, if I understand it right, most of the nutrients are elemental or already broken down so easier to absorb. Proteins are more plant based. Fats are reduced and there’s a heavy focus on carbs. With treatments though I’m wondering if more protein is beneficial. Maybe as long as it’s plant based? If your wanting to avoid weight gain I’d be careful about the carbs too. Overall I think you just have to find what works for you. See what the nutritionist has to say, mull it over, and do what you feel is best for your circumstances. So far nutritionists haven’t impressed me much.
