Nutritional Deficiencied and ASD link?

Wondering if low potassium, magnesium, sodium etc are common w/ASD folk. I have always been very thin, can’t get enough nutrition and I eat healthy. I am once again on prescription strength potassium and magnesium mainly cuz I was getting lots of arrythmias.
My mom said I had to be awakened for all my infant feedings. Seem to have little appetite though I LOVE to eat!!!
Anyone had past nutritional deficiency problems

Yes, I’ve had those same issues! I have had to supplement.
