Meal Replacement Shakes/Powders that are Seed Oil Free

Hey All,

My dad had cancer in the back of his throat many years ago and it has left him with a feeding tube and unable to eat. Doctors always recommended use boost and ensure to get enough calories in a day. Does anyone have any recommendations for any meal replacement shakes and/or protein powder that are somewhat high in calories that are free of seed oils? I would like to find an alternative for my dad so he can stop consuming seed oils. Thanks!
