Ashworth college career diploma or AFPA certificate?

I really need your help about this, in order to make up my mind. I am Master of Business and Communication, and I wish to change my career. I’ve been thinking about nutrition courses for some time, so I can become a nutrition consultant (I know i can’t be registered nutritionist without bachelor’s degree or more). So, i was wondering, which one of those two are better for me: Ashworth career diploma for Nutrition, Diet & Health Science, or AFPA Nutrition & Wellness Consultant Certificate Course? I know they are completely different thing, but i need someone with experience to tell me which one of those two can give me more opportunities to find a work. I don’t live in the USA, so it’s bit tricky to catch all the facts about this online.
Looking forward to your answers!
Thank you!
