Hmm idk about the salary but if you are good at it amd you know someone around football you can be a nutritionist for a football teams. Ik it seems a long shot in our country gn since the coach ands players don't know the benefits how good nutrition will help them gn ik some teams like st George have nutritionist and they pay good. Google it and see the Europe teams nutritionist's salary, you will be amazed. Hope it helps
