Could people with essential tremors do periodic exercises? like gym, martial arts, soccer... what the influence of the bad alimentation on et?

Having an Essential: Tremor doesn't mean that you can't have a full and active life. Now - if you have another serious medical condition that is impacting your ability to be physically active - would ask your physician about limitations.

Exercise is fine: There is NO prohibition on exercise for folks with essential tremor, but would urge use of symptomatically controlling meds to be used along with the exercise. Am not aware of any specific dietary approaches of value.
