if you and family are sensitive to MSG… maybe also look into avoiding foods that naturally have MSG in them – afaik that includes things like broccoli and chicken for example
re tremors- ime sometimes … they can have a v simple, but all too often overlooked/disregarded cause- posture and ‘holding unnecessary tension’
I’ve had episodes of tremors in arms/hands and loosening shoulder/neck/arm muscle tension and correcting posture can stop them- same for my mum who got dxed with “old age tremors”… yet when she hasnt got her shoulders ’round her ears’… no tremor…
pity enough due to in part our proprioception issues we have a tendency to ‘grip/hold/do’ things with far too much muscle tension- so doing things in a ‘normal/fairly relaxed’ way is quite hard ‘brain work’ (we have to ‘consciously’ do things rather than ‘just do’)
