The Samsung health app could use some visibility and clarity enhancements, especially when it comes to entering meals. When entering new items into a meal the only distinguishing factor between the search bar and selected items is the size of the icons. Otherwise they are both Grey pills with an X on the right. I frequently mistake the X for removing an item for clearing the search bar. For some reason the search bar is below entered items. People are used to the search bars either being at the top or bottom of the screen.
I would recommend moving the search bar to the bottom of the screen, in consistency with One UI's organization scheme, Perhaps putting the items selected into their own box above the search results titled "My Meal." The search bar could even be integrated into the bottom of the search results bar. Perhaps putting the days of the week above the weekly calory bars to help people with organization would be a good idea as well. Month and day is good but not all people keep account of what day of the month it is.
