The key is you asked if you should be “worried” about it.
No.
“Worry” is a bad habit. You “worry” about things you can’t change.
You can educate yourself and make yourself aware of differences in various food items, then you can choose what to be concerned with and how you want to move forward. But, “worry”? Naw. It’s not worth it.
Anytime I find myself “worrying” about anything… I stop myself. There may be something I should be aware of and may need to plan for… maybe even be concerned about… but I never let myself “worry” anymore. Too stressful.
