Just a quick chat with a dietitian would be helpful!
Then lots of long and involved sessions with a therapist!
But a dietitian first!
You're just desperately confused that someone can eat fat with impunity, yet eat so little. Yeah, welcome to my freedom.
Talking to a predatory industry sales agent who likely has orthorexia is irrational(no sane person would spend their 20s thinking that deeply about food unless they are insecure about something). Promoters of "hamster wheel slavery", they are. Not only have they not helped health. They've helped murder real quality European food culture like those of the French and Italians. Oh, and I can make female ones dead jealous that I'm at a lower weight than they are while having access to most pleasure foods besides clingy sweet pastries and candies.
They will not pry the pork belly from my cold dead Chinese hands(both bacon and hong shao rou).
You're probably just jealous that I have no worries about weight or food beyond the mere practical matter at hand.
The science is there.
Mouth bacteria/fungi can enter the bloodstream and spread elsewhere.
Sucrose is processed by S. mutans into a biofilm that then assists
Sardines cover the bases for proteins, DHA, and EPA
Pasture-raised eggs cover vitamin K, protein, some fat, and numerous other micros
Blackberries covers vitamins, potassium, etc
Saturated fat covers celluar membrane strength
Monounstraturated fat covers celluar flexibility
And I still get to enjoy the proteins.
Greens cover numerous vitamins and minerals as well, along with antioxidants and other chemicals not yet firmly established as being good.
I'm pretty well set in health since all the essential nutrients are covered and I have no intention to stop eating them.
Grains exist only because they help stretch a budget.
