Good for them, not for you.
A few years ago when someone would tell me they were eliminating x food or trying x diet, I would feel all this judgement come up inside me. But then I realized that if someone was talking about eliminating sugar, a family of proteins found in grains (aka gluten), dairy, or something else because it made them feel sick, it was helpful for me to recognize and say to the person that the act of eliminating those things from my life was actually what made me feel sick. Eliminating foods for some can lead to food preoccupation and can be a stepping stone towards an eating disorder or disordered eating.
A way to stand up for yourself and your health is to simply say that eliminating certain foods is what makes you feel mentally crappy and (use to or still does) begin this process of boiling down your identity and self-worth to food, exercise and body size. Okay, maybe you won’t say all that out loud…but you could.
People like to spew their latest food eliminations and if that splattering of opinions leaves you feeling like you aren’t doing the right things for your health, I’m hear to say that not eliminating a food can be the most healthy and life-giving option for you. Figuring out an elevator pitch-esque response for when someone touts about their food eliminations can be a way to practice speaking up and caring well for yourself.
