Aio or my friend is being rude?

Background- Food is a main part of this country that I come from. Whereas my friend is american but with my country's ethnicity so she is fully aware of our culture and cuisine and has eaten the dishes on daily basis / occasionally. We have (had.. because i don't feel comfortable anymore)a habit of sending eachother their meal pics but she always calls my food "diarhea" looking or gross or not appetizing which feels more like racist remarks rather than genuine advice. You can't simply call a dish as feces because it is brown. I have let her know that I do not appreciate such comments as it is not something people can work on, it is our culture. You can't just slap on some bread and mayo alongside my dish to make it look "aesthetic", it is how it is. But she ends up giving a light apology everytime and goes on to comments the same whenever I sends her the pic while she mostly have sandwich, or burger or sushi or taco or burrito which I have never called "weird" looking or even gross. I was really hurt by her such statement and didn't communicate for a day only for her to say "atleast i didn't say your family is inbred or something that you are this mad for. Its just a food". Genuinely speaking, how does that statement makes whatever she said any Better? Thats like saying "oh you got rpd? Atleast you weren't beheaded" both statements are equally bad. And then proceeded to tell me to join a cooking class to make my dish look "aesthetically pleasing" whereas my dish is literally prepared that way in our country and doesn't lack flavorwise.

So, the question, Am I overreacting? And what can I tell my friend to make her understand that she is sounding racist and rude here.
