I can tell you that the "gluten free" products have gotten a lot better. My grandmother was diagnosed with celiac in the late 90s early 2000s and her food choices sucked. She lived off of rice crackers and peanut butter for a while, while her doctors worked on a safe foods list. My mother in law also has celiac and what she can eat now is so much better than what was available 20 years ago.

Anyone who has a close family member with celiac should get tested every few year to make sure you don't have it yourself. It's hereditary and often is diagnosed later in life. A celiac blood panel should include total IgA and tissue transglutaminase IgA (tTG IgA) while eating a normal diet.
