Why does my stomach think avocados are pure lard?

Your mind is associating the two, because of mouth feel and what lard looks like and feels like. It's not your stomach, it's your brain. The mid is unusually good at making associations, even across the basic senses. the people you see on TV show competitions like Fear Factor are really good at changing their mindset and turn rotten cheese covered with maggots into cotton candy.

Answer It's in your head because of the texture, the "mouth feel".

Either a gastric issue or a psychological one due to knowing they are high in fat, combined with the smooth texture (your brain thinks "lard").

I didn't know stomachs could think. Guess you learn something new everyday.

Sarcasm aside, it sounds like you're probably allergic to avocados. You might need to exclude them from your diet, for your personal health.

You might be allergic to avocadoes. My mom is.

Because like lard, avocados are full of fat.

Why do Avocados Cause Stomach Pain

Latex-Fruit Syndrome

Natural Food Chemicals

Fruit Sugar Malabsorption

Low Fiber Tolerance

In 40% of the cases, stomach pain and nausea after eating avocados is due to latex-fruit syndrome, an allergy that makes people who are allergic to latex sensitive to avocado. Avocado fiber and sugars (polyols) can cause stomach ache in people who have low fiber tolerance or can't digest fruit sugars. Chemicals like amines, glutamates, and salicylate in the ripe fruit are also potential stomach irritants.
