It's not necessarily intuitively obvious. My mother has scary high cholesterol and I have freaky low cholesterol. My mother is often low on iron and I'm well-ironed. My mother has a life threatening allergy to codeine and I found it delightful after they put my foot back together.

Of course, she loves seafood and it would kill me. But yeah, I guess the mother + sisters would suggest a tendency. Do you take supplements?
