I couldn't find out the method to remember it . I just write down topics hard to remember and reread them ones in 1-2 month. Good luck.

from what i learned from my instructor at school foods that are high in sodium are root crops or those found below the ground e.g potato, ginger( ginger ale) and canned foods, milk and tomato are also high in salt.Foods that are high in potassium are those 'hanging above the ground' like fruits. As to calcium i just think about "white stuff" like milk and dairy products also rice is also rich in calcium.
