Yes, stainless steel mugs are good for health. Stainless steel mugs don’t leak the chemical to the coffee like plastic made coffee mugs. Scientifically stainless steel mugs cannot affect the flavor & taste of the coffee. Steel is a solid inert compound, even when shaped like a cylinder like a mug and poured with a boiled beverage, there is no chemical reaction which means this is good for your health. You can keep faith in stainless steel mugs for your good health.
