Exceeding the upper limit increases your risk of health problems. Don't forget vitamin D, which helps your body absorb calcium. Food sources of vitamin D include egg yolks and fatty fish, such as salmon and tuna. You can also get vitamin D through fortified foods and even from sun exposure. Remember, these guidelines are for healthy adult men in general.
