Not only are sesame seeds a very good source of manganese and copper, but they are also a good source of calcium, magnesium, iron, phosphorus, vitamin B1, zinc and dietary fiber. In addition to these important nutrients, sesame seeds contain two unique substances: sesamin and sesamolin. Both of these substances belong to a group of special beneficial fibers called lignans, and have been shown to have a cholesterol-lowering effect in humans, and to prevent high blood pressure and increase vitamin E supplies in animals. Sesamin has also been found to protect the liver from oxidative damage.
Sesame seeds are a very good source of copper and a good source of magnesium and calcium. Just a quarter-cup of sesame seeds supplies 74.0% of the daily value for copper, 31.6% of the DV for magnesium, and 35.1% of the DV for calcium.
