27 vegetables high in calcium - June 2020

Because arugula is made up of more than 90% water, it is very low in calories (only 4 calories per cup!), so it is possible to easily eat 3 or 4 cups of it in one sitting. Apart from calcium, arugula contains a compound called erucin, which is thought to have cancer fighting properties .

What Is the Difference Between Sodium and Salt?

2019/8/8· Sodium is 23/58.5 x 100% = 39.3% of salt is sodium. Then the amount of sodium in 3 grams of salt = 39.3% x 3 = 1.179 g or about 1200 mg. An easy way to calculate the amount of sodium in salt is to realize 39.3% of the amount of salt comes from sodium. Just multiply 0.393 times the mass of the salt and you will have the mass of sodium.
