The U.S. Department of Agriculture (USDA) regulates whether cuts of beef can be labeled as lean or extra lean based on their fat and cholesterol content. Lean cuts of beef The USDA defines a lean cut of beef as a 3.5-ounce serving (about 100 grams) that contains less than:
â¢ High-Calcium Limestone: â¢ Magnesian Limestone: Lastly, some dolomites contain an excess of magnesium (Mg) and are called magnesian dolomite or high-magnesium dolomite. The excess magnesium is probably in the form of magnesium carbonate minerals, of which magnesite (MgCO3) is a possible candidate. It is used as a soil conditioner to neutralize acidity and to add calcium and magnesium nutrients. 2  Quicklime is calcium oxide (formula CaO) that is produced by calcining (burning) high-calcium limestone in a lime kiln to drive out the carbon in the form of carbon dioxide gas (formula CO2).
Eat less salt (sodium). A diet high in salt causes calcium to build in your urine. Too much calcium in your urine can lead to new stones. It can also cause your bones to weaken. Include the right amount of calcium in your diet. Some people may think they can keep stones from forming by avoiding calcium, but the opposite is true.
