Watch Your Calcium Intake It’s true that we need calcium for healthy bones, but too much of this mineral—and too little magnesium—is a cause of osteoporosis. In the days of the caveman, the ratio of calcium to magnesium was 1:1. Today, it ranges between 5:1 and 15:1, causing an imbalance that can be deadly.
Without enough magnesium, calcium can go to the wrong places in our bodies. It can be deposited in our joints, contributing to arthritis, and in our arteries, which leads to heart disease. And, it can go to the kidneys and be turned into painful kidney stones.
