I’ve fretted here before about possible inadequate calcium intake on typical paleo diets. Colin Champ, M.D., otherwise known as CavemanDoctor, has a way around it. A quote summarizes his ideas:
- Calcium levels and bone health are multifactorial and calcium intake is just the tip of the iceberg.
- Don’t count on dairy for calcium and instead get it naturally in highly absorbable forms in the foods nature laid out for you.
- Instead, avoid foods that result in decreased absorption and increased excretion of calcium like milk.
- Get some sun (not sun burns) or if that is not possible, take some vitamin D3.
- Lift heavy weights and sprint as the heavy loads stimulates bone mineralization and decrease bone breakdown.
- Avoid chronic stress and the increase in glucocorticoids that results.
- Increase your highly absorbable sources like green leafy vegetables, and decrease poorly absorbable sources like milk, and avoid its downside with its large amounts of lactose (sugar).
- Avoid large amounts of carbohydrates that cause significant insulin release and calcium loss in the urine.”
