13. Rhubarb
Bake yourself a rhubarb pie this weekend, and enjoy this high-calcium food with a side of custard as a special treat to reward yourself after a hard week at work and the gym. Rhubarb contains 350-grams of calcium per cup, making it extremely rich in this vital mineral.
However, before you decide to feast on rhubarb every day, it’s important to note that it contains significant quantities of oxalates. Oxalates reduce the body’s absorption of calcium by up to 75-percent. However, that means you’re still getting almost 90-grams of calcium preserving.
People with kidney issues may want to avoid eating foods rich in oxalates, as they may induce the formation of kidney stones. IF you don’t have any kidney issues, then eating rhubarb not only tastes great, and provides you with a healthy serving of calcium, it also contains beneficial prebiotic fiber that keeps your gut biomes happy and healthy.
