- Even though most dark leafy greens are rich in calcium, broccoli, rapini, turnip greens, collard greens and mustard greens are better sources than spinach, chard and beet greens because of the high oxalic acid content that blocks absorption of the calcium in spinach, chard, and beet greens.
- Calcium-rich vegetable / fruits and greens are: bok choy, kale, parsley, mustard greens, cabbage, broccoli, carrots, dandelion greens, apricots, figs, endive, okra, garbanzo beans (chickpeas), pinto beans and kidney beans. Please note that large raw beans - such as Anasazi, Black, Fava, Kidney, Lima, Navy, Pinto, and Soy - can cause toxicities when fed raw, causing digestive upsets for people and potentially for birds. Some experts recommend that large beans should be cooked to make them safe and digestible. Others counter that soaking beans for 24 hours starts the germinating process and that soaking makes the beans safe and digestible. For those who do not want to take any risks, it's best to cook large beans thoroughly before feeding to your birds. These beans are not recommended for general sprouting purposes. Certain uncooked dried beans contain enzyme inhibitors, are indigestible , and may cause visceral gout in birds. These enzyme inhibitors may prevent or decrease the utilization in the body of substances, such as trypsin and chymotrypsin, to produce nutritional deficiencies. Beans that can interfere with proteolytic enzymes are lima, kidney and soybeans. Cooking these beans for at least 2 hours destroys these enzyme inhibitors. Other dried beans do not appear to contain these enzyme inhibitors or, if present, are in low concentrations. To be on the safe side, it's best to cook ALL varieties of beans.
- Other food sources of calcium: Baked eggshells, crushed and sprinkled over the food, oatmeal, almonds, walnuts, hazelnuts, sesame seeds, and tahini -- "nut butter" made of sesame seeds
