Document Summary
+ phytates= decrease the mineral absorption of calcium because of opposite charges. Tofu (beans have phytates)-> although tofu has 138mg of calcium, phytates in tofu will make calcium absorption into the blood stream decreases. Amount of food equivalent to 1 serving size of milk. 1 cup of milk=1 cup of tofu=8 cups of spinach. Milk of 300mg calcium : 3. 5 cups - to supply 1000mg of calcium. Spinach : 200mg calcium: 5 cups of spinach to supply 1000mg calcium. Calcium citrate malate - 35% - fortified foods. Almond milk might be lacking is protein and potassium. Sodium - 3000mg -lose 60mg/d into your urine -> 240mg/d calcium require to offset loss. Caffeine- 100mg - lose 2. 5mg/d into your urine-> 10mg/d calcium require to offset loss. Protein -1g-lose 1. 75 mg/d into your urine->7. 0mg/d calcium require to offset loss. Iron dextran, iron sorbitol, iron sucrose, sodium ferric carbonate. Found in plant along with vitamin d and bacteria.
