Consuming too many foods high in OXALIC ACID will decrease calcium absorption. Studies have found that boiling reduces the level of oxalic acid in food. Boiling spinach reduces oxalic acid by 87 percent whereas steaming reduces it by 42 percent. In every vegetable studied, boiling is more effective than steaming. And here’s why: oxalic acid falls off food and into the water. Use the water on your plants or lawn. So, boil (or at least steam) the food, then discard the cooking water.
