Certain nutrients and medications may increase your need for calcium because they either lower the absorption of calcium in the gut or cause more calcium to be excreted in the urine .

How does the body work to keep calcium levels in the blood?

If calcium levels drop too low in the blood, parathyroid hormone (PTH) will signal the bones to release calcium into the bloodstream. This hormone may also activate vitamin D to improve the absorption of calcium in the intestines. At the same time, PTH signals the kidneys to release less calcium in the urine. When the body has enough calcium, a different hormone called calcitonin works to do the opposite: it lowers calcium levels in the blood by stopping the release of calcium from bones and signaling the kidneys to rid more of it in the urine.

What are some examples of anti-nutrients?

A downside to some plant foods is that they contain naturally occurring plant substances, sometimes referred to as “ anti-nutrients .” Examples of anti-nutrients are oxalates and phytates that bind to calcium and decrease its bioavailablity. Spinach contains the most calcium of all the leafy greens at 260 mg of calcium per 1 cup cooked, but it is also high in oxalates, lowering the bioavailability so that only 5% or about 13 mg of calcium can be used by the body. The takeaway message is not to avoid spinach, which contains other valuable nutrients, but not to rely on spinach as a significant source of calcium since most of it will not be absorbed by the body. You can also schedule your meals so that you do not eat “calcium-binding” foods like spinach at the same meal as calcium-rich foods or with calcium supplements.

Can You Heal Osteoporosis?

A year after breaking my hip, I had to replace it, and a couple years later, I started a two-year course of daily injections to build back my bone density from osteoporosis to normal. Simultaneously, I added more weight-bearing exercise to my training program. It began with running and hiking, and eventually, I returned to the ice as a hockey player. And of course, I continued lifting weights several times a week as I did prior to breaking my hip. During that process is when I switched from vegetarian to vegan, hence removing all dairy from my diet. A session with a nutritionist put my mind at ease when he reassured me that I was getting more than enough calcium from my plant-based diet. Enough so that I do no longer need to take calcium supplements. It turns out that the best way to build strong bones is to eat more fruit and vegetables.
