What can block calcium absorption?

Key Factors

• A diet high in phytic acid — Found in the bran coating of whole grains, phytic acid binds calcium and other minerals, making them insoluble and not absorbable in the intestines.
• High levels of sodium — Excessive salt can interfere with calcium absorption.

Do oats block calcium?

1) Soak your oats Grains contain phytic acid, which, when untreated, combines with calcium, magnesium, copper, iron and zinc within the intestinal track. This results in the blocking of the absorption of these minerals.

Do eggs block calcium absorption?

Why do eggs help? It’s likely the vitamin D content. Vitamin D helps increase the absorption of calcium. And while the mighty egg doesn’t contain calcium, it is packed with vitamin D to ultimately build stronger bones.

Does coffee deplete calcium?

Caffeine leaches calcium from bones, sapping their strength. “You lose about 6 milligrams of calcium for every 100 milligrams of caffeine ingested,” Massey says. That’s not as much of a loss as salt, but it’s worrisome, nonetheless.

Are there certain foods that block calcium absorption?

There are certain foods, like wheat, that block calcium absorption.

When to take calcium citrate with or without food?

Calcium citrate is absorbed equally well when taken with or without food and is a form recommended for individuals with low stomach acid (more common in people over 50 or taking acid blockers), inflammatory bowel disease or absorption disorders.

What foods are high in oxalic acid and calcium?

Oxalic acid hinders calcium absorption. Foods high in oxalic acid also impede the absorption of calcium by binding the mineral. Spinach is naturally high in calcium, but it is also high in oxalic acid. The body is unable to process the calcium it provides. Other foods that contain oxalic acid include beet greens, rhubarb and sweet potatoes.

What foods are low in calcium and high in vitamin D?

According to American Bone Health, a diet high in phytic acid (which can be found in beans, Brazil nuts, hazelnuts and more) and sodium, as well as one low in vitamin D, can lead to poorly absorbed calcium.
