These foods reduce the body’s absorption of calcium

Even eating foods rich in important nutrients to ensure the proper functioning of the body, there are some foods that combine with each other, which can affect the full or partial absorption of the vitamin compounds that we consume.

The opposite is also true, since the absorption of some nutrients is inhibited due to the incompatibility of their properties. In this context, a deficiency of certain nutrients can harm health, such as calcium, which is an essential mineral for bone development and maintenance.

Symptoms caused by calcium deficiency

Low calcium stores can cause:

  • memory problems
  • muddle
  • muscle spasms
  • cramps
  • depression
  • Bone weakness
  • irritability
  • Anxiety
  • Hypertension
  • Tooth decay and frequent dental problems

Calcium deficiency occurs due to poor intake of foods containing this mineral composition, and other problems such as hormonal changes and hypoparathyroidism can prevent absorption of the mineral.

Another reason for low iron absorption is related to a lack of vitamin D, which is a nutrient that enhances iron absorption in the body.

Foods that reduce calcium absorption

extra salt

Salt is made of sodium, and this substance causes calcium to be excreted through the urine. This way, people with bone problems cannot consume too much salt in their diet.

Caffeinated coffee and tea

Ideally, you drink no more than three cups of coffee per day. More than that, it causes calcium to be eliminated from the body.


In addition to containing caffeine, food contains oxalic acid, an element that causes calcium to be expelled through the stool. In order not to stop eating this food, the right thing is to choose options with a higher concentration of cocoa, which has an antioxidant effect, because all the evils are less.

Eating foods rich in butter and an excessive intake of meat in the diet reduces calcium absorption. This is due to the long-chain saturated fatty acids, which cooperate in the elimination of the mineral through the stool.

excess protein

Calcium is necessary for protein synthesis to occur, so eating much more protein than calcium is harmful. On average, an adult can consume between 0.8 and 1 gram of protein per kilogram of their weight per day.

The body absorbs both iron and calcium in very similar processes. When more iron is consumed than calcium, more iron ends up being absorbed.
