Does phytic acid inhibit calcium absorption?
Phytates (phytic acid) in whole grains, seeds, legumes, some nuts—can decrease the absorption of iron, zinc, magnesium, and calcium.
How do phytates and oxalates inhibit calcium absorption?
It has a very high affinity for binding minerals such as calcium, iron, magnesium, and zinc. When phytic acid binds these minerals, it makes them unavailable for absorption. This means that your calcium intake can be lower than expected if you consume notable amounts of food containing phytates.
Does phytic acid affect calcium?
Phytic acid prevents the absorption of minerals such as iron, calcium, manganese, and zinc by binding to them before your body can absorb them. Plants store phosphorus in a compound known as phytic acid. Phytic acid can bind to other minerals, such as those mentioned above, and in doing so creates phytates.
How does oxalate and phytate affect the bioavailability of calcium?
Phytic acid in cereals and pulses inhibit the absorption of calcium from food, as do oxalates present in some types of vegetables. Other foods such as lactose and non-digestible polysaccharides increase calcium absorption.
Does oxalic acid inhibit calcium absorption?
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.
Does phytic acid block mineral absorption?
People sometimes refer to phytic acid as an anti-nutrient, because it blocks the absorption of certain minerals into the body. When you eat foods high in phytic acid, the molecules bind with certain minerals in your digestive tract, including: Calcium.
Does phytic acid inhibit iron absorption?
Phytic acid is a potent inhibitor of native and fortification iron absorption and low absorption of iron from cereal- and/or legume-based complementary foods is a major factor in the etiology of iron deficiency in infants.
How do oxalates affect calcium absorption?
Oxalate can reduce mineral absorption One of the main health concerns about oxalate is that it can bind to minerals in the gut and prevent the body from absorbing them. For example, spinach is high in calcium and oxalate, which prevents a lot of the calcium from being absorbed into the body ( 3 ).
How does oxalic acid affect 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.
Does oxalic acid dissolve calcium?
Nutritionists refer to oxalic acid as an anti-nutrient because it interferes with the essential minerals, iron, magnesium and especially calcium.
