What food is the bane of pregnant women, calcium supplements do?

Oxalic acid - spinach, amaranth, bamboo shoots and other vegetables: pregnancy, many Yun Mami began to pay attention to eat more fruits and vegetables. However, some are astringent vegetables contain oxalic acid, oxalic acid in the intestine can be combined with the formation of insoluble calcium precipitation, affect the absorption of calcium. Therefore, the proposed Yun Mami eat vegetables, fruits can be 500 to 750 grams. Water can also be the first of these vegetables look Billy, remove astringency before cooking.



Phytic acid - rice, flour: rice and flour contained in phytic acid, calcium binding and the digestive tract, produce can not be absorbed by the body's calcium and magnesium salt of phytic acid, which greatly reduce the body to absorb calcium. Therefore, Yun Mami can first use the right amount of warm water soak rice for a while, so will most of the rice in the phytase phytic acid decomposition; and fermented flour can also secrete phytase hydrolysis of phytic acid in flour , to avoid affecting the body to absorb calcium.


Phosphate - carbonated drinks, cola, coffee, hamburgers, etc.: Under normal circumstances, the body's calcium: phosphorus ratio is 2:1, however, if Yun Mami excessive intake of carbonated drinks, cola, coffee, hamburgers, pizza , animal liver, a large number of phosphorus-containing foods such as french fries, so that Ca: P ratios up to 1:10 to 20, so that too much calcium in the body of P will "drive" out of the body.

Sodium - Salt: Excessive salt intake Yun Mami will affect the body to absorb calcium, and also may cause more calcium in human bone loss. This is because salt contains sodium and renal sodium excretion per day in vitro should be redundant, each 1000 mg of sodium excretion, they also wear and tear of 26 milligrams of calcium. So Yun Mami or in light-based diet.

Fatty acids - fats and oils: fatty acid lipolysis (especially saturated fatty acids) in the gastrointestinal tract with the formation of insoluble calcium materials to reduce absorption of calcium. Therefore, Yun Mami reasonable arrangements to diet, but do not eat at the greasy things.
