Protein deficiency in Pregnancy

I like eat boiled egg white, because I like the smooth texture and egg white is complete with proteins providing adequate amounts of all nine essential amino acids.

Proteins are one of the three energy-yielding macronutrients. 1gram of proteins provides 4 calories and they are made up of amino acids. The body needs 20 amino acids. These amino acids can be classified as essential, nonessential, or conditionally essential. Eleven are synthesized i-in our body.  There are nine essential amino acids which should be included in our diet because these amino acids cannot be synthesized in our bodies.

Besides, most plant foods are incomplete proteins which lack adequate amounts of one or more of the essential amino acids. If you are a vegetarian, you can take different types of plants in the same meal to get a combination that provides adequate amounts of essential amino acids for human protein synthesis in the body and prevent deficiency of proteins during pregnancy.

Pregnant women should prevent protein deficiency during pregnancy. It is because proteins are important for building structure of tissues and maintaing fluidbalance between plasma and the interstitial fluid. Moreover, enzymes and hormones are made of protein which facilitates chemical reactions and regulates some of the body’s processes.

During the third trimester, protein requirements increase throughout gestation and peak. A pregnant woman and her growing fetus use proteins for growth and maintain a positive nitrogen balance. Therefore, pregnant women have additional protein requirements to support their babies to synthesize material and fetal tissues.

Calcium Deficiency

In our body, ninety-nine percent of the calcium is in the bones and teeth and 1% is in the blood. Calcium is an integral part of bone structure and has many functions such as activation of muscle contraction, activation of a protein, helping blood clot, and regulation of enzymes.

According to Dietary Guidelines for Americans 2010, the recommended calcium intake is:

For pregnant women less than 18 years of age: 1,300 mg/day

For pregnant women 19-50 years of age: 1,000 mg/day

resource: http://www.babycorner.in/parents-checklist/nutrition-for-pregnant-women/

Pregnant women accumulate calcium mostly during the 3^rd trimester.  Calcium metabolism is influenced by hormonal factors in pregnant women that promote calcium retention to meet increasing fetal skeletal growth, formation of teeth and adequate supply of calcium for breast feeding. Calcium deficiency affects the heart and circulatory system and normal bone formation.  For instance, if pregnant women have a calcium deficiency, they not only may develop osteomalacia because of loss of maternal skeleton but it would also affect fetal skeletal growth.

Osteomalacia will cause the patient to have some symptoms such as muscle weakness and bone aches and pain. Moreover, patient’s bones become soft due to a vitamin D deficiency. Actually, pregnant women consume adequate vitamin D which helps to maintain calcium balance during pregnancy. However, excessive consumption of vitamin D supplements may be harmful during pregnancy. 

According to Dietary Guidelines for Americans 2010, “vitamin D is unique in that sunlight on the skin enables the body to make vitamin D. Moreover, you also consume milk and milk products contribute many nutrients, such as calcium, vitamin D (for products fortified with vitamin D), and potassium, to the diet.”

Iron deficiency

Source: http://www.ezinenewsarticles.com/pre-and-early-pregnancy-iron-deficiency-harms-brain/

During pregnancy, women need 27 milligrams of iron intake a day to make hemoglobin that carries oxygen from their lungs throughout their bodies and her blood volume expands to accommodate the change in her body. Blood tests may reveal low hemoglobin levels signifying anemia. Actually, iron deficiency is very common nutritional disease especially among pregnant women. Iron is very important to help her baby make his or her entire blood supply which is why pregnant women need double the normal iron intake.

Recommended Dietary Allowances for Iron for Infants (7 to 12 months), Children, and Adults [1]
Age	Males (mg/day)	Females (mg/day)	Pregnant (mg/day)	Lactating (mg/day)
7 to 12 months	11	11	N/A	N/A
1 to 3 years	7	7	N/A	N/A
4 to 8 years	10	10	N/A	N/A
9 to 13 years	8	8	N/A	N/A
14 to 18 years	11	15	27	10
19 to 50 years	8	18	27	9
51+ years	8	8	N/A	N/A

There are many reasons for iron deficit in pregnant women such as not enough iron-rich food intake in the diet, consumption of foods containing inhibitors of iron absorption resulting in insufficient bioavailability, vegan diet, menorrhagia and anemia during a previous pregnancy are some of the important factors responsible for iron deficiency.

Iron deficiency anemia during pregnancy can increase risk for preterm babies and low birth weight. It is because iron is needed for deposition fetal stores and inadequate maternal iron intake is linked with delivery of low birth-weight infants (LBW) which means their birth-weight is not more than 2500g (5.5 lb). LBW is the single greatest risk factor for survival of newborn babies.

Actually, most specialists in Obstetrics & Gynaecology recommend pregnant women take an iron supplement. Eating iron-rich foods such as lean red meats, poultry, and fish can increase heme iron which is  easier for the human body to absorb than non-heme iron.
