Yummy and Health Recipes for Pregnant women-1

Last Week I read a book - Nutritious Recipes for Pregnancy, the author is a Registered Dietitian, Leslie Chan.  I would like to share two delicious and health recipes to you.


If you are a lactose intolerance pregnant woman, you can choose low lactose food to absorb calcium such as cheese that can prevent you to suffer from gastrointestinal malaise.

Cheese and Eggs Pita Bread

2 pieces pita bread
2 eggs
2 slices low-fat cheese
2 slices lettuce
1 avocado
Ground black pepper

Pregnancy weight gain

Wonderful pregnant woman



Do you know how much weight gain there is in the average pregnant woman?


The answer is …………..30 pounds.

Do you know where this additional weight distribution is in the average pregnant woman?

Now, I will show you how the additional 30 pounds is distributed in the average pregnant woman.


Fetus:                                      7.5 pounds
Placenta:                                1.5 pounds
Fluid volume:                            4 pounds
Uterus:                                     2 pounds
Breast tissue:                           2 pounds
Blood volume:                          4 pounds
Maternal stores of fat,
protein and other nutrients:    7 pounds
Amniotic fluid:                         2 pounds
TOTAL:                                     30 pounds


Actually, pregnant women have a recommended weight gain which is different based on BMI level prior to pregnancy to prevent low weight gain and excessive weight gain.

BMI Level                       weight gain recommendation                       
Low (<19.8):                    28-40 pounds
Normal (19.8-26):           25-35 pounds
Overweight (26-29):       15-25 pounds
Obese >29):                    15 pounds

If you have low weight gain, you are at high risk of perinatal mortality and fetal growth restriction. For example, if your BMI is low or underweight before pregnancy, the recommended gain is 2-5 pounds in the first trimester and 1 pound each week thereafter.

If you are  obese, you are at high risk of increased blood glucose levels, high C-reactive protein levels (a key marker of inflammation), increased blood concentration of insulin, insulin resistance, increased blood pressure, increased birth weight, prolonged labor, complicated delivery, birth trauma, and asphyxia. For example, if your BMI is is very high before pregnancy , the recommended gain is 2-5 pounds in the first trimester and 0.5 pounds  each week thereafter and you should never attempt weight loss during pregnancy.

Do you know what zinc is?

  












Do you know what zinc is?

Zinc is an essential trace element that is vital for growth and development. Animal studies of zinc levels during gestation have shown that zinc deficiency is highly teratogenic in rats and leads to the development of various congenital malformations.


In addition, zinc is essential for normal brain development. If a pregnant woman has zinc deficiency, that can lead to overt fetal brain malformations. Zinc deficiency during gestation increases the risk for behavioral/neurological disorders in infancy, adolescence, and adulthood. (Adamo AM, Oteiza PI, 2010 ).

* Adequate Intake (AI)


The 2001 RDA for zinc is 11mg for those ages 19 and older during pregnancy (IOM 2001). Maternal zinc status may be inversely related to the degree of prenatal iron supplementation because excess iron ingestion inhibits zinc absorption (IOM 1990). Moreover, milk is a good source of zinc and calcium, however, high intakes of calcium may interfere with the absorption of iron and zinc.

* DV = Daily Value. DVs were developed by the U.S. Food and Drug Administration to help consumers compare the nutrient contents of products within the context of a total diet. The DV for zinc is 15 mg for adults and children age 4 and older. Food labels, however, are not required to list zinc content unless a food has been fortified with this nutrient. Foods providing 20% or more of the DV are considered to be high sources of a nutrient.
The U.S. Department of Agriculture's Nutrient Database Web site [11] lists the nutrient content of many foods and provides a comprehensive list of foods containing zinc.
