The single most important thing that you can do for your baby is to eat a healthy, well-balanced diet. A well-balanced diet is one that includes foods from all food groups in appropriate amounts, so as to ensure proper nutrition. Proper nutrition ensures that all essential nutrients (carbohydrates, fats, protein, vitamins, minerals and water) are supplied to the body to maintain optimal health and well-being. Good nutrition is essential for normal organ development and functioning; normal reproduction, growth and maintenance; for optimum activity level and working efficiency; for resistance to infection and disease; and for the ability to repair bodily damage or injury. While pregnancy is a normal alternative condition for the female body, it is stressful, and all nutritional needs are increased in order to meet the needs of the pregnancy.
Dr. Tom Brewer found through more than 30 years of research that each day, pregnant women need a well-balanced, high-quality diet that includes 80 to 100 grams of protein, adequate salt (to taste), and water (to thirst), as well as calories from all of the food groups. The World Health Organization recommends that a pregnant woman eat a minimum of 75 grams of protein per day, but protein is just a marker for a nutritious diet. It must be obtained from a wide variety of whole food sources in order to get all of the important nutrients a woman needs during pregnancy. While the government's food pyramid is a good example of a well-balanced diet, pregnant women need more protein and calories in general. This means including:
2 to 3 servings of meat, fish, nuts or legumes, and tofu
2 to 3 servings of dairy (milk, eggs, yogurt, cheese)
2 servings of green vegetables; 1 serving of a yellow vegetable 3 servings of fruit
3 servings of whole grain breads, cereals, or other high-complex carbohydrates salt to taste
6 to 8 glasses of clean, filtered water each day.
While this may seem like a lot of food, it will supply the 2000 to 3000 calories needed per day to make a healthy baby.
A study conducted at Harvard University found that by eating at least 75 grams of protein per day, pregnant women could prevent diseases of pregnancy such as preeclampsia (metabolic toxemia of late pregnancy). During pregnancy a woman's blood volume increases as much as 40 to 60 percent, and in order to reach this necessary level and maintain it, a woman's body needs adequate protein, salt, calcium, potassium and water from her diet.
In April of 1996 the Journal of the American Medical Association published an article indicating that calcium may also help reduce the incidence of preeclampsia. Other recent research indicates that pregnant women need adequate folic acid (a B vitamin) to prevent neural tube birth defects such as spina bifida. The Food and Drug Administration now recommends that breads and pastas be fortified with folic acid to ensure that all women of childbearing age get enough of it. Four hundred micrograms of folic acid a day is recommended. This can be obtained by eating whole grain breads, citrus fruits and dark green leafy vegetables.
As long as junk food and excessive sweets (sugar) are avoided, or kept to a minimum, weight gain should not be an issue. The diet listed above (or something similar) should provide all of the necessary nutrients, and a woman should have little problem obtaining everything she needs. A "whole food" is one that is unprocessed and is as close to its natural state as possible. While vitamin supplements are very popular these days, there are risks to taking supplements of certain vitamins while pregnant (i.e., vitamin A), and others are simply poorly assimilated (i.e., calcium or iron). The B vitamins, for example, must be taken in congress (B complex supplement), as absences,...
