Pregnancy Life Stage Does nutrition status affect fertility? Good overall nutrition, rather than eating any specific food, greatly improves your chances of conceiving a child. For women, nutrient deficiencies and low-calorie diets at one extreme, and obesity at the other, can disrupt ovulation. Poor nutrition can also have an impact on male fertility. In order to get pregnant, doctors recommend that both women and men eat healthy, exercise and keep a positive mental attitude to increase chances of fertilization. Eating healthy, exercise and keeping a positive mental attitude are equally important during pregnancy and after pregnancy. According to www.familyinternet.com, "carrying a baby for nine months and then providing it with breast milk afterward is a major nutritional stress on a woman's body. Food intake increases only 15-20%, but requirements for specific nutrients such as folic acid, zinc, and certain B vitamins may increase by 30-100%." In addition, less than optimal nutrition can result in low-birth weight babies with increased risk of heart disease and non-insulin-dependent diabetes as adults. (www.childbirth-connections.com). Both over-eating and under-eating can adversely affect the qualities and quantities of breast milk, which is explained further under Dietary Requirements During Pregnancy.

However, during the pregnancy cycle, nutrition is of even greater importance because of the effects on both the mother and baby. Many people have said that a pregnant mother is eating for two, which in fact is correct. The mother needs a certain amount of protein, carbohydrates, fat, vitamins, water and fiber in the diet each day. Pregnancy Life Stage One suggested food plan, developed by FamilyWeb.com, suggests that during the first 2 to 3 months of pregnancy, a woman should try eating small amounts frequently throughout the day to keep the energy higher. If the mother only eats larger amounts of food less frequently, she may experience discomfort due to her energy levels reaching highs and lows. The food plan also recommends that the mother eat raw vegetables, fruits, juices, milk, breads and cereals in between meals as a way to keep the metabolic rate and energy steady. Each food group has recommended or suggested serving amounts for a pregnant woman. An outline of the serving amounts for each food group is as follows: The Five Food Groups Suggested Number of Servings Fruits and vegetables 4 or more Milk and dairy products 4 Meat, fish, poultry, eggs, dried beans, peas and nuts 3 or more Whole grains, enriched breads and cereals 9 or more Fats and sweets Vary according to calories needed It is very important that, during pregnancy, that the mother eats the suggested amounts from each of the food groups in order to maintain a balanced diet and healthy nutritional intake.
