Nowadays, more attention is attached to foods that entry the body. Nutrition have great importance throughout life as well as pregnancy. The lack of specific supplements during pregnancy can be reflected in the health of a woman and a child. Recommendations for a healthy diet are different but one of the most important is to have a varied and balanced diet. Women through pregnancy should not eat for two, but increase their daily intake by only 200 to 300 kcal as much as is needed, especially after 4 months of pregnancy. Energy needs also increase because the body uses energy to grow the uterus, breasts and placenta, as well as ensuring all nutritional value for the fetus and its growth. The balanced intake of micronutrients and macronutrients through pregnancy enables normal growth and development of the baby and also maintains the health of the mother. From the macronutrients women are recommended to introduce fibers such as vegetables (especially dark green), root vegetables, fruit peel, whole wheat products, wheat bran, corn bran, nuts and seeds. Proteins are next to water the main and most important component of the organism. In pregnancy only placenta spends about 1 kg of protein. That is why recommendations for daily protein intake are 1.1 g / kg. Carbohydrates serve as a fuel to the body, can not be synthesized individually, so a woman should take at least 175 g / kg of carbohydrate daily. This input can be achieved with just a few food portions such as: fruits, vegetables and whole grains. The daily recommended amount of fat in pregnancy does not exist but fat are very important for the brain of unborn baby. Women who have been healthy in pregnancy may not have to use nutritional supplements to enter vitamins but surely micronutrients are an indispensable part of healthy pregnancy. Daily recommended intake for some of them are: iron 27 mg, calcium at least 250 mg, folate at least 0.4 mg, iodine 150 mcg and vitamin D 200 to 600 international units. Women with a varied and balanced diet should intake at least 2 liters of fluid per day, preferably water, but no other beverages are contraindicated except for alcohol that can cause alcoholic syndrome of the child. Nutrition in pregnancy in women practicing any form of vegetarian diet does not adversely affect the child or the woman until the diet reaches the recommended amount of macro and micronutrients. Women are also free to practice sports and activities in pregnancy as well as before pregnancy until it poses a risk for a woman and for a child, in pregnancy training gives women a number of benefits. Pregnancy may be associated with certain unpleasant conditions that are characteristic for pregnancy such as vomiting and nausea, constipation and hemorrhoids, heartburn or cravings for the food. All unpleasant conditions are natural and mostly pass after pregnancy. Fever or sometimes medication such discomfort is easily removed.
