Requirements of nutrients during pregnancy
During pregnancy the daily protein needs are very high. The proteins used to create the placenta, the tissue through which nourishes the fetus, and to create new tissues of the embryo. The surplus is converted into glucose and used by a ton body as an energy source.

Protein-rich foods are eggs, milk, fish and seafood, poultry, red meat, peas, corn, bran, spinach, beans, bread, etc.

Carbohydrates

Part of the necessary for the functioning of the body energy provided by carbohydrates and fat. 55% of daily calories should come from complex carbohydrates mainly for both normal subjects and for pregnant women. Good sources of carbohydrates are pasta, rice, flour, potatoes, bread, legumes, fruits and vegetables.

In the category of carbohydrates are also sugars, starch and fiber. While sugars and starch are easily absorbed by the body, not the case with fiber, which essentially have no nutritional value. However, the diet of pregnant women is important to include fiber, as they affect the transit time of food in the gut in water absorption and binding of trace metals, thereby helping to tackle constipation and hemorrhoids.

Natural carbohydrates are the full meal, the black bread, honey, etc. Processed carbohydrates such as white sugar or flour, have the same nutritional value as natural and devoid of fiber and are removed during processing.

Fat

During pregnancy the fat is stored more easily than under normal conditions, and that's why the mechanism of deposition of fat tissue during pregnancy triggered by the production of certain hormones. Therefore, during pregnancy, the consumption of fat should amount to 25-30% of daily calories and no more (80-100 g / day for a normal pregnant and 40-50g / day for obese pregnant).
