After the typical discomforts of the first quarter (congratulations if you have not had any), during the second quarter there is a tendency of growth of appetite. You should eat according to your needs but keeping things under control. However, there is no need to follow any strict diet. Choose healthy food within a balanced diet and you will see that it is really quite simple.
It is time for you to enjoy your pregnancy, and this enjoyment includes food. You will probably be hungrier than usual. Just relax and don't worry too much about quantities. Use your common sense and try to eat more fruit and vegetables than usual, which will fill you up without giving you too many calories. What is best is a balanced and varied diet that meets your needs for proteins, calcium, lipids, carbohydrates, minerals, and vitamins.
What food is especially recommended during this period? Milk and its derivatives, such as cheese and yoghurt. Also, poultry, eggs, and pulses, as well as fruit, vegetables, and plenty of salads, as their fibre content will help you regulate your bowel transit and avoid constipation.
