Nutritional Needs Healthy Eating Tips:
You do not need any extra calories in the first trimester. Just fine-tune your diet to ensure that you are getting all the nutrients you need to build a healthy baby. A well-balanced diet rich in whole grains, fruit, vegetables, fish, lean meat and poultry, legumes and low-fat dairy products is the foundation of a nutrient-dense diet for an expectant mother. A low-fat maternal nutritional supplement may help fill the nutrient gaps in your diet. Always eat clean and safe foods.

Vital Nutrients:
Protein is needed to build muscle and tissue and form the placenta. Folic acid is critical for cell division and organ formation. Iron helps make new red blood cells. Zinc assists with growth and development.

Food Alerts:
Avoid alcoholic drinks, limit caffeine from coffee, tea, chocolates and colas. Avoid very large fishes (e.g. shark, swordfish and king mackerel) as they may contain more mercury and PCBs (polychlorinated biphenyls).

Healthy Eating Tips:
Increase food intake slightly to provide more energy and a balanced intake of protein, carbohydrate and fat. Focus on foods that are nutrient-dense, low in fat and sugar but great sources of vitamins and minerals. Include fibre-rich foods and plenty of nourishing fluids to prevent constipation. You may find that a well-designed maternal nutritional supplement may help you achieve the nutrient goals with greater ease.

Ensure adequate intake of foods rich in iron, DHA and choline. Iron-rich foods include lean meat, fish, poultry, legumes and green leafy vegetables. Fatty fish, such as herring, mackerel, sardines and salmon are good sources of DHA. Choline is found in eggs, beef, chicken, turkey, salmon and baked beans.

Vital Nutrients:
All the B vitamins and vitamins A, C and D play a part in ensuring the baby grows well. Your baby will draw calcium from your body stores to build bones and teeth. So, get enough calcium from dairy products or maternal nutritional supplements. Adequate fibre, especially FOS, will ensure you have a healthy gut.

Iron supports the expansion of your blood volume and baby’s brain growth, development of the nervous system and neurotransmitters. Lack of iron during baby’s development can negatively impact learning and behaviour. DHA helps to build baby’s brain and eyes. Choline is involved in the development of hippocampus, which is known to be the seat of memory in the brain.

Food Alerts:
If you or your husband has food allergies, avoid them. This may prevent food allergy in your baby. Also, stay away from raw foods and soft cheeses.

Healthy Eating Tips:
A healthy well-balanced diet is the foundation for good health. You will need to eat a little more and drink more fluids to meet your energy and fluid needs. Once your precious little baby is born, breast milk is the best food for your new born baby. Breast-feed your baby for the first six months of life and then, continue to breast-feed partially for as long as the baby and you want. Breast- feeding demands even more energy and valuable nutrients from the mother’s diet than pregnancy. A maternal nutritional supplement will help you achieve the nutrient goals with greater ease.

Vital Nutrients:
Include foods rich in essential fatty acids – DHA and AA – and choline to support brain growth spurt. DHA supports development of the brain and retina. Choline and phospholipids maintain cell structure and support the functioning of the cell membranes. Nucleotides are essential for normal cell function and replication, which is important for overall growth.
