There are six essential nutrients that people need to consume through dietary sources to maintain optimal health. The WHO divide these essential nutrients into two categories: micronutrients and macronutrients. Micronutrients are nutrients that a person needs in small doses. Micronutrients consist of vitamins and minerals. Although the body only needs small amounts of them, a deficiency can cause ill health. Macronutrients are nutrients that a person needs in larger amounts. Macronutrients include water, protein, carbohydrates , and fats.

Food is not a source of nutrients in its original form and is not absorbed into the cells and blood unless first broken down into small blocks. This process-digestion-takes place in the digestive tract, where it is then absorbed by the intestines, transported in the blood stream to each organ, and then taken up into cells. Digestion and absorption begin at the mouth, where food is chewed and swallowed. From there, it moves down the esophagus food pipe to the stomach, where it is thoroughly broken down. Our bodies are built of and powered by solely what we eat and drink.

Nutritional status during pregnancy can have a significant impact on maternal and neonatal health outcomes. Requirements for macronutrients such as energy and protein increase during pregnancy to maintain maternal homeostasis while supporting foetal growth. Energy restriction can limit gestational weight gain in women with obesity; however, there is insufficient evidence to support energy restriction during pregnancy. Modulating carbohydrate intake via a reduced glycaemic index or glycaemic load diet may prevent gestational diabetes and large-for-gestational-age infants. Certain micronutrients are also vital for improving pregnancy outcomes, including folic acid to prevent neural tube defects and iodine to prevent cretinism. Newly published studies support the use of calcium supplementation to prevent hypertensive disorders of pregnancy, particularly in women at high risk or with low dietary calcium intake.
