Pregnancy brings profound changes to a woman’s physiology and dietary requirements to sustain the growth and development of the fetus. The quality of maternal nutrition is a key determinant of fetal well-being and may have enduring effects on offspring, including susceptibility to metabolic and chronic diseases later in life. Research, including studies from the Dutch famine, underscores the importance of nutrition during pregnancy in determining future health risks for offspring. While nutrients like folic acid are well-known for preventing neural tube defects, many other nutritional relations remain unclear due to the complexity of conducting clinical trials with pregnant populations and the ethical challenges of studying these effects. Achieving favorable pregnancy outcomes requires a balanced and varied diet emphasizing nutrient-dense, unprocessed foods. A healthy pregnancy diet should feature a variety of brightly colored vegetables, particularly green, red, and orange ones, complemented by legumes, whole grains, dairy foods, lean meat, poultry, fish, nuts, seeds, and unsaturated fat sources. A fundamental aspect of healthy eating during pregnancy is minimizing the intake of highly processed foods and sugary beverages that contribute empty calories and may adversely affect both maternal well-being and fetal development. Moreover, daily caffeine consumption should not exceed 300 mg. Regarding macronutrient distribution, pregnant women are advised to consume approximately 1.1 g of protein per kilogram of body weight daily during the second and third trimesters. The recommended carbohydrate intake rises to about 175 g per day, while a dietary fiber intake of 28–36 g is encouraged to alleviate or prevent constipation commonly experienced during pregnancy.
