Diet plays a pivotal role in maintaining overall well-being. Specifically, the food choices made by pregnant women significantly affect both maternal and fetal health and can have long-term impacts on the child’s health. In Ayurveda, Ahara (diet) is one of the Trayopasthamba and is considered of utmost importance during pregnancy. Both Garbhini Ahara (maternal diet) and Vihara (lifestyle) are highly emphasized in Ayurveda, along with the adverse effects of improper dietary and lifestyle choices. One such dietary factor is the excessive consumption of Madhura Rasa (sweet taste), which can lead to disorders like Prameha, Sthoulya, and Mukata in the offspring. In modern times, excessive maternal sugar intake during pregnancy is a major concern, as several scientific studies indicate a correlation between maternal sugar consumption and increased risks of obesity, diabetes, and cognitive impairments in children. This article explores the long-term impact of excessive consumption of sugar during pregnancy on fetal health through Ayurveda and contemporary scientific perspectives.
