Consumption of a Western-style diet during pregnancy, characterized by high intake of fat, sugar, and processed foods along with low nutrient density, has been associated with elevated risks of ADHD and autism in children.
According to new research, adherence to the unhealthy characteristics of a typical Western diet during pregnancy is associated with elevated risks of neurodevelopmental disorders in offspring. Even modest deviations toward this pattern were linked to a 66% increased risk of ADHD and a 122% increased risk of autism.
The large-scale study analyzed dietary patterns, blood samples, and ADHD diagnoses from over 60,000 mother-child pairs, with nearly 600 children clinically assessed for neurodevelopmental disorders at age 10. Metabolomic analysis of blood samples revealed key biological links between maternal diet and increased risk of ADHD and autism.
Researchers identified 43 metabolites in maternal blood linked to a Western diet that help explain the connection to neurodevelopmental disorders. The first and second trimesters were identified as critical periods, when poor diet showed the strongest association with future ADHD and autism diagnoses.
Pregnancy dramatically raises nutritional demands, and this research clearly demonstrates how crucial a mother’s diet is for her child’s brain development. These insights help identify key nutrients and dietary changes that can reduce the risk of neurodevelopmental disorders, supporting more effective guidelines for healthier pregnancies and better outcomes for children.

Muscles are essential to keeping the body healthy and functioning well. In addition to allowing us to move, they help regulate blood sugar, support metabolic health, and protect our joints while helping us remain independent. Yet, as we grow older, muscle strength and size naturally decline. This gradual loss can affect stability, raise the risk of falls, and make it take longer to bounce back after an injury or illness.
The strength of the skeleton is often assessed by measuring bone mineral density, which reflects how well bones can withstand damage and resist fractures. According to research, changes in the skeleton could also provide important clues about cognitive aging. A new study points to a potential connection between reduced spinal bone density, changes in the brain, and a more rapid decline in brain aging.
Many Americans consume soybean oil regularly, often without realizing how frequently it appears in processed foods. Researchers are now investigating whether this widely used ingredient may play a part in the development of obesity. In a study involving mice, scientists compared the effects of different fats on weight gain and metabolism, focusing primarily on soybean oil.
