Nutrition Shapes Gene Formation

Nutrients such as folate, iron, and omega-3 fatty acids regulate epigenetic changes, turning specific genes on or off without altering DNA, affecting how your baby grows and develops. Source: unsplash

Gut Health Affects Genetic Signalling

Protein Aids Cell and Tissue Formation

Protein provides essential amino acids that form the foundation for your baby’s DNA, muscles, and organ systems. Source: unsplash

Omega 3 supports Brain and Eye Vision

Omega-3 fatty acids found in fish, chia, and walnuts enhance the activation of genes linked to brain and retinal development. Source: unsplash

Antioxidants protect DNA from Damage

Antioxidant rich foods like berries, spinach, and citrus fruits protect the foetus's genetic material from oxidative stress and DNA damage. Source: unsplash

Folate prevents Genetic Defects

Folate (vitamin B9) supports DNA synthesis and cell formation. A deficiency during early pregnancy increases the risk of neural tube defects and genetic malformations. Source: unsplash

Diet affects baby's risk of developing diseases

Poor nutrition can alter gene expression, increasing risks of metabolic conditions like diabetes, obesity, and cardiovascular diseases later in life. Source: unsplash

Iron Supports Oxygen and Gene Function

Iron helps transport oxygen to developing cells and supports the activation of genes responsible for growth and metabolism in the foetus. Source: unsplash
